Answer:
[tex](\frac{6x^2y}{5})[/tex]
Step-by-step explanation:
Given
[tex]\frac{(2x)(3x^3y^2)}{5x^2y}[/tex]
Required
Solve
Open the brackets
[tex]\frac{(2x)(3x^3y^2)}{5x^2y}[/tex] = [tex]\frac{(2x*3x^3y^2)}{5x^2y}[/tex]
[tex]\frac{(2x)(3x^3y^2)}{5x^2y}[/tex] = [tex]\frac{(6x^4y^2)}{5x^2y}[/tex]
Apply law of indices:
[tex]\frac{(2x)(3x^3y^2)}{5x^2y}[/tex] = [tex]\frac{(6x^{4-2}y^{2-1})}{5}[/tex]
[tex]\frac{(2x)(3x^3y^2)}{5x^2y}[/tex] = [tex]\frac{(6x^2y)}{5}[/tex]
[tex]\frac{(2x)(3x^3y^2)}{5x^2y}[/tex] = [tex](\frac{6x^2y}{5})[/tex]
Let C(x) represent the cost of producing x items and p(x) be the sale price per item if x items are sold. The profit P(x) of selling x items is P(x)=x p(x)-C(x) (revenue minus costs). The average profit per item when x items are sold is P(x)/x and the marginal profit is dP/dx. The marginal profit approximates the profit obtained by selling one more item given that x items have already been sold. Consider the following cost functions C and price functions p. Complete partsâ (a) throughâ (d) below.
a. Find the profit function P.
b. Find the average profit function and marginal profit function.
c. Find the average profit and marginal profit if x=a units are sold.
d. Interpret the meaning of the values obtained in part (c).
C(x)=â0.02x^2 +50x+100, p(x)=100, a=500
Answer:
[tex](a)[/tex] [tex]P(x) = 0.02x^2 +50x - 100[/tex]
[tex](b)[/tex] [tex]Average = 0.02x + 50 - \frac{100}{x}[/tex] and [tex]Marginal = 0.04x + 50[/tex]
[tex](c)[/tex] [tex]Average = 59.8[/tex] and [tex]Marginal = 70[/tex]
(d) See Explanation
Step-by-step explanation:
Given
[tex]p(x) = 100[/tex]
[tex]C(x) = -0.02x^2 +50x +100[/tex]
Solving (a) Profit function; P(x)
[tex]P(x) = xp(x) - C(x)[/tex]
This gives:
[tex]P(x) = x*100 - (-0.02x^2 + 50x + 100)[/tex]
[tex]P(x) = 100x + 0.02x^2 - 50x - 100[/tex]
Collect like terms
[tex]P(x) = 0.02x^2 - 50x +100x - 100[/tex]
[tex]P(x) = 0.02x^2 +50x - 100[/tex]
Solving (b): Average profit function and Marginal profit function
[tex]Average = \frac{P(x)}{x}[/tex]
This gives:
[tex]Average = \frac{0.02x^2 + 50x - 100}{x}[/tex]
Break down the fraction
[tex]Average = \frac{0.02x^2}{x} + \frac{50x}{x} - \frac{100}{x}[/tex]
[tex]Average = 0.02x + 50 - \frac{100}{x}[/tex]
[tex]Marginal = \frac{dP}{dx}[/tex]
[tex]P(x) = 0.02x^2 +50x - 100[/tex]
Differentiate
[tex]\frac{dP}{dx} = 2 * 0.02x + 50 - 0[/tex]
[tex]\frac{dP}{dx} = 0.04x + 50[/tex]
Hence:
[tex]Marginal = 0.04x + 50[/tex]
Solving (c): Average profit and Marginal profit if x = a
[tex]a = 500[/tex]
So:
[tex]x =500[/tex]
Substitute 500 for x
[tex]Average = 0.02x + 50 - \frac{100}{x}[/tex]
[tex]Average = 0.02 * 500 + 50 - \frac{100}{500}[/tex]
[tex]Average = 59.8[/tex]
[tex]Marginal = 0.04x + 50[/tex]
[tex]Marginal = 0.04*500 + 50[/tex]
[tex]Marginal = 70[/tex]
Solving (d): Interpret the values in (c)
[tex]Average = 59.8[/tex]
They make a profit of 59.8 for the first 500 items
[tex]Marginal = 70[/tex]
From the 501st item, the profit is 70

Answer:
Sin A = 22/33.3 ≈ 0.7
Step-by-step explanation:
Sin A = opp/hyp
Opp = 22
Adj = 25
Apply pythagorean theorem to find the hypotenuse length.
Thus:
Hyp = √(25² + 22²) ≈ 33.3
Therefore,
Sin A = 22/33.3 ≈ 0.7 (nearest tenth)

Answer:
Step-by-step explanation:
7C10 = 10!/(7!)(10-7)!
7C10 = 10!/(7!)(3!)
7C10 = (10 x 9 x 8 x 7)/(7 x 6 x 5)(6)

Mary always saved 45% of his salary. When his salary decreased by 20% in April, his savings decreased by $180.
How much was Mary’s salary before the decease?
Answer:
Step-by-step explanation:
Answer:
Is Mary a guy? :|
Step-by-step explanation:
I did this by just a good guess , not really the right way
2000*.45=900 ( 900 is the old savings)
2000*.2 =400 ( how much her salary went down by )
2000-400=1600 ( new salary )
1600*.45 = 720 ( 45% of new salary is new savings
900-720=180 ( change in savings is 180 , the amount the question asks for)
Mary's old salary was 2,000

a room is 12 CM long and 8 m broad. find the ratio of i) length to breadth II) breadth to length
Answer:
i. Length : breadth = 3 : 200
ii. Breadth : length = 200 : 3
Step-by-step explanation:
Given the following data;
Length = 12cm
Breadth = 8m to centimeters = 8 * 100 = 800 centimeters.
To find the following;
a. Length to breadth ratio.
Length : breadth = 12 : 800
We would divide both sides by 4
Length : breadth = 3 : 200
b. Breadth to length.
Breadth : length = 800 : 12
We would divide both sides by 4
Breadth : length = 200 : 3
Note: In order to find a ratio, we must ensure that the units of the given parameters (quantities) are the same.

39.25 miles is 46.5% of how many miles?
Answer:
84.41 miles
Step-by-step explanation:
For this one, all you have to do is set up a proportion. You can do that by setting it as (39.25/x)=(46.5/100). You cross multiply to get 39.25(100)=46.5(x). From there, you simplify to get 3,925=46.5x. Divide both sides by 46.5 to get x alone, and you should get your answer, 84.41.
Let the measure of Arc B C D = a°. Because Arc B C D and Arc B A D form a circle, and a circle measures 360°, the measure of Arc B A D is 360 – a°. Because of the ________ theorem, m∠A = StartFraction a Over 2 EndFraction degrees and m∠C = StartFraction 360 minus a Over 2 EndFraction degrees. The sum of the measures of angles A and C is (StartFraction a Over 2 EndFraction) + StartFraction 360 minus a Over 2 EndFraction degrees, which is equal to StartFraction 360 degrees Over 2 EndFraction, or 180°. Therefore, angles A and C are supplementary because their measures add up to 180°. Angles B and D are supplementary because the sum of the measures of the angles in a quadrilateral is 360°. m∠A + m∠C + m∠B + m∠D = 360°, and using substitution, 180° + m∠B + m∠D = 360°, so m∠B + m∠D = 180°.
What is the missing information in the paragraph proof?
Answer:
A. Inscribed Angle
Step-by-step explanation:
Because the angles are inscribed in the circle, the angle lie on arcs which mean that the angles have to add up to 360 degrees just like a circle is 360 degrees, making it a quadrilateral that is inscribed!
The missing information in the paragraph proof should be considered as the Inscribed Angle.
What is Inscribed Angle?In terms of geometry, an inscribed angle should be the angle that should be created in the interior of a circle at the time when two chords intersect on the circle. Since the angles should be inscribed in the circle so here the angles should be added up to the 360 degrees same as like the circle also at the same time it should make the quadrilateral
Therefore, The missing information in the paragraph proof should be considered as the Inscribed Angle.

How
Many small circles of radius 7cm
can be got from big
big circle of radius
35cm
Answer:
Let get x as a number of small circles.
Area of big circle = Area of all small circles
(Here . implies multiplication)
22/7 . 35 cm .35cm = 22/7 . 7cm .7cm .x
x = (22/7 . 35 cm .35cm) / (22/7 . 7 cm .7cm)
x = (35 . 35) /(7.7)

Write an equation in slope-intercept form that represents the data.
Answer:
1) y = 5x + 100
2) y = -10x + 375
Step-by-step explanation:
The slope intercept form of an equation is expressed as y = mx+c
m is the slope
c is the intercept
1) Using the coordinate points (0,100) and (1, 105)
slope m = 105-100/1-0
m = 5/1
m = 5
Substitute m = 5 and (0,100) into the formula y = mx+c
100 = 5(0)+c
100 = 0 + c
c = 100
The required equation is y = 5x + 100
2) Using the coordinate points (0,375) and (5 325)
slope m = 325-375/5-0
m = -50/5
m = -10
Substitute m = -10 and (0,375) into the formula y = mx+c
375 = -10(0)+c
375 = 0 + c
c = 375
The required equation is y = -10x + 375
