Answer:
-5
Step-by-step explanation:
"r(s(-2))" is a composition of functions. To evaluate this, we need to plug in "-2" into the function S(x) and then take that value and further plug it into R(x).
First, s(-2):
Now, we take the value (-4) and put it into R(x) to get our final answer:
Hence, r(s(-2)) = -5

This is about understanding the meaning of a rectangle and parallelogram.
<u><em>Option A is the correct definition.</em></u>
<u><em /></u>
We are given the 2 statements as;
1) A rectangle is a parallelogram with 4 right angles
2) A rectangle is a parallelogram
- Let us define a rectangle and parallelogram;
- A rectangle is defined as a quadrilateral with four right angles. This means all the angles are equal. It also has 4 sides with the length of opposite sides being parallel to each other.
- A parallelogram is defined as a quadrilateral that has two pairs of parallel sides with the opposite sides of such parallelogram having equal length and the opposite angles being equal.
- Option A; This is correct because the reverse statement is that; A parallelogram is a rectangle with 4 right angles, This is possible because the only condition where a parallelogram is a rectangle is when it has 4 right angles.
- Option B; This is wrong because a rectangle is not a parallelogram.
- Option C; This is wrong because not all parallelograms are rectangles.
- Option D; This is wrong because a rectangle must have 4 right angles

Cos A = 3/4.24 and cos B = 3/4.24 also.
The ratio of cos A to cos B is thus 3/3, or 1 (answer)
V = π r^2 (h/3)
(Volume equals pi r squared, h over 3)
Diameter is 4, so the radius is half of that = 2
Plug in the numbers
V = π (2^2) (16/3)
V = π (4) (5.333)
V = 3.14 x 4 = 12.566
V = 12.566 x 5.333
V = 67.014
