Answer:
C. 8
Step-by-step explanation:
I almost thought this was going to be Pythagorean Theorem, but no.
Use Cosine Law:
cos θ =
θ = cos−1(0.6)
θ = 53.130...
Now use the SOHCAHTOA ratio for sine () to find x now that you have one angle:
sin θ =
x = 10sinθ (θ isn't needed to be written out as it is shown in the equation above)
x = 8
Answer:
The price is x = $2.779
Step-by-step explanation:
From the question we are told that
The revenue is
The cost of production is
Generally at break even point the cost of production is equal to the revenue
So
=>
Using the quadratic formula to solve this equation we have that
x = $2.779
