We have that
![y=- x^{2} +36](https://tex.z-dn.net/?f=y%3D-%20x%5E%7B2%7D%20%2B36)
we know that
Is the equation of a vertical parabola open down
so
the vertex is a maximum
step 1
convert the equation of the parabola in the vertex form
![y=- x^{2} +36 \\ y-36=- x^{2}](https://tex.z-dn.net/?f=y%3D-%20x%5E%7B2%7D%20%2B36%20%5C%5C%20y-36%3D-%20x%5E%7B2%7D%20)
the vertex (h,k) is the point (0,36)
Part a) The point on the graph where the height of the tunnel is a maximum is (0,36)
Part b) The points on the graph where the height of the tunnel is zero feet is when y=0
so
for y=0
![- x^{2} +36=0 \\ x^{2} =36 \\ x= (+/-) 6](https://tex.z-dn.net/?f=-%20x%5E%7B2%7D%20%2B36%3D0%20%5C%5C%20x%5E%7B2%7D%20%3D36%20%5C%5C%20x%3D%20%28%2B%2F-%29%206)
the points are (-6,0) and (6,0)

Explanation:
The answer depends on the question, what’s the question, the question is I need the answer to the question, and since the answer depends on the question, then anything I put is the answer.
So you start of by makig the denominator the same so you would multiply 2 by 4 to get 8 on the left and then multiply 5 by 1 to get five allowing you multiply 5 by 2 to get a common denominator that means so far we have 8/10 and 5/10 then you would just take them away from each other giving you 3/10
Answer:
answer is 36 centimeter
Step-by-step explanation:
volume of a cylinder=πr^2h
1696=3.14*r^2*15
1696=47.1=r^2
1696-47.1=r^2
1648.9=r^2
=r
40.60 =r
here according to the question and option given 40.60 is closest to 36 centimeters.so answer is option d.
![\frac{a - c}{x - a}](https://tex.z-dn.net/?f=%20%5Cfrac%7Ba%20-%20c%7D%7Bx%20-%20a%7D)
= m Multiply both sides by (x - a)
a - c = m (x - a) Use the Distributive Property
a - c = mx - ma Add ma to both sides
a - c + ma = mx Divide both sides by m
![\frac{a - c + ma}{m}](https://tex.z-dn.net/?f=%20%5Cfrac%7Ba%20-%20c%20%2B%20ma%7D%7Bm%7D%20)
= x Switch the sides to make it easier to read
x = <span>
