Answer: Richard.
Step-by-step explanation: The question mark for Steve is 55, making the rate of change 110/2 or 55/1, or 1.
Geeta's pay's function is p=75+45h, and 75+45×1=120, 75+45×2=165, and 75+45×3=210. The rate of change for Geeta is 45/1, or 45.
Now, Richard's pay is easy. All u have 2 do is subtract 110-80=30, and subtract 80-50=30. His rate of change is 30/1, or 30.
Answer:
40 bottles for $5.49
Step-by-step explanation:
40 divided by 5.49 will get you 7.28
72 divided by 9 will get you 8
Let x = the shorter leg
2x + 6 is the longer leg
2x + 9 is the hypotenuse
We now do the Pythagorean Theorem of


Multiply out to get:

The

will cancel out each other when you combine like terms to get all the terms on one side of the equal sign.
Combine like terms with the rest to end with

Factor this to get

then set each factor equal to zero.
You end up with two solutions, x = 15 and x = - 3
HOWEVER distance cannot be measure in negatives so that answer will not work so x = 15. Now plug into our given information.
The short leg is 15 cm long.
The longer leg of 2(15) + 6 = 36 cm long
The hypotenuse of 2(15) + 9 = 39 cm long.
You can check your answers by plugging them into the Pythagorean Theorem again.
87 x 57 = 4959
20000/4959 = 4.033071184
