Answer:
- 439
Step-by-step explanation:
evaluate f(- 7) and substitute the value obtained into s(x)
f(- 7) = 3(- 7) = - 21 , then
s(- 21) = 2 - (- 21)² = 2 - 441 = - 439
Answer:
Radius: 10 ft
Diameter: 20 ft
Area: 314.15 ft^2
Circumference: 62.83 ft
Step-by-step explanation:
The radius can be found using the diameter. The diameter is 20 feet which is the line that is given in the circle.
The radius(r) is equal to half the diameter(d):
r = d/2 --> r = 20/2 = 10 feet
The area(A) can be found using the radius(r) and pi or 3.14
A = pi(r^2) --> A = pi(10^2) = 314.15 feet^2
The circumference(C) is found by using the radius(r) and pi or 3.14
C = 2pi(r) --> C = 2pi(10) = 62.83 feet
Answer:
5 times 12 = 12 times 5
Step-by-step explanation:
You flipped the factors since they were the same. 5 times 12 = 60 when you flip the factors 12 times 5 = 60
