The path followed by a roller coaster as it climbs up and descends down from a peak can be modeled by a quadratic function, wher
Romashka [77]

Answer:

y = -0.1x^2 + 250 ft

Step-by-step explanation:

Because this quadratic equation would have the curve-down form of:

y = -ax^2 + b

where a and b are positive coefficient.

If we let the peak (250 ft) of the curve be at x = 0. Then

y = -a0^2 + b = 250

b = 250

Also at the begins and ends, thats where y = 0, the 2 points are separated by 100 ft. So let the begin at -50 ft and the end at 50ft. We have

-a(\pm 50)^2 + 250 = 0

-a2500 = -250

a = 250/2500 = 0.1

Therefore, the model quadratic equation of our path would be

y = -0.1x^2 + 250 ft

Write an equation to show the height of the two buildings are equal to each other. Then solve for x. Show all your steps when so
Ierofanga [76]

Answer:

X = 108.

Step-by-step explanation:

Heights are equal, So equation will be,

4 + 3 \sqrt{x - 8}  = 34

So, solving the eq.

Subtract 4 from both sides ,

3 \sqrt{x - 8}  = 30

Divide 3 to both sides,

\sqrt{x - 8}  = 10

Squaring both sides,

x - 8 = 100

Add 8 to both sides,

x = 108
