The maximum height of the object is 82.7034 from the ground
<h3>What is Velocity ?</h3>
Velocity is the measure of movement of an object with respect to time.
It is measured in m/sec
h = -4.9t²+21.6t +58.9
dh/dt = -9.8t +21.6
At maximum height , velocity = 0
therefore
-9.8t +21.6 = 0
9.8t = 21.6
t = 2.204 sec
h = -4.9 (2.204)²+ 21.6 * 2.204 +58.9
h = -23.803 +47.606 +58.9
h = 82.7034 from the ground
h = 23.80 from the point it is launched.
The maximum height of the object is 82.7034 from the ground

Answer:
One order of fries costs 2
Step-by-step explanation:
She got 4.25 + two fries on Monday
She got 6.75 + one fries on Tuesday
Since she spends the same amount of money on lunch every day, both of the money that is spent must be equal.
Let f represent the cost of one order of fries, then equations can be written as follows:
4.25 + 2f (1)
6.25 + f (2)
Since both is equal:
→ 4.25 + 2f = 6.25 + f
→ f = 2
