Answer:
Sal's Sandwich Shop sells wraps and sandwiches as part of its lunch specials. The profit on every sandwich is $2 and the profit on every wrap is $3. Sal made a profit of $1,470 from lunch specials last month. The equation 2x + 3y = 1,470 represents Sal's profits last month, where x is the number of sandwich lunch specials sold and y is the number of wrap lunch specials sold.
5. Suppose Sal's total profit on lunch specials for the next month is $1,593. The profit amounts are the same: $2 for each sandwich and $3 for each wrap. In a paragraph of at least three complete sentences, explain how the graphs of the functions for the two months are similar and how they are different.
6. Below is a graph that represents the total profits for a third month. Write the equation of the line that represents this graph. Show your work or explain how you determined the equations.

Answer:
L.S = R.S ⇒ Proved down
Step-by-step explanation:
Let us revise some rules in trigonometry
- sin²α + cos²α = 1
- sin2α = 2 sin α cosα
- cscα = 1/sinα
To solve the question let us find the simplest form of the right side and the left side, then show that they are equal
∵ L.S = csc2α + 1
→ By using the 3rd rule above
∴ L.S = 
+ 1
→ Change 1 to 
∴ L.S = +
→ The denominators are equal, then add the numerators
∴ L.S = 
∵ R. S = 
∵ (sinα + cosα)² = sin²α + 2 sinα cosα + cos²α
∴ (sinα + cosα)² = sin²α + cos²α + 2 sinα cosα
→ By using the 1st rule above, equate sin²α + cos²α by 1
∴ (sinα + cosα)² = 1 + 2 sinα cosα
→ By using the 2nd rule above, equate 2 sinα cosα by sin2α
∴ (sinα + cosα)² = 1 + sin2α
→ Substitute it in the R.S above
∴ R. S =
∵ L.S = R.S
∴ csc 2α + 1 =
Answer:
<em>$2,025.78 </em>
Step-by-step explanation:
I = Prt ⇒ P = 
2.25% = 0.0225
P = 45.58 ÷ ( 0.0225 × 1 ) ≈ <em>$2,025.78</em>
Answer: 2w
Step-by-step explanation: if the garden is shaped like a square, then all the sides are equal,
length = breadth, and the Area of a square or rectangle is the length multiplied by the breadth
and to find the length and breadth, we find the square root of the area
The area is 4w2
We know that 4 is the perfect square of 2, making 2 the square root of 4
And w2 is the square of w
This is elementary algebra, a x a = a2
b x b = b2, w x w = w2
So adding both together, the square root of 4w2 = 2w
