X^3+ y^3 = 91. x^2- xy + y2 = 13. Find the values of x and y. |
|
Answer» Answer: Step-by-step explanation: The first thing anyone would try is x=3,y=4 , which checks. It will be useful to have one root so we can turn our cubic equation into a QUADRATIC one. Proceeding like Mr. Pradeep, let s=x+y . I USE s because my t s look like + signs. Of course my s looks like a 5 ... anyway. s2=(x+y)2=x2+2XY+y2=25+2xy 2xy=s2−25 s3=(x+y)3=x3+3x2y+3y2x+y3=91+3xy(x+y)=91+3sxy 0=−2s3+3s(2xy)+182= −2s3+3s(s2−25)+182=s3−75s+182 Since 3,4 is a solution, s=3+4=7 must be a root of this equation, so we can factor out (s−7). Doing the long division, we get s3−75s+182=(s−7)(s2+7s−26)=0 The THREE roots are s=7 and s=−7±317√2 . The latter two are real and real ugly. I can see why Mr. Pradeep resorted to decimal approximations. Now that we have s , we can go back and solve for x and y . Let's do it symbolically first. We have s=x+y , so y=s−x , and 2xy=s2−25 . 2x(s−x)=s2−25 0=2x2−2sx+(s2−25) x=14(2S±(2s)2−4(−2)(s2−25)−−−−−−−−−−−−−−−−−−√)=12(s±50−s2−−−−−−√) So for s=7 we have x=12(7±50−72−−−−−−√)=12(7±1) . x=3 or x=4 . Note that when one is x the other is y . Now we're left with the messier parts. I'm busy now so I will come back to those. 10 days later and I'm back. This is messy, but let's get those other roots. We have s=−7±317√2 and x=12(s±50−s2−−−−−−√) That's enough to calculate the answers, but I was after the closed form. It doesn't simplify down much, but we can make progress. (2s)2=49+9⋅17−±2⋅2117−−√=202−±4217−−√ 200−4s2=−2±4217−−√ We're going to have to take the square root of that. Let's first focus on the s with the plus sign, which gives a positive 200−4s2 . 250−s2−−−−−−√=200−4s2−−−−−−−−√=−2+4217−−√−−−−−−−−−−√ x=12(s±50−s2−−−−−−√) x= 14(−7+317−−√±−2+4217−−√−−−−−−−−−−√) Simple. These give two more real solutions, x≈4.613 and x≈−1.928. Again, each is the other's y . What about that complex solution? That's from s=−7−317√2 x= 14(−7−317−−√±i2+4217−−√−−−−−−−−−√) Those are two more complex roots, x≈−4.842±3.309i OK, we found six roots. They come as three x,y pairs that you can swap due to the symmetry of the problem. |

10. The Total surface area of cuboid 758 sq. cm has length and breadth14cm and 11 cmrespectively. Find the height of the cuboid? |
|
Answer» Step-by-step explanation: SURFACE AREA of cuboid =2(lb+bh+HL) Surface Area of cuboid = 758 sq. cm ( given ) length = 14 cm breadth = 11 cm height = ? cm ATQ 2(lb+bh+hl) = 758 lb + bh + hl = 758/2 lb + bh + hl = 379 14 x 11 + 11h + 14 h = 379 154 + 25h = 379 25 h = 379 - 154
25h = 225 h = 225/25 h = 45/5 h = 9 cms.
