5. Jack has a 35-foot ladder leaning against the side of his house. If the bottom of the ladder is 21 feet away from his house, how many feet above the ground does the ladder touch the house?
Therefore, the ladder touches the house at a height of 28 feet above the ground.
What is triangle?A triangle is a geometric shape that consists of three straight sides and three angles. It is a polygon with three sides. The sides of a triangle are connected by its vertices or corners. The triangle is one of the simplest and most fundamental shapes in geometry, and it has many important properties and applications. Triangles have many practical applications in everyday life and in various fields, such as architecture, engineering, and physics. The study of triangles and their properties is an important part of mathematics and geometry.
Here,
We can use the Pythagorean theorem to solve this problem. The Pythagorean theorem states that in a right triangle, the sum of the squares of the lengths of the legs (the two shorter sides) is equal to the square of the length of the hypotenuse (the longest side, which is opposite the right angle). In this problem, the ladder, the side of the house, and the ground form a right triangle. The ladder is the hypotenuse, the distance from the house to the ladder is one leg, and the height we want to find is the other leg.
Let x be the height above the ground where the ladder touches the house. Then, using the Pythagorean theorem, we have:
x² + 21² = 35²
Simplifying and solving for x, we get:
x² + 441 = 1225
x² = 784
x = 28

Sketch the graph of 2x²+4x
We can sketch the graph of 2x²+4x.
We can start by dissecting the equation and identifying its main components before drawing the graph of 2x²+4x.
The formula reads as y = ax² + bx + c, where a = 2, b = 4, and c = 0. It is a quadratic function.
The upward opening of the graph is indicated by the positive coefficient of x2 (a). By applying the formula -b/2a, which in this case equals -4/4 = -1, one can determine the vertex of the parabola.
Hence, the parabola's vertex is located at (-1,0).
By setting y = 0 and solving for x, we may get the graph's x-intercepts:
0 = 2x² + 4x
0 = 2x(x + 2)
Hence the x-intercepts are at x = 0 and x = -2.
We can set x = 0 to determine the graph's y-intercept:
y = 2(0)² + 4(0) = 0
The y-intercept is therefore at (0,0).
Using this knowledge, we can draw the 2x²+4x graph as follows:
Vertex located at (-1,0).
x = 0 and x = -2 are the two x-intercepts.
Y-intercept is located at (0,0).
The graph has a "U"-shaped opening that faces upward.

The first three questions refer to the following information: Suppose a basketball team had a season of games with the following characteristics: 60% of all the games were at-home games. Denote this by H (the remaining were away games). 25% of all games were wins. Denote this by W (the remaining were losses). 20% of all games were at-home wins.
Of the at-home games, what proportion of games were wins? (Note: Some answers are rounded to two decimal places.)
.12
.15
.20
.33
.80
Answer:
25 I am not sure
Step-by-step explanation:
The proportion of at-home games that were wins is 0.33, or 33%.
The proportion of at-home games that were wins can be found by dividing the number of at-home wins by the number of at-home games. This can be represented as a fraction:
At-home wins / At-home games
Using the information given in the question, we can plug in the values for at-home wins and at-home games:
0.20 / 0.60
Simplifying the fraction gives us:
1/3
Converting this to a decimal gives us:

Given the point (5,8) and y intercept of -2, calculate the slope
The slope of the line is 2, which was calculated using the slope-intercept form of a linear equation and the given point (5,8) and y-intercept of -2.
To calculate the slope, we need to use the slope-intercept form of a linear equation:
y = mx + b
where m is the slope and b is the y-intercept.
We are given that the point (5, 8) lies on the line, so we can substitute x = 5 and y = 8 into the equation:
8 = 5m + b
We are also given that the y-intercept is -2, which means that when x = 0, y = -2. We can use this information to find b:
-2 = 0m + b
b = -2
Substituting this value into the equation above, we have:
8 = 5m - 2
Solving for m, we get:
5m = 10
m = 2
Therefore, the slope of the line is 2.

Make x the subject of the formula a/b = 2x/x+5
When x is the subject of the formula a/b = 2x/x+5, the value of x = 5a/(2b - a).
What are variables?The alphabetic letter that conveys a numerical value or a number is known as a variable in mathematics. A variable is used to represent an unknown quantity in algebraic equations.
Any alphabet from a to z can be used for these variables. Most frequently, the variables "a," "b," "c," "x," "y," and "z" are utilised in equations. By performing mathematical operations on variables as if they were express numbers, one is able to handle a variety of problems in a single computation. A quadratic recipe is a common example that demonstrates how to explain each quadratic condition by simply substituting the numerical estimates of the condition's coefficients for the variables that correspond to it.
The given formula is:
a/b = 2x/x+5
To make x the subject of the formula we have to isolate the value of x.
Using cross multiplication we have:
a(x + 5) = b(2x)
ax + 5a = 2bx
5a = 2bx - ax
5a = x (2b - a)
5a/(2b - a) = x
Hence, when x is the subject of the formula a/b = 2x/x+5, the value of x = 5a/(2b - a).

as in the previous problems, consider the model problem (4.3) with a real constant a < 0. show that the solution of the trapezoidal method i
The solution yn+1 is always less than or equal to yn, which means that the solution is stable for a < 0. Therefore the solution is of trapezoidal method.
The model problem (4.3) with a real constant a < 0 is given by:
[tex]y' = ay, y(0) = 1[/tex]
The trapezoidal method is given by:
[tex]yn+1 = yn + (h/2)(f(tn, yn) + f(tn+1, yn+1))[/tex]
where h is the step size, tn and yn are the current time and solution values, and [tex]f(t, y) = ay[/tex] is the right-hand side of the model problem.
To show that the solution of the trapezoidal method is stable for a < 0, we can substitute the right-hand side into the trapezoidal method and solve for yn+1:
[tex]yn+1 = yn + (h/2)(ayn + ayn+1)yn+1 - (h/2)ayn+1 = yn + (h/2)aynyn+1(1 - (h/2)a) = yn(1 + (h/2)a)yn+1 = yn(1 + (h/2)a)/(1 - (h/2)a)[/tex]
Since a < 0, the denominator [tex](1 - (h/2)a)[/tex] is always positive, and the numerator [tex](1 + (h/2)a)[/tex] is always less than or equal to 1. Therefore, the solution yn+1 is always less than or equal to yn, which means that the solution is stable for a < 0.

An athletic field is a 44yd-by-88yd rectangle, with a semicircle at each of the short sides. A running track 10 yd wide surrounds the field. If the track is divided into eight lanes of equal width, with lane 1 being the inner-most and lane 8 being the outer-most lane, what is the distance around the track along the inside edge of each lane?
The distance around the track along the inside edge of each lane is 614.44 yd for lane 1, 634.88 yd for lane 2, 655.32 yd for lane 3, 675.76 yd for lane 4, 696.20 yd for lane 5, 716.64 yd for lane 6, 737.08 yd for lane 7 and 757.52 yd for lane 8.
The distance around the track along the inside edge of each lane can be calculated using the following formula:
Distance = (2 × 44 yd) + (2 × π × radius)
where the radius is equal to 44 yd + (lane number × 10 yd).
For lane 1, the radius is equal to 44 yd + (1 × 10 yd) = 54 yd. Therefore, the distance around the track along the inside edge of lane 1 is (2 × 44 yd) + (2 × π × 54 yd) = 614.44 yd.
The same calculation can be done for the other lanes, with the radius increasing by 10 yd for each lane. The radius for lane 2 is 64 yd, for lane 3 is 74 yd, for lane 4 is 84 yd, for lane 5 is 94 yd, for lane 6 is 104 yd, for lane 7 is 114 yd and for lane 8 is 124 yd.

A person tosses a coin 9 times. In how many ways can he get 6 heads?
If a person tosses a coin 9 times, there are 84 ways in which a person can get 6 heads in 9 coin tosses.
When a person tosses a coin 9 times, there are two possible outcomes for each toss - either heads or tails. Hence, there are a total of 2^9 = 512 possible outcomes for 9 coin tosses.
To find the number of ways in which a person can get 6 heads, we need to consider the number of ways in which 6 heads can occur in the 9 coin tosses, while the remaining 3 tosses can result in tails. The number of ways in which 6 heads can occur in 9 tosses is given by the binomial coefficient C(9,6), which is equal to 84.
Hence, there are 84 ways in which a person can get 6 heads in 9 coin tosses. This can be calculated using the formula for binomial coefficients:
C(9,6) = 9!/(6!3!) = (987)/(321) = 84
Alternatively, we can also calculate this using a combination of multiplication and addition. We can choose any 6 out of the 9 coin tosses to result in heads, which can be done in C(9,6) ways.
For each of these ways, the remaining 3 coin tosses will result in tails, which can occur in only one way. Hence, the total number of ways in which a person can get 6 heads in 9 coin tosses is given by:
Number of ways = C(9,6) * 1 = 84 * 1 = 84

Mathematical formulas frequently employ same variable word to guarantee agreement between two claims. Many academic numbers are shown to be equal using mathematical expression, also known as assertions. In this case, the normalise method adds b + 6 to employ the example of y + 6 rather than splitting 12 into two parts. It is possible to determine the length of the line and the quantity of connections between each sign's constituents. The significance of a symbol usually contradicts itself.
Here,
The first plant cranks out 8x + 15 items every day, while the second cranks out 3x - 7 items every day. By deducting the daily output of the second plant from the daily output of the first plant, we can determine how many more items the first plant creates than the second plant:
=> (8x + 15) - (3x - 7) (3x - 7)
If we condense this phrase, we get:

The region is a triangle with vertices at (0, 4), (1, 5), and (5, 0).
To find the area of the triangle, we can use the formula for the area of a triangle:
Area = (1/2) * base * height
The base of the triangle is the distance between the points (0, 4) and (5, 0), which is 5.
The height of the triangle is the distance between the point (1, 5) and the line 5 = x + y. We can find the equation of the line perpendicular to 5 = x + y and passing through (1, 5). This line has a slope of 1 and passes through (1, 5), so its equation is y = x + 4. We can find the intersection of this line and the line 5 = x + y by solving the system of equations:
y = x + 4
y = 5 - x
Substituting y = x + 4 into the second equation, we get:
x + 4 = 5 - x
Solving for x, we get:

Answer:
We can substitute m = 2.5 and n = 5 into the expression:
m + (7*9)/n = 2.5 + (7*9)/5
We can simplify the second term:
(7*9)/5 = 63/5
Substituting back into the expression:
m + (7*9)/n = 2.5 + 63/5
We can find a common denominator and add the terms:
2.5 + 63/5 = 12.5/5 + 63/5 = 75/5 = 15

Answer:
Step-by-step explanation:
To find this answer you need to find the vertex of the parabola. Do this by using the formulas for h and k as follows:
[tex]h=\frac{-b}{a}[/tex] and [tex]k=c-\frac{b^2}{4a}[/tex], where a, b, and c come from the quadratic equation.
Filling in for h:
[tex]h=\frac{10}{2(.2)}=25[/tex]
Filling in for k:
[tex]k=650-\frac{100}{4(.2)} =525[/tex]
Thus, the coordinates for the vertex are (25, 525). The h value interprets the number of bowls that should be produced to minimize the cost of production (25) and the minimum production cost is the k value (525).

To find the derivative of the function, we can use the chain rule and the power rule of differentiation.
What is chain rule?
The chain rule is a formula used to find the derivative of a composite function. If y = f(g(x)), then as per chain rule the instantaneous rate of change of function ‘f’ relative to ‘g’ and ‘g’ relative to x results in an instantaneous rate of change of ‘f’ with respect to ‘x’
Let u = x² - 3, then we can rewrite the function as:
f(x) = [tex](u^{7})^\frac{1}{2}[/tex]
Using the chain rule and the power rule, we have:
f'(x) = (1/2) x (u^7)^(-1/2) x 7u^6 x 2x
Simplifying this expression, we get:
f'(x) = 7x(u^6) / (2(u^7)^(1/2))
Now, we can substitute x = -2 into this expression to find f'(-2):
f'(-2) = 7(-2)((-2)^2 - 3)^6 / (2(((-2)^2 - 3)^7)^(1/2))
Simplifying this expression, we get:
f'(-2) = -168/(2sqrt(19)^7) = -12.77 (rounded to two decimal places)
Therefore, f'(-2) = -12.77.

the answer is (A) 21-1/2.
Step-by-step explanation:
First, we need to calculate the rate of descent in feet per mile:
750 ft / 3 miles = 250 ft/mile
Next, we can set up a proportion to solve for the distance traveled:
(distance traveled) / (total altitude change) = (distance traveled) / (altitude change due to descent) + (altitude at which descent begins)
Let m be the distance traveled:
m / (32000 ft - 16000 ft) = m / (250 ft/mile * x miles) + 16000 ft
where x is the number of miles traveled when the pilot is 16000 ft above the ground.
Simplifying:
m / 16000 ft = m / (250 ft/mile * x miles) + 1
Multiplying both sides by 16000 ft:
m = m / (250 ft/mile * x miles) * 16000 ft + 16000 ft * 16000 ft
Multiplying both sides by (250 ft/mile * x miles):
m * (250 ft/mile * x miles) = m * 16000 ft + 16000 ft * (250 ft/mile * x miles)
Simplifying:
250 * x * m = 16000 * m + 4000 * x * m
Dividing both sides by m:
250 * x = 16000 + 4000 * x
Subtracting 4000 * x from both sides:
-3750 * x = -16000
Dividing both sides by -3750:
x = 4.266666... miles
Rounding to the nearest half mile gives us:
x ≈ 4.5 miles
Therefore, the answer is (A) 21-1/2.
what is the fraction of players on the field that are midfielders
a soccer team has 11 players on the fields . of those players , 2 are forwards , 4 are midfeilders, 4 are defenders , and 1 is a goalie
After addressing the issue at hand, we can state that As a result, decimal midfielders make up around 36.36% of the players on the pitch
what is decimal?The decimal number system is frequently used to express both integer and non-integer quantities. Non-integer values have been added to the Hindu-Arabic numeral system. The technique used to represent numbers in the decimal system is known as decimal notation. A decimal number consists of both a whole number and a fractional number. The numerical value of complete and partially whole amounts is expressed using decimal numbers, which are in between integers. The full number and the fractional part of a decimal number are separated by a decimal point. The decimal point is the little dot that appears between whole numbers and fractions. An example of a decimal number is 25.5. In this case, 25 is the total number, and 5 is the minimum.
The following formula can be used to determine the percentage of midfielders on the field:
Overall number of players on the field / Total number of midfielders
In this situation, the total number of midfielders is 4, and the total number of players on the pitch is 11.
As a result, the percentage of midfielders on the field is:
4 / 11
This can be expressed in decimal or percentage form as follows:
0.3636 (rounded to four decimal places) (rounded to four decimal places)
36.36% (rounded to two decimal places) (rounded to two decimal places)
As a result, midfielders make up around 36.36% of the players on the pitch.

i put $1000 in an account from high school graduation gifts, and $2000 into the same account after my college graduation 4 years later. five years after i started my first job how much is in the account if it earns 4% per year?
By using the concept of compound interest, the total amount is $4063.27.
We have,
The amount that was deposited during high school graduation = $1000
The amount that was deposited during college graduation after 4 years = $2000
The total number of years elapsed = 5 years
The interest rate per annum (p.a.) = 4%
The simple Interest (SI) formula is given by,
SI = P × r × t
where, P = Principal amount
r = Rate of interest
t = Time period
Compound Interest (CI) formula is given by,
CI = P (1 + (r/n))^(nt)
Where P = Principal amount
r = Rate of interest
t = Time period
n = Number of times interest is compounded
For the total amount using compound interest.
Total amount (A) = Principal + Compound interest
A = P + CI
Implying it to our data, we get the following.
For $1000 that was deposited during high school graduation,
For 5 years, n = 1, t = 5 years, r = 4% p.a.
CI = 1000[1+(4/100)]^(1×5)
CI = 1000[1+(1/25)]^5
CI = 1000×(26/25)^5
CI = 1000×1.21665
CI = $1216.65
For $2000 that was deposited during college graduation after 4 years,
The total number of years elapsed = 5 years + 4 years = 9 years
n = 1, t = 9 years, r = 4% p.a.
CI = 2000[1+(4/100)]^(1×9)
CI = 2000[1+(1/25)]^9
CI = 2000×(26/25)^9
CI = 2000×1.4233
CI = $2846.62
Therefore, the total amount (A) is $1216.65 + $2846.62 ⇒ $4063.27.

Patricio deposit $500 in a savings account theat pays 1. 5% simple interest. He does not withdraw any money from the account, and he makes no other deposit. How much money does Patricio have in the savings account after 5 years? The formula for simple interest is I=prt
According to simple interest, Patricio will have $537.50 in his savings account after 5 years.
To calculate the amount of money Patricio will have in his savings account after 5 years, we can use the formula for simple interest, which is I = prt. "I" stands for the amount of interest earned, "p" stands for the principal amount deposited, "r" stands for the interest rate per year (as a decimal), and "t" stands for the time period in years.
In this case, the principal amount (p) is $500, the interest rate (r) is 1.5% or 0.015 as a decimal, and the time period (t) is 5 years. Using the formula I = prt, we can calculate the amount of interest earned over 5 years:
I = prt
I = $500 x 0.015 x 5
I = $37.50
So, Patricio will earn $37.50 in simple interest over 5 years. To find out the total amount of money he will have in his savings account after 5 years, we simply add the interest earned to the principal amount:
Total amount = Principal amount + Interest earned
Total amount = $500 + $37.50
Total amount = $537.50
