Answer:
1,300
Step-by-step explanation:
1256, if something is more than 5 then it goes up but if it's 4 or lower it goes down so 1256 rounded up to the nearest hundredth is 1300.
The definite integral from x=2 to x=k of (6x-5) is
x^2
6*------- - 5x, [2,k] or 3[ k^2 -5k] - 3 [ 2^2 - 5(2) ]
2 or
3[k^2 - 5k] - 3[4-10] = 10 (as given)
3k^2 -15k + 18 = 10, or
3k^2 - 15k + 8 = 0
This is a quadratic equation; solve it using the quadratic formula:
-(-15) plus or minus sqrt( [-15]^2 - 4(3)(8) )
k = ------------------------------------------------------------
6
15 plus or minus 26.36
= ------------------------------------
6
