? what do you mean? like what exponent you could get through factoring? because.... factoring

64= 2 radical 8

8 = 3 radical 2

64 = 6 radical 2

or 2^6=64

... no. However, I do recall having to prove that 2+2=4 with mathmatics... it's a lot of work.

or 42, if you're looking for the answer to life, the universe, and everything. (but then you son't know the Question, do you?)

It means "empty set"  ....   or, if we're solving an equation, it indicates no solution

This is given by :

e

∫     1/x    dx

1

      e

ln x ]   =      ln(e)  - ln(1) =   1  -  0     =    1 sq unit

      1

Let's see where these curves intersect

10x = 2x^2

2x^2  - 10x  = 0

2x ( x - 5) = 0        setting each factor to 0, the intersect points are x = 0   and x = 5

So we have

    5

pi ∫    (10x)^2   - (2x^2)^2   dx     =

   0

   5

pi ∫  100x^2  - 4x^4   dx

  0

                                            5

pi  [ 100x^3 / 3    -   4x^5/5]           = 

                                            0

pi [ 100(5)^3/3  - 4(5)^5/5]  =  about 5235.99 cubic units

Express 173⅞% as a decimal

173 7/8%=173.875 / 100=1.73875 as a decimal=1 +591/800 as a mixed fraction.

V_cylinder =  pi * r^2 * h   =  pi * 4^2 * 32  = pi * 16 * 32  = about 1608.5 cu ft

2 + 2/5 =  12/5

So

12/5   / 18  =

(12/5 )  /  (18/1)  =

(12/5) * (1/18)  =

12 / 90  =

4/30  =

2/15

We can use the Law of Sines  to solve this

sin(42) / 22  = sin B / 12

sin B  = 12 sin(42 )/ 22

arcsin [ 12sin(42)/22]  = B  = about 21.41°

Since we have a SSA  situation, we have to check to see if we have another triangle

So....the other possibility for B  = [180 - 21.41] °  = 158.59°

But, this would mean the sum of angles A  and B  would exceed 180°  ....so, we only have one triangle

(2.4*10^4)*(5.3*10^3)  =

2.4 * 5.3   *  10^4 * 10^3 =

12.72    *  10^7  =

1.272 * 10^8

Break it into 6 triangles and work it out that way.  :)

if pounds are anything like americain money, you would recieve 1.36 back

127

How about you answer them yourself and we will tell you if you get them right :)

Хорошо, спасибо

I answered before I realized that this was a repeat question - please do not do this again.

A circular oil slick has a diameter of 1 km. The newspaper reported an area of more than 1 km squared. is the newspaper correct?

The area of a circle is pi*radius squared     and the radius is 1/2 a km

\(area=\pi*r^2\\ area=\pi*0.5^2\\ area=\pi*0.25\\ area\approx 0.785km^2 \)

So no the oil slick is smaller than 1km^2

The possibilities (where g = good and b = bad) are:

gg = 6/10*5/9 =  1/3

gb = 6/10*4/9 = 4/15

bg = 4/10*6/9 = 4/15

So, given that one of the pair is g, the probability that you have gg is  (1/3) / (1/3 + 4/15 + 4/15) = 5/13 ≈ 0.385

Thx. i wasnt sure if any1 would answer but sure enough they did! i did work it out but its good to know a site that actually answers correctly. once again thx.

Thank you!!!!!!!

4^13 =  67108864

No......

If the diameter  was 1 km the radius  = (1/2) km

And the area would be

pi * r^2   =   pi * (1/2   km)^2   =  pi / 4  km^2     =  about pi/4 = 0.785 km^2
