Answer:
(a)
(b)
(c)R'(5400)=$394
Step-by-step explanation:
Given that x is the quantity demanded and the speaker's unit price (in dollars) is p where:
p = −0.02x + 610 (0 ≤ x ≤ 20,000)
(a)Revenue function R.
Revenue = Price X Quantity Demanded
Therefore:
R(x)=xp
(b)Marginal revenue function R'(x)
If
Then, the marginal revenue function
(c)We want to compute R'(5,400)
From the above, we can infer that the revenue that will be generated on the sales of the 5401st item is $394.
Since I do not have answer choices, I can conclude things that may or may not be an answer choice. Just from the problem, you can tell that Marie lost more weight, because 175 -150 = 25, while 190 - 180 = 10. Indirectly, you can say that she might have worked out more, or changed her diet, although that would merely be an inference. If you have answer choices please let me know and I can answer more. Hope this helps. Please rate, leave a thanks, and mark a brainliest answer (Not necessarily mine).
Answer:
k = 9/4
Step-by-step explanation:
To find k, use the equation
y = kx
Pick a point
72 = k *32
Divide each side by 32
72/32 = k
9/4 = k
14^2 is the same as saying 14x14
=196
Answer:
x = 12
Step-by-step explanation:
The segment from the vertex to the base is a perpendicular bisector.
Using Pythagoras' identity on the right triangle on the right.
(
x )² + 3² = (
)² , that is
x² + 9 = 45 ( subtract 9 from both sides )
x² = 36 ( multiply both sides by 4 )
x² = 144 ( take the square root of both sides )
x = 
= 12
