Answer:
<h3>
She reaches her maximum height after 0.25 seconds</h3>
Step-by-step explanation:
The question is not properly structured and the equation is also incorrect. Here is the correct question.
You and some friends went to a haunted house on Halloween. The mummy scared one friend so much that she jumped into the air! The equation h= -4t²+ 2t models her jump where h is her jumps height in feet t seconds after the mummy scares her. When did she reach her maximum.
Give the equation h= -4t²+ 2t that models my friend jump where h is her jumps height in feet t seconds, At maximum height, her velocity will be zero i.e
Vmax = 0m/s
Velocity is the rate of change in distance of a body i.e V = dh/dt
Given h= -4t²+ 2t
V = dh/dt = -8t+2
Since v = 0m/s
0 = -8t+2
-8t = -2
t = -2/-8
t = 0.25 secs
She reaches her maximum height after 0.25 seconds

Answer:
<em>31 foot</em>
Step-by-step explanation:
Radius of the circular path = 15 feet
Angle of horse travel on a circular path = radians = Central Angle
Central angle = degrees = 120°
Distance travelled by the carousel horse on the circular path over an angle of = Arc length
We can use the formula below to calculate arc length;
°
Arc length =
Arc length = 31.4 foot
Arc length (rounded to the nearest foot) = 31 foot
First subtract the difference of the points from total points:
56-36 = 20
Now divide 20 points by 2 teams:
20/2 = 10
Now add 36 to 10: 36 + 10 = 46
The final score was 46 to 10
Chicago got 46 points New England got 10 points.
The answer is 3.12 thank me later ;)
