Find g[h(x)] and h[g(x)] of the functions g(x)=x^2-7 and h(x)=3x+2
Answer:
g(h(x)) = 9x² + 12x - 3
h(g(x)) = -3x² - 19
Step-by-step explanation:
g(h(x)) = (3x² + 2)² - 7
= 9x² + 6x + 6x + 4 - 7
= 9x² + 12x - 3
h(g(x)) = 3(x² - 7) + 2
= 3x² - 21 + 2
= 3x² - 19

Choose the three rectangles that have a perimeter of 12 meters.
Answer:
I think the answers would be a d and b
Step-by-step explanation:
the perimeter formula for a rectangle is 2L + 2W
if we take the measurements for rectangle a and add 4 + 4, we get 8. then we can do 2 + 2 to get 4. lastly, we would add 8 + 4, which equals 12.
for rectangle d, we can do 3 + 3, which equals 6. because the measurements are the same on each side, we don't have to do another equation and we would just add 6 + 6 to get 12.
and for rectangle b, you can do 1 + 1 = 2 and 5 + 5 = 10, then add 10 and 2 together to get 12.
I don't understand this: If Kelly spins the spinner 120 times, how many times would you predict the spinner lands on pink based on experimental data? Show your work in the box below the image.
Pink:6
purple:12
yellow:9
Blue:13
The expected value of the spinner landing on pink will be 18.
What is the expected value?The anticipated value is an extension of the weighting factor in statistical inference. Informally, the anticipated value is the simple average of a significant number of outcomes of a randomly selected variable that was separately chosen.
The expected value is given below.
E(x) = np
Where n is the number of samples and p is the probability.
If Kelly spins the spinner 120 times. The table is given below.
Color Frequency
Pink 6
Purple 12
Yellow 9
Blue 13
Total 40
Then the probability of the pink color will be
p = 6 / 40
p = 0.15
Then the expected value of the spinner landing on pink will be
E(x) = 120 x 0.15
E(x) = 18
The expected value of the spinner landing on pink will be 18.
More about the expected value link is given below.

At a high school, 18% of all students are in the school musical and the choir, and 32% of the students are in the school musical. What is the probability that a student is in the choir, given that the student is in the school musical
Answer: 56.25%
Step-by-step explanation:
Probability that student is in the school musical and choir = Probability that student is in choir given that they are in musical * Probability that student is in the school musical
Changing the subject of the formula:
Probability that student is in choir given that they are in musical = Probability that student is in the school musical and choir / Probability that student is in the school musical
= 18% / 32%
= 56.25%

please help me
Answer:
[tex]a^3 + b^3 = -4[/tex]
Step-by-step explanation:
Given
[tex]a + b = 3ab = 2[/tex]
Required
Solve: [tex]a^3 + b^3[/tex]
Rewrite the expression as:
[tex]a^3 + b^3 = a^3 - a^2b +ab^2 + a^2b - ab^2 + b^3[/tex]
Factorize
[tex]a^3 + b^3 = a(a^2 - ab +b^2) + b(a^2 - ab + b^2)[/tex]
[tex]a^3 + b^3 = (a + b)(a^2 - ab + b^2)[/tex]
Rewrite as:
[tex]a^3 + b^3 = (a + b)(a^2 + b^2- ab)[/tex]
[tex]a^3 + b^3 = (a + b)(a^2 + b^2+2ab - 3ab)[/tex]
Factorize
[tex]a^3 + b^3 = (a + b)((a + b)^2 - 3ab)[/tex]
Open brackets
[tex]a^3 + b^3 = (a + b)^3 - 3ab(a + b)[/tex]
Given that:
[tex]a + b = 3ab = 2[/tex]
This means that:
[tex]a + b = 2[/tex] and [tex]3ab = 2[/tex]
So, we have:
[tex]a^3 + b^3 = (a + b)^3 - 3ab(a + b)[/tex]
[tex]a^3 + b^3 = 2^3 - 3 * 2 * 2[/tex]
[tex]a^3 + b^3 = 8 - 12[/tex]
[tex]a^3 + b^3 = -4[/tex]

Out of a random sample of 330 apples, 25 are rated "AAA." Estimate the number of apples that would be rated "AAA" in a crop of 50,000 apples.
Answer:
3750 apples
Step-by-step explanation:
Prob (Apple AAA rating) = AAA rated apples / Total Apples
25 / 330 = 0.075
Expected apples rated AAA from 50000 apples = P(AAA rating) x Apples no.
0.075 x 50000

The polynomial V(x)=x^2+9x^2-16x-144 represents volume of a shipping crate. Explain how to find the area of the base of the crate? if the polynomial H(x)=x+4 represents the height of the crate
Answer:
x = − 9 , − 4 , 4
Step-by-step explanation:
Each crate is in the shape of a rectangular solid. Its dimensions are length, width, and height. The rectangular solid shown in the image below has a length
4 units, width 2 units, and height 3
units. Can you tell how many cubic units there are altogether? Let’s look layer by layer.
Breaking a rectangular solid into layers makes it easier to visualize the number of cubic units it contains. This
4 by 2 by 3 rectangular solid has 24 cubic units.
A rectangular solid is shown. Each layer is composed of 8 cubes, measuring 2 by 4. The top layer is pink. The middle layer is orange. The bottom layer is green. Beside this is an image of the top layer that says
Altogether there are 24 cubic units. Notice that 24 is the length × width × height.
The top line says V equals L times W times H. Beneath the V is 24, beneath the equal sign is another equal sign, beneath the L is a 4, beneath the W is a 2, beneath the H is a 3.
The volume, V, of any rectangular solid is the product of the length, width, and height.
V = L W H
We could also write the formula for the volume of a rectangular solid in terms of the area of the base. The area of the base, B, is equal to length × width. B = L ⋅ W
We can substitute
B for L ⋅ W in the volume, formula to get another form of the volume formula.
The top line says V equals red L times red W times H. Below this is V equals red parentheses L times W times H. Below this is V equals red capital B times h.
We now have another version of the volume formula for rectangular solids. Let’s see how this works with the
4 × 2 × 3
Besides the solid is V equals Bh. Below this is V equals Base times height. Below Base is parentheses 4 times 2. The next line says V equals parentheses 4 times 2 times 3. Below that is V equals 8 times 3, then V equals 24 cubic units.

find the area of the trapozoid.
Answer:40
Step-by-step explanation:To find the area of a trapzoid first add base a to base b then multiply the height then after divide the product by 2 the answer is 40 because the height for the trapzoid is 5 and for base 1 is 6 also base 2 is 10.First add 10+6=16 then muitiply 16x5=80 divide 80 with 2 will give you 40.
plsssss helpñ i would appreciate it!!!
can someone please help me coz i really need this :(
i need serious answer :(
Answer:
1. DB = 10 as diagonals of isosceles trapezoid are congruent
2. ∠DAB and ∠BCD are supplementary angles
m∠BCD = 180° - 120° = 60°3. ∠BCD is congruent with ∠ADC as trapezoid is isosceles
m∠BCD = m ∠ADC = 65°4. AB = 15, DC = 25,
EB = 1/2(AB + DC) as midlineEB = 1/2(15 + 25) = 205. m∠ADC = 2x - 10, m∠ABC = 3x + 40
These are supplementary, find x first:
2x - 10 + 3x + 40 = 1805x + 30 = 1805x = 150x = 30m∠BCD = m∠ADC = 2*30 - 10 = 50°is -2 more than -1? or is it the other way around

Answer:
Step-by-step explanation:
The question requires you to substitute x=5 into the expression, 3x-2.
The expression, therefore becomes:
