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

The answer is 4,000 ft squared because since the sides are 100 ft and 80ft then we need to multiply them which is 8,000 then divide that by 2 since it’s a triangle which is 4,000 ft squared.
