Answer:
Step-by-step explanation:
<u>Given:</u>
- f(x) = - x² - 1
- g(x) = x + 5
<u>Find f(g(x)):</u>
- f(g(x)) =
- f(x + 5) =
- - (x + 5)² - 1 =
- - x² - 10x - 25 - 1 =
- - x² - 10x - 26
Answer:
<u>The measurement of the circumference of this circle is 23.9 ft.</u>
Step-by-step explanation:
Let's recall that the circumference formula is:
C = 2πr or C = πd, where:
r = radius = 7.6/2 = 3.8 ft
d = diameter = 7.6 ft
In consequence, we have:
C = 3.14 * 7.6
C = 23.864
<u>C = 23.9 ft</u>
