These come in two varieties:
(i) (a b), for some distinct a, b in {1, 2, 3, 4}.
There are 4 choices for a and 3 choices for b
Remembering that (a b) = (b a), there are (4 * 3)/2 = 6 such elements.

K, I dont get this problem 7 - 5u = -43, please help (It cant be a decimal or fraction) and if possible can you help me on these too? 14 + 4x = 38and-40 = 8 - 6s-Add 43 to both sides to get 50 - 5u =
so i got it to this point: sqrt((-16x^2+144)/9)=y and that is looking pretty nasty when i derive it and simplify it and im not getting the same thing as when i implicitly differentiate it-9y^2 = 144 -
In a shipment of 13 room air conditioners, there are 4 with defective thermostats. Two air conditioners will be selected at random and inspected one after another. Find the exact probability that:

Can you solve this integral e^2x / (1+e^2x)?-When you see almost the same thing in the denominator, ln is a good thing to try:
d/dx ln(1 + e^2x) = 2e^2x / (1+ e^2x)
=> d/dx (1/2) ln(1 + e^2x) = e^2x
Okay so this is on probability but i dont get what i have to do here.You pick two marbles from the bag at the left (4 blues,3 reds,2 greens). You pick the second one without replacing the first one. F
is
100^50
-------------------
(2^102) (5^98)
100^-149?-...the correct answer is:
25/4
you should show your work !
denominator:(2^102) = (2^98) * (2^4)
so, (2^4) * (2^98) * (5^98) = (2^4) * (10^9
Evaluate teh function at the specified value of the independent variable and simplify.
q(p)=5p+1q(1.5)
Please answer it and explain how to do it, im having alot of troubles in Pre-calc..-You just tak
y= -12x
y at -2 = -12(-2)
y at -2 = 24
so the slope at x = -2 is 24
y-y1=m(x-x1)
y+27=24(x+2)
y=24x+48-27
y=24x+21-rewrite equation so it follow y=mx+b which would be y=-6x^2-3
the slope m=-6
use poi
Say youre given a problem such as:
77^2 - 73^2 = ?
Well, the shortcut that I learned for this is:
4(77 + 73) = 600
Thus,
77^2 - 73^2 = 600
But... whats the math behind that?
a^2 + b^2 = c
