Answer:
y = -9
Step-by-step explanation:
divide by 5 first
y + 2 = -7
-2
y = -9
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.

Plugging this into the given formula:

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:

Then by the zero product property (or the no zero divisors rule), we have:

(this is the x value where the ball is kicked from)



So the ball travels 51 yards in total.

Answer:
Real distance between Manchester and London = 263.2 km
Step-by-step explanation:
Given that:
A map has a scale of 1 cm = 14 km
Ratio = 1 : 14
Distance from Manchester to London = 18.8 cm
Let,
x be the real distance between Manchester and London.
Ratio = 18.8 : x
As the relationship is proportional,
1 : 14 :: 18.8 : x
Product of mean = Product of extreme
14*18.8 = x
x = 263.2 kilometers
Hence,
Real distance between Manchester and London = 263.2 km
