Simplify the Fractional Expression:
(1-(x+h)/(2+(x+h))-((1-x)
/(2+x))/h (the whole thing is divided by h)

what would the answer be to this problem?
6+y=2

Can you figure it out and tell me how you got it?

this is what i got as an answer...

6 + y = 2
-6 - 6
y = -4

Hi everyone, I was wondering what the derivative of m^m is with respect to m, it seems you could use the product rule and get

d(m) * m^(m-1) + m * d(m^(m-1))
1 * m^(m-1) + m * (d(m) * m^(m-2) + m * d(m^(m-2)))
etc.

which would be just m^m again. But this makes d(m^m) be the same as d(e^m), so that can't be right, can it?

One number is 6 more than another. If the sum of the smaller number number and 3 times the larger number is 34, find the two numbers.

I want to solve the problem below..

A gives B a start of 30 seconds in a km race and still beats him by 20 m. However, when he gives B a start of 35 seconds, they finish the race in a dead heat. How long does A take to run the km?

My Ans:
------------

Lets read the first statement:

"......A gives B a start of 30 seconds in a km race and still beats him by 20 m....."

this means , if B reaches 980 mt in t1 sec , A will reach 1000 mt in t1-35 sec.


Now lets read the next statement , it says ..

"...when he gives B a start of 35 seconds, they finish the race in a dead heat. ...."

this implies, If B reaches 1000 mt in t2 sec , then A takes t2-35 sec to cover the same 1000 mt.


so, I have got two conclusion from two statements .

now , what to do ?

Question is asking,

How long does A take to run the km?

Kindly,please DONT give me the soln .

please give me some hints so that i can solve it .

do u think , my above conclusion is correct ?

I am stuck .plz give hints

Given that sinθ = 4sin(θ -60°), show that

(2√3)cosθ = sinθ

Hence find the value of θ such that 0° < θ < 180°

The answer is 74 if that helps

Thanks alot

First of all I will type the question and then explain what my problem is.

A 41 m guy wire is attached to the top of a 34.6 m antenna and to a point on the ground. How far is the point on the ground from the base of the antenna, and what angle does the guy wire make with the ground?

I found that the point from the ground to the base of the antenna is 22 m, which according to my book is correct. Now, I know there is a 90 degree angle in there, but I'm confused as to how to find the other angles since no other angles were given. Can someone please explain to me how to do this?

In this:

angle BCD=140degrees
AB=AC=AD=8
calculate BD

Please show me the way.
Please don't use Cosine Law because this question is in the part of the book that is a lot before the cosine law and there should be a solution without it.
