Answer:
Width of the archway at its base: 11 units, height of the archway at its highest point: 30.25 units.
Step-by-step explanation:
The graph that represents the equation 
is now sketched with the help of a graphing tool and whose representation is included in a file attached below. The point associated with x-intercepts are (-3, 0) and (8, 0) and the point associated with the highest point is (2.5, 30.25). The width of the archway at its base (
) and the height of the archway at its highest point (
) are, respectively:
Width of the archway at its base: 11 units, height of the archway at its highest point: 30.25 units.

Answer:
u^2- 18u +81 = (u-9)^2
Step-by-step explanation:
u^2- 18u +
Take the u coefficient
-18
Divide by 2
-18/2 = -9
Square it
(-9)^2 = 81
u^2- 18u +81 = (u-9)^2
A - quantity tickets for adults. It costs 5a dollars
c - quantity tickets for children. It costs 2c dollars.
There were 1750 tickets sold, so a+c=1750$. That's mean a = 1750 - c.
Total: 7 100$, That's mean 5a + 2c = 7 100. Substitute now 1750-c instead "a" :
5(1750-c) + 2c = 7100
8750 - 5c + 2c = 7100
-3c = -1650 |divide (-3)
c = 550
So a =1750 -c = 1750 - 550 = 1200
There were sold 1200 tickets for adults and 550 tickets for children
