Between A and B = 12 is A.
Answer:
(A) Is right
Step-by-step explanation:

put X= -2. in y = X+3
to get y 's value
Y = -2+3
= 1
therefore, your solution is ( -2,1)
Answer:
Therefore the height of the water in the pool changes at the rate of
feet per minute.
Step-by-step explanation:
Given that the shape of swimming pool is right circular cylinder.
The rate of water pouring in the pool = 3 cubic feet per minute.
It means the rate of change of volume is 3 cubic feet per minute.
cubic feet per minute.
When the volume of the swimming pool changed it means the height of the water level of the pool change and the radius of the swimming pool remains constant.
Let the height of the pool be h.
The volume of the pool is =
cubic feet
cubic feet
Therefore,
v 
Differentiating with respect to t

Putting 



The change of height of the pool does not depend on the depth of the pool.
Therefore the rate of change of height of the water in the pool is
feet per minute.

Answer:
62 1/2 square feet
Step-by-step explanation:
The total area is the area of the central square plus the area of the four triangles.
The area formula for a square is ...
A = s² . . . . for side length s
The area formula for a triangle is ...
A = 1/2bh . . . . for base b and height h
Here, we have a square with side lengths of 5 m, and triangles with a base of 5 m and a height of 3 3/4 m. Then the area of the square plus the area of 4 triangles is ...
A = (5 ft)² + 4×(1/2)(5 ft)(3 3/4 ft) = 25 ft² +37 1/2 ft²
A = 62 1/2 ft²
