the radius: r^2 = 81
r =9
c = 2*pi*r
= 2 * pi * 9
= 18 *pi
Answer: 18*pi or approximately 56.62
Answer:
Final result is 3.
Step-by-step explanation:
Quotient = (60 + 30) / 10
= 90/10
= 9.
Difference of quotient and 3
= 9 - 3
= 6
6 / 2 = 3.
A. 4 (is the only factor for expression -48xyz -24xy +40)
Answer:
Graph B
The graph in the attached figure
Step-by-step explanation:
we have
This is a exponential function
of the form
where
a is the initial value
b is the base
r is the rate
b=1+r
In this problem
a=2 ----> the y-intercept
b=3
so
1+r=3 -----> r=3-1=2 -----> r=200%
so
The y-intercept of the graph is equal to 2
As x increases the value of f(x) increases
therefore
Graph B
