Answer:
A. The area is 
B. She needs to cover 1661.9 square feet of tiles for the base of the swimming pool
Step-by-step explanation:
Question A:
Let us assume that the leash is pegged to the ground using a stake. as a result, the dog can move around the stake. The path that the motion of the dog would trace is a circle, and the radius of the circle will be the length of the leash.
Since we know this, we can easily find the area of the circle using 
Area of the circle = 
Question B
Dulce wants to cover the whole surface area of the floor of the circular swimming pool with tiles.
We already know that the swimming pool is circular, hence, the surface area of the base of the swimming pool will be the same as the area of a circle, with the same radius.
The area of the circle can be calculated using
Area of circle = 
Given Data:
Depreciation rate per year 1 / 5-year useful life = 20%
Salvage value = $4700
Purchase cost = $59000
Step 1: Depreciable asset cost = Purchase cost of – estimated salvage value
Depreciable asset cost = $59,000 – $4,700
= $54,300
Step 2: Annual depreciation = <span>depreciation rate x depreciable asset cost
</span>Annual depreciation = 20% x $59,000
= $11,800
Therefore, <span>depreciation expense recorded for the van during the first year ended December 31 is </span>$11,800.
Answer:
12.5 hours.
Step-by-step explanation:
First man walks in one hour = 6 miles
Second man walks in one hour = 10 miles
Since they are walking in opposite direction so distance between them after 1 hour = 6 + 10 = 16 miles
Since after one hour they are 16 miles apart from each other
Therefore, they will be 200 miles apart from their starting point
= 200 ÷ 16 = 12.5 hours.
After 12.5 hours they would be 200 miles apart.
Answer:
4
Step-by-step explanation:
The derivative of a 5th-degree polynomial is a 4th-degree polynomial, so will have at most 4 real zeros. The zeros of the derivative correspond to the turning points of the function.
