Answer:

f(x) = -1/2·10^x

Step-by-step explanation:

The y-intercept is -1/2.

The common ratio is (-1/20)/(-1/200) = 10, so the exponential function can be written as ...

f(x) = -1/2·10^x

The temperature, t, in degrees celsius, in a warehouse changes according to the function t(h) = 18 + 4sin(pi/12 (x = 8)).

egoroff_w [7]

The rate at which the temperature is changing at 9 a.m. is 19.03 degrees Celsius per hour

<h3>How to determine the rate at 9a.m?</h3>

The function is given as:

$t(h) = 18 + 4\sin(\pi/12(x - 8))$

9a.m is 9 hours since midnight.

This means that

x = 9

So, we have:

$t(h) = 18 + 4\sin(\pi/12(9 - 8))$

Evaluate

$t(h) = 18 + 4\sin(0.262)$

Evaluate the expression

t(h) = 19.03

Hence, the rate at which the temperature is changing at 9 a.m. is 19.03 degrees Celsius per hour
