Blake gives piano lessons in the evenings.
Aliun [14]

Answer:

<u>The correct answer is B. {0, 20, 40, 60, 80, 100, 120}</u>

Step-by-step explanation:

1. Let's check all the information given to answer this question correctly:

Rate of each piano lesson Blake gives = US$ 20

Blake can give between 0 and 6 lessons every evening

Earnings = Number of lessons * Rate of each lesson

2. What is the range of this relation?

Let's recall that the domain of a relation is the set of all values for which the relation is defined, and the <u>range</u> of the relation is the set of all values that the relation takes.

It means that the domain of the relation in this case is the number of lessons that Blake can give every evening:

{0, 1, 2, 3, 4, 5, 6}

And the <u>range </u>of this relation is the amount Blake earns in an evening depending on the number of lessons he gives:

{0, 20, 40, 60, 80, 100, 120}

<u>The correct answer is B. {0, 20, 40, 60, 80, 100, 120}</u>

1. y=900(1.27)^x
Sophie [7]

Answer:

The initial value is 900

It is experiencing exponential growth by 27%

Step-by-step explanation:

Exponential functions are in the form y=a(b)^x, where a is the initial value, b is the multiplier, and x is the input, such as how many years past a certain date.

Exponential growth is when the multiplier is above 1.00, or above 100%, because b is determined by 1 + r if you have exponential growth, or 1 - r if you have exponential decay. You will never use negatives with exponential decay.
