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 = 
Answer:
56 + 23 + (-5)
you want to expand the bracket first
23 + (-5)
23-5 = 18
56 + 18 = 74
a) 74
6 + 24 + (-2)
24 - 2= 22
6 + 22 = 28
b) 28
3 + 7 + (-42)
7 - 42 = -35
3 - 35 = -32
c)-32
( 8 + 1 ) + (-3)
+(-3) = -3
9 - 3 = 6
d)6
( 7 + 10 ) + ( 3 + 1 )
17 + 4 = 21
e)21
59 + 2+ (-6)
2+(-6) = 2-6 = -4
59-4
55
f)55
41 + ( -89)
41 - 89
= - 48
g)-48
( - 13) + 33
-13+33
= 20
h) 20
A Prime Number is a number that you can only get by multiplying it by itself and 1.
A Composite Number is a number that has more than one way to get the the solution.
Examples:
Prime: 17. only way to get it is 1×17
Composite: 15. 1×15 obviously. also 3×5
Answer:
√34
Step-by-step explanation:
Use distance formula: 
d = 
= √34
Answer:
Step-by-step explanation:
The foci are horizontally aligned, so the hyperbola is horizontal. The center is midway between foci, at (0,0).
y²/a² - x²/b² = 1
a² + b² = 5²
Directrices: x=± a²/5 = ±2
a=√10
b = √15
y²/10 - x²/15 = 1
