Answer:
r = 7
Step-by-step explanation:
The common ratio r of a geometric sequence is
r = 
= 
, that is
r = 
= 
= 7

Answer:
(1)raise, (2)decrease
Step-by-step explanation:
A monopolist's marginal cost curve shifts up, but the firm's demand curve remains the same and the firm does not shut down. Compared with the condition before the increase in marginal costs, the monopolist will <u>raise</u> its price and <u>decrease</u> its level of production.
Marginal cost is the additional cost incurred when one more unit of the output is produced. It is a J-shaped curve, which <em>initially decreases, reaches its minimum and then starts increasing.</em>
Marginal cost is an important factor in economic theory because a company that is looking to maximize its profits will produce up to the point where <em>marginal cost (MC) equals marginal revenue</em>
Answer:
——
y=3x-17
——
Step-by-step explanation:
y=mx+b is the formula
m=slope, b=y-intercept.
Slope is given, 3
So y=3x+b
A point is also given, (3,-8) x=3,y=-8
-8=3(3) + b
-8=9+b
-17=b
So the equation is :
y=3x-17
Hope this helps, let me know if you have any questions!
The equation that best fits the situation is w = 150 * 5 (or the other way around). Since the numbers that would be used are already stated, the equation would be as simple as that. We know that the operation would be multiplication because of the term used "150 for EACH hour" which usually indicates the operation is multiplication.
Hope I helped and good luck!
