Answer:

16

Step-by-step explanation:

6x-7=2x+3 Cause point M is the midpoint, so JM and MK have to be equal.

4x=10

x=2.5

JM=15-7=8 and MK=5+3=8

8+8=16

If 2x − 4(x + 1) = −12, evaluate x2 − 1.
Vlad [161]
2x-4(x+1)=-13
1) we solve this equation:
2x-4(x+1)=-12
2x-4x-4=-12
-2x=-12+4
-2x=-8
x=-8/-2
x=4

2) we evalute x²-1
x²-1=4²-1=16-1=15

A ball is thrown vertically upward. After t seconds, its height h (in feet) is given by the function h(t)=72t-16t^2. What is the
irakobra [83]

Answer:

The maximum height that the ball will reach is 81 ft

Step-by-step explanation:

Note that the tray of the ball is given by the equation of a parabola of negative main coefficient. Then, the maximum value for a parabola is at its vertex.

For an equation of the form

at ^ 2 + bt + c

So

the t coordinate of the vertice is:

t =-\frac{b}{2a}

In this case the equation is:

h(t)=72t-16t^2

So

a=-16\\b=72\\c=0

Therefore

t =-\frac{72}{2(-16)}

t=2.25\ s

Finally the maximum height that the ball will reach is

h(2.25)=72(2.25)-16(2.25)^2

h=81\ ft
