Question 5

Jack planted a mysterious bean just outside his kitchen window. It immediately sprouted 2.56 cm above the ground. Jack kept a careful log of the plant’s growth. He measured the height of the plant each day at 8:00 A.M. and recorded these data. Write an exponential equation for this pattern. (should look like y=something use * for multiplication and ^ for exponents)

Accepted Answer

2.56*2.5^x

Question 6

$$8^x=4$$ use same base theorem to solve for x (write your answer as x=something)

Accepted Answer

x=2/3

Question 7

Accepted Answer

$$x^{\frac{2}{5}}$$

Answer

$$x^{\frac{5}{2}}$$

Question 8

solve for x, write your answer as a decimal rounded to two places $$\frac{1}{\sqrt{x}}=0.55$$ (answer: x=something)

Accepted Answer

x=3.31

Question 9

What is the equation for the inverse of $$f(x) = 1.8x +32$$?

Accepted Answer
