An arrow is shot into the air and its height in feet after seconds is given by the function f(t) = -1612 + 1601. Estimate the instantaneous velocity att = 4 seconds using difference quotients with h = 0.1, 0.01, and 0.001. If necessary, round the difference quotients to no less than six decimal
places and round your final answer to the nearest integer.

true !

step-by-step explanation:

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.

35x 3= 105

step-by-step explanation:

35+35= 70   70 + 35= 105
