Step-by-step explanation:
Answer:
See below
Step-by-step explanation:
y = -6x^2 + 24x-100
solve for 'x'
y + 100 = -6x^2 + 24x = -6(x^2-4x) complete the square for x
(y+100) /(-6 ) = (x-2)^2 -4 add 4 to both sides
(y+100)/(-6) +4 = (x-2)^2 sqrt both sides
sqrt [ ( y+100)/(-6) + 4 ] + 2 = x change x and y
y = ± sqrt [ (x+100)/(-6) + 4 ] + 2 simplify (if needed)
<u>y = ± sqrt( -x/6 -12.666) + 2 </u>
Let s = shadow we are looking for.
40/200 = 25/s
Solve for s.
200(25) = 40s
5000 = 40s
5000/40 = s
125 = s
The answer is 125 feet.
-4 first we rearrange the question x-2y=8
x-2y=8
-2y=-x+8
y=1/2x-4 (divide by -2 everywhere)
-4 is the y intercept.
