An object is launched from the roof of a building 192 feet above the ground. The object's height (in feet)
after t seconds is given by the function
h(t) = -16° +64t + 192
A) What is the height of the object after two-and-a-half
seconds?
252 ft
256 ft
312 ft
620 ft

252 ft

Step-by-step explanation:

h(t) = -16t^2 +64t + 192

We want to find h when t= 2.5

h(2.5) = -16 (2.5)^2 +64(2.5) +192

          =-16(6.25) +160+192

            =-100+160+192

               =252

y=mx+b

the final amount you will pay is $68.04.

the tip is determined by the pre-tax amount, so we calculate the tip based on the original bill, not after we've added sales tax.

to find the tip:

we can divide 54.00 by 100 to get 1% of 54. then we multiply that by 18.

54 / 100 = .54

.54 x 18 = 9.72

tip = 9.72$

to find the tax:

we can divide 54.00 by 100 to get 1% of 54. then we can multiply that by 8 to get 8%.

54 / 100 = .54

.54 x 8 = 4.32

tax= 4.32

now we can add the tip and tax to the bill to get our total.

54 + 9.72 + 4.32 = 68.04

total: $68.04
