Answer:

t=2

Step-by-step explanation:

log4(7t+2)=2

Raise each side to the base of 4

4^log4(7t+2)=4^2

The log goes away

7t+2 = 16

Subtract 2 from each side

7t+2-2 = 16-2

7t = 14

Divide each side by 7

7t/7 = 14/7

t = 2

1. Which function represents exponential decay?

MatroZZZ [7]

Answer:

y= 7^-t

Step-by-step explanation:

Equation for exponential decay:

An equation represents exponential decay if a term between 0 and 1 is elevated to the independent variable.

In this question:

First option 4 is elevated, so not exponential decay.

Second option:

$7^{-t} = \frac{1}{7^t} = (\frac{1}{7})^{t}$

$0 < \frac{1}{7} < 1$ , thus, the second option represents exponential decay.
