What is the Pythagorean Theorem?The Pythagorean Theorem states that in a right-angled triangle, the square of the length of the hypotenuse (the longest side) is equal to the sum of the squares of the lengths of the other two sides.
The theorem is expressed as follows:
c² = a² + b².
In which:
c is the length of the hypotenuse.a and b are the lengths of the other two sides (the legs) of the right-angled triangle.The diagonal length of the rectangle is the hypotenuse of a right triangle of sides 6 and 8, hence:
d² = 6² + 8²
d² = 100
d = 10.
The segments x and y are each half the length of the diagonal, and the two diagonals have the same length for a rectangle, hence:
x = y = 5.

a bowl contains three red and four yellow marbles. you randomly select two marbles from the bowl. which of the following is a conditional probability? assume the second marble is drawn from the marbles remaining after the first draw.
Answers
The conditional probability in this scenario is the probability of drawing a yellow marble on the second draw, given that the first marble drawn was red.
To calculate this conditional probability, we can use Bayes' theorem, which states that the probability of an event (in this case, drawing a yellow marble on the second draw) given some prior knowledge (in this case, that the first marble drawn was red) is equal to the probability of both events occurring (drawing a red marble first and a yellow marble second) divided by the probability of the prior event (drawing a red marble first).
The probability of drawing a red marble first is 3/7 since there are three red marbles out of a total of seven marbles in the bowl. Once a red marble is drawn, there are six marbles remaining, of which three are yellow. Therefore, the probability of drawing a yellow marble second, given that the first marble was red, is 3/6 or 1/2.
Putting this together, we can calculate the conditional probability as follows:
P(Yellow on Second Draw | Red on First Draw) = P(Red on First Draw and Yellow on Second Draw) / P(Red on First Draw)
= (3/7) * (3/6) / (3/7)
= 1/2
Therefore, the conditional probability in this scenario is 1/2 or 50%. This means that there is a 50% chance of drawing a yellow marble on the second draw, given that the first marble drawn was red.

Show that the functions f(x) = x, g(x) = x - 1, and h(x) = x + 3 are linearly dependent. Show, however, that f(x) = x2, g(x) = x - 1, and h(x) = x + 3 are linearly independent
Answers
To show that the functions f(x) = x, g(x) = x - 1, and h(x) = x + 3 are linearly dependent, we need to find a non-zero linear combination of the three functions that equals zero.
Let's assume that a, b, and c are constants such that:
a*f(x) + b*g(x) + c*h(x) = 0
Substituting in the given functions, we get:
a*x + b*(x - 1) + c*(x + 3) = 0
Simplifying this equation, we get:
(a + b + c) * x + (-b + 3c) = 0
For this equation to hold true for all x, we must have:
a + b + c = 0
-b + 3c = 0
This is a system of two equations with three unknowns, which means that we have infinitely many solutions. For example, we could choose a = 1, b = -2, and c = 1, and the equation would hold true. Therefore, we have shown that the functions f(x) = x, g(x) = x - 1, and h(x) = x + 3 are linearly dependent.
Now, let's show that the functions f(x) = x^2, g(x) = x - 1, and h(x) = x + 3 are linearly independent.
We need to show that there are no non-zero constants a, b, and c such that:
a*f(x) + b*g(x) + c*h(x) = 0
Substituting in the given functions, we get:
a*x^2 + b*(x - 1) + c*(x + 3) = 0
This equation holds true for all x if and only if its coefficients are all zero. Therefore, we need to solve the system of three equations:
a = 0
-b + c = 0
3c = 0
The first equation tells us that a must be zero. The third equation tells us that c must be zero. Substituting c = 0 into the second equation, we get:
-b = 0
Therefore, we must have b = 0 as well.
Since a, b, and c are all zero, we have shown that the functions f(x) = x^2, g(x) = x - 1, and h(x) = x + 3 are linearly independent.

suppose there is a lottery where the organizers pick a set of 11 distinct numbers. a player then picks 7 distinct numbers and wins when all 7 are in the set chosen by the organizers. numbers chosen by both the players and organizers come from the set {1, 2, ..., 80}. (a) let the sample space, s, be all the sets of 7 numbers the player can choose. what is |s|? (b) let e be the event that all the numbers the player chooses are in the winning set. what is |e|? (c) what is the probability of winning? as a reminder, you may leave your answer un- simplified.
Answers
(a) 40,475,358.
(b) 330
(c) 0.0008%.
(a) To find |S|, the total number of sets of 7 distinct numbers a player can choose, we need to find the combinations of choosing 7 numbers from the 80 available options. This can be calculated using the combination formula:
C(n, k) = n! / (k! * (n - k)!)
In this case, n = 80 (total numbers) and k = 7 (numbers to choose). So, |S| = C(80, 7):
|S| = 80! / (7! * (80 - 7)!)
|S| = 80! / (7! * 73!)
(b) To find |E|, the number of sets where all 7 numbers chosen by the player are in the winning set of 11 numbers chosen by the organizers, we need to find the combinations of choosing 7 numbers from the 11 available options in the winning set:
|E| = C(11, 7)
|E| = 11! / (7! * (11 - 7)!)
|E| = 11! / (7! * 4!)
(c) To find the probability of winning, we need to calculate the ratio of the favorable outcomes (|E|) to the total possible outcomes (|S|):
P(winning) = |E| / |S|
P(winning) = (11! / (7! * 4!)) / (80! / (7! * 73!))

No current will flow between two charged bodies if they have the
same
A) resistance
B) charge
C) potential
D) charge/ potential ratio
Answers
Two bodies can have the same resistance or charge/potential ratio, but still have different potentials, resulting in the flow of current between them.
The correct answer is C) potential.
When two bodies have the same potential, it means that the electric potential difference between them is zero. In this case, no work is required to move a charge from one body to the other, because the potential energy of the charge is the same on both bodies.
Since current is defined as the flow of electric charge, if there is no potential difference between two bodies, there will be no force driving the charges to move from one body to the other. Hence, no current will flow between the two bodies.
It is important to note that having the same resistance or charge/ potential ratio does not necessarily mean that no current will flow between two bodies. Resistance refers to the opposition to the flow of current, and the charge/ potential ratio is the charge per unit of electric potential. Therefore, two bodies can have the same resistance or charge/potential ratio, but still have different potentials, resulting in the flow of current between them.

Answers
In this regression analysis, the letter b in the equation y = a + bx represents the estimate of the cost for an additional customer visit. This means that for every additional customer visit to the store, the expected increase in monthly total costs is $2.08, according to the regression model.
The letter x in the regression equation represents the observed customer visits for a given month. This means that the regression model is predicting the monthly total costs based on the number of customer visits in that month.
The R2 value of 0.8681 means that 86.81% of the total variance in the monthly total costs can be explained by the regression equation, which indicates a strong relationship between the number of customer visits and the total costs. This can help managers of Brewsky's make informed decisions about how to allocate resources and improve profitability.

Answers
The price when x = 12 is 80 dollars.
The elasticity of demand, according to the given conditions, when x = 12 is 0.0625
To compute the price, p, when x = 12, we plug in x = 12 into the demand function P = 5(x + 4) "4:
P = 5(12 + 4) "4
P = 80
So the price when x = 12 is 80 dollars.
To compute the rate of change of demand with respect to price, p, we use implicit differentiation. Differentiating both sides of the demand function P = 5(x + 4) "4 with respect to p, we get:
dP/dp = 5(dx/dp)
Solving for dx/dp, we get:
dx/dp = (dP/dp) / 5
We know that dP/dx = 5, since that is the coefficient of x in the demand function. So when x = 12, we have:
dP/dx = 5
dP/dp = (dP/dx)(dx/dp) = 5(dx/dp)
Substituting in dP/dp = -15 (since we want the rate of change of demand with respect to price, not quantity), we get:
-15 = 5(dx/dp)
dx/dp = -3
So the rate of change of demand with respect to price, when x = 12, is -3 thousand units per dollar.
To compute the elasticity of demand when x = 12, we use the formula:
Elasticity of Demand = (% change in quantity demanded) / (% change in price)
We can find the % change in quantity demanded by using the derivative of the demand function. We have:
P = 5(x + 4) "4
dP/dx = 5
dP/dx = 5(x + 4)"5(dx/dx) = 5(12 + 4)"5(dx/dx)
dx/dx = (dP/dx) / (5(x + 4)"5) = 1 / (x + 4)"5
So when x = 12, we have:
dx/dx = 1 / (12 + 4)"5 = 1/16
This means that a 1% increase in quantity demanded corresponds to a 1/16% increase in x. Similarly, a 1% decrease in quantity demanded corresponds to a 1/16% decrease in x.
To find the % change in price, we can use the fact that the demand function is:
P = 5(x + 4) "4
This means that a 1% increase in price corresponds to a 1% increase in P, since there are no other variables involved in the equation. Similarly, a 1% decrease in price corresponds to a 1% decrease in P.
So we have:
% change in quantity demanded = 1/16%
% change in price = 1%
Plugging these into the formula for elasticity of demand, we get:
Elasticity of Demand = (% change in quantity demanded) / (% change in price)
Elasticity of Demand = (1/16%) / (1%)
Elasticity of Demand = 1/16
So the elasticity of demand when x = 12 is 1/16 or 0.0625.

The square of a positive number is 42 more than the number itself. What is the number?
Answers
The number we're looking for is 7.
Let's call the number we're looking for "x". According to the problem, the square of the number is 42 more than the number itself. In equation form, this can be written as:
[tex]x^2[/tex] = x + 42
To solve for x, we want to get all the terms on one side of the equation. We can start by subtracting x + 42 from both sides:
[tex]x^2[/tex] - x - 42 = 0
Now we have a quadratic equation. We can solve it by factoring or by using the quadratic formula. Let's use factoring. We want to find two numbers that multiply to -42 and add up to -1 (since the coefficient of x is -1). One possible pair of numbers is -7 and 6, since -7 × 6 = -42 and -7 + 6 = -1. So we can rewrite the equation as:
(x - 7)(x + 6) = 0
This tells us that either x - 7 = 0 or x + 6 = 0. Solving for x in each case, we get:x = 7 or x = -6
We're looking for a positive number, so the solution is x = 7. Therefore, the number we're looking for is 7.

38. A new apartment complex with 90 one-bedroom apartment units and 100 two-bedroom apartment units was built near a lake. Rental prices that will provide full occupancy are estimated at $1200 for one-bedroom units and $1800 for two-bedroom units. A market survey suggests that for every $20 increase in the price of a one-bedroom unit one less customer will sign a lease and for every $60 increase in the price of a two-bedroom unit two less customers will sign a lease. What rental price should the manager charge to maximize revenue?
Answers
The required manager should charge $1600 for one-bedroom units and $2250 for two-bedroom units to maximize revenue.
Let x be the number of $20 increases in the price of a one-bedroom unit, and y be the number of $60 increases in the price of a two-bedroom unit. Then the rental prices for one-bedroom and two-bedroom units can be expressed as:
One-bedroom price = $1200 + $20x
Two-bedroom price = $1800 + $60y
The total number of customers for one-bedroom units is 90 minus the number of customers lost due to the price increase, which is x. Similarly, the total number of customers for two-bedroom units is 100 minus the number of customers lost due to the price increase, which is 2y. Therefore, the total revenue can be expressed as:
Revenue = (90 - x) * ($1200 + $20x) + (100 - 2y) * ($1800 + $60y)
Expanding and simplifying this expression, we get:
Revenue = 216000 + 9600x - 240x² + 180000 + 108000y - 7200y²
Collecting like terms, we get:
Revenue = -240x² - 7200y² + 9600x + 108000y + 396000
To find the rental price that maximizes revenue, we need to find the values of x and y that maximize the revenue. We can do this by taking partial derivatives of the revenue function with respect to x and y and setting them equal to zero:
dRevenue/dx = -480x + 9600 = 0
dRevenue/dy = -14400y + 108000 = 0
Solving for x and y, we get:
x = 20
y = 7.5
Therefore, the rental prices that maximize revenue are:
One-bedroom price = $1200 + $20x = $1600
Two-bedroom price = $1800 + $60y = $2250
So the manager should charge $1600 for one-bedroom units and $2250 for two-bedroom units to maximize revenue.

4 585.9375
Write an explicit rule for the geometric sequence
What is f(12)?
Answers
The common ratio is 1.25. An explicit rule for the geometric sequence is f(n) = 300(1.25)ⁿ⁻¹ . The value of f(12) is 5,722.05.
To find the common ratio of the sequence, we need to divide each term by the previous term. For example, to find the common ratio between the first two terms:
375/300 = 1.25
Similarly, we can find the common ratio between the second and third terms:
468.75/375 = 1.25
And the common ratio between the third and fourth terms:
585.9375/468.75 = 1.25
Since the common ratio is the same for each pair of adjacent terms, we can conclude that the explicit rule for the geometric sequence is:
f(n) = 300(1.25)ⁿ⁻¹
To find f(12), we can simply substitute 12 for n in the formula:
f(12) = 300(1.25)¹²⁻¹
f(12) = 300(1.25)¹¹
f(12) = 300(19.0735)
f(12) = 5,722.05
Therefore, f(12) is 5,722.05.

Find the slope for the line that passes through the points (-2,5) and (1,0)
Answers
Answer:
[tex]m=\frac{-5}{3}[/tex]
Step-by-step explanation:
Pre-SolvingWe want to find the slope between the points (-2,5) and (1,0).
The slope (m) can be found using the formula [tex]\frac{y_2-y_1}{x_2-x_1}[/tex], where [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] are points.
SolvingWe are already given the values of the points, but let's label their values to avoid any confusion and mistakes.
[tex]x_1=-2\\y_1=5\\x_2=1\\y_2=0[/tex]
Now, substitute into the formula.
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]m=\frac{0-5}{1--2}[/tex]
Simplify this to:
[tex]m=\frac{0-5}{1+2}[/tex]
[tex]m=\frac{-5}{3}[/tex]
The slope is -5/3.

Answers
The absolute minimum and absolute maximum values of the function f(x) = 3x^4 - 4x^3 - 36x^2 on the interval [-3, 5] are -283 and 81, respectively. To get the absolute minimum and absolute maximum values of the function f(x) = 3x^4 - 4x^3 - 36x^2 on the interval [-3, 5].
Step 1: Find the critical points by taking the derivative of the function and setting it equal to zero.
f'(x) = 12x^3 - 12x^2 - 72x
Step 2: Factor the derivative.
f'(x) = 12x(x^2 - x - 6)
Step 3: Solve for x to find the critical points.
x = 0, x = -1, x = 6
Step 4: Evaluate the function at the critical points and endpoints of the interval.
f(-3) = 81
f(0) = 0
f(-1) = 43
f(5) = -283
Step 5: Identify the absolute minimum and absolute maximum values.
The absolute minimum value of f(x) is -283 at x = 5.
The absolute maximum value of f(x) is 81 at x = -3.
So, the absolute minimum and absolute maximum values of the function f(x) = 3x^4 - 4x^3 - 36x^2 on the interval [-3, 5] are -283 and 81, respectively.
