The quadratic function y(t) = 13.5t - 4.9t2 gives the distance y, in meters, a golf ball travels in the vertical direction in t seconds. Graph the function on the grid by plotting the zeros of the function and several other points to fill out the shape of the curve. Use the graph to approximate the time at which the golf ball reaches its maximum height.

f(2x−x2)=−3x2+6x−1

step-by-step explanation:

set up the composite function and evaluate.

f(2x−x2)=−3x2+6x−1

answer: 177/8

step-by-step explanation:

the workers who do no drive has no reasonable reason to buy gasoline due to they don't have anything to use it for

answer: the angel abc is 30°,and the abc is a triangle where the angel bac is 90°

so ac is the half of 24=12ft,and from the pythagorean theorem we find ba

ba=√bc^2-ac^2=√576-144=√432=12√3ft

so bac is 12+12√3=12(1+√3)ft
