From the given exponential function, we have that:
- The initial amount is of 175.
- The growth rate is of 2.8%.
- When t = 5, we have that
.
<h3>What is an exponential function?</h3>
An increasing exponential function is modeled by:
In which:
- A(0) is the initial value.
- r is the growth rate, as a decimal.
In this problem, the function is:
- The initial value is of
.
- The growth rate is of
, as 
.
When t = 5, we have that:

Answer:
Writing a number in standard form simply means to express the number in its 'normal' form. Therefore, your example is written in standard form.
First, how much were her songs? It's two songs each, and their separate prize was 0.99:
total prize was 2*0.99=1.98
this gets added to the membership prize:
19.99+1.98=21.97
you can also calculate this by rounding all the numbers (20+1+1) and substracting the amount you rounded (three times one cent) - the result would be the same.
Answer:
One would be 90° and the other would be 16°
