Answer:

  1.  value is 0; x-3 is a factor . . . . . . . . . . . . . .third choice

  2.  evaluates at x = -1; remainder is -11 . . . . first choice

Step-by-step explanation:

Dividing f(x) by (x -a) gives ...

  f(x)/(x -a) = g(x) +r/(x -a) . . . . some quotient and a remainder r

If we multiply this expression by (x -a), we see ...

  f(x) = (x -a)g(x) +r

so

  f(a) = (a -a)g(a) +r . . . . . evaluate the above equation at x=a

  f(a) = 0 +r

  f(a) = r . . . . . . . . . a statement of the remainder theorem

If r=0, then x-a is a factor of f(x) = (x-a)g(x).

___

1. We have "a" = 3, and f(3) = 0. Therefore (x-3) is a factor.

__

2. We have "a" = -1, and f(-1) = -11. Therefore the remainder from division by (x+1) is -11.

A single , six sided die is rolled . find the probability of rolling an odd number less than 4
Feliz [49]

I don't have a lot of experience with chance, but there are 2 odd numbers before 4, 1 and 3, so it would be 2 out of 6 or 33.3 continuing percent.

The formula for the volume V of a cylinder is V=πr2h, where r is the radius of the base and h is the height of the cylinder. Sel
Alja [10]

Answer:

see explanation

Step-by-step explanation:

Given

V = πr²h ( isolate h by dividing both sides by πr² )

\frac{V}{\pi r^2} = h

When V = 36π , r = 3 , then

h = \frac{36\pi }{\pi (3)^2} = \frac{36\pi }{9\pi } = 4 cm
