Answer:
A. 62.8 in.
Step-by-step explanation:
Circumference of a circle = πd
Diameter (d) = 20 in.
Substitute
Circumference = π × 20
Circumference = 62.8318531
Circumference = 62.8 in. (Approximated to nearest tenth)
Answer:
25
Step-by-step explanation:
range = largest value - smallest value (123-25)
The theorem does not apply.
1. Set the function f(x)=sqrt(x-1) equal to 0 to find what values of x make f(x) defined. So:
x - 1 is < or = to 0
x > or = to 0
2.) find the values where x is defined:
x - 1 > or = to 0
x > or = to 0
Domain = all values of x that define f(x)
[1,infinity)
{x|x> or = to 1}
DNE because 1 is not in the domain because (1-1)^1/2 = 0.
D. 18%
Cuz .18 multiply by 100 is 18
To calculate the angles inside a regular octagon, you have to use the formula: (number of sides -2) x 180
(n-2) x 180
(8-2) x 180
so 8-2 is 6 and 6 x 180 = 1080
Because all of the angles in a regular octagon are congruent (the same), if you divide 1080 by 8, you will get each angle
= 135
