This will help!

I am glad that you like it.  It does do a lot of things!

5y=2x-10 (x-int)(y=0) (y-int)(x=0)

Yes the x int is where y=0

5*0=2x-10

0=2x-10

10=2x

x=5    That is your x intercept

and

y intercept is where x=0

5y=2*0-10

5y=0-10

5y=-10

y=-2   That is your y intercept.       

Do it on the site calc on the home page :)

$$\sqrt[3]{(9+4 \sqrt 5}+\sqrt[3]{(9-4 \sqrt 5} = 3$$

Umm I do not know - I'll have to think about this one!

cos(0) = 1

So

[cos(0)]^2  = [cos(0)] * [cos(0)] = 1 * 1 = 1  ....!!!

Assuming we're in degrees, we have

sin(345) = sin(300 + 45)....and using sin(A + B) = sinAcosB + sinBcosA, we have

sin300cos45 + sin45cos300 =

(-√3/2)(1/√2) + (1/√2)(1/2) =

-√3/ (2√2) + 1/(2√2) =

[ 1 - √3 ] / (2√2)     and rationalizing the denominator, we have

√2 [ 1 - √3] / 4 =

(√2 - √6) / 4

Thank you Alan 

Thanks Chris 

I don't know if all those anon posts are from the same person.  

It would be easier if your joined up and then I would know :)

Anyway I'll talk about it a little more

If there are no brackets then you DO NOT put any in.  The answer will be negative.

$$\\-6^2=-36\\
-x^2<0$$

The negative sign is ONLY squared if the brackets are there in the original question.

$$(-7)^2=49

(-x)^2>0 \qquad $always$$$

Does that help?

Thanks...it took me forever to write that one out !!!

Ah...just as I suspected !!  (LOL!!!)

Great answer Chris :)

Thanks Chris,

I can't take too much credit - It was a straight copy off the net :)

Sorry...i meant "Googolplex"  !!!!

Assuming compound interest and one compounding per year, we have

500( 1 +. 042)³   ≈ £565.68

That is the number.  It is called a googloplex.

But if you want the numbers with a 1 and lots of zeros, the answer is no. There are more zeros than your brain or mine can make any sense of.   

001.

Use v = u + at  (assuming constant acceleration applied by the bowstring).

127 = 0 + 139t

t = 127/139 s

$${\mathtt{t}} = {\frac{{\mathtt{127}}}{{\mathtt{139}}}} \Rightarrow {\mathtt{t}} = {\mathtt{0.913\: \!669\: \!064\: \!748\: \!201\: \!4}}$$

t ≈ 0.9137 s

002.

Since it doesn't accelerate after it leaves the bow and there is nothing to retard it in space, it continues with the same speed: v = 127 m/s.

003.

distance = speed*time

distance = 127*3.5 m

$${\mathtt{distance}} = {\mathtt{127}}{\mathtt{\,\times\,}}{\mathtt{3.5}} \Rightarrow {\mathtt{distance}} = {\mathtt{444.5}}$$

distance = 444.5m

.

I believe you want this....  (243)^(1/4).....you can put it straight into the on-site calculator in this form and get your answer....

Nice graphic, Melody......how did you do that ??? (Was it a straight copy ??)

I believe what you have written is known as a "Googol"....We couldn't write this number out, even if we wanted to!!!  (There isn't enough time in our lives to do so, nor physical space in the Universe to do so !!!......)

Edit......"Googolplex"....thanks, Melody

Do you want to know the weights of these things?

Are they made of lead or clay or styrophom. It makes a difference  

There is no formula - you just have to understand the question.
