Answer:
2 7/8
Step-by-step explanation:
Throwing a ball, shooting a cannon, diving from a platform and hitting a golf ball are all examples of situations that can be modeled by quadratic functions. ... In many of these situations you will want to know the highest or lowest point of the parabola, which is known as the vertex.
Slope formula is
m = (y2 - y1)/(x2 - x1)
A. m = (5 - 0)/(-2 + 2)
m = (5)/(0)
m = error
B. m = (-2 - 0)/(0 + 2)
m = (-2)/(2)
m = -1
C. m = (2 - 0)/(2 - 0)
m = (2)/(2)
m = 1
D. m = (0 - 0)/(2 - 3)
m = (0)/(-1)
m = 0
the undefined slope would be the one that came out as error, so A
We will have to use the formula for the area of a trapezoid on this problem, which is (
and 
are the bases of the trapezoid and 
is the height):
All we need to do is substitute the information we are given into our formula:
Now, let's just simplify the equation:
The missing base has a length of 13 units.
