**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:**

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**
