Answer:C
Step-by-step explanation:
9×4=36
2×.5×4×3=12
36+12=48
Answer:
3.33%
Step-by-step explanation:
9.90/300=0.033
assuming that 0 apples costs 0 dollars
and 16 apples costs $8
so we have the points
(0,0) and (16,8) in form (x,y)
graph below
Answer:
4 ft
7.2 ft
20 ft
Step-by-step explanation:
When the balloon is shot, x = 0.
y = -0.05(0)² + 0.8(0) + 4
y = 4
The balloon reaches the highest point at the vertex of the parabola.
x = -b / 2a
x = -0.8 / (2 × -0.05)
x = 8
y = -0.05(8)² + 0.8(8) + 4
y = 7.2
When the balloon lands, y = 0.
0 = -0.05x² + 0.8x + 4
0 = x² − 16x − 80
0 = (x + 4) (x − 20)
x = -4 or 20
Since x > 0, x = 20.
It is 1.55 times the value of the second number.
