Answer:
17.83
Step-by-step explanation:
d = r*t
d = 41 miles
t = 2.3 hours
r = ??
d = rt Substitute
41 = r * 2.3 Divide by 2.3
41 / 2.3 = r Switch sides
r = 41/2.3
r = 17.83 mph Answer
Answer:
The no. of subscribers of the magazine after 5 years is = 55713
Step-by-step explanation:
Given data
Total subscribers (N) = 72000
Drop in subscriptions in each year (R) = 5%
No. of subscribers of the magazine in 5 years is given by

= 55713
Thus the no. of subscribers of the magazine after 5 years is = 55713
The results for the matching between function and its period are:
- Option 1 - Letter D
- Option 2 - Letter A
- Option 3 - Letter C
- Option 4 - Letter B
<h3>What is a Period of a Function?</h3>
If a given function presents repetitions, you can define the period as the smallest part of this repetition. As an example of periodic functions, you have: sin(x) and cos(x).


The period of sin(x) and cos(x) is 2π.
For solving this question, you should analyze each option to find its period.
1) Option 1

Thus, the option 1 matches with the letter D.
2) Option 2

Thus, the option 2 matches with the letter A.
3) Option 3

Thus, the option 3 matches with the letter C.
4) Option 4

Thus, the option 4 matches with the letter B.
