Answer:
Hello first one is 4.
Second one is 8
Step-by-step explanation:
First one is f(0). It means you should put zero in the place of x
0 is less than 5 so you should put zero in x+4=f(x)
For the second one do like the first one.
I hope you understand
7x+2=23
Move 2 to the other side
7x=23-2
7x=21
To isolate the x divide both sides by 7
x=3
To check plug the value of x back in
7(3)+2=23
21+2=23
23=23
Answer:
Step-by-step explanation:
Formula
V = pi * r^2 * h
Givens
h = 22 cm
r = d/2 = 7/2
r = 3.5
pi = 3.14
Solution
V = 3.14 * 3.5^2 * 22
V = 846.23 cm^3
