Answer:
z = 12
y = 12
x = 12
Step-by-step explanation:
In a 30-60-90 triangle, the longer leg is times the shorter leg and the hypotenuse is 2 times the shorter leg.
In a 45-45-90 triangle, the legs have the same length and the hypotenuse is times a leg
MEMORIZE BOTH OF THE ABOVE.
The altitude to the hypotenuse is the shorter leg of a 30-60-90 triangle. So, it is 1/2 of 24 = 12
Now z = 12
y = 12
x = 12
Answer:
a. The cost function is .
b. The Revenue function is .
c. The profit function is .
d. Selling 500 copies results in a loss of $18.
e. They must sell 680 copies to break even.
Step-by-step explanation:
a. A linear cost function may be expressed as follows:
where is the total cost, b is fixed cost and m is the variable cost.
It costs 41¢ per copy plus fixed costs of $68, so the cost function is
b. Revenue is equal to the number of units sold times the price per unit. To obtain the revenue function, multiply the output level by the price function.
The price you sell the newspapers for is 51¢, and x stands for the quantity that you sell. Thus,
c. The profit a business makes is equal to the revenue it takes in minus what it spends as costs. To obtain the profit function, subtract costs from revenue.
d. Plug 500 into the profit function, which gives
Selling 500 copies results in a loss of $18.
e. To find the break-even point, use the following formula
They must sell 680 copies to break even.
