Anyone have the answer to this? Need help ASAP?
larisa [96]

For this case we have the following data:

Polynomial function of grade 5

Given roots: -2, 2,4 + i

Having an imaginary root given by a + bi, the other root, in the same imaginary way, must be given by its complex conjugate, that is, a-bi.

In this way, the fourth root is given by:

4-i

Since the polynomial function is grade 5, it must have 5 roots. Thus, the fifth root must be given by a real number.

Thus, the roots of the polynomial function are given by: three real roots and two imaginary roots.

Answer:

Option D

Question 24 points)Bill cuts a circle out of a square piece of wood to use for a project.Approximately how much wood will be lef
maks197457 [2]

The square piece of wood measures 32 in per side,

Then the circle that can be cut off it has a radius of 16 in (half of the diameter 32 in)

Therefore, the area of the circle is going to be given by the formula:

\begin{gathered} \text{Area}=\pi R^2 \\ \text{Area}=\pi(16)^2\text{ }\approx803.\, 84in^2 \end{gathered}

And the area of the initial square was:

Area = 32^2 in^2 = 1024 in^2

Therefore the left-overs of the piece of wood would be the difference:

1024 in^2 - 803.84 in^2

Assume f(x)=2x+8 and g(×)=5 what is the value of (g o f)(3)
RUDIKE [14]
We first need to find f(3).

f(3) = 2(3) + 8

f(3) = 6 + 8

f(3) = 14

We now want g(f(3)).

We know that f(3) is 14.

We also know that g(x) is 5.

As you know, 5 is a constant. No matter what the value of x is for g(x), it will not change the value of g(x).

So, g(f(3)) = g(14) = 5.

Answer: g(f(3)) = 5.
