Angles 6 and 7 are vertical angles, not alternate interior.

The same applies to angles 4 and 1, and angles 5 and 8 as well.

Any time you have two lines cross to form an X shape, the angles that are opposite one another are considered vertical angles and are always congruent.

The values you have typed into the boxes are all correct. The other drop-down choices are correct as well. Nice work.

Your mistakes are that you are confusing vertical angles with alternate-interior angles. Angles 6 and 7 for example are vertical angles while angles 3 and 6 are alternate-interior angles.

The height in feet above the water of a diver can be modeled by ℎ() = −16*2 − 16 + 192, where t is the time in seconds after the

Maurinko [17]

h(t) is the height of the diver in feet above the water

Now it asks about the time at which diver reaches the water

When diver reaches the water , the height of diver from water should be zero

So we plug h(t) =0

$-16t^2 -16 t +192 =0$

divide whole equation by -16

$t^2 +t -12 =0$

we can now factor the quadratic equation

So we get

(t+4)(t-3) =0

plug each factor equal to zero and solve for t

t+4 =0 and t-3 =0

So t=-4 and t=3

Now time cannot be negative , So t=3

So time = 3 seconds

It takes 3 seconds for the diver to reach the water

Which graph shows a function whose inverse is also a function?

tangare [24]

Answer:

To do this, you imagine a vertical (up and down) line moving across your graph from left to right. It should only be touching the line at one point at a time. If it is touching more than one point on the line at a time, the line is not a valid function. The first line and its inverse both pass the test.
