Lines a and b are parallel. What is the measuee of angle S?
WITCHER [35]

Answer:

The measure of angle s is 22°

Step-by-step explanation:

Given:

  • Horizontal lines A and B are parallel and are intersecting because a line is going through the both of them.
  • Top right angle of line A is labeled to be 158°, while the top left angle in line B is labeled S° indicating this variable is the missing degrees.

To find:

  • The angle of S, in degrees.

∠1 and 158° are both on a straight line and supplementary.

(Supplementary angles are those angles that sum up to 180 degrees. )

So solving,

⇒ ∠1=180°-158°=22°         ....> Angles ∠1 and S are interior angles

Due to lines A and B being parallel, all interior lines are equal.

As a result, the answer is therefore 22°.

The demand function for a product is p=30−3q where p is the price in dollars when q units are demanded. Find the level of produc
Marina86 [1]

Answer: a) Q= 5units

b) R= $75

Step-by-step explanation:

The maximum revenue is at dR/dq = 0

Revenue = price x quantity of demand = p × q

Substituting p = 30- 3q

R = (30-3q) × q

R= 30q- 3q2 (q2 = q raised to the power of 2)

dR/dq = 30- 6q = 0

6q = 30

q= 30/6= 5

q= 5 units

R = pq= 30q- 3q2

R= 30(5) - 3( 5×5)

R= 150- 75

R= $75

Goodluck...
