Answer:
2 1/4
Step-by-step explanation:
- 5 1/4 - ( - 7 1/2)
Subtracting a negative is like adding
- 5 1/4 + 7 1/2
Get a common denominator of 4
-5 1/4 + 7 2/4
Subtract
7 2/4 - 5 1/4
2 1/4
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:
the distance between the two points =is 13
It would be 9.
the original equation y=x^2 - 2x + 3 is multiplied by 3, as the scale factor is 3.
