Answer:

h=25

Step-by-step explanation:

From the question we are told that:

Velocity v=40fts

The height h function

 \large h=-16t^2+40t

Generally time t is mathematically given by

 h'=-32t+40

 -32t+40=0

 t=\frac{40}{32}

 t=1.25

Therefore  the ball's maximum height is given as

  \large h=-16(1.25)^2+40(1.25)

 \large h=-16(1.25)^2+40(1.25)

 h=25

kirza4 [7]

MKL = 83, JKL = 127, JKM = 9x - 10        <em>given</em>

JKL + MKL = JKM                                    <em>angle addition postulate</em>

127 +  83  = 9x - 10                                 <em>substitution</em>

       210   = 9x - 10                                  <em>simplify (add like terms)</em>

       220  = 9x                                          <em>addition property of equality</em>

        \frac{220}{9} = x

First, you have to do some factorization

60 = {1,2,3,4,5,6,10,12,15,20,30,60}
72 = {1,2,3,4,6,8,9,12,18,24,36,72}

the GCF is 12

now we find the number that you multiply by 12 to get 60 and another number to get 72.

12 x 5 = 60
12 x 6 = 72

now we notice if you add 60 + 72, we can now tell that it also equals (12)(5)+(12)(6)= 12(5+6)
