Answer:

£104

Step-by-step explanation:

5:3 = 65:X

65÷5=13

X=13×3

x=39

total=65+39

total=104

C = 200 – 7x + 0.345x2

fenix001 [56]

The way to find the domain and the range is illustrated below.

<h3>How to illustrate the information?</h3>

From the information, c(x) = 200 - 7x + 0.345x². It should be noted that the domain is the set of x-values that are feasible.

The range is the set of possible results for c(x). They are the possible costs. You can derive this from the fact that c(x) is a parabola and you can draw it, for which you can find the vertex of the parabola, the roots, the y-intercept, the shape.

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

If the functions do 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 from 164.5 to infinity, limited to the solution for x = positive integers.

Help please !!!!!!!!!!!!!!

To start, we're given the range that x lies in: from -1 to 4. We know from the fact that $-1 \leq x$ that -1 will be <em /><em>included</em> in that range, so we mark -1 on the number line with a solid circle. We also know from $x\ \textless \ 4$ that, while x can be any value <em>up to</em> 4, it does not <em>include </em>4. We indicate this by drawing a hollow circle around 4 on the number line. Since x can be <em>any value within this range</em>, we make that fact clear by drawing a bold line between the points -1 and 4 on the number line. I've attached an image of what our final graph would look like.
