Answer is 0 because anything to the power of one is 0 

whatz the meaning of 2nd power?????

plz tell me i dont know that.....

log (3/4)^x  = log 5

x log (3/4)   = log 5

x                 = log 5/(log (3/4))

x                 = log 5/ [log 3 - log 4]

x                 =0.6989 /(0.4771 - 0.6020)

x                 = 0.6989 /-0.1249

x                 = -5.595676541232986389111289031225

x                 = -5.5957//

7(a+6)

7*a + 7*6

7a +42

only we can solve this problem

4/3*3.14*(0.025^3)

=4/3 *3.14*0.000015625

=6.5416666666666666666666666666667

=6.54167//

thatz the answer..

1^6/6^6

=1/(6^2)^3

=1/36^3

=1/46656

=2.1433470507544581618655692729767

=2.143//

thatz the answer......

You already have the method Melody, you used it in your earlier post.

To illustrate what's going on here, consider the,  integrand cos(x).sin^3(x).

We can integrate that in, at least, two different ways.

We can integrate it directly as sin^4(x)/4  or we can use the trig identity sin^2 = 1 - cos^2 to get

cos(x)(1-cos^2(x))sin(x) = cos(x)sin(x) - cos^3(x).sin(x) which integrates to -cos^2(x)/2 + cos^4(x)/4.

The problem we are discussing is dealt with in exactly the same way except that the functions are cosec and cot.

Come back if you need further details.

$${\mathtt{1\,000\,000\,000}}{\mathtt{\,\times\,}}{\mathtt{60}} = {\mathtt{60\,000\,000\,000}}$$

558/3

5+5+8 =18 =1+8 =9

so we can 558 divide by 3

Probability of Sergio's number being greater than Tina's sum is:

Tina's sum   Tina's Probability  Probability of Sergio's number being greater    Product of probabilities

       3                   1/10                           7/10                                                        7/100

       4                   1/10                           6/10                                                        6/100

       5                   2/10                           5/10                                                      10/100

       6                   2/10                           4/10                                                        8/100

       7                   2/10                           3/10                                                        6/100

       8                   1/10                           2/10                                                        2/100

       9                   1/10                           1/10                                                        1/100

Add up all the probabilities in the last column

(7+6+10+8+6+2+1)/100  = 40/100

So probability of Sergio's number being greater than the sum of Tina's two numbers is 0.4

7.25/26.2

=7.25*10/26.2*10

=72.5/262

=0.27671755725190839694656488549618

=0.2767//

thatz the answer

2*pi*r =154

pi* r    = 154/2

pi * r   = 77

22/7 * r = 77

r           = 77* 7/22

r           =  14/2

r           = 7//

so that. radious of that circle is 7 cm//

=2+2/500000000=   $${\mathtt{2}}{\mathtt{\,\small\textbf+\,}}{\frac{{\mathtt{2}}}{{\mathtt{500\,000\,000}}}} = {\mathtt{2.000\: \!000\: \!004}}$$

u=119,   v=233,   a=17.1,   s=?

You need a formula with u,v,a and s    so use [4]

$$\\v^2=u^2+2as\\
233^2=119^2+2*17.1*s\\
233^2-119^2=2*17.1*s\\
(233^2-119^2)/(2*17.1)=s\\$$

$${\frac{\left({{\mathtt{233}}}^{{\mathtt{2}}}{\mathtt{\,-\,}}{{\mathtt{119}}}^{{\mathtt{2}}}\right)}{\left({\mathtt{2}}{\mathtt{\,\times\,}}{\mathtt{17.1}}\right)}} = {\frac{{\mathtt{3\,520}}}{{\mathtt{3}}}} = {\mathtt{1\,173.333\: \!333\: \!333\: \!333\: \!333\: \!3}}$$

displacement = 1173.3 m

Note: you can also do this with calculus. :)

FORMULAS

assuming it is in dollars

7(a+6)=7*a + 7*6 = ??

If c=12, m angle A=80, and m angle c=40, find a

The sine rule

We can use the sine rule to find the size of an angle or length of a side.

The only "excluded" values are those that make the denominator = 0

So we have

2n^2 - 7n - 4 = 0     factor

(2n +1)(n - 4)  = 0    and setting both factors to 0, we find that the "excluded" values are n = -1/2 and n  = 4 

Gamoon, sorry for what i had say. I wrotw this question for a chat with a few friends, so u can chat, but I think that we can' t help u... Sorry...

Thanks, Sasini......

2865000000000000

=2.865 * 10^15

2x + 4

=2(x +2)

we can solve this like that.

yes, it's exactly what you wrote and i found the answer. f(2) = -4/3

in this question, you should imagine that x+(1/x) = -1/2 although this is not possible.

Thanks.

There's nothing to "simplify".....this won't factor, but we can use the onsite solver (with a little help from the quadratic formula) to find the solutions......they will be "real" ones....

$${{\mathtt{x}}}^{{\mathtt{2}}}{\mathtt{\,-\,}}{\mathtt{9}}{\mathtt{\,\times\,}}{\mathtt{x}}{\mathtt{\,\small\textbf+\,}}{\mathtt{1}} = {\mathtt{0}} \Rightarrow \left\{ \begin{array}{l}{\mathtt{x}} = {\mathtt{\,-\,}}{\frac{\left({\sqrt{{\mathtt{77}}}}{\mathtt{\,-\,}}{\mathtt{9}}\right)}{{\mathtt{2}}}}\\
