The number of infections in week 8 will be 172 people
<h3>How to know an exponential table? </h3>An exponential function is defined by the formula f(x) = aˣ, where the input variable x occurs as an exponent.
According to the reports, the reported infections are growing at a rate of 20%.
Therefore, the exponential function is as follows:
A = 40(1 + 20%)ⁿ
where
Hence,
Number people = 40(1 + 0.2)ⁿ
when n = 8 weeks
A = 40 (1 + 0.2)⁸
A = 40 (1.2)⁸
A = 40(4.29981696)
A = 171.9926784
A = 172
Therefore, the number of infections in week 8 is 172 people.

Answer:
Height of shuttle at that instant = 1.17 miles
Step-by-step explanation:
Refer the given figure.
C is the position of rocket and B is the position of observer.
Here we need to find AC, that is the height of shuttle at that instant.
Using trigonometric rules on ΔABC, we have
Height of shuttle at that instant = AC = 1.17 miles
