Johnson's Household Products has a division that produces two sizes of bar soap. The demand equations that relate the prices p and q (in dollars per hundred bars), to the quantities demanded, x and y (in units of a hundred), of the 3.5-oz size bar soap and the 5-oz bath size bar soap are given by p = 80 - 0.01x - 0.005y and q = 50 - 0.005x - 0.015y. The fixed cost attributed to the division is exist10,000/week, and the cost for producing 100 3.5-oz size bars and 100 5-oz bath size bars is exist8 and exist12, respectively.
(a) What is the weekly profit function P(x, y)? P(x, y) =
(b) How many of the 3.5-oz size bars and how many of the 5-oz bath size bars should the division produce per week to maximize its profit? 3.5-oz bars 5-oz bars What is the maximum weekly profit?
Answer:
The weekly profit function P(x,y) = 72x - 0.01x² -0.005xy + 38y - 0.005xy -0.015y² - 10000
3.5 oz bars = 3560
5 oz bars = 80
The maximum weekly profit = 119680
Step-by-step explanation:
Given that:
the demand functions are p and q
the variable cost of x = 8x and the variable cost of y = 12y
Since the fixed cost attributed to the division is exist 10,000/week
∴ the total cost C = 8x + 12y + 10000
R(x,y) = p(x) + q(y)
where ;
xp(x) = 80x -0.01x² -0.005y
yqz(y) = 50 -0.005x -0.015y²
R(x,y) = 80x -0.01x² -0.005xy + 50y -0.005xy -0.015y²
The weekly profit function P(x,y) = R(x,y) - C
P(x,y) = 80x -0.01x² -0.005xy + 50 -0.005xy -0.015y² - ( 8x + 12y + 10000)
P(x,y) = 80x -0.01x² -0.005xy + 50 - 0.005xy -0.015y² - 8x -12y - 10000
P(x,y) = 72x - 0.01x² -0.005xy + 38y - 0.005xy -0.015y² - 10000
(b) How many of the 3.5-oz size bars and how many of the 5-oz bath size bars should the division produce per week to maximize its profit?
profit will be maximized if:
[tex]\dfrac{\partial P}{\partial x} =0 \ and \ \dfrac{\partial P}{\partial y} =0[/tex]
given that:
[tex]\dfrac{\partial^2 P}{\partial x^2} < 0 \ and \ D >0[/tex]
where;
D = Px Py -Pxy²
Now;
[tex]\dfrac{\partial P}{\partial x} =(-0.02 x -0.01 y +72)[/tex]
[tex]\dfrac{\partial P}{\partial y} =(-0.03 x -0.01 y +38)[/tex]
[tex]\dfrac{\partial P}{\partial x} =0 \to 2x+y = 7200[/tex]
[tex]\dfrac{\partial P}{\partial y} =0 \to x+3y = 3800[/tex]
2x + y = 7200
2x + 6y = 7600
5y = 400
y = 400/5
y = 80
From
x + 3y = 3800
x + 3(80) = 3800
x = 3800 - 240
x = 3560
∴ 3.5 oz bars = 3560
5 oz bars = 80
What is the maximum weekly profit?
The maximum weekly profit = 72x - 0.01x² -0.005xy + 38y - 0.005xy -0.015y² - 10000
The maximum weekly profit = 72(3560) - 0.01(3560)² -0.005(3560)(80) + 38(80) - 0.005(3560)(80) -0.015(80)² - 10000
The maximum weekly profit = 256320 - 126736 - 1424 + 3040 - 1424 -96 - 10000
The maximum weekly profit = 119680
Need help Bad sow work need that to 1. Megan works at Amazon’s warehouse. She is responsible for packing boxes into crates for shipment. Each crate can hold 32 boxes, and she needs to ship 712 boxes. a. Megan thinks she can fit all 712 boxes into 22 crates. Is her estimate correct? Why or why not? EXPLAIN YOUR REASONING b. How many crates will Megan need to pack all 712 boxes? Round to the nearest whole number. SHOW YOUR WORK
Answer:
a) her estimate is wrong, because 22 crates can only contain 704 boxes
b) 23 crates
Step-by-step explanation:
Each crate can hold 32 boxes and there are total of 712 boxes.
Megan thinks she can fit all 712 boxes into 22 crates.
Now multiplying 22 crates 32 boxes to know the number of boxes22 crates can contain
= 22*32
= 704 boxes
The boxes are not all contacts in 22 crates
To pack 712 boxes
She Will need = 712/32 crates
She will need= 22.25 crates
Rounding up to whole number she will need 23 crates

Use the numerals 1,7,7,7, and 7 to create the number 100
Answer:
[tex]77\div.77\cdot1[/tex]
Step-by-step explanation:
What we're basically looking for here are ways to get 100 using these numbers.
My immediate first thought was "can we divide the 7's by some 7's to get 100?"
I know that [tex]7 \div .7=10[/tex], so I had the idea to make it [tex]77 \div .77 = 100[/tex]. This means that we can use the number 7 four times in the equation [tex]77 \div .77=100[/tex].
However, we're still missing a 1 that we need to include. This is easy, we can just multiply [tex]77 \div .77[/tex] by 1.
So in conclusion, we get [tex]77 \div .77\cdot1[/tex]
Hope this helped!

Answer:
The cosine of angle C is 5/13, or approximately 0.38.
Step-by-step explanation:
To solve this problem, we must remember what the cosine of an angle represents. The cosine of an angle is equal to the ratio of the adjacent side divided by the hypotenuse.
From the diagram, we can determine that the adjacent side length is 10 and the hypotenuse is 26.
Therefore, the cosine of angle C is:
10/26 = 5/13 (simplified)

Find the axis of symmetry and vertex for the parabola y=-4x^2-32x-10
Answer:
Axis of Symmetry: x = -4
Vertex: (-4, 54)
Step-by-step explanation:
We use a graphing calc.
Answer:
the equation of the axis of symmetry is [tex]x=-4[/tex]
Step-by-step explanation:
Recall that the x-value of the vertex of a parabola of the form:
[tex]y=ax^2+bx +c[/tex]
is given by the expression:
[tex]x_{vertex}=-\frac{b}{2\,a}[/tex]
therefore, in our case the x-position of the vertex becomes;[tex]x_{vertex}=-\frac{b}{2\,a}=\frac{32}{-8} =-4[/tex]
and since the equation of the axis of symmetry is [tex]x=x_{vertex}[/tex]
Then, the equation of the axis of symmetry is [tex]x=-4[/tex]
Y=2x+2 graph the equation using the slope and y-intercept
Answer:
See graph attached
Step-by-step explanation:
Our life is simple because the equation [tex]y=2x+2[/tex] is already put in slope-intercept form.
This form is called slope-intercept because it states exactly what it's called: The number multiplied by [tex]x[/tex] (the constant of proportionality, in this case, 2) is the slope - and the y-intercept is what is being added to the equation (in this case, also 2, since there is a +2 at the end.)
With this info, we can start graphing.
We know that the y-intercept is 2, meaning one point will be (0,2).
We also know that the slope is 2, meaning every time x increases by 1, y will increase by 2. So the next point is (1, 4), the next is (2, 6), and so on.
Hope this helped!

Find an equation of the line passing through the point (−6,−5) that is parallel to the line y=4/3x−5
Answer:
The answer is
[tex]y = \frac{4}{3} x + 3[/tex]Step-by-step explanation:
Equation of a line is y = mx + c
where
m is the slope
c is the y intercept
To find the equation of the parallel line we must first find the slope of the original line
y = 4/3x - 5
Comparing with the general equation above
Slope/ m = 4/3
Since the lines are parallel their slope are also the same
So we have
Slope of parallel line = 4/3
Equation of the line using point (−6,−5) and slope 4/3 is
[tex]y + 5 = \frac{4}{3} (x + 6) \\ y + 5 = \frac{4}{3} x + 8 \\ y = \frac{4}{3} x + 8 - 5[/tex]We have the final answer as
[tex]y = \frac{4}{3} x + 3[/tex]Hope this helps you.

Two canoes travel down a river, starting at 10:00. One canoe travels twice as fast as the other. After 3.5 hr, the canoes are 5.25 mi apart. Find the average
rate of each canoe.
Answer:
Step-by-step explanation:
The time for each canoe is 3.5 hours
The total distance traveled by the first canoe is not known. Nor is the distance for the second canoe. We do know that the difference is 5.25 miles.
So let the rate of the slower canoe = x
Let the rate for the second canoe = 2x
The first canoe goes a distance of 2*x * 3.5 = 7x
The second canoe goes a distance of 3.5x
The difference = 7x - 3.5x = 5.25
3.5x = 5.25 divide by 3.5
x = 5.25/3.5
x = 1.5 which is the rate of the slower canoe
2x = 3 which is the rate of the faster canoe

If mountains rose by 1 mm/yr, how high would they be (in meters) after 1,000 years? 10 million years? 50 million years?
Answer:
a)after 1,000 years?
1 meter
b) 10 million years?
10,000 meters
c) 50 million years?
50,000 meters
Step-by-step explanation:
We are told in the question that mountains rise 1 mm per year.
a) After 1000 years
1 year = 1 mm
1000 years =
Cross Multiply
1000 × 1 mm
= 1000mm
Converting to meters
1 mm = 0.001 m
1000 mm =
1000 × 0.001m
= 1 meter
b) After 10 million (10,000,000) years
1 year = 1 mm
10000000years =
Cross Multiply
10000000 × 1 mm
= 10,000,000mm
Converting to meters
1 mm = 0.001 m
10,000,000mm =
10,000,000 × 0.001m
= 10,000 meters
c) After 50 million years(50,000,000)
After 50,000,000 years
1 year = 1 mm
50,000,000years =
Cross Multiply
50,000,000 × 1 mm
= 50,000,000mm
Converting to meters
1 mm = 0.001 m
50,000,000mm =
50,000,000 × 0.001m
= 50,000 meters

Annie is running a trail that is 4 1/2 miles long. She ran the first 2/3 of the distance. Then the trail became very steep, so she slowed down to a walk. Annie walked for 1/2 of the remaining distance and then ran again for the rest of the way. How far did Annie walk? Write the answer as a simplified fraction.
Answer:
[tex]\frac{3}{4}[/tex] miles
Step-by-step explanation:
Total length of the trail = [tex]4\frac{1}{2}[/tex] miles = [tex]\frac{9}{2}[/tex] miles
She ran the first [tex]\frac{2}{3}[/tex] of the distance i.e.
The distance for which she ran = [tex]\frac{2}{3} \times \frac{9}{2} = 3\ miles[/tex]
Remaining distance = Total length of trail minus the distance for which she has already run = [tex]\frac{9}{2} - 3 = \frac{3}{2}[/tex] miles
Given that: After running, Annie has to walk due to steep nature of the trail, So, Annie walked for [tex]\frac{1}{2}[/tex] of the remaining distance.
The distance for which Annie walked = [tex]\frac{1}{2} \times[/tex] Remaining distance
The distance for which Annie walked = [tex]\frac{1}{2} \times[/tex] [tex]\frac{3}{2}[/tex] = [tex]\frac{3}{4}[/tex] miles
So, the answer is: [tex]\frac{3}{4}[/tex] miles
