Choose the correct item from each drop-down menu to factor the trinomial 3x2 + 13x – 10 by grouping
The factored form of 3x^2 + 13x - 10 is (3x - 2)(x + 5).
To factor 3x^2 + 13x – 10 by grouping, we need to find two numbers whose product is 3(-10) = -30 and whose sum is 13.
Let's list all the factor pairs of -30:
-1, 30
-2, 15
-3, 10
-5, 6
Out of these pairs, the pair that adds up to 13 is -2 and 15.
We can use these numbers to rewrite the middle term:
3x^2 - 2x + 15x - 10
Now, we can group the first two terms and the last two terms:
(3x^2 - 2x) + (15x - 10)
We can factor out the greatest common factor from each group:
x(3x - 2) + 5(3x - 2)
Now, we can see that we have a common factor of (3x - 2):
(3x - 2)(x + 5)

Every year, Johnathan the lumberjack cuts down all the trees on his farm. He finds that %60 of the trees die, but the rest grow again from the stumps that remain. What percent of the original trees are still alive after 3 years?
After answering the presented question, we can conclude that As a equation result, approximately 44.4% of the original trees are still living after three years.
What is equation?An equation is a mathematical statement that proves the equality of two expressions connected by the equal symbol '='. 2x - 5 Equals 13, for example. Expressions include 2x-5 and 13. The character '=' joins the two expressions. A mathematical formula with two algebraic expressions on either side of an equal sign (=) is known as an equation. It demonstrates the relationship of equivalence between the left and right formulas. In every formula, LHS = RHS (left side = right side).
Assuming that all of the trees on the farm are cut down each year, the percentage of trees that survive after three years is as follows:
60% of the trees die after the first year, leaving only 40% of the original trees.
Following the first year, 40% of the original trees are still standing.
Following the second year, 40% of the original trees remain + (40% of the original trees * 100% - 60% = 40% stump growth) = 64% of the original trees remain.
Following the third year, 40% of the original trees remain + (64% of the original trees * 100% - 60% = 4.4% stump growth) = 44.4% of the original trees remain.
As a result, approximately 44.4% of the original trees are still living after three years.

The value of x which would make GHJK a rhombus would be 42 degrees.
Nora can construct a kite with diagonals that bisect each other if the kite is in the shape of a rhombus.
How to find the value of x ?The way that a Rhombus is drawn is such that ∠ GKJ and ∠ HGK would add up to 180 degrees. If these angles are bisected as shown, then the corresponding angles would add up to 90 degrees as a result.
If this shape is to be a rhombus then the value of x would be :
= 90 - 48
= 42 degrees
What kind of kite has diagonals that bisect ?A kite is a quadrilateral with two pairs of adjacent congruent sides. The diagonals of a kite intersect at a right angle, but they do not necessarily bisect each other.
If the diagonals of a kite bisect each other, it means that they cut each other into two equal parts. This can only happen if the kite is a rhombus, which is a special type of kite where all four sides are congruent.
Therefore, if Nora wants to construct a kite with diagonals that bisect each other, she would need to ensure that the kite is a rhombus.

A rectangular fish tank has a width w inches, length w+ 8 inches, and height 18 - w inches. All dimensions are greater than 6 inches. The volume of the tank is 1440 cubic inches. How many inches is the height of the fish tank?
As per the volume, the height of the fish tank is 0.4 inches.
First, we are given that the width of the tank is w inches, the length is w+8 inches, and the height is 18-w inches. We also know that all dimensions are greater than 6 inches. Using the formula for the volume of a rectangular prism, we can write:
V = lwh
Substituting the given values, we get:
1440 = (w+8)(w)(18-w)
Now, we can simplify this equation by expanding the product on the right-hand side:
1440 = 18w² + 8w(18-w)
Simplifying further, we get:
1440 = 18w² + 144w - 8w²
Combining like terms, we get:
10w² + 144w - 1440 = 0
Dividing both sides by 10, we get:
w² + 14.4w - 144 = 0
Now we can solve for w using the quadratic formula:
w = (-b ± √(b² - 4ac)) / 2a
where a = 1, b = 14.4, and c = -144. Plugging in these values, we get:
w = (-14.4 ± √(14.4² - 4(1)(-144))) / 2(1)
Simplifying, we get:
w = (-14.4 ± √(432.16)) / 2
w = (-14.4 ± 20.8) / 2
w = -17.6 or w = 3.6
Since we know that all dimensions are greater than 6 inches, we can eliminate the negative solution and conclude that w = 3.6 inches is not valid. Therefore, the width of the tank is w = 17.6 inches.
Now we can use this value to find the height of the tank. Substituting w = 17.6 into the expression for the height, we get:
h = 18 - w
h = 18 - 17.6
h = 0.4
Therefore, the height of the tank is h = 0.4 inches, or equivalently, 4/10 of an inch.

how to algebraically find all the real zeros on a polynomial function
Answer:
To find all the real zeros of a polynomial function algebraically, use the Rational Root Theorem to generate a list of possible rational zeros and use synthetic division to test each possible zero. The zeros that remain after testing all the possible zeros are the real zeros of the polynomial function.
To find all the real zeros of a polynomial function algebraically, you can use the Rational Root Theorem and synthetic division. The Rational Root Theorem states that if a polynomial function has integer coefficients, then any rational zero (i.e., a zero that can be expressed as a fraction) must have a numerator that is a factor of the constant term and a denominator that is a factor of the leading coefficient.
Here are the steps you can follow:
1. Write the polynomial function in descending order of degree, with all like terms combined.
2. Use the Rational Root Theorem to generate a list of possible rational zeros. This list will be a set of all the possible fractions that can be formed by dividing a factor of the constant term by a factor of the leading coefficient.
3. Use synthetic division to test each possible zero. Start with the smallest possible denominator and work your way up. If a possible zero is not a zero of the polynomial function, cross it off the list.
4. Repeat step 3 until all the possible zeros have been tested. The zeros that remain are the real zeros of the polynomial function.
For example, let's say we have the polynomial function f(x) = x^3 - 6x^2 + 11x - 6.
Write the polynomial function in descending order of degree: f(x) = x^3 - 6x^2 + 11x - 6.
Use the Rational Root Theorem to generate a list of possible rational zeros: ±1, ±2, ±3, ±6.
Use synthetic division to test each possible zero. We start with x = 1:
1 │ 1 -6 11 -6
│ 1 -5 6
└─────────────
1 -5 6 0
Since the remainder is zero, we have found a zero of the polynomial function at x = 1. We can write the factorization f(x) = (x - 1)(x^2 - 5x + 6).
Now we use synthetic division to test the other possible zeros:
2 │ 1 -6 11 -6
│ 2 12 46
└─────────────
1 -4 23 40
x = 2 is not a zero of the polynomial function.
3 │ 1 -6 11 -6
│ 3 15 78
└─────────────
1 -3 26 72
x = 3 is not a zero of the polynomial function.
-1 │ 1 -6 11 -6
│ -1 7 -4
└────────────
1 -7 18 -10
x = -1 is not a zero of the polynomial function.
-2 │ 1 -6 11 -6
│ -2 16 -50
└────────────
1 -8 27 -56
x = -2 is not a zero of the polynomial function.
-3 │ 1 -6 11 -6

The length of human pregnancies is approximately normal with mean μ=266days and standard deviation σ=16days.
(a) What is the probability that a randomly selected pregnancy lasts less than 262 days?
(b) Suppose a random sample of 51 pregnancies is obtained. Describe the sampling distribution of the sample mean length of pregnancies.
(c) What is the probability that a random sample of 51 pregnancies has a mean gestation period of 262 days or less?
(d) What is the probability that a random sample of 106 pregnancies has a mean gestation period of 262 days or less?
The probability that a random sample of 106 pregnancies has a mean gestation period of 262 days or less is 0.00003.
What is probability?
Probability is a measure of the likelihood that an event will occur. It is a number between 0 and 1, where 0 represents an impossible event and 1 represents a certain event. Probabilities are usually expressed as fractions, decimals, or percentages.
(a) To find the probability that a randomly selected pregnancy lasts less than 262 days, we need to standardize the value using the formula z = (x - μ) / σ, where x is the value we're interested in, μ is the mean, and σ is the standard deviation.
z = (262 - 266) / 16 = -0.25
Using a standard normal distribution table or calculator, we find that the probability of getting a z-score of -0.25 or less is 0.4013. Therefore, the probability that a randomly selected pregnancy lasts less than 262 days is 0.4013.
(b) The sampling distribution of the sample mean length of pregnancies is approximately normal with mean μ = 266 and standard deviation σ = 16 / sqrt(51) = 2.2449. This is known as the central limit theorem.
Using a standard normal distribution table or calculator, we find that the probability of getting a z-score of -2.8304 or less is 0.0023. Therefore, the probability that a random sample of 51 pregnancies has a mean gestation period of 262 days or less is 0.0023.
(d) Using the same formula as in part (c), we have:
z = (262 - 266) / (16 / sqrt(106)) = -4.0077
Using a standard normal distribution table or calculator, we find that the probability of getting a z-score of -4.0077 or less is 0.00003.
Therefore, the probability that a random sample of 106 pregnancies has a mean gestation period of 262 days or less is 0.00003.

How many days can the baby drink the juice if no one else drinks more
The baby will drink 45 liters of milk in 30 days when baby drink 3 liters of milk in 2 days.
To solve this problem, we can set up a proportion using the fact that the amount of milk the baby drinks is directly proportional to the number of days:
milk consumed / number of days = constant
Let's call the constant of proportionality k. Then we can write:
3 liters / 2 days = k
To find the value of k, we can solve for it:
k = 3 liters / 2 days = 1.5 liters/day
Now we can use this value of k to find how much milk the baby will drink in 30 days:
milk consumed / 30 days = 1.5 liters/day
Multiplying both sides by 30, we get:
milk consumed = 1.5 liters/day x 30 days = 45 liters

[tex]4; 4 \times 1, 4 \times 2, 4 \times 3, 4 \times 4, 4 \times 5, 4 \times 6.\\4; 4, 8, 12, 16, 20, 24.[/tex]
An Example of the LCM:
[tex]4; 4, 8, 12, 16, 20, [24], 28\\6; 6, 12, 18, [24], 30, 36, 42. \\The \ LCM \ is \ 24.[/tex]
Let's use the example above as a guide, but for our values in the denominator.
[tex]2; 2, 4, [6], 8, 10, 12, 14.\\3; 3, [6], 9, 12, 15, 18, 21.\\The \ LCM \ is \ 6.[/tex]
Our Denominators will be 6.
Multiply both the Numerator and the Denominator by the number needed to make the denominator 6.
[tex]\frac{1 \times 3}{2 \times 3}=\frac{3}{6} \\\frac{1 \times 2}{3 \times 2} = \frac{2}{6}[/tex]
Add:
[tex]\frac{3}{6} + \frac{2}{6} = \frac{5}{6} \\[/tex]
Our final answer is [tex]\frac{5}{6} .[/tex]
Henry is planning a party for his daughter, Rebecca. The party has a beach theme. Henry plans to fill a sandbox with fresh sand so the kids can build sandcastles. The sandbox is twelve feet long and two feet tall. The width of the sandbox is half of its length. What is the volume of sand needed to fill the sandbox?
Answer:144 ft³
Step-by-step explanation:
The width of the sandbox is half of its length, so we can start by finding the length:
Length = 12 feet
Width = 1/2 * Length = 1/2 * 12 feet = 6 feet
Height = 2 feet
The volume of sand needed to fill the sandbox is the product of its length, width, and height:
Volume = Length * Width * Height
Volume = 12 feet * 6 feet * 2 feet
Volume = 144 cubic feet

Find the volume generated by rotating the region in the first quadrant bounded by y =e" and the X-axis from = 0 to x = ln(3) about the y-axis. Express your answer in exact form. Volume =
The volume generated by rotating the region in the first quadrant bounded by y = ex and the x-axis from x = 0 to x = ln(3) about the y-axis is (πln(3)3)/3.
To find the volume generated by rotating the region in the first quadrant bounded by y = ex and the x-axis from x = 0 to x = ln(3) about the y-axis, we can use the disk method. The disk method involves slicing the region into thin disks and adding up their volumes.
The volume of each disk is πr2h, where r is the radius of the disk and h is the thickness of the disk. In this case, the radius of each disk is x and the thickness is dx.
So, the volume of the region is:
V = ∫0ln(3)πx2dx
We can use the power rule for integration to solve this integral:
V = π∫0ln(3)x2dx = π[(x3)/3]0ln(3) = π[(ln(3)3)/3 - (03)/3] = (πln(3)3)/3
Therefore, the volume generated by rotating the region in the first quadrant bounded by y = ex and the x-axis from x = 0 to x = ln(3) about the y-axis is (πln(3)3)/3. This is the exact form of the volume.

Determine the equation of the tangent line to the given path at the specified value of t. (Enter your answer as a comma-separated list of equations in (x, y, z) coordinates.) (sin(3t), cos(3t), 2t^9/2)); t = 1
The equation of the tangent line to the given path at the specified value of t is (x - sin(3), 3cos(3)(y - cos(3)), -3sin(3)(z - 1), 9/2).
To determine the equation of the tangent line to the given path at the specified value of t, we need to find the derivative of the given path with respect to t. The derivative of the given path is (3cos(3t), -3sin(3t), 9t^8/2). Now, we can plug in the specified value of t = 1 to find the slope of the tangent line at that point. The slope of the tangent line at t = 1 is (3cos(3), -3sin(3), 9/2).
Next, we can find the point on the given path at t = 1 by plugging in the specified value of t into the original equation. The point on the given path at t = 1 is (sin(3), cos(3), 1).
Finally, we can use the point-slope form of an equation to find the equation of the tangent line. The equation of the tangent line in (x, y, z) coordinates is (x - sin(3)) = 3cos(3)(y - cos(3)) = -3sin(3)(z - 1) = 9/2.
Therefore, the equation of the tangent line to the given path at the specified value of t is (x - sin(3), 3cos(3)(y - cos(3)), -3sin(3)(z - 1), 9/2).

Please help me I tried I got a 60
Answer:
X = 90 , Y = 37 and Z = 53 Degrees.
Step-by-step explanation:
Z = 53 as opposite angles of a parallelogram are equal
Therefore, Z + Y + 90 = 180 ( Angle sum Property of a triangle)
= 53 + Y + 90 = 180
Y = 180 - 143
Y = 37
Now to find x , we know Y is the Alternate Interior angle of the angle adjacent to the 90*
Keeping that angle as "o"
Angle O = Angle Y by Alternate Interior Angle Therom
Therefore , Angle X + Angle O + 53 = 180 (ASP of triangle)
Angle X + 37 + 53 = 180
Angle X = 180 - 90
Angle X = 90*
In summary , X = 90 , Y = 37 and Z = 53.
Hope it helps.
Sam invests $500 for two years at an interest rate of 12%, compounded twice a year. How much will his total investment be worth after 2 years?
Answer:
The formula for compound interest is:
A = P(1 + r/n)^(nt)
Where:
A = the final amount
P = the principal (initial amount)
r = the annual interest rate (as a decimal)
n = the number of times the interest is compounded per year
t = the time the money is invested (in years)
In this case, P = $500, r = 0.12, n = 2 (compounded twice a year), and t = 2.
So, A = 500(1 + 0.12/2)^(2*2) = $673.01
Therefore, Sam's total investment will be worth $673.01 after 2 years.
