It will reach 80 feet for the second time after 5 seconds.
We set the equation equal to 80 feet:
80= -16t² + 96t
When solving quadratics, we want it equal to 0, so we subtract 80 from both sides:
80-80= -16t² + 96t - 80
0= -16t² + 96t - 80
We use the quadratic formula to solve:
Answer:
third option
Step-by-step explanation:
<u>angle 1</u>
measure of angle 1 is diagonal to 45, theyre congruent angles
so measure of angle 1 is 45
<u>angle 2</u>
the sum of a triangle is 180 degrees
so for measure 2, we add 45 + 59 and we get 104. then we do 180 - 104 and we get 76
so the measure of angle 2 is 76
<u>angle 3</u>
since we know that the measure for angle 1 is 45, we can also solve for the measure of angle 3
to find angle 3, we do 55 + 45 and we get 100
and then you do 180 - 100 and you get 80
so the measure of angle 3 is 80
The answer is C. The y intercept because a constant simply means a number without a variable accompanying it. The y intercept its the only number without a coefficient.
Answer:
x 
3
Step-by-step explanation:
if x = 3 then the rational expression 4 / (x - 3) is undefined
because we get 4/0 = undefined .
