Answer: 197.92 square inches
step by step:
volume of a cone is V=πr^2h/3
1. divide diameter by 2 to find radius
r = diameter/2
r = 6”/2
r = 3”
2. plug in known values of r and h to find V
V = πr^2h/3
V = π(3”)^2(21”)/3
V = π(9”)(7”)
V = 197.72 square inches
I think the answer is D...hope this help
Put n=2 ,
f(2+1) = f(2) => f(3) = f(2) = 9
now, put n=1,
f(1+1) = f(1) => f(2) = f(1) = 9
Assuming the exponent is supposed to be "^2" your equation will read:
4x² + 8x - 5
It must set equal to y to be a valid function and the y must be set equal to zero to find x-intercepts.
4x² + 8x - 5 = 0
4x² - 2x + 10x - 5 = 0
2x(2x - 1) + 5(2x - 1) = 0
(2x + 5)(2x - 1) = 0
Set each binomial equal to zero.
2x + 5 = 0
2x = 0 - 5
2x = - 5
Divide both sides by 2
x = - 5/2
2x - 1 = 0
2x = 0 + 1
2x = 1
x = 1/2
Your x-intercepts are x = - 5/2, 1/2 or (- 5/2, 0) and (1/2, 0)
