The answer is D.
the base of the pyramid is lxh which is .75 x .75 = 0.5625
Each of the sides are triangles which are 1/2 bxh which equals .6/2 = .3
there is 4 triangular sides so .3 x 4 = 1.2
and 1.2 + 0.5625 = 1.7625.
The owner loses $60 because if the man stole $100 and gave the owner $70 that would mean that he has to lose $30 making the owner lose $60.
Answer:
We'll use the following identities:
r = √(x2 + y2), from which we also have r2 = x2 + y2
y = r*sinθ
First, let's re-write your equation:
r = 8*sin(θ). Multiply both sides by r:
r2 = 8r sin(θ)
Now, we'll use substitute using the identities:
x2 + y2 = 8y
Re-arrange and complete the square:
x2 + y2 - 8y = 0
x2 + (y-4)2 - 16 = 0
x2 + (y-4)2 = 16
This represents a circle with center (0,4), and radius 4.

Problem 16
<h3>Answer: i</h3>
------------------
Work Shown:
The exponent 41 divided by 4 leads to
41/4 = 10 remainder 1
The "remainder 1" means that
i^(41) = i^1 = i
The reason why I divided by 4 is because the pattern shown below
i^1 = i
i^2 = -1
i^3 = -i
i^4 = 1
repeats itself over and over. So this is a block of four items repeated forever.
=====================================
Problem 18
<h3>Answer: 1</h3>
------------------
Work Shown:
Divide 3136 over 4 to get
3136/4 = 784 remainder 0
Therefore,
i^3136 = i^0 = 1
=====================================
Problem 20
<h3>Answer: i</h3>
------------------
Work Shown:
Combine i^6*i^7 into i^13. We add the exponents here
Now divide by 4 to find the remainder
13/4 = 3 remainder 1
So, i^13 = i^1 = i
5. Area = 2 unit * 7 units = 14 squared units
6. Area = 3 units * 4 units = 12 square units
7 Area = Area of big rectangle + Area of small rectangle = 42 + 15 = 57
8. Area = 1 * 5 + 2*8 = 5 + 16 = 21 square units
Hope that helps!
