Answer:
87.5
Step-by-step explanation:
By completing the square,
y
=-14x^2+70x
=-14(x^2-5x)
=-14(x-5/2)^2+175/2
the max. height=175/2
i.e. 87.5
Sorry, but you did not ask any valid question, so I cannot help you figure out an answer.
<span>|3x| = 12 actually represents two equations: 3x = 12 and -3x = 12.
Thus, the solutions are {-4, 4).</span>
Rearrange the equation so it looks like y=mx+b
y=
+5
m is the slope
m=
Answer:
7. volume is raised to the third (a³) power.
8.≈ 5.64ft
Step-by-step explanation:
volume is always raised to the third power which also indicates that the object/shape is cubed.
height= 4ft
volume= 100ft³
then, multiply both the height and volume together.
4ft × 100ft³
≈ 5.64ft
