Answer:
h = 110.24 m
Step-by-step explanation:
It is given that,
A rock is thrown up from the ground at a velocity of 84 feet per second. The formula
gives the rock's height in feet after t second.
We need to find the maximum height of the rock. For maximum height put 
So,

Put t = 2.62 s in the equation of height. So,

So, the maximum height of the rock is 110.24 m.
Answer:
71%
Step-by-step explanation:
Firstly, 200 - 58 = 142
Next, 142 / 200 = 0.71
0.71 x 100 = 71%
Answer:
441 miles
Step-by-step explanation:
Write and solve an inquality to answer this question:
($24.95/day)(2 days) + ($0.34/mile)x ≤ $200
The first term becomes $49.30; the second term $0.34x; their sum must be ≤ $200.
More concisely, 49.30 + 0.34x ≤ 200.
Isolate x by subtracting 49.30 from both sides:
0.34x ≤ 150.10.
Divide both sides by 0.34:
x ≤ 150.10/0.34, or 441.47 miles. You must round this off to the nearest whole mile, which would be 441 miles.
Since 1 Euro is 1.321 in American money you must convert the value to $200
Divide 200 by 1.321
you get
151.40 in Euros
