|
Answer» x = √( 2 * √( 2 * √( 2 * √(2 * √( 2 * .....)))))=> x = √( 2 x )=> x²= 2 x=> x² - 2 x = 0=> x ( x - 2 ) = 0=> x = 0 or x - 2 = 0=> x = 0 , 2 .So x can be both, zero and two.There is no reason for zero not to be a root. Both, two and zero, satisfies the equation. |

By increasing the list price of a book by Rs. 10 a person can buy 10 less books forRs. 1,200. Find the original list price of the book |
|
Answer» Let original book price=X Number of books that can be bought in 1200 =1200/x Suppose price increases by 10. New price=x+10 No of books that can be bought in new price= 1200/(x+10) Now, this number is 10 less than the no of books that can be bought in 1200 at ‘x’ price. So, 1200/x= 1200/(x+10) + 10 Simplifying the above we get X^2 +30x -1200=0 x=-b+-√b^2-4acx=30+-√900+4800/2x=30 and -40ignoring -40 as number should be positive. So original book price is Rs 30 |

A cloth having an area of 165 m is shaped into the form of a conicaltent of radius 5 m. (i) How many students can sit in the tent if a student,on an average, occupies㊠on the ground? (ii) Find the volume ofies 5 m2 on the ground? () Fthe cone. |
|
Answer» Since we have given that Radius of conical tent = 5 m We need to find the "Number of students who can sit in the tent if a student occupies 5/7 m^2 on ground." So, we need to find the area of ground which is in shape of circle in case of cone. As we know that the base of cone is circle. So, Area of base of cone (ground) is given by πr^2 = 22/7 * 5 * 5 = 550/7 So, Number of student who can sit in the tent is given by = Area of base/(5/7) = (550/7)/(5/7) = 550/5 = 110 Hence, there are 110 students who can sit in the tent. Like my answer if you find it useful! |
