Answer:
Step-by-step explanation:
if x= -2
and P(x)=x^4+4x^3+6x^2-8
then P(-2)=(-2)^4+4*(-2)^3+6*(-2)^2-8=16-32+24-8=0
so P(x)=(x+2)* Q(x) and P(x) is divisible by x+2
The formula for finding a volume of a cone is
V=πr^2h(1/3)
Plug in the values the have given you and solve.
3.14(7)^2(3)(1/3)
approx. 153.86 cubic ft.
Answer:
x= 10/3
Step-by-step explanation:
1/250 : 2 = 1/150 : x
it's a simple problem of ratio and proportion
1/250 : 2 = 1/150 : x
⇒
⇒
x= 10/3
Answer:
y = 20
Step-by-step explanation:
take the 2's multiply them =4 (2 x 2 = 4) so 5 x 4 = 20
