2010 AP Calculus AB Form A solutions.

Here are quick answers, let's check compare and check them.

**1.**

a) ∫(0→6) f(t) = 142.xxx cubic ft.

b) f(8) - g(8) = 48.417 - 108 = -59.58 cubic ft/hr

c) forgot already, but i did it

d) (∫(0→9) f(t)) - (125 + 108*2) = 26.335 cubic ft.

man it's so uncomfortable to write here, will add others later, or u guys can add too...

68Junior Member242Junior Member666Memberber1023, my bad. but the answer is still the same.Action52, on calculator part, where the intervals are given, you just can write the answer.2,429Senior Member****. I better get a 5 on this, or I'll be really mad. I was getting easy (and I mean easy) 5s on my practice tests, and in less time than allotted too.

666Member2.a) (E(7) - E(5)) / 7-5 = (21-13)/2 = 4 hund. of entries / hr.

b) ∫(0→8) E(t) = (2*4) + (3*13) + (2*21) + 23 = 112 hund. of entries

1/8(∫(0→8) E(t)) = 112/8 = 14 hund. of entries

1/8(∫(0→8) E(t)) represents the average number of entries, in hundreds, visitors deposited between noon - 8 PM.

c) 112 - (∫(8→12) P(t)) = 96 hund. of entries

d) at t=9.183; the max occurs

666Member2,429Senior Member68Junior Memberand b) should be trapezoidal rule

1,327Senior Member666MemberFallenAngel9, I'm not 100% sure about (C), but 99% sure about others.666Member666Member68Junior Member68Junior Memberam i retarded?

666Memberi really hope E(t) should be the rate.
