A company’s profit, P, in dollars, for producingx machines in one day is given by P = 500x - 20x*2.If the company produces 10 ma
Slav-nsk [51]

The profit of that day is (C) P = $3,000.

<h3>What is profit?</h3>
  • A profit is a difference between the revenue generated by an economic entity's outputs and the opportunity costs of its inputs.
  • Total revenue minus total cost, including both explicit and implicit costs, equals total revenue.
  • Unlike accounting profit, it only refers to the explicit costs that appear on a company's financial statements.
  • Accounting profit is calculated by subtracting the firm's total revenue from only the firm's explicit costs.
  • When analyzing a firm, an economist considers all opportunity costs, both explicit and implicit.

To find the profit of that day:


Given:

  • P = 500x − 20x², where 'x' is the number of machines per day produced.
  • If the company produces 10 machines in one day, that is x = 10.

By substituting x = 10 in the above equation, we get:

  • P = 500 × 10 - 20 × 10²
  • P = 5000 - 2000
  • P = 3,000/

Therefore, the profit of that day is (C) P = $3,000.

A carpenter cut a board 3 3/4 feet long to make a shelf. Before he cut the board, it was 10 1/2 feet long.
viva [34]
Subtract 3 3/4 from 10 1/2.  Note that the LCD is 4, so 10 1/2 = 10 2/4.

What is    10 2/4
               -  3 3/4
-------------------------
                     ?

Since 2/4 is smaller than 3/4, you must borrow 1 from that 10.

Now your problem looks like   9 6/4
                                               -3 3/4
                                             ----------
                                                 6 3/4   (answer)

The remnant of the board is 6 3/4 feet long.

Write and solve an equation to find the value of x and the missing angle measures
MatroZZZ [7]

Answer:

in explanation

Step-by-step explanation:

angle rules say that those angles respond to each other meaning

they will equal each other

so 6x-4=4x+14

now solve for x

x=9

the top angle will be

6(9)-4=50

bottom angle will be 50

4(9)+14=50

Find the coordinates of the point on a circle with radius 4 at an angle of 2pi/3
dmitriy555 [2]

Answer:

The coordinates of the point on a circle with radius 4 at an angle of \frac{2\pi}{3} radians are x = -2 and y = 3.464.

Step-by-step explanation:

This problem ask us to determine the rectangular coordinates from polar coordinates. The polar coordinates of the point in rectangular form is expressed by the following expression:

(x,y) = (r\cdot \cos \theta, r\cdot \sin \theta)

Where r and \theta are the radius of the circle and the angle of inclination of the point with respect to horizontal, measured in radians. If r = 4 and \theta = \frac{2\pi}{3}\,rad, the coordinates of the point are:

(x,y) = \left(4\cdot \cos \frac{2\pi}{3},4\cdot \sin \frac{2\pi}{3}  \right)

(x,y) = (-2, 3.464)

The coordinates of the point on a circle with radius 4 at an angle of \frac{2\pi}{3} radians are x = -2 and y = 3.464.

Find the missing angle please!!
beks73 [17]
Step 1: All angles in a triangle must add up to 180! Therefore, in the upper triangle, add up the two you know 85+35=120 so the missing angle is 60.
Step 2: Bottom triangle. Your new angle above (60) is the pair of the opposite angle - so it too is 60. So now you know 2 of the 3 angles: 60+64=124 Subtract that from 180 and you get 56...which is the answer for ?
