Sliva [168]2 years ago

Answer: See the screenshot below.

Explanation:

We'll be using these trig functions

  • sine = opposite/hypotenuse
  • cosine = adjacent/hypotenuse
  • tangent = opposite/adjacent

The inverse of those help us find the angle. Notation like arcsine is the same as inverse sine denoted as \sin^{-1} on many calculators.

The decimal results are approximate.

2m+3+4m+5 advice and correct solution
Hunter-Best [27]
Hey there!

On this problem, we have to combine like terms. A like term in this sense doesn't have to have the same coefficient, but it has to have the same variable.

Our like terms are 2m and 4m, along with 3 and 5.

When we add 2m and 4m we get 6m, and when we add 5 and 3 we get eight.
Notice how 5 and three are like terms because they're both whole numbers and don't have any variables.

Your solution is 6m + 8.

My advice to you is pay attention to your like terms and don't mix them up. A strategy is to underline like terms in the same color.

Hope this helps!

The weekly sales of Honolulu Red Oranges is given by
Volgvan

Answer: See Explanation

Step-by-step explanation:

The price elasticity of demand will be calculated as:

q = 860 − 20p.

dq/do = -20

p = 38

Elasticity E(p) = (p/q) × dq/dp

= [38 /(860 - 20p)] × (20)

=38 × 20/(860 - 760)

= 7.6

Therefore, the price elasticity of demand when the price is $38 per orange is 7.6

Revenue = price × quantity

= p × q

= p × (860 − 20p)

= 860p - 20p²

Differentiating with respect to p

= 860 - 40p

40p = 860

p = 860/40

p = 21.50

Maximum Revenue = 860p - 20p²

= 860(21.50) - 20(21.50)²

= 18490 - 9245

= 9245
