<h3>Hello there!</h3>

In this question, we have to turn the given information into function notation.

Function notation is f(x) = (expression)

From the information given, we know that:

  • Earns $15 each hour
  • Gets a $25 bonus

Now, we turn it into an equation.

We would write the equation as y = mx + b

m = rate

x = hours

b = bonus

This means that our equation would be:

y = 15x + 25

Now, we can write it as a function notation.

f(x) = 15x + 25

<h3>Answer: f(x) = 15x + 25</h3><h3>I hope this helps!</h3><h3>Best regards,</h3><h3>MasterInvestor</h3>

Find two positive angles and two negative angles that are coterminal with the given angle and less than 1080 but greater than 72
ivann1987 [24]

Answer:

The correct answer is 450°, 810°, -270° and -630°.

Step-by-step explanation:

According to the given scenario, the calculation of the two positive angles and two negative angles i.e. coterminal is as follows:

The coterminal angles are the angles in which the difference could be 360 degrees or the multiples of 360 degrees

For 90 degrees, the two positive angles are

a. 90° + 360°

= 450°

450° + 360°

= 810°

b. The two negative angles are

= 90° - 360°

= -270°

-270° - 360°

= -630°
