suppose the distnace in feet that an object travels t seconds is given by the formula d=64t^2 how far would the object travel af
Darya [45]

Answer:

The object travels 144,000,000 feet.

Step-by-step explanation:

The distance the object travel after t seconds is given by:

d(t) = 64t^2

How far would the object travel after 1.5 * 10^3 seconds

This is d when t = 1.5 \times 10^3 = 1500, so d(1500)

d(1500) = 64*1500^2 = 144000000

The object travels 144,000,000 feet.

I’m stuck on this question please help
Komok [63]
Take the price of pears (£1.30 per kilogram) and multiply it by the amount of pears (7kg). You get 9.1 so now you take the total amount spent (£12.70) and subtract the 9.1 and you get 3.6 now that is the amount you spent on the apples. So take 3.6 and divide it by the amount of apples you got (2kg) you will get 1.8 and that is your overall answer.

If y varies directly with x, and y = 18 when x = 4, what is the constant of proportionality?
GREYUIT [131]
Y is directly proportional to x and therefore takes the form y=kx where k is the constant of proportionality.

Dividing both sides by x for the given values, k becomes 18/4 = 4.5
