A. The elasticity of demand is given by E(x) = x/(V200 - x)²
B. The demand is inelastic at x=$150
C. The price x that maximizes revenue is x=$100.
How to find the elasticity of demand?A. The elasticity of demand is given by:
E(x) = -x(D(x)/dx)/(D(x)/dx)²
D(x) = V200 - x
Therefore, dD(x)/dx = -1
E(x) = -x(-1)/(V200 - x)²
E(x) = x/(V200 - x)²
How to find the demand is elastic or inelastic at x=$150?B. To determine whether the demand is elastic or inelastic at x=$150, we need to evaluate the elasticity of demand at that point:
E(150) = 150/(V200 - 150)²
E(150) = 150/(2500)
E(150) = 0.06
Since E(150) < 1, the demand is inelastic at x=$150.
How to find the price x that maximizes revenue?C. Revenue is given by R(x) = xD(x)
R(x) = x(V200 - x)
R(x) = V200x - x²
To find the price x that maximizes revenue, we need to find the critical point of R(x). That is, we need to find the value of x that makes dR(x)/dx = 0:
dR(x)/dx = V200 - 2x
V200 - 2x = 0
x = V100
Therefore, the price x that maximizes revenue is x=$100.

please please help! i just answered a few questions just to post this im using all my points.
Answer:
Step-by-step explanation:
∠RST=180-44-15
=121°
In ΔRST and ΔLMN,
∠RST=∠LMN (proven)
∠TRS=∠NLM (given)
∴ΔRST ~ ΔLMN (AA)
Answer:
Yes
Step-by-step explanation:
If all the angles in the triangles are the same, then the triangles are similar.
ΔSRT: The angles in a triangle add up to 180. 44+15+x=180, x=121
ΔLMN: The angles in a triangle add up to 180. 44+121+x=180, x=15
Both triangles share the same angles (44,15 and 121), so they are similar.

Stu is buying a &35 tool. The store reduces the price by 5%. How much will Stu pay for the tool?
Correct question is:
stu is buying a $35 tool. The store reduces the price by 5% and then applies an $8 off coupon. How much will Stu pay for the tool
Answer:
$25.25
Step-by-step explanation:
The cost of the tool has been given as $35.
The price of this tool is then reduced by 5%.
When we apply this reduction to initial price
= 35 * 5%
= 35x0.05
= $33.25
If a coupon of 8 dollars is applied
The price to be paid for the tool will be
$33.25 - $8.00
= $25.25
Stu is going to pay $25.25 for the tool
What is the sum of the rational expressions below? 2x + 7 / x + 5 + x - 3 / x + 5
Answer:
[tex]\frac{3x+4}{x+5}[/tex]
Step-by-step explanation:
Given
[tex]\frac{2x+7}{x+5}[/tex] + [tex]\frac{x-3}{x+5}[/tex]
Since both fractions have a common denominator then add the numerators, placed over the common denominator.
= [tex]\frac{2x+7+x-3}{x+5}[/tex]
= [tex]\frac{3x+4}{x+5}[/tex]
Answer:
The answer is
[tex] \frac{3x + 4}{x + 5} [/tex]
Step-by-step explanation:
We can do this by using the denominators.
[tex]then \\ \frac{2x + 7}{x + 5} + \frac{x - 3}{x + 5} \\ = \frac{2x + 7 + x - 3}{x + 5} \\ = \frac{3x + 4}{x + 5} [/tex]

MN = π
Step-by-step explanation:
The arc MN is calculated as
MN = circumference of circle × fraction of circle
= 2πr × [tex]\frac{60}{360}[/tex] ( r is the radius )
= 2π × 3 × [tex]\frac{1}{6}[/tex]
= 6π × [tex]\frac{1}{6}[/tex]

Answer:
There are 77 members in the group.
Step-by-step explanation:
1Rs = 100 paise ( Indian Currency Conversion )
Given,
Total amount collected is = Rs 59.29
Now convert Rs 59.29 to paise that is 59.29 × 100 = 5929 paise
Condition :- Paise collection = Total number of members
Consider any of the above condition as X
So, X² = 5929
X = √5929 = 77
Thus, Total number of members in the group is 77 [ Option C ]

What is the justification for step 2? 4(x-5)= -12 Justification Step 1: 4x-20=-12 Distributive Property Step 2 4x= 8 ? Step 3 x=2 Division Property of Equality
Answer:
addition property of equality
Step-by-step explanation:
Given the equation 4(x-5) = -12
Expand
4x - 20 = -12
Add 20 to both sides (addition property of equality)
4x-20+20 = -12+20
4x = 8
x = 8/4
x = 2
Hence the value of x is 2
The justification for step 2 is addition property of equality

The school production of 'Our Town' was a big success. For opening night, 391 tickets were sold. Students paid $4.00 each, while non-students paid $6.00 each. If a total of $1786 was collected, how many students and how many non-students attended?
Answer:
280 students
111 non students
Step-by-step explanation:
number of students (S)
number of non students (N)
S+N=391 S=391-N
4S+6N=1786
substitute S
4(391-N)+6N=1786
1564-4N+6N=1786
subtract 1564 from each side
2N=222
N=111
S=391-111=280

If 2 feet is equal to 60.96 centimeters how many centimeters are in 12 feet PLEASE HELP
Answer:
365.76
Step-by-step explanation:
If 2 feet is 60.96, then 1 foot is 30.48.
30.48 times 12 = 365.76
365.76 centimeters is the answer.
Hope this helps!
Plz, mark brainliest!
Answer:
365.76 cm in 12 feet
Step-by-step explanation:
Start by setting up two fractions which are equal to one another. We will use x as the unknown amount, which is the number of centimeters in 12 feet here.(see attached picture for a visual)
Now we can cross multiply, which gives us 12*60.96=2*x
Now, solving for x we divide 12*60.96=731.52 by 2, which gives us x=365.76 centimeters in 12 feet.

find the value of z
Answer:
[tex] z = 12 \sqrt{5} [/tex]
Step-by-step explanation:
By geometric mean property:
[tex]y = \sqrt{24 \times 6} \\ \\ y = \sqrt{144} \\ \\ y = 12 [/tex]
By Pythagoras Theorem:
[tex] z = \sqrt{ {12}^{2} + {24}^{2} } \\ \\ z = \sqrt{144 + 576} \\ \\ z = \sqrt{720} \\ \\ z = 12 \sqrt{5} [/tex]
