Answer:
1. y = 14.718
2. ??
3. y = 39.794°
Step-by-step explanation:
<em>HINT the side we already know and the side we are trying to find, we use the first letters of their names and the phrase "SOHCAHTOA" to decide which function:
</em>
SOH...
Sine: sin(θ) = Opposite / Hypotenuse
...CAH...
Cosine: cos(θ) = Adjacent / Hypotenuse
...TOA
Tangent: tan(θ) = Opposite / Adjacent
1. Sine: sin(θ) = Opposite / Hypotenuse
sin(42°) = y / 22
so on your calculator enter 42 then sin = 0.669
0.669 = y/22 multiply both sides by 22 to get y
y = 14.718
2. is there any other information??
3. The two sides we know are Opposite 40 and Adjacent 48.
SOHCAHTOA tells us we must use Tangent.
Calculate Opposite/Adjacent = 40/48 = 0.833
Find the angle from your calculator using tan-1
Tan y° = opposite/adjacent = 40/48 = 0.833
tan-1 of 0.833 = 39.794°

<u>Answer:</u>
<u>20,000 packages.</u>
<u>Step-by-step explanation:</u>
The rest of the question is as following:
If x represents the number of packages of dog treats, how many packages do they have to sell to break even? Round your answer to the nearest whole number, and do not include units.
=========================================
The function of fixed and variable costs ⇒ C(x) = 1.4x + 2000
The function of revenue ⇒ R(x) = 1.5x
The even situation will happen when costs = revenue
∴ C(x) = R(x)
∴ 1.4 x + 2000 = 1.5x
Solve for x:
∴ 1.5x - 1.4x = 2000
∴ 0.1 x = 2000
∴ x = 2000/0.1 = 20,000
The even will happen when they sell <u>20,000</u> packages
So, To break even, they have to sell more than 20,000 packages .
A: parallel
B: perpendicular
C: neither
D: perpendicular
E: parallel
Explanation: Parallel lines have the same slope. Perpendicular lines have inverted and converted slopes. Neither has neither.
