Thanks Reiny :D
A= P(1+r/n)^n*t for instance A=10000(1+0.05/1)^1*10 A= 10000(1.05)^10 a= 10000(1.628895) A= 16288.95
Sorry the equation is wrong it should be W(t)=5 (t-10(t-20)+4500
sorry I have messed up with the second point value hahahhaha the equation will change to 25x^2-750x+10000 just follow the above steps and u will get the right answer sorry
B) step 1: substitute points to write to linear equations y= ax^2+bx+c the three points are (0,10000) (3,7595) (6,6400) 7595= a3^2+b x3+10000 7595=9a+3b+10000 -10000 -10000 -2405=9a+3b Equation (1) 6400=a(6^2)+6 xb+10000 6400=36a+6b+10000 -10000 -10000
Thanks Reiny
Thank you! I got the other parts, but I still cant get part b. Isn't it sqrt(26/1.5) and the answer multiplied by 2 to get tension, but its giving me wrong. I don't know why!
Would this help these two points were given on the graph illustrated with this question (-7,0) & (1,0) thnks for the help
Thank you I really appreciate your help :)
