Answer: time to reach maximum height = 605
Step-by-step explanation:
The expression that relates height with time is
M(d)=-0.123x^2+148.83x-21.07
Where time = x
d = height
The expression is a quadratic equation. If height of the object is plotted against time, the resulting graph is a parabola whose vertex is equal to the maximum height attained by the object. The time, x corresponding to the vertex is the time for it to reach maximum height.
To find x,
x = -b/2a
Where a= 0.123
b = 148.83
x = - 148.83 / -2 × -0.123
x = -148.83 / -0.246
= 605
Substituting x = 605 in the equation,
M(d)=-0.123x^2+148.83x-21.07
d = -0.123 × 605^2 + 148.83×605
= - 45021.075+ 90042.15
= 45020.4
Approximately 45000 feet
<span> What we are going to do for this case is find the cost for each case:
Cost to run the car before the mechanic worked on it:
</span>

<span> Cost to run the car after the mechanic worked on it:
</span>

<span>
The difference between both cases is:
</span>

<span>
Answer: It cost to run the car after the mechanic worked on it 0.01 $ / mile less than before the mechanic worked on it.</span>
Answer :
Measure of RS = 116
x=24
Explanation:
Since the RS and TU are congruent, the arc degrees are too because they are in the same circle.

Answer:
$52000.00
Step-by-step explanation:
formula= principal (1+(rate÷100))^years
500 (1+(4÷100))^1
500 (1+0.04)^1
500 (1.04)
520
$520.00
100 cents = $1
520×100
52000 cents
