Answer:
It takes 1.323 seconds for the ball to fall by 36 feet
Step-by-step explanation:
The height of the ball dropped from a height of 64 ft is modeled by the equation:
h(t) = -16t² + 64 where t is the time in seconds.
To find the time it takes to fall 36 ft, we substitute h(t) too be 36 ft and then solve the resulting quadratic function.
Substituting h(t) to be 36 ft:
36 = -16t² + 64
multiply through by -1
-36 = 16t² - 64
add 36 to both sides
16t² -64 + 36 = -36 + 36
16t² - 28 = 0
add 28 to both sides
16t² - 28 + 28 = 0 +28
16t² = 28
Divide both sides by 28
16t²/16 = 28/16
t² = 1.75
Find squre root of both sides
√t² = √1.75
t = 1.323 seconds
It takes 1.323 seconds for the ball to fall by 36 feet
Answer:
about $62.18
Step-by-step explanation:
Just find the amount of the percentage so,
7.5% of 829 = 62.175
So the tax for the phone is 62.175,
Now round it to the nearest tenth since you can't pay 62.175 because you can't pay half a cent.
62.175 = about $62.18
Answer: Can u flip it its upside down and I have no Idea what the answer is.
Step-by-step explanation:
Divide by three on both sides then end up with x+2=3 then x=1
Answer:
Step-by-step explanation:
To see if these have the same function plug the x from the table into the equation given and see if it gives the same result as the table. For example y=-(-4)+3
y=4+3
y=7
This was different from what the table got so they are not the same function
