Answer:
D. 16 ft
Step-by-step explanation:
h = √20² - (24/2)² = √400-144 = √256 = 16
s1 = 3
s2 = 3×2 = 6
s3 = 6×2 = 12
s4 = 12×2 = 24
s5 = 24×2 = 48
sn = sn-1 × 2 = s1 × 2^(n-1)
s17 = 3 × 2¹⁶ = 3 × 65,536 = 196,608
ok I will help
slope = (y2-y1)/(x2-x1)
m = (-3-6)/(4--2)
= -9/6
=-3/2
y -y1 = m(x-x1)
y-6 =-3/2 (x--2)
y-6 =-3/2 (x+2)
y-6 =-3/2 x -3
add 6
y = -3/2 x +3
