v = 4t - 1/16*t^3
s = 2*t^2 - 1/64*t^4 + c
we know that when t=0, s=0 as well:
0 = 0 - 0 + c
c = 0
s = 2*t^2 - 1/64*t^4
Distance PQ is 64m, so we just have to find the value of t for which s=64:
64 = 2*t^2 - 1/64*t^4
t = +/-8
t = 8 (reject negative)

ii)
a = 4 - 3/16*t^2
a>0
4 - 3/16*t^2 > 0
and you do the rest

So you got that answer or I should explain it to you?

thnk u so much

mmm explain ??

 

[The Sarcastic Retard]

mmm explain ??

That integration question.

 

[The Sarcastic Retard]

mmm explain ??

Plus the thing I was talking about 90 is odd, I know it did not made any sense, I meant to say, ignore the zero and see the previous number(s) is/are even or odd. In case of 90, "9" is a odd number. In case of 180, "18" is a odd number.
SORRY FOR THE CONFUSIONS I MADE.

 

[ashcull14]

That integration question.

yes can u plzzzzzzzzzzz explain it???

please can someone solve it step by step?

To find the shaded area over here using integration is subtracting the integrals.
Sorry for bad writing.

Not sure what subjects you're taking so I'll just tag you in Maths because the probability of you taking it is high given your name and whatnot :3
You can then explore this forum for help in your other subjects C:
BEST OF LUCK ya cutie~

Plzz Zaq sarcastic & others... help me clear my concept.
When we are ask to find the acute angle b/w the lines/planes we need to use the formula N1 * N2= |N|*|N| cosQ/sinQ
My question is when to use SinQ and CosQ when we are using this formula to calculate the Q ?
