AB is parallel to CD.
kogti [31]

Answer:

Step-by-step explanation:

∠ABC = ∠BCD    { AB // CD; BC TRAVERSAL, alternate angles are equal}

∠ABC = 20

∠BCA = ∠BAC     {angles opposite to equal sides are equal}

∠BCA = ∠BAC = x

x + x + 20 = 180

2x = 180 - 20

2x = 160

x = 160/2

x = 80

The path of a football kicked by a field goal kicker can be modeled by the equation y = –0.03x2 + 1.53x, where x is the horizont
netineya [11]
This is the equation of an upside down parabola, so the maximum height will be at the vertex. To find the vertex, we'll use the formula for the x-coordinate and then solve for the y-coordinate.
x=\frac{-1.53}{2*-.03}=25.5

Plugging this into the given formula:
y=-0.03(25.5)^2+1.53(25.5)=19.5075
Since it asks us to round, the maximum height would be 20 yards. To find how far the football travels in total, we need to set the equation equal to 0 and find the roots:
0=-0.03x^2+1.53x=x(-0.03x+1.53)

Then by the zero product property (or the no zero divisors rule), we have:
x=0 (this is the x value where the ball is kicked from)
-0.03x+1.53=0
-0.03x=-1.53
x=51

So the ball travels 51 yards in total.
