<span>The answer two this question is C.

You can get this answer by multiplying the two polynomials and then simplifying. See the steps below:
(4x^2 - 5)(x + 3) ---> Now multiply the two parenthesis. 
4x^3 - 5x + 12x^2 - 15 ---> Arrange the numbers by decreasing  exponents. 
4x^3 + 12x^2 - 5x - 15

No simplifying can be done since there are no like terms. </span>

Answer: fg(x)=4x^3+12x^2-5x-15

Step-by-step explanation:

Given: f(x)=4x^2-5\text{ and } g(x)=x+3

We know that for any function f(x) and g(x), the multiplication function (fg) (x) is given by :-

fg(x)=f(x)g(x)

Now, for the given functions, we have

fg(x)=(4x^2-5)(x+3)\\\\\Rightarrow\ fg(x)=4x^2(x+3)-5(x+3)\\\\\Rightarrow\ fg(x)=4x^3+12x^2-5x-15

A regular hexagon has an apothem measuring 14 cm and an approximate perimeter of 96 cm.
Mariulka [41]

ANSWER

672cm²

EXPLANATION

The area of a regular hexagon is given by the formula,

Area =  \frac{1}{2} ap

where a=14cm is the apothem and p=96cm is the perimeter of the regular hexagon.

We substitute the values into the formula,

Area =  \frac{1}{2}  \times 14 \times 96 {cm}^{2}

Area =672 {cm}^{2}

Therefore the approximate area of the hexagon is 672cm²

the form y=axPlot five points on the graph of the function: one point with x=graph-a-function button.10130141
kifflom [539]

At first let us choose the 5 points

at x = 0, y = 0

The first point is (0, 0)

y=ax^3

We will choose a = 1/2

The points are

(-2, -4)

(-1, -1/2)

(0, 0)

(1, 1/2)

(2, 4)

y=\frac{1}{2}^{}x^3
