X^2 - 5x - 7 = 0
x = (-b (+-) b^2 - 4ac) / 2a
a = 1, b = -5, c = -7
x = (-(-5) (+-) sqrt (-5^2) -4(1)(-7)) / 2(1)
x = (5 (+-) sqrt 25 + 28) / 2
x = (5 (+-) sqrt 53) / 2
Answer:
The maximum height of the ball is 28.2 yards.
Step-by-step explanation:
When we have a quadratic equation in the following format:

The maximum value happens when

The maximum value will be 
In this problem, we have that:

So


The maximum height is:

The maximum height of the ball is 28.2 yards.
Answer:
Horizontal shift to the RIGHT of <u>one unit</u>
Step-by-step explanation:
When looking at a square root equation, the transformation form is:

'h' represents a horizontal shift of the graph. Therefore, in this instance:

This means that there is a horizontal shift to the RIGHT of <u>one unit.</u>
Answer:
The length of the longest section x = 36 ft
Step-by-step explanation:
Total length of the wire = 51 ft
Let first section of wire = x
Second section of wire = y
Third section of wire = z
According to given data
x = 3 y & y = 4 z
Total length of the wire = x + y + z = 51


y = 12
x = 3 × 12 = 36

Therefore the length of the longest section x = 36 ft
