Answer:
Infinity (∞)
Step-by-step explanation:
Graph the function and observe that the function P(t) increases without bound as x increases.
he needs at least 5800
5800/725
8
so he must sell at least 8 cars
There are only 45 cars on the lot, so that is the max he can sell
Choice C
8<=x<=45
From any proportion, we get another proportion by inverting the extremes (or the means):
= k
so we have:
2x=3k
2x+y=2k therefore:
3k+y=2k
y= - k
x=
= -
The corect answer is A. -3/2
or:
From any proportion, we get another proportion by inverting the extremes and the means:
We use a property of proportions:
where a, d are extremes and b,c are means and the product of the extremes equals the product of the means (a*d=b*c),
so we have
or
(you can check this also by "the product of the extremes equals the product of the means")
3y = - 2x
a. The total cost is the sum of variable and fixed cost.
So the average cost of each hat is simply total cost divided by x:
ave cost = (2.12 x + 3000) / x
b. Total cost should be equal to Income:
2.12 x + 3000 = 2.75 x
Solve for x:
x = 4762 units
c. Profit is income minus total cost:
Profit = 2.75 x – (2.12 x + 3000)
1000 = 2.75x – 2.12 x – 3000
Solving for x:
<span>x = 6439 hats</span>
Step-by-step explanation:
x^2 + y^2 = r^2 --> r =
=
cos = x /r = -4 /
sin = y /r = 5/
tan = sin /cos = -5 /4
