Enjoy borrowed $1500 from her parents for car repairs. She plans to take 10% of her 450 weekly income to pay them back. At the i
1 answer:
10% of 450 dollars is equal to 0.1×450 or $45.
If she pays her parents $45 each week, it will take her 1500 ÷ 45 weeks to pay them back.
1500 ÷ 45 = 33
Even though this would ordinarily be rounded down to 33, Her loan would not be paid off at the end of 33 weeks, so it must be rounded up to 34 weeks.
It will take Enjoy 34 weeks to pay off the loan.

The horizontal distance from the firefighter at which the maximum height of water occurs is 10.83m
<u>Explanation:</u>
Given:
h(x) = -0.026x² + 0.563x + 3
where,
h(x) is the height of the water
Initial speed, u = 14m/s
angle, θ = 30°
(a)
Horizontal distance = ?
h(x) = ax² + bx + c
the vertex is found at x = -b/2a
where,
x = distance to the maximum height
As compared to the equation given:
a = -0.026
b = 0.563
Thus,
Therefore, horizontal distance from the firefighter at which the maximum height of water occurs is 10.83m
