The price-demand and cost functions for the production of microwaves are given as
p = 275 − x 60
p = 275 - x 60
and
C(x) = 50000 + 30x
where x is the number of microwaves that can be sold at a price of p dollars per unit and C(x) is the total cost (in dollars) of producing x
Required:
a. Find the profit function in terms of x.
b. Find the marginal cost as a function of x.
c. Find the revenue function in terms of x.
d. Find the marginal revenue function in terms of x.
Answers
Answer:
ALTERNATIVE 1
a. Find the profit function in terms of x.
P(x) = R(x) - C(x)
P(x) = (-60x² + 275x) - (50000 + 30x)
P(x) = -60x² + 245x - 50000
b. Find the marginal cost as a function of x.
C(x) = 50000 + 30x
C'(x) = 0 + 30 = 30
c. Find the revenue function in terms of x.
R(x) = x · p
R(x) = x · (275 - 60x)
R(x) = -60x² + 275x
d. Find the marginal revenue function in terms of x.
R'(x) = (-60 · 2x) + 275
R'(x) = -120x + 275
The answers do not make a lot of sense, specially the profit and marginal revenue functions. I believe that the question was not copied correctly and the price function should be p = 275 - x/60
ALTERNATIVE 2
a. Find the profit function in terms of x.
P(x) = R(x) - C(x)
P(x) = (-x²/60 + 275x) - (50000 + 30x)
P(x) = -x²/60 + 245x - 50000
b. Find the marginal cost as a function of x.
C(x) = 50000 + 30x
C'(x) = 0 + 30 = 30
c. Find the revenue function in terms of x.
R(x) = x · p
R(x) = x · (275 - x/60)
R(x) = -x²/60 + 275x
d. Find the marginal revenue function in terms of x.
R(x) = -x²/60 + 275x
R'(x) = -x/30 + 275
What is the perimeter of triangle ABC?

Answers
The perimeter of the triangle ABC is the sum of the side lengths of the triangle
Using the assumed values, the perimeter of the triangle is 12 units
How to determine the perimeter?Assume the side lengths of the triangle are:
AB = 3
BC = 4
CA = 5
Then the perimeter (P) would be:
P = AB + BC + CA
This gives
P = 3 + 4 + 5 = 12

Find the sum of the first 36 terms of the following series, to the nearest integer.
2, 5,8,...
Answers
The sequence 2,5,8,..... The sum of the 1st 36 terms in arithmetic sequence is 1962.
Given that,
The sequence 2,5,8,.....
We have to find the sum of the 1st 36 terms of the sequence.
We have an sum of the sequence formula from arithmetic sequence.
The sum of all the digits in an arithmetic sequence is determined using the sum of the arithmetic sequence formula. Remember that the addition of the members is the definition of a finite arithmetic sequence. The typical order of the arithmetic sequence is (a, a + d, a + 2d,...), with "a" standing for the first term and "d" for the common difference.
Sum of the arithmetic sequence is S = n/2 {2a + (n − 1) d}
Where
S is the total of the mathematical sequence,
a is the first term,
d is difference of the terms,
n is number of terms in the sequence.
So, now a =2, n=36,d=5-2=3
S=36/2{ 2×2+(36-1)×3}
S=18{4+(35)×3}
S=18(4+105)
S=18×109
S=1962
Therefore, the sum of the 1st 36 terms in arithmetic sequence is 1962.

In a department store the owner paid $15 for 1 kg of sugar. The owner marked the price up by 10% for the customers. How much does he charge for 1kg of sugar?
Answers
15 x 0.10 = 1.50
Then since the owner increased the price by 10%, we simply do 15 + 1.50 which gives us 16.50
Therefore the owner charges $16.50 for 1kg of sugar
Use the following information to find PD and EQ.
AP = 3, PQ = 5, QB = 7, CP=2, and QD = 14
Find PD and EQ
Answers
Answer:
[tex] PD = 18 [/tex]
[tex] EQ = 4 [/tex]
Step-by-step explanation:
Given:
AP = 3,
PQ = 5,
QB = 7,
CP = 2,
QD = 14
Required:
1. PD
2. EQ
SOLUTION:
1. Based on Intersecting Chords Theorem,
[tex] AP*PB = CP*PD [/tex]
AP = 3
PB = PQ + QB = 5 + 7 = 12
CP = 2
PD = ?
Plug in the values into the equation
[tex] 3*12 = 2*PD [/tex]
[tex] 36 = 2*PD [/tex]
Divide both sides by 2
[tex] \frac{36}{2} = PD [/tex]
[tex] 18 = PD [/tex]
[tex] PD = 18 [/tex]
b. Based on Intersecting Chords Theorem,
[tex] EQ*QD = AQ*QB [/tex]
EQ = ?
QD = 14
AQ = AP + PQ = 3 + 5 = 8
QB = 7
Plug in the values into the equation
[tex] EQ*14 = 8*7 [/tex]
[tex] EQ*14 = 56 [/tex]
Divide both sides by 14
[tex] EQ = \frac{56}{14} [/tex]
[tex] EQ = 4 [/tex]

a plumber charges $25 per hour on weekdays and $40 per hour on weekends. The plumber billed a total of 190 hours, worth a total of $5275. Let x represent the number of weekend hours worked, and write algebraic expressions for each of parts a-c below
Answers
Step-by-step explanation:
if x is the amount of weekend hours, let y be the amount of weekday hours. then you can solve for x by using the equations x + y = 190 and 49x + 25y = 5275. once you have values for x and y, the other answers should be easy
Example 3.7.4: The sum of two positive numbers is 16. What is the smallest possible value of the sum of their squares
Answers
Answer:
The smallest possible value of the sum of their squares is 128.
Step-by-step explanation:
Let the first number = x
let the the second number = y
x + y = 16
y = 16 -x
minimum value, f = x² + y²
f(x) = x² + (16-x)²
f(x) = x² + 256 - 32x + x²
f(x) = 2x² - 32x + 256
f(x)' = 4x - 32
4x - 32 = 0
4x = 32
x = 32 / 4
x = 8
The absolute minimum value of x = 8
y = 16 - x
y = 8
The smallest possible value of the sum of their squares is given by x² + y²;
= (8)² + (8)²
= 128
Therefore, the smallest possible value of the sum of their squares is 128.

One study found that the number of interest groups increased by what percentage between 1959 and 1995?
Answers

Percentage change in interest groups between 1959 (500) & 1995 (600) = 20%
Step-by-step explanation:
Percentage change = Change ie (New - Old) x 100
Old value
Suppose -
Number of interest groups in 1959 = 500
Number of interest groups in 1995 = 600
Percentage change = [ (600 - 500) / 500 ] x 100
( 100 / 500 ) x 100 = 20%

Answer: It’s A
Step-by-step explanation: C= -14/3 which is simplified to -4 2/3
Answer:
A.
Step-by-step explanation:
So you foil 2c and -5
Which will give you 5c+4=2c-10
Subtract 2c 5c-2c+4=2c-2c-10
Then You will get3c+4=−10
Step 3: Subtract 4 from both sides.
3c+4−4=−10−4
3c=−14
Step 4: Divide both sides by 3.
3c/3=-14/3
So it will be -14/3 which is -42/3
Which is A.
For these problems,
x
will represent the number of items and
y
will represent the money.
The fixed costs for a certain item are $100 per week. The cost to produce each item is $6 per item.
Using this information, what is the cost equation? Give your answer in slope-intercept form:
Answers
Answer:
y = 6x + 100
Step-by-step explanation:
Slope-intercept form is y = mx + b, where m is the cost to produce each item and b is the fixed cost. Let's input the given values for m and b into the equation:
y = 6x + 100
This is the cost equation. $6 multiplied by x amount of items pluss the fixed cost of $100 gives you the total cost (y) to produce x amount of items.
Hope this helps :)
