Answer:
Step-by-step explanation:
<u>Note</u>: <em>It seems the question is wrong when it states the relationship of distance. If d is the distance from the ground, at t = 0, we get d = 0 too which means with no time spent, Math Man hits the ground.</em>

It assumed d = t²*0.25 is the distance from the top of the building.
We know the height of the building is 500 meters.
We need to find the value of t, when d = 500 m:
- 0.25t² = 500
- t² = 500/0.25
- t² = 2000
- t = √2000
- t = 44.7 units of time (assumed seconds)
Answer:
The amount of money in the account in addition to that earned from mowing lawns.
Step-by-step explanation:
125 is the amount in the account when 0 weeks are spent mowing lawns. Presumably, it is the initial value of the account before the first lawn money is added.

The correct selling price is about $20, and the likely mistake was the manager multiplied the $12 by .67 (the 67%), got about 8, and took that as the price instead of adding it to the original 12, which is what they were supposed to do.
Answer:
Step-by-step explanation:
Just comparing the given y= +(x-2)^2 + 4 to
y = (x - h)^2 + k
reveals that the vertex is at (h, k): (2, 4) and that the graph opens up.
The correct graph is the one in the upper left hand area of the illustration.
Answer:
-1
Step-by-step explanation:
The total number of minus signs is odd, so the product is negative.
(-1)^39 = -(1^39) = -1
