Answer:
Anna's number could be 5 and it could be 6.
Step-by-step explanation:
Let Anna's number be represented by x.
If Bill squared her number followed by subtracting 11 times her number, and adding 4, then he would get -26.
This implies that:

This is a quadratic equation and we can solve for x by factorization.

Vertical angles measure the same
Answer:
It will take 22 seconds for the thermometer to hit the ground.
Step-by-step explanation:
A thermometer falls from a weather balloon at a height of 7,744 ft.
This means that the initial height is of 7744ft.
h(t) = -16t2 + initial height
So

How many seconds will it take for the thermometer to hit the ground?
This is t for which
. So





It will take 22 seconds for the thermometer to hit the ground.
