Answer:
Justin has a lower mean tip for the week with $42.
Step-by-step explanation:
To find the mean you must add all the numbers and then divide the sum by how many numbers there are.
For Justin you must add 32 + 45 + 50 + 33 + 50 then you'll get the sum 210. There are 5 numbers so you divide 210 by 5 which gives you the quotient 42.
As for T.J. you add 58 + 48 + 40 + 42 + 42 which gives you the sum of 230. Then you divide 230 by 5 since there's 5 numbers. Now you have the quotient of 46.
46 is greater than 42 so Justin has the lower mean.
Quadratic function whose zeros are 5 and -7 is x^2+2x-35=0
Step-by-step explanation:
Write a quadratic function h whose zeros are 5 and -7
If 5 and -7 are zeros of quadratic function then:
x=5 and x=-7
or x-5 = 0 and x+7=0
So, Finding quadratic equation:
So, quadratic function whose zeros are 5 and -7 is x^2+2x-35=0

Hi Lawrence!
---------------------------------------------------
We Know:
Powersports Plus: $30 an hour plus a non-refundable deposit of $50.
Sun & Surf: $20 an hour plus a non-refundable deposit of $80.
---------------------------------------------------
Equation:
x = per hour
y = total
Powersports: 30x + 50 = y
Sun and Surf: 20x + 80 = y
---------------------------------------------------
Solution: (Add the deposit then start adding hourly costs)
Powersports: 80, 110, 140
Sun and Surf: 100, 120, 140
---------------------------------------------------
Answer: After <u>3 hours</u> both companies will cost the same amount of money.

Answer:
Inverse = (arcos x) / 2.
Step-by-step explanation:
y = cos 2x
2x= arcos y
x = (arcos y) / 2.
Inverse = (arcos x) / 2.
