The answer is 53
arctan(1/x)
that's the most I can do
It'll be 1- P (exactly 0,1 or 2 correct)
P(0)=0.8^6
P(1)=6C1×0.2×0.8^5
P (2)=6C2×0.2^2×0.8^4
Add those together and subtract the answer from 1.
There's no question?
Assuming your question is when A(t) would be discontinuous, the answer is 0
A(t) would only be discontinuous at 0
Actually, cosx = 0 at 90, not 180
the sinx is right though
It's not a valid equation because y does not exist
Gloria worked for 6 hours a day for 2 days at the bank and earned $114.24. How much did Gloria earn per hour?
6 x 2 =12 hours that Gloria worked for 2 days.
$114.24 / 12 =$9.52 Gloria earned per hour.
what is the unit price for a peice of cheese if 1.24 pounds costs $15.25
$15.25 / 1.24 =$12.30 cost per pound.
1.164164.. =1 164/999
Please give the next 3 terms of this sequence: 3, 17, 81, 255........etc. Thanks for help.
This is one possibility=3, 17, 81, 255, 623, 1,293, 2,397, 4,091, 6,555, 9,993.......etc.
Each term is generated as follows: a(n)=(n^4 - n + 3).
sec(-11pi/2)
I'll do it on the web2 calc and see what happens.....
sec(-11pi/2) = 1.047261908623317
Yes the is the web2 answer but it is NOT correct.

I'll message the owner of the site and see it he can fix or explain it.
for each question, there's a 1/5 chance to get it right. the chance you'll get 3 right is 1/125, 4 right is 1/625, 5 right is 1/3125, 5 right is 1/15625, and 6 right is 1/78125. Add those together and you'll get 0.0099968.
I think that's how you do it, but I could be wrong since I haven't done these in a while
\(sec(\frac{-11\pi}{2})\\ =sec(\frac{-12\pi}{2}+\frac{\pi}{2})\\ =sec(\frac{\pi}{2})\\ =\frac{1}{cos(90^\circ)}\\ =\frac{1}{0}\\ =undefined\)
Here is the formula for solving the question. (Ending height) - (beginning height) divided by minutes (4) so
0-1200/3. Your answer is -400
35/64
3.75
(t-2)/12 = 7/8
8(t-2) = 7(12)
8t - 16 = 84
8t = 100
t = 25/2 = 12.5
5 x 0.75 = $3.75
75 - 4/5
=375/5 - 4/5
= 371/5
7 - 4[4 - (2y - 4)]
= 7 - 4(4 - 2y + 4)
= 7 - 16 + 2y - 16
= 2y - 25
3344000000 / 289000000 ~= 11.57 times
