Step-by-step explanation:
s = 2pirh
s ÷ 2 = pirh
s ÷ 2pi = rh
s ÷ 2pih = r
Answer: - 10
+ 3x - 4
Step-by-step explanation:
Factor to find x intercepts
x intercepts occur where f(x)=0
so
0=f(x)=x^2-5x+4
what2 numbers multiply to get 4 and add to get -5?
-4 and -1
0=(x-4)(x-1)
set to zero
x-4=0
x=4
x-1=0
x=1
x intercepts at 1 and 4
so therefor it is the 3rd option
You can use two variables in an equation, just substitute it in.
