A baseball is thrown with a vertical velocity of 40 ft/s from an initial height of 7ft. The height h in feet of the baseball can be modeled by h(t)=-16t^2+40t+7, where t is the time in seconds since the ball was thrown.

Approximately how many seconds does it take the ball to reach maximum height? Round your answer to the nearest tenth.

step-by-step explanation:

step-by-step explanation:

∆abc has the points a(1, 7), b(-2, 2), and c(4, 2) as its vertices. formed with the point d(1, 2) as its third vertex, then ∆abd is triangle.

the area of the rectangle is 35units^2.

step-by-step explanation:

graph it and find the distance.

it is a 5*7 rectangle.

therefore the area is 35units^2.
