#1) 4.445 ft
#2) yes
Explanation
#1) The maximum height is the y-coordinate of the vertex. We first find the axis of symmetry, given by x=-b/2a:
x=-0.17/2(-0.005) = -0.17/-0.01 = 17
Plugging this into the equation,
y=-0.005(17²)+0.17(17)+3 = 4.445
#2) Substituting 30 into the equation,
y=-0.005(30²) + 0.17(30) + 3 = 3.6
The ball will 3.6 in the air, so yes, it will clear the 3 ft tall net.
Point slope form is y-y1=m(x-x1)
M is the slope
y1 and x1 come from the point given
Answer:
Y+8=1/2(x-0)
If it should be simplified y+8=1/2x
The x value is 0 because when the line intercepts the y axis x=0
7 1/2 x 3 3/4 x 2, to get the answer. The answer is
56 1/4 feet squared
