Answer:
2
Step-by-step explanation:
The equation can be rewritten as ...
... (x -5)² + (y +3)² = 0 . . . . . . a circle of radius 0 centered at (5, -3)
This is the equation of the point (5, -3). So, ...
... x + y = 5 - 3 = 2

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.
7/4=(4+3)/4=4/4+3/4=1+3/4=1 3/4.
Answer: 7/4 is as a mixed number 1 3/4.
