Exponential decay can be represented in two ways.

By having y=a^{-x} with a>1

By having y=a^x with 0

The only alternative that satisfies one of the conditions is letter C

Hello and Good Morning/Afternoon

<u>Let's take this problem step by step</u>:

<u>To find the rate of change is essentially like finding a line's slope</u>:

 ⇒ the <em>x-values</em> are the <em>number of sodas</em>

 ⇒ the<em> y-values </em>are the <em>total costs</em>

<em>               ⇒ choose</em> two sets of coordinates and find the slope

<u>Let's put that into action</u>

  • Choose any two points

        ⇒ (24, 18)

        ⇒ (28, 21)

  • Calculate Slope

        Rate_.of_.change = \frac{21-18}{28-24} =\frac{3}{4}

<u>Since the rate of change is total cost over number of sodas</u>

 ⇒ <em>unit is '</em>total cost/number of sodas'

<u>Answer: 3/4 total cost/number of sodas</u>

<u></u>

Hope that helps!

What is the answer !​
kondor19780726 [428]

Answer:

m∠OKG = 95°

Step-by-step explanation:

In the given question,

Angle OKL and angle OKG are the linear pairs.

And we know that sum of linear pair of angles is 180°.

Therefore, m∠OKL + m∠OKH = 180°

85° + m∠OKH = 180°

m∠OKH = 180° - 85°

              = 95°

Therefore, measure of angle OKG = 95° will be the answer.

A high school sports team is ordering sports drinks online from a company. The price of sports drinks varies, based on the numbe
Elena-2011 [213]

The amount of drinks is a linear function of the number of drinks. The maximum amount that can be purchased is 100 soft drinks.

Let

y \to amount of drinks

x \to number of drinks

For drinks not more than 50

y = 10 + 0.8x

For drinks more than 50.

y = 15 + 0.7x

For a purchase of $85, it means that:

y = 85

So, we solve for x in both equations.

y = 10 + 0.8x

85 = 10 + 0.8x

Collect like terms

0.8x = 85-10

0.8x = 75

Divide through by 0.8

x = 93.75

x = 94 --- approximated

y = 15 + 0.7x

85 =15 + 0.7x

Collect like terms

0.7x = 85 - 15

0.7x = 70

Divide by 0.7

x = 100

By comparing both values:

x = 100

x = 94

100 > 94

Hence, the maximum amount that can be purchased is 100

Alexxx [7]

Answer:

y= 3x

Step-by-step explanation:

This is honestly your basic times tables if we are being honest. We know that she read 3 paragraphs per minute. We also know that in 4 minutes, she read 12 paragraphs. 4 times 3 = 12. So the answer is y=3x.
