Answer:

Trent is wrong.

This is because:

π = 25.12/2 × 5

π = 25.12/8

Step-by-step explanation:

A pizza is circular is shape, the formula for the circumference of a circle is :

C = 2× π × r

Making π the subject of the formula

π = C/2r

The circumference of the pizza is 25.12 inches. The radius of the pizza is 4 inches,

Hence:

π = 25.12 inches/ 2 × 4 inches

π = 25.12/8

From the calculation above, Trent is wrong.

Ahat [919]

The percent increase in enrollment is 6 %

The operation used in first step is finding the difference between final value and initial value

<h3><u>Solution:</u></h3>

Given that This year, 1,272 students enrolled in night courses a a local college

Last year only 1,200 students enrolled.

To find: percent increase in the enrollment

The percent increase between two values is the difference between a final value and an initial value, expressed as a percentage of the initial value.

<em><u>The percent increase is given as:</u></em>

\text { percentage increase }=\frac{\text { final value - initial value}}{\text { initial value }} \times 100

Here initial value (last year) = 1200 and final value(this year) = 1272

Substituting the values in above formula,

\begin{aligned}&\text { percentage increase }=\frac{1272-1200}{1200} \times 100\\\\&\text { percentage increase }=\frac{72}{1200} \times 100=6\end{aligned}

Thus percent increase is 6 %

<h3>Answer: D) common ratio</h3>

Explanation:

The four points on this curve are

(1, 3) ,  (2, 6),  (3, 12) ,  (4, 24)

The equation of the curve that goes through all the points mentioned is

y = 3*2^(x-1) which is equivalent to y = 1.5*2^x

Both equations are exponential equations.

Sequences of the form

a(n) = a*(r)^(n-1)

are geometric sequences with common ratio r. In this case, r = 2.

Note how the jump from 3 to 6 is "times 2", so is from 6 to 12, and from 12 to 24. We multiply each term by 2 to get the next one.
