Little Frufru is standing at the top of a lighthouse. She is 96 feet above the ocean. She tosses a ball into the air. The height, h, of the ball after x seconds is given by
h = - 16t^2+64 + 96. How many seconds does it take to reach the maximum height

4.62 seconds

Step-by-step explanation:

Time is displacement divided by average speed.

Average speed w = (u+v)/2 = (64-83.9)/2 ft/s

Time t = s /w

t = -46(2/(64-83.9) = -92/-19.9 = 4.62 seconds.

answer: the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.

step-by-step explanation:

the given rate of interest i= 85%

in calculating the monthly payment for a loan with an interest rate compounded monthly, the value of the interest rate per period we use in the formula must be in decimal form.

to convert it in decimal, we divide it by 100, we get

hence, the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.
