F varies directly with m and inversely with the square of d . If F = 60 when m = 1470 and d = 7 , find F when m = 2560 and d = 8

80 is the answer

Step-by-step explanation:

The direct variation is given by:

So given the values for each variable, we can find the constant of proportionality k:

Then we can now find what the value is when m = 2560 and d = 8 by using the proportionality equation with k = 2:

a) t'(-3, 6) and v'(0, 3)
