<p style="text-align:justify">The table shows some of the values, and each row of the table corresponds to a point on the line.</p>
<p style="text-align:justify">The graph is better than the table for filling in the gaps that occur in the table. But the table gives accurate values. The equation gives the means to determine exact values, but it requires you to do a calculation, while the graph values can be read off from the coordinates without having to do any calculations.</p>

What is the maximum revenue? (b) Profit is given as P(x)=R(x)−C(x). What is the profit function?
https://www.mathhomeworkanswers.org/248175/wristwatches-maximize-revenue-maximum-revenue-profit-function?show=248306#a248306
<p style="text-align:justify">(a) Rewrite:</p>
<p style="text-align:justify">R(x)=0.2((79/0.4)²-((79/0.4)²-79x/0.2+x²))=0.2((79/0.4)²-(x-79/0.4)²).</p>
<p style="text-align:justify">This rearrangement shows that when x=79/0.4, R(x) has a maximum value of 0.2(79/0.4)²=7801.25.</p>
<p style="text-align:justify">However, x=79/0.4=197.5 wrist watches. R(197)=R(198)=7801.20. The sale of 197 or 198 watches raises 7801.20 in revenue.</p>
<p style="text-align:justify">(b) P(x)=R(x)-C(x)=79x-0.2x²-32x-1650=47x-0.2x²-1650 is the profit function.</p>
<p style="text-align:justify">(c) To maximise profit x=47/0.4=117.5, so P(117)=P(118)=1111.20. 117 or 118 watches need to be sold.</p>
<p style="text-align:justify">(d) (a) doesn’t take into account the cost of making the watches. A quadratic function provides a target for the vender and allows the firm to plan production more efficiently. Also, it is easier to work out the target when a quadratic function applies. A linear equation cannot fix a target, because profit just increases with sales. More complex functions (polynomials with higher degree than 2) are more difficult to solve to find targets, and may generate more than one target.</p>

let a = number of adult tickets. end s = number of students tickets<br />

The westbound train travels at 16 mph slower than the eastbound train. if the two trains are 480 miles apart after 3 hours, what is the rate of the westbound train?
https://www.mathhomeworkanswers.org/248285/trains-westbound-travels-slower-eastbound-trains-westbound?show=248291#a248291
let w = weatbound train speed and e=eastbound train speed<br />
<br />
we know that w = e - 16 after three hours the westb train has covered a distance of 3(e -16) miles<br />
<br />
the eastb train has covered 3e distance the total of the distance covered by the trains is 480 miles<br />
<br />
so it will be 3(e - 16) + 3e = 480 ->> 3e-48+3e = 480 ->> 6e-48=480 dividing by 6 both sides we get<br />
<br />
e-8=80 that is e=88 mph and w=88-16=72 mph<br />

https://www.mathhomeworkanswers.org/248172/picture-japanese-rectangle-middle-picture-length-corresponds?show=248200#a248200
<p style="text-align: justify;">The official dimensions of the rectangular flag are: ratio of length to width is 3:2; the centre of the circle is the point of intersection of the diagonals of the rectangle and its diameter is 3/5 the width of the flag.
<br>
<br>
If 2x is the width, 3x is the length and the circle’s diameter is 6x/5.
<br>
<br>
1cm=2m for scaling.
<br>
<br>
6x/5=10m on the flag so x=50/6=25/3m. The dimensions of the actual flag are 25m by 50/3m.
<br>
<br>
On the scale version, these are 12.5cm and 25/3cm.</p>Word Problem Answershttps://www.mathhomeworkanswers.org/248172/picture-japanese-rectangle-middle-picture-length-corresponds?show=248200#a248200Thu, 16 Nov 2017 18:14:44 +0000Answered: area of a rectangle

The floor and 4 walls are all one foot thick. How many blocks are used to make the structure?
https://www.mathhomeworkanswers.org/247222/there-rectangular-structure-floor-walls-blocks-structure?show=248189#a248189
the floor area of the structure is 10 x 12 = 120 sq feet<br />
<br />
the two walls will be. 5 x 12 x 2 = 120 sq feet<br />
<br />
the other two walls will be 5 x 10 x 2. = 100 sq feet<br />
<br />
so the whole area of the structure will be 120 + 120 + 100 =. 340 sq feet<br />
<br />
since we use cubical blocks of 1 feet we will need 340 blocksGeometry Answershttps://www.mathhomeworkanswers.org/247222/there-rectangular-structure-floor-walls-blocks-structure?show=248189#a248189Thu, 16 Nov 2017 16:05:39 +0000Answered: What is the next number in the sequence 2-2-3-5-14-69?

The sales tax rate in pleasnattville is 8.75%. Find the total of the bill including tax and tip
https://www.mathhomeworkanswers.org/247082/kacey-friends-wanted-leave-pleasnattville-total-including?show=248185#a248185
lef b is the bill amount<br />
<br />
we have 8.75 % taxes this is b*.0875= .0875b<br />
<br />
we have a tip of 15% this is b*.150 = .150b<br />
<br />
so total payment = .0875b + .150b + b = b(.0875 + .150 + 1) = 1.2375b<br />

Total drive time is 6.6 hours. How long did each trip take?
https://www.mathhomeworkanswers.org/247130/driver-averages-return-trip-total-drive-time-hours-each-trip?show=248184#a248184
The driver run the one way trip a distance of 60*t1 miles ( let t1 is the time for the one way trip)<br />
<br />
so we have distance = 60t1<br />
<br />
on the wayback driver runs the same distance which is now 50t2 miles. (t2 is the time for return trip)<br />
<br />
since the distance is the same we have 60t1 = 50t2 (1) we know that t1 + t2 = 6.6 hours (2)<br />
<br />
from (2) we have t2 = 6.6 - t1 replacing this to (1) we get 60t1 = 50(6.6-t1) ->> 60t1=330-50t1 ->><br />
<br />
60t1 + 50t1 = 330 and 110t1 = 330 ->> t1=330/110 = 3 hours substituting where t1 in (2) we get<br />

https://www.mathhomeworkanswers.org/247371/find-the-following-arithmetic-sequence-for-what-value-of-tn?show=248181#a248181
the formula for finding the Tn is: Tn=T1 - 4(n-1) instead of T1 we can use the number 12 since this is the<br />
<br />
T1 for this sequence. So we will have Tn = 12 - 4(n-1) since the Tn we re trying to find out is -96 we will<br />
<br />
have: -96 = 12 - 4(n-1) ->> -96 = 12 - 4n + 4 and solving for n we have: -96 - 12 - 4 = -4n ->><br />
