The daily production cost, C, for x units is

disa [49]

I think the correct equation is

c(x) = 200 - 7x + 0.345x^2.

Domain is the set of x-values (i.e. units produced) that are feasible. This is all the positive integer values + 0, in case that you only consider that can produce whole units.

Range is the set of possible results for c(x), i.e. possible costs.

You can derive this from the fact that c(x) is a parabole and you can draw it, for which you can find the vertex of the parabola, the roots, the y-intercept, the shape (it open upwards given that the cofficient of x^2 is positive). Also limit the costs to be positive.

You can substitute some values for x to help you, for example:

x y

0 200

1 200 -7 +0.345 = 193.345

2 200 - 14 + .345 (4) = 187.38

3 200 - 21 + .345(9) = 182.105

4 200 - 28 + .345(16) = 177.52

5 200 - 35 + 0.345(25) = 173.625

6 200 - 42 + 0.345(36) = 170.42

10 200 - 70 + 0.345(100) =164.5

11 200 - 77 + 0.345(121) = 164.745

The functions does not have real roots, then the costs never decrease to 0.

The function starts at c(x) = 200, decreases until the vertex, (x =10, c=164.5) and starts to increase.

Then the range goes to 164.5 to infinity, limited to the solutcion for x = positive integers.

Does anyone know how to do this ?

goldenfox [79]

Answer: D) 32

Step-by-step explanation:

The area of a parallelogram equals its base times its height. Substitute the base and area into this formula to solve for the height:

A=bh

40=(5)(h)

h=8

If ABCD is a parallelogram, opposite sides are parallel, so AB is parallel to DC. If AB is parallel to DC, EB is parallel to DC. Since EB is parallel to DC, quadrilateral EBCD has at least one pair of parallel sides, making it a trapezoid. The area of a trapezoid is equal to $\frac{h(b_{1}+b_{2}) }{2}$ where h is the height, $b_{1}$ is one base, and $b_{2}$ is the other base. Plug the necessary values into the formula:

A= $\frac{h(b_{1}+b_{2}) }{2}$

$b_{1} =AB-AE\\DC=AB\\b_{1} =DC-AE\\b_{1} =5-2\\b_{1} =3$

$b_{2} =5$

h=8

A= $\frac{8(3+5)}{2}$

A=32

The answer is D) 32.

A 64 foot rectangular segment of a support beam for a bridge is divided into 3 parts whose lengths have the ratio of 3:5:8 what

Lyrx [107]

Answer:

32 feet

Step-by-step explanation:

The total of ratio units is 3+5+8 = 16. Of those, the longest part is 8/16 = 1/2 of the total length. That is (1/2)·64 ft = 32 ft.

The longest part is 32 feet.

Solve for t in scientific formula d=rt

yarga [219]

The problem is: d=rt
you are solving for r

d=rt
-- --
t t

you divide both sides by r, so your answer is:

d/t=r or r=d/t

I hope this helped! :))
