Im not sure but I think the answer is most likely...
D) 10.
Hope I helped :-)
Answer:
125π km³
Step-by-step explanation:
We are to find the Volume of a cylinder
From the question:
Height of the cylinder = 5km
Radius of the cylinder = 5 km
The volume of a cylinder =
πr² h
Hence:
π × 5² × 5
= 125π km³
The volume of the cylinder = 125π km³
Option d is the correct option
Answer:9a^2+18a-72
Step-by-step explanation:
9(a+1)^2-81
9(a+1)(a+1)-81
Open brackets
9(a^2+a+a+1)-81
9(a^2+2a+1)-81
9a^2+18a+9-81
9a^2+18a-72
Answer:
D. N(a) = (a + 20)/3
Step-by-step explanation:
A(n) = 3n - 20
A is a function of n. The inverse will be: N is a function of a.
Change A(n) to y and n to x.
y = 3x - 20
Switch x and y.
x = 3y - 20
Solve for y.
x + 20 = 3y
3y = x + 20
y = (x + 20)/3
Now switch y to N(a) and x to a.
Answer: N(a) = (a + 20)/3
Answer:
B C D F
Step-by-step explanation:
well first 4(3+x) simplified would be 12+4x and that is C so thats why C is an answer than it would b
