after 1 second the ball is 76 feet in the air: after 2 seconds it is 144 feet in the air. Find the height of the function. h(x)= ?

Answers

Answer 1
Answer: General equation for height, h
h = ut + 0.5gt^2

at t=1s, h = 76 feet
76 = u*1 + 0.5*a*1^2
76 = u + 0.5a

at t=2s, h = 144 feet
144 = u*2 + 0.5*a*2^2
144 = 2u + 2a
72 = u + a

Subtract 2 equations
0.5a = -4
a = -8
u = 80

So the equation,
h(x) = 80t + 0.5*(-8) t^2
h(x) = 80t - 4t^2

a restaurant manager gives a survey to all of his customers asking them to rate the quality of the service they received. he then keeps track of how many customers return to the restaurant during the next six months. last year, the results showed that of the customers who reported high quality service, 90% returned for additional meals. what conclusion can be drawn from this study. answer choices: only some customers who rate their service as high quality return for additional meals. most customers who rate their service as high quality return for additional meals. high quality services cause customers to return for additional meals. customers who will return for additional meals report a high quality of service.

Answers

I am going with : most customers who rate their service as high quality return for additional meals. Because 90% who rated it as high quality returned for additional meals.....only 10% did not. And lets say u had 100 customers that rated high quality.....90 returned and 10 did not...so that is most customers.

Answer:

Most customers who rate their service as high quality return for additional meals.

Step-by-step explanation:

Only some customers who rate their service as high quality return for additional meals.  - its not this because it says only SOME and 90% is not some it is MOST but not all.

High quality services cause customers to return for additional meals  - just because the restaurant has high quality service that doesn't mean that this causes them to come back for an additional meal.

Customers who will return for additional meals report a high quality of service. - its not this because it just doesn't make sense.
