How does h(t) = 9^t change over the interval from t = 0 to t = 1? Choices: (A)h(t) decreases by 9 (B)h(t) increases by 800% (C)h(t) increases by 900% (D)h(t) increases by 9%

Calculate h(0): Calculate h(0) by substituting t = 0 into h(t) = 9^t. h(0) = 9^0 h(0) = 1Calculate h(1): Calculate h(1) by substituting t = 1 into h(t) = 9^t. h(1) = 9^1 h(1) = 9Determine increase or decrease: Determine if h(t) increases or decreases from t = 0 to t = 1. Since h(0) = 1 and h(1) = 9, h(t) increases.Calculate percentage increase: Calculate the percentage increase from t = 0 to t = 1. % increase = [(h(1) - h(0)) / h(0)] * 100% % increase = [(9 - 1) / 1] * 100% % increase = [8 / 1] * 100% % increase = 8 * 100% % increase = 800%

Q. How does

h(t) = 9^t

change over the interval from

t = 0

t = 1

\newline

Choices:

\newline

(A)

h(t)

decreases by

9

\newline

(B)

h(t)

increases by

800\%

\newline

(C)

h(t)

increases by

900\%

\newline

(D)

h(t)

increases by

t = 0

0

Calculate $h(0)$ : Calculate $h(0)$ by substituting $t = 0$ into $h(t) = 9^t$ . $\newline$ $h(0) = 9^0$ $\newline$ $h(0) = 1$
Calculate $h(1)$ : Calculate $h(1)$ by substituting $t = 1$ into $h(t) = 9^t$ . $\newline$ $h(1) = 9^1$ $\newline$ $h(1) = 9$
Determine increase or decrease: Determine if $h(t)$ increases or decreases from $t = 0$ to $t = 1$ . Since $h(0) = 1$ and $h(1) = 9$ , $h(t)$ increases.
Calculate percentage increase: Calculate the percentage increase from $t = 0$ to $t = 1$ .
% increase = $\left[\frac{h(1) - h(0)}{h(0)}\right] \times 100\%$
% increase = $\left[\frac{9 - 1}{1}\right] \times 100\%$
% increase = $\left[\frac{8}{1}\right] \times 100\%$
% increase = $8 \times 100\%$
% increase = $800\%$
