=> [1 - 2(CosASinA)²]² - 2(CosASinA)⁴
//Remember: Sin2A = 2SinA CosA => SinACosA = 1/2Sin2A

You can buy 5 cans for green beans at the Village Market for $2.70. You can buy 10
of the same cans of beans at Sam's Club for $6.50. Which place is the better buy?
Answer:
Village Market
Step-by-step explanation:
for this question we need to find the unit rate (the rate for one of something).
in this case, we need to find the cost of one can at each store so we can
easily compare the cost to see which one is cheaper
it would be (total cost)/(total number of cans)
Village Market = $2.7/5 = .54 cents per can
Sam's Club = $6.5/10 = .65 cents per can
Since Village Market has a cheaper price per can, it is the better buy.
Answer:
Village Market
Step-by-step explanation:
10 cans at the Village Market is = to $5.40.
But at Sam's Club 10 cans cost $6.50 witch is $1.10 more money your paying when u can save it.

In other words, for each x-value, there is only one corresponding y-value.
For the equation x2 + y2 = 10, find the y-value for a given x-value.
Let x = 1.
Since (-3) · (-3) = 9 and 3 · 3 = 9, there are two y-values for x = 1.

The triangles are not similar.
What is similarity in triangles?Two triangles are similar if they have the same ratio of corresponding sides and equal pair of corresponding angles.
The Given triangle ZXB and DZN are not similar
Because,
XZ/DZ =XB/DN ≠ ZB /BN
XZ/DZ = 1/2
XB/DN = 1/2
ZB /BN = 1/3
Hence, the triangles are not similar.

Employees of landscaping companies built a retaining wall. They used brick to make the top 2/3 of the wall.
250 POINTS
Part A: What is the height of the brick proportion of the wall? Write an equation
Part B: Estimate the area of the whole retaining wall. A= LxW
For part c you need a equation
Part C: What is the area of the whole retaining wall? Write an equation to show your work. Compare your answer to your estimate to see whether your answer is reasonable
Answer with Step-by-step explanation:
a) 2 3/4 ÷ 3 = 11/12 feet
11/12 + 11/12 = 1 5/6
Or, you could write an algebraic equation:
2 3/4 ÷ 3 = x. (3x = 2 3/4)
x = 11/12
The height of the brick proportion of the wall is 1 5/6
b)
You know that 8 x 2 is 16. Well, you already know that the whole total of fractions, multiplied together, would probably be less that 1 and less than 1/2.
So, your rounded answer should be 16. Or 16 1/2
c)
Area = 8 1/2 x 2 3/4.
Use Distributive Property to solve the area.
(8 x 2) + (3/4 x 1/2) = x
8 x 2 = 16
3/4 x 1/2 = 3/8
16 + 3/8 = 16 3/8
x = 16 3/8
I think my answer is reasonable because I estimated 16, and 1/2. 3/8 is close to 1/2. That's why my answer is reasonable.
