Answer:
y = -0.005x² + 50
Step-by-step explanation:
The diameter is 200 feet, so the parabola has roots at (-100, 0) and (100, 0). The maximum height is 50, so the vertex of the parabola is at (0, 50).
Using vertex form of a parabola:
y = a (x − h)² + k
y = a (x − 0)² + 50
y = ax² + 50
Plugging in either root:
0 = a (100)² + 50
a = -0.005
y = -0.005x² + 50
X+ 77.5 because if you subtract 25 from 180 you get 155. Then divide 155 by 2 and you get 77.5
Answer:
Each gardner will get <u>1/16</u> of a pile of pine needles.
Step-by-step explanation:
1/2 ÷ 8
<em>*Switch the division to multiplication and flip the 8 (or 8/1) upside-down.</em>
= 1/2 · 1/8
= 1/16
B, Only(-3,3)
-3(-4)-4=6
8=6
This ordered pair does not work, as 8 does not equal 6.
-3(-3)-3=6
6=6
This ordered pair works!
Assuming all the hours are done within the same week, then
normal pay (assuming 40 hours per week) = 40*12 = $480
Overtime pay = $300 = x hours * (12*1.5)
Solve for x:
x=300/(12*1.5) = 300/18 = 16 2/3 hours
