soldi70 [24.7K]

The new length of the string will be 16  1/4 feet. Then the correct option is B.

<h3>What is the length?</h3>

It is the measure of distance between the two points and is known as length. The length is measured in meters generally.

Ed needed to extend the string on his kite. The current string was seven and three-fourths feet that is (7  3/4).

The mixed fraction number is coverted into a decimal number.

7  3/4 = 7.75 feet

He cut a piece of string that measured 8.5 feet and added it to the existing string.

Then the new length of the string will be

L = 7.75 + 8.5

L = 16.25

L = 16  1/4 feet

The new length of the string will be 16  1/4 feet. Then the correct option is B.

More about the distance link is given below.

Question
Kay [80]

Answer:

f(x)=2(x-2)(x^2+64)

Step-by-step explanation:

A standard polynomial in factored form is given by:

f(x)=a(x-p)(x-q)...

Where <em>p</em> and <em>q</em> are the zeros.

We want to find a third-degree polynomial with zeros <em>x</em> = 2 and <em>x </em>= -8i and equals 320 when <em>x </em>= 4.

First, by the Complex Root Theorem, if <em>x</em> = -8i is a root, then <em>x </em>= 8i must also be a root.

Therefore, we acquire:

f(x)=a(x-(2))(x-(-8i))(x-(8i))

Simplify:

f(x)=a(x-2)(x+8i)(x-8i)

Expand the second and third factors:

=(x+8i)x+(x+8i)(-8i)\\\\=(x^2+8ix)+(-8ix-64i^2)\\\\=(x^2)+(8ix-8ix)+(-64i^2)\\\\=x^2-64(-1)\\\\ =x^2+64

Hence, our function is now:

f(x)=a(x-2)(x^2+64)

It equals 320 when <em>x</em> = 4. Therefore:

320=a(4-2)(4^2+64)

Solve for <em>a</em>. Evaluate:

320=(2)(80)a

So:

320=160a\Rightarrow a=2

Our third-degree polynomial equation is:

f(x)=2(x-2)(x^2+64)
