x^2 + 12x + k   

Here is the way to find this.......take 1/2 of the coefficient on x   = (1/2) * 12   = 6

Now.....square this  = 36      and this is "k".....this produces a perfect square trinomial because

x^2 + 12x + 36    factors as (x + 6) (x + 6)   =  (x + 6)^2

Decay Constant= 1.2*10^-4years^-1 
What is the decay contant?

Decay constant is used to determine the half-life of a radioactive element and comes from this expression:

A=Ao.e^(kt), where A=amount remaining after t time, Ao=initial amount, k=constant of decay(which is always a negative number). You can figure the k by using this simple formula: k=ln(1/2) / half-life of the radioactive element. Since you have the decay constant, we can easily figure out the half-life of the radioactive element in your example: ln(1/2) / (1.2*10^-4)=~5,776 years.

-5[2y - 3(y + 5)]     simplify inside the brackets

-5 [ 2y - 3y - 15 ]    

-5 [ -1y -15 ]     distribute the -5 over the terms inside the brackets

5y + 75

The height after the nth bounce is given by :

125 (2/5) ^{n - 1}     so.....sfter the 4th bounce, we have

125 (2/5) ^{4 -1}   =

125 (2/5) ³   =

125 (8 / 125)  =

8 inches

Lol! 676, right?

676x4=2704!

i posted this question!

50+2

chuck yeah

if my d**k, hurts do i cut it off

Try realcalc..... the free one is good, for a couple of bucks you can skip the ads.

radical x over radical cubed x multiplied by 1 over 4

\(\frac{\sqrt{x}}{\sqrt{x^3}}*\frac{1}{4}\\ =\frac{x^{0.5}}{x^{1.5}}*\frac{1}{4}\\ =\frac{1}{x^{1.5-0.5}}*\frac{1}{4}\\ =\frac{1}{x^{1}}*\frac{1}{4}\\ =\frac{1}{4x} \)

Because most calculators cannot handle very large numbers like that. Do you realize how big a number Pi^(999 x 10^12) is? It is : 5.25408285316 x 10^496,652,722,821,439

This number is so big, that if you were to write it, in small print, on long piece of paper, your paper would have to stretch from here to the Sun, some 3.3 times!!!!!!.

sin(x) = 33/80

x = sin^-1(33/80) = 24.36°

or x = asin(33/80) = 24.36°  

csc(x) = 1/sin(x)

( sin(x) )^-1 = 1/sin(x)   but   sin^-1(x) = arcsine(x)

.

Thanks ALAN   :DD

That makes PERFECT sense.      

Chris,  why didn't you explain it to me like that !!    LOL             

This question does not make sense.

explain for me please

sin^-1 is not invers of the sin?

csc=1/sin

sin^-1=csc?

sin(x)=33/80 

x=?

explain for me please

sin^-1 is not invers of the sin?

csc=1/sin

sin^-1=csc?

No.  sin^-1 is arcsine.  That is, it's the angle whose sin is ...

360 + (-20.5) =
