Answer:

+2

Step-by-step explanation:

=> (2-3x)(x^2-5)

=> (2x^2-10-3x^3+15x)

<em>Arranging it in descending order</em>

=> -3x^2+2x^2+15x-10

<u><em>So, the coefficient of x² in this expression is +2</em></u>

This depends if you are supposed to simplify the binomials first:

If you leave it in the form provided then the coefficient would be 1

However, you can multiply the binomials together in order to simplify the expression:

(2 - 3x)( {x}^{2}  - 5)

(2  \times  {x}^{2} ) + (2 \times  - 5) + ( - 3x \times  {x}^{2} ) + ( - 3x  \times  - 5)

{ - 3x}^{3}  +  {2x}^{2}  + 15x - 10

Which then shows the coefficient would be 2

So it all depends on the directions provided, I would assume the correct answer is 2 if the directions are the exact same as provided on Brainly.

Julie and her brother go to Atlanta to ride the SkyView Ferris wheel. It measures 200 feet in diameter.

Answer:

Part A) Circumference

Part B) C=\pi D

Part C) The distance traveled in one rotation is 628.32 feet

Step-by-step explanation:

Part A) we know that

The distance around the circle is equal to the circumference.

The Ferris Wheel have a circular shape

so

To find out the distance around the Ferris Wheel you should use the circumference

Part B) What is the formula needed to solve this problem?

we know that

The circumference is equal to multiply the number π by the diameter of the circle

so

C=\pi D

Part C) What is the distance traveled in one rotation?

we know that

One rotation subtends a central angle of 360 degrees

The distance traveled in one rotation is the same that the circumference of the Ferris wheel

we have

D=200\ ft ----> diameter of the Ferris wheel

substitute in the formula of circumference

C=\pi (200)\\C=200\pi\ ft

assume

\pi=3.1416

C=200(3.1416)=628.32\ ft

therefore

The distance traveled in one rotation is 628.32 feet
