The surface area not including the top of the pool would be 748 ft(not sure if the teacher want you to add square to the end of it or not) .so 12*5 is 60 ,*2 =120. 24*5 =120. 120*2= 240. 24*12=288. so 288+240+120=748 ft(this would be the surface area of the pool.so if you need the volume of concrete needed to make the pool times the needed with of the concrete by the area ∆make sure if the needed thickness needed is in inches turn the area from feet to inches by multiplying it by 12 )
Answer:
the last one
Step-by-step explanation:
12+(16/4+2)2
12+(4+2)2
12+6*2

The index of the refraction is 0.898 and the index of the refraction is less than one which is unreasonable because the speed of the light can't be more than c.
<h3>What is refraction?</h3>
The phenomenon bending of a wave as it crosses from one medium to another is said to be refraction. The difference in density is the cause of the bending.
Refraction is a term that is used to describe the phenomenon of refraction."The change in direction of a wave traveling through one medium to another is known as refraction."
From the Snell's law:
nsinФ = n'sin∅
We have n' = 1.33, ∅ = 10.0°, Ф = 14.9°
nsin110.0° = 1.33×sin14.9°
n = 0.898
Because the speed of light cannot be greater than c, the index of refraction is less than one, which is illogical.
It is illogical to assume that the angle of refraction is excessively large in relation to the angle of incidence.
Thus, the index of the refraction is 0.898 and the index of the refraction is less than one which is unreasonable because the speed of the light can't be more than c.

Answer:
the length of side AC is 4 units
Completed question;
What is the length of side AC as shown on the coordinate plane? With coordinates (-2,1) (-2,-3)
Step-by-step explanation:
Given;
A = (-2,1)
B = (-2,-3)
The length L between two points with coordinates (x1,y1) and (x2,y2) can be written as;
L = √((x2 - x1)^2 + (y2 - y1)^2)
Substituting the given values;
L = √((-2--2)^2 + (-3 -1)^2)
L = √(0 + 16)
L = √16
L = 4
the length of side AC is 4 units
