HELP PLEASE!!!!!!!!!!!!!!!!!!!!!

Answer:

Step-by-step explanation:

Let x represent the number of cars that Jamie washes.

Let y represent the number of pies that Stella makes.

The amount of money needed by Jamie and Stella to sign up for the trip is $600 each

Jamie earns $25 for each car washed. This means that if he washes x cars, he would earn 25×x =$25x

Stella earns $15 for each pie made.

This means that if she makes y pies, she would earn 15×y =$15y

Part 1) The inequality is

25x greater than or equal to 600

Part 2)The inequality is

15y greater than or equal to 600

Part 3) Stella only has enough supplies to make 40 pies. Total amount made from 40 pies would be 40×15 = 600

Jamie's earnings is

25x greater than or equal to 600

Stella's earnings is

15y lesser than or equal to 600

Part 4) Maximum amount of money that Stella can earn is 15×40 = $600

Therefore, Stella can afford to sign up for the trip.

A particular sound wave can be graphed using the function y = 1 sin 2x . Find the amplitude of the function.
tiny-mole [99]
Answer: 1

--------------------------------------------------------------

The equation y = 1*sin(2x) is in the form y = a*sin(bx-c)+d
where
a = 1
b = 2
c = 0
d = 0
The value of 'a' determines the amplitude
amplitude = |a| = |1| = 1
