Answer:
A: y = (x − 4)^2 − 4
Step-by-step explanation:
vertex=(4.-4)
A: y = (x − 4)^2 − 4
y=x^2-8x+16-4
y=x^2-8x+12 (a=1,b=-8,c=12)
the y intercept is (0,12)
vertex ( h, k)
h=-b/2a ⇒ h=-(-8)/2=4
plug the value of h in the equation y=x^2-8x+12
k=4²-8(4)+12
k=16-32+12
k=-4
v(4,-4)
The equation for the shadow length L.
Is L=0.72*h
Therefore at 123 feet the shadow length would be 88.56 feet
A. Is the right answer I think I have e does this one before back in5th so I’m sure it’s A.
Answer:
y=5/3x .This is the answer
