<h3>Answer: f^{-1}(x) = -6+\sqrt[3]{x}</h3>

======================================================

Explanation:

Replace f(x) with y.

Swap x and y, then solve for y to get the inverse.

f(x) = (x+6)^3\\\\y = (x+6)^3\\\\x = (y+6)^3\\\\\sqrt[3]{x} = y+6\\\\y = -6+\sqrt[3]{x}\\\\f^{-1}(x) = -6+\sqrt[3]{x}\\\\

To solve for y, I first applied the cube root to both sides. Then I subtracted 6 from both sides.

When a negative number multiplies a negative number, it becomes positive

since it is multiplication, just multiply across, you do not need same denominators

5/8 x 16/25 = 80/200

80/200 = 40/100 = 20/50 = 2/5

2/5 is your answer

hope this helps

In a clothing store, 65% of the customers buy a shirt, 30% of the customers
diamong [38]

Answer:

75%

Step-by-step explanation:

List out known probabilities

\Pr(shirt) = 0.65 = \frac{65}{100} = \frac{13}{20}\\ \Pr(pants) = 0.40 = \frac{30}{100} = \frac{6}{20}\\\Pr(shirt \cap pants) = 0.20 = \frac{20}{100}=\frac{1}{5}

recall equation

\Pr(A \cup B)=\Pr(A)+\Pr(B)-\Pr(A \cap B)

Plug in values

\Pr(shirt \cup pants)=\frac{13}{20}+\frac{6}{20}-\frac{1}{5}\\\\therefore \Pr(shirt \cup pants) = \frac{15}{20} =\frac{3}{4} = 75\%

[NEED THIS ANSWERED QUICKLY]<br> What is the surface area of the triangular prism?
pochemuha

<u>Given</u>:

The base of the triangle is b = 3 feet.

The height of the triangle is h = 4 feet.

The other side of the triangle is 5 feet.

The height of the triangular prism is 20 feet.

We need to determine the surface area of the triangular prism.

<u>Surface area of the triangular prism:</u>

The surface area of the triangular prism is given by the formula,

SA=bh+(s_1+s_2+s_3)H

where b is the base of the triangle,

h is the height of the triangle,

s₁ , s₂ and s₃ are the sides of the triangle and

H is the height of the triangular prism.

Substituting the values, we get;

SA=(3)(4)+(3+4+5)(20)

SA=12+(12)(20)

SA=12+240

SA=252 \ ft^2

Thus, the surface area of the triangular prism is 252 ft²

andrew11 [14]

Answer:

"None of the answers are correct."

Step-by-step explanation:
