Answer: 50 miles
Step-by-step explanation:
ok 1 inch = 16 miles
its 2 1/4 inches from coopertown to center city
16 x 2.25 = 36 miles
then it is 7/8 of an inch to reedville
16 x 7/8 = 14 miles
from coopertown thru center city to reedville it would be
36 miles + 14 miles = 50 miles

Answer:
The height of the highest point of the arch is 3 feet.
Step-by-step explanation:
The complete question is:
A dome tent’s arch is modeled by y= -0.18(x-6)(x+6) where x and y are measured in feet. To the nearest foot, what is the height of the highest point of the arch.
Solution:
The expression provided is:
The equation is of a parabolic arch.
The general equation of a parabolic arch is:
So,
a = -0.18
b = 6.48
c = 0
Highest point of the parabolic arch is the vertex of the parabolic equation if <em>a</em> < 0
.
As <em>a</em> = -0.18 < 0, the ordinate of vertex of equation will give the height of highest point of arch.
For a parabola the abscissa of vertex is given as follows:
⇒
Compute the value of <em>y</em> as follows:
Thus, the height of the highest point of the arch is 3 feet.
