It takes 60 oz of grass seed to seed 4200 ftsquared2 of lawn. at this rate, how much would be needed for 7700 ftsquared2 of lawn?

(if f(x)=4x^2 and g(x)=x+1, find (f o g)(x)

G(x) = 2 sin(2x - π) + 4. using complete sentences, explain how to find the minimum value for the function.

How do i start to solve? would appreciate a walk-thru! a bird sitting 16ft above the ground in an apple tree dislodges an apple. after how many seconds does the apple land on the ground? (assuming that no branches will interfere with it's fall)
