Soul I do half, you do half? Fair, yes?

ok Lets start.

1a) 0.27272727272727
b)-3
c)1/8
d) 1/3x^3 7x+C
e)(root2+root3)/2
f)6/7
g)$2.24

Question 2
a)I) 30x(3x^2+4)^4
II)x.cos(x+1) + sin(X+1)
III) xsec^2x-Tanx/x^2
b)I)1/2
II)1/4(e^12-1)
c)1/2In(x^2+3)+c

3a) 3 is on the line
b) 1/3
c) root10 units
d)They are perpendicular by m(ab).m(ac) =1/3(-3) = -1
e)2
f) 10
g) (0,3)
h) <
\ (meaning equal of lesser than) 3

Question 4

A i) 14
iI) 12
b)II common difference = -5
II)=195
c) 1/4
II) 21 1/3
d) vertex is 0, -3
II directrix is y=-5

5.
A)I) 36degrees
II) CD=ED
CB = EA
<C=<E = 108

Therefore (SAS)

III) 36
IV) x^2sin108+x^2(1-cos108) sin 36
b)I) A = 1,000,000
II) 0.034996
III The population iwll reach 2,000,000 after 19.8 years (slow eh?)

Done. =P

Have fun soul searcher with the rest. I have school now.

If you want just answers, then I'll type them out here. Full worked solutions, you'll have to ask me for those ones.

6. a) i) t = 1 and t = 5.4
ii) t = 3
iii) t = 5
iv) t = 8
b) i) x = 1/2
ii) x < 1/2
iii) pt. of inflection is at x = 1, concave up for x > 1
iv) I'm not drawing the graph out
v) As x approaches +infinity, y approaches 1

7. a) i) discriminant = 4 - 12k
ii) k < 1/3
b) i) y = -2x + 5pi/3 + 1, or in general form, 6x + 3y - 5pi - 3 = 0
ii) Maxium value = 3, Minimum value = -1
c) Let @ = theta
i) r = 8/(2+@)
ii) A = 32@/(@+2)²
iii) @ = 2, Area is 3.9422 cm²

8. a) i) R = 288 kg/s
ii) T = 10
iii) R = 2000rt3/9 kg/s
iv) A = 50t² - 1/4 * t⁴ + 300
v) Weight = 2176 kg
b) ii) V = 63pi/ln4 units³

9. a) x = 3, 4
b) Area = 3rt3/4 units²

10. a) i) P (win) = 7/18
ii) P (win at least once) = 203/824
b) i) 88 660
iii) $1 694 000
iv) The farmer should sell after 7 years
