statuscvo [17]

Answer:

A.there are 3 terms.

B.the variables are x, y, and z.

Step-by-step explanation:

Complete question below:

Consider the following expression and determine which statements are true. x^2+5yz−8

CHOOSE 2 ANSWERS)

A.there are 3 terms.

B.the variables are x, y, and z.

C.The coefficient of x is 2.

D.the term 5yz is made up of 2 factors

The expression x^2+5yz-8

has three terms namely: x^2, 5yz and -8

The variables are x, y and z

The coefficient of x is 1 not 2, so option c is wrong

The term 5yz is made up of more than two factors namely 5, y, z, 5y, 5z, 5yz . So option d is also wrong.

The correct answers are option a and option b

A.there are 3 terms.

B.the variables are x, y, and z

What is the volume of a sphere with a radius of 8 m, rounded to the nearest tenth of a cubic meter?

zlopas [31]

<h3>given:</h3>

radius= 8 m

the volume of the sphere

<h3>solution:</h3>

$v = \frac{4}{3} \pi {r}^{3}$

$v = \frac{4}{3} \times \pi \times {8}^{3}$

$v = 2144.66058 \: {m}^{3}$

$v = 2144.7 \: {m}^{3}$

therefore, the volume of the given sphere is 2144.7 cubic meters.
