Yes, your answer is correct.
Answer:
y = -1/8 x² + 5
Step-by-step explanation:
Parabola opens vertically and vertex (h,k) = (0,5), pass point (4,3)
basic formula: y = a(x - h)² + k
y = a (x-0)² + 5
y = ax² + 5 pass (4,3)
3 = 16a + 5
a = (3-5)/16 = -1/8
equation: y = -1/8 x² + 5
check: pass another point (-4,3)
-1/8 * (-4)² + 5 = -2 + 5 = 3
H= ut -16 t^2
h = 144(2) - 16 (4)
= 288 - 64 = 224
What is the length of BD given that figures ABCD is a rectangle and AC=26
Either 1/10 or 10%
