Answer:

22 seconds

Step-by-step explanation:

h(t) = -16t2 + 704t

The maximum will occur at the axis of symmetry.

We can find the axis of symmetry at

h = -b/2a

where at^2 +bt+c

 so a = -16 and b = 704

h = -704/(2*-16)

h= -704/-32

  = 22

I dont know functions
Irina-Kira [14]

Answer:

6, -8

Step-by-step explanation:

You need to find out the possible values of which X cannot equal

In fractions the only way that's possible is if the denominator= 0

Because everything in the denominator is being mulitplied this is pretty simple

We need either parantheses to equal 0

so we take them and solve for 0

we have

x-6= 0

x=6

x+8=0

x= -8

What is the missing side length?<br> (Use Pythagorean Theorem)
Vedmedyk [2.9K]

Answer:

20 units

Step-by-step explanation:

The Pythagorean Theorem states that:

                                a^{2} + b^{2} = c^{2} \\

Now we can insert values into the equation.

                                      a = 15\\b = b\\c = 25\\

Now we can plug these ☝ values into the Pythagorean Theorem:

                                  15^{2} + b^{2} = 25^{2}\\

After we solve for b we get:

b^{2} = 400\\b = 20
