Answer:
m = - 1
Step-by-step explanation:
1/4 of 20 is 5
A is the answer
f(x) = -(x+2)(x-1)
We know the zeros are at 1 and -2
f(x) = a *(x-b1)(x-b2) where b1 and b2 are the zeros and a is a constant
f(x) =a(x-1)(x- -2)
f(x) =a(x-1)(x+2)
We know that a must be negative since the parabola opens down so
The only choice is choice D where a = -1
512000
l=80cm
v=l^3
=80^3
=512000cm^3
The standard form of is 0.0000002
