Answer:
D
Step-by-step explanation:
The interest is compounded annually, which means that interest from the previous year earns you even more money next year.
It should be obvious that after one year Alexis will have
$475 + $475 * 1.25% = $475 * 100% + $475 * 1.25% =
= 101.25% * $475 = 1.0125 * $475
Then, next year she would have
1.0125 * $475 + (1.0125 * $475) * 1.25% =
= (1.0125 * $475) * 1.0125 = 1.0125^2 * $475
See the pattern?
Alexis will have $475 * 1.0125^x after x years.
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:

9a.m is 9 hours since midnight.
This means that
x = 9
So, we have:

Evaluate

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
