1) +C
2)a=1/16
3) a2 = 2k
a3 = k+1/2
k=17/6
4) d=6
10316 total
5) x=3 and x=-1
6) (x-4)^2+3
Minimum point at (4,3) intercept at (0,19)
PQ : 4sqrt(17) units
7)
8) 5x-4y-49=0
Area = 369/10
9) line theough (0,C)
Asymptote at y= 5
equate and disciminant greater than 0
c<5-2sqrt(3) and c> 5+sqrt(3)
10) k = 75
c = 5/2
just differentiate
x = -5/3
