216 times smaller, 21600%, the cross section is a rectangle or square
Answer:
B
Step-by-step explanation:
Because there are 2 different y values for the x value of 5. All x values can only have 1 y value.
For B, there are y points on the x value of 5, so this fails the vertical line test, and is therefore not a function
Answer:

Step-by-step explanation:
Using the product to sum formula
sinxcosy =
[ sin(x + y) + sin(x - y) ] , then
2sinxcosy = sin(x + y) + sin(x - y)
Given
2sin75°cos15° ← with x = 75 and y = 15 , then
= sin(75 + 15) + sin(75 - 15)
= sin90° + sin60°
= 1 + 
= 
Answer: 7.88 currency units
Step-by-step explanation:
