Answer:
all x intercepts [-4, 0] [4, 0]
Step-by-step explanation:
x-intercept, i.e. y=0
f(x) = x^3 - 4x^2 - 16x + 64 = 0
(x^3 + 4^3) - 4x^2 - 16x = 0 [FYI, x^3 + y^3 = (x + y)(x^2 - xy + y^2)]
(x + 4)(x^2 - 4x + 16) - 4x^2 - 16x = 0
(x + 4)(x^2 - 4x + 16) - 4x(x + 4) = 0
(x + 4)(x^2 - 4x + 16 - 4x) = 0
(x + 4)(x^2 - 8x + 16) = 0
(x + 4)(x - 4)^2 = 0
x = -4 or 4
all x intercepts [-4, 0] [4, 0]
Answer:
See below.
Step-by-step explanation:
The equation is this
A= 1/2bh
We plug in the equation and we get this
A= 1/2 (14)(24)
Let's do the math.
A= 1/2 (336)
A= 168
That's your answer. ✌️
I hope this helps!
The answer is 500,000 because you have add a zero sense it's times 10
A = (45/360)×16^2×pi
A = 32pi
