Given:
Marginal revenue (in dollars per unit) for a month is
[tex]MR=-0.5x+400[/tex]
To find:
The total revenue from the production and sale of 30 units.
Solution:
We know that, total revenue is integration of marginal revenue with respect to quantity.
[tex]TR=\int MR dx[/tex]
[tex]TR=\int (-0.5x+400) dx[/tex]
[tex]TR=-0.5\int x dx+400\int 1 dx[/tex]
[tex]TR=-0.5\times \dfrac{x^2}{2}+400x[/tex]
Now, substitute x=30 in the equation of Total Revenue (TR).
[tex]TR=-0.5\times \dfrac{30^2}{2}+400(30)[/tex]
[tex]TR=-0.5\times \dfrac{900}{2}+12000[/tex]
[tex]TR=-225+12000[/tex]
[tex]TR=11775[/tex]
Therefore, the total revenue from the production and sale of 30 units is $11,775.

Margie bought 1 1/2
pounds of tomatoes for $2.00 per pound,
1/4 pound of onions for $1.60 per pound, and 1 pound of apples for $1.65 per pound. How much did she pay for her total purchase?
Answer:
She spent $5.05 for her total purchase.
Step-by-step explanation:
First, you should convert the fractions into decimals to make it easier, which would make it, 1.5, .25, 1.
Second, multiply 1.5 by 2 because there are 1.5 pounds which are payed for $2.00. Do the others fractions corresponding with the number of pounds and the cost this same way. 1.5 multiplied by 2 is 3. .25 multiplied by 1.60 is 0.4, 1 multiplied by 1.65 is 1.65.
Lastly, Add it all up, 3+0.4+1.65=5.05

what is 5/6 rounded to the nearest hundredth?
Answer:
0.83
First, we convert the fraction to a decimal number by dividing the numerator by the denominator:
5 / 6 = 0.833
There are two parts to the decimal number above:
Integer Part: 0
Fractional Part: 833
Now, we will make the Fractional Part just two digits (nearest hundredth) by using our rounding rules.*
In this case, Rule I applies, so 5/6 (or 0.833) rounded to the nearest hundredth in decimal format is:
0.83

Simply find the value inbetween the x values and y values. You can do this by adding the x values and then dividing them by 2 to find the x value for a midpoint, then do the same for the y value.
Write an equation in slope-intercept form of the line shown.
Answer:
Step-by-step explanation:
y2-y1/x2-x1
1+3
3-1
your slope is 4/2 or 2. keep going down to find what y is when x is 0, which happens to be -5
so now you have a slope and a y intercept you can solve like y=mx+b where m is your slope and B is your y intercept
y=2x-5 is your answer

Name an object that could be about the same length as each measurement. A. 4 inches b. 6 feet c. 1 meter d. 5 yards a. 6 centimeters b. 2 millimeters c. 3 kilometers
Answer and Step-by-step explanation:
A. 4 inches: An object that's 4 inches is about 2.54 centimeters or 25.4 millimeters. An business envelope is typically about 4 inches by 9 inches for example.
B. 6 feet: A 6 feet object is quite big when compared to just 4 inches. A feet is 12 inches hence 6 feet is 72 inches. A very tall human being is typically 6 feet.
C. 1 meter: A meter is about 39.37 inches hence it is quite big when compared to a feet. A baseball bat is one meter long.
D. 5 yards: A yard is 36 inches hence a bit smaller than a meter. A trampoline could be 5 yards for example
E. 6 centimeters: one centimeter is 0.394 inches hence smaller than an inch. A 6 centimeters object for example is pencil for writing.
F. 2 millimeters: a millimeter is 0.0394 inches hence smaller than a centimeter and an inch. An orange seed could be 2 millimeters long

Write an expression that is equivalent to 1/2a - 4
The expression that is equivalent to 1/2a - 4 is 1/2 (a - 16)
Given the expression 1/2a - 8, to get the equivalent expression, we will factor out 1/2 from the expression to have:
1/2 (a - 8 (2))Note that we will need to multiply the second term by the denominator of the fraction to neutralize the fraction.
Simplify to have:
1/2 (x - 8 (2))1/2 (x - 16)Hence the expression that is equivalent to 1/2a - 4 is 1/2 (a - 16)

Is X 10?
Step-by-step explanation:
One vertex of a polygon is located at (3, –2). After a rotation, the vertex is located at (2, 3).
Which transformations could have taken place? Select all options.
Group of answer choices
90°
180°
270°
-270°
-180°
–90°
Answer:
Step-by-step explanation:
The vertex has a rotation (3,-2) --> (2,3).
or in x and y coordinates, (x,y) --> (-y,x).
the rotation that has this said rule is r0, 90°. and 90° is equal to –270°.
the answers are:
r0, 90°
r0, –270°.
The transformations could have taken place are 270°or -90°.
What is Transformation?
A point, line, or geometric figure can be transformed in one of four ways, each of which affects the shape and/or location of the object. Pre-Image refers to the object's initial shape, and Image, after transformation, refers to the object's ultimate shape and location.
We have,
Before rotation V(3, -2)
and, After rotation V'(2, 3)
Then, the possible transformations from V to V' are:
90 degrees counterclockwise rotation
270 degrees clockwise rotation
If the there is 90 degrees counterclockwise rotation (R0, -90) is given as:
(x, y) - > (-y, x)
Then we have (3, -2) -> (2, 3)
and, if 270 degrees clockwise rotation
(x, y) - > (-y, x)
Then we have (3, -2) -> (2, 3)
Thus, the transformation are 270°or -90°.

Only one color, but not one size,
Stuck at the bottom, yet easily flies.
Present in sun, but not in rain,
Doing no harm, and feeling no pain.
What is it?
Answer:
The first riddle is Age. Some people love their age, some people hate their age. Age can change appearances and thoughts because as you mature you view things differently. If you take care of yourself, you will become die older than most people. Some people are fooled by age, they think someone is older or younger than they really are. Some people don't know someone's age, so it is a mystery. Some people try and hide their age. Age never decreases.
The second riddle is a shadow. A shadow is only one color, but it can be any shape or size. Shadows are stuck at the bottom, but it easily moves. Shadows appear in the sun, but not when it is raining because of the clouds. Shadows do no harm, and they can't feel anything.

Suppose that
g(x) = f(x)•h(x),
f(3) = 6,
h(3) = 2,
h'(6)=4,
h'(3)=15 and
f'(3) = 8.
Find g(3).
(A) 32
(C) 106
(B) 8
(D) 60
Answer:
g(3) = 6*2 = 12
Step-by-step explanation:
In this problem you're given more information than is necessary to solve it.
g(x) = f(x)*h(x) is the product of functions f and h.
If x has the value 3, then:
f(x) = f(3) = 6, h(x) = h(3) = 2. Thus, when x = 3 we have g(x) = g(3) = 6*2 = 12
The value of g(3) using g(x) = f(x)·h(x) is 12.
Given that, g(x) = f(x)·h(x).
What is the function?Functions are the fundamental part of the calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.
Put x=3 in g(x) = f(x)·h(x), we get
g(3) = f(3)·h(3)
⇒ g(3) =6×2
= 12
Therefore, the value of g(3) using g(x) = f(x)·h(x) is 12.

8+10+8.9+10+4=40.9
hope this helps :3
if it did pls mark brainliest
Answer:
40.9 ft
Step-by-step explanation:
Perimeter is the sum of lengths of all outer sides of the shape. Since the rectangle has two pairs of parallel lines of the same length... It is safe to assume that the unmarked side length is 10 ft (just like it's parallel counterpart)
Now it is a simple matter of adding all of the outer sides.
8ft + 10 ft + 10 ft + 8.9 ft + 4 ft = 40.9 ft
Pablo mixes 3 units white paint and 1 unit black paint to make gray paint. What two equations show the relationship between units of white paint, w, and units of black paint, b? Show your work.
Answer:
[tex]w = \frac{1}{3}b[/tex] and [tex]b = 3w[/tex]
Step-by-step explanation:
Represent white paint with w and black with b
Given
When w = 3; b = 1
Required
Determine the two equations
To get a gray paint, the w and b are needed in the following proportion:
[tex]3 * w = 1 * b[/tex] -----(1)
Solve for b
[tex]3 * w = b[/tex]
Reorder
[tex]b = 3 * w[/tex]
[tex]b = 3w[/tex] ---- This is an equation
To get another equation,
Recall that
[tex]3 * w = 1 * b[/tex]
Solve for w
[tex]3*w = b[/tex]
[tex]3w = b[/tex]
Make w the subject
[tex]w = \frac{1}{3}b[/tex]
Hence, the equations that show the relationship between w and b are:
[tex]w = \frac{1}{3}b[/tex] and [tex]b = 3w[/tex]
