haha, my prof noted that i we just copy it. theres an example mam for that. hope you could help me. :/

Hi Kath,

I think that English is not your first language, although I could be wrong.   :)

What do you mean by "solve the following points"  ????

There is nothing to solve.

You obviously want a distance but which distance do you want?

If you want the distance of each point to the origin (0,0) then it is exactly the same method as we used in your last question.

If that is what you want then give it a go by yourself, you can post your answers and I will check them if you want.  :))

If that is not what you want then try and tell me what you do really want.  :)

Yes it is just the Pythagorean theorem :))

I mam, i already answered the 3. i think it goes to the formula of phytagoreas. thanks much. one last question mam? :)

ok well you just want the distance of the point from the origin.

I already did the first one.

Draw a sketch on a number plane to get the idea.

2. y=-5, r=13

This is saying that the hypotenuse is 13 and the y direction is -5 units

so

\(x^2=13^2-(-5)^2\qquad \mbox{ it is minus cause you are finding the short side of a right angled triangle}\\ x^2=169-25\\ x^2=144\\ x=+12\quad or \quad x=-12 \)

3.  x=3, r=5

\(x^2=25-9\\ x^2=16\\ x=\pm4\)

Think about it and if you still do not understand then let me know :))

Hi mam, this is the sample that our prof gave

I am not at all sure what you mean Kathh22 :(

1. x=3, y=4

I don't think this is what you want but.....

\(28y+6=50\)

\(28y+6-6=50-6\)

\(28y=44\)

\(\frac{28y}{28}=\frac{44}{28}\)

\(y=\frac{44}{28}\)

\(y=\frac{44}{28}\frac{÷}{÷}\frac{4}{4}\)

\(y=11/7\)

\(y≈ 1.5714285714285714\)

Total cost =200,000 * x

  U=1/2*kx^2, solve for x

  x = ±(sqrt(2) sqrt(U))/sqrt(k)

F=[G*M*m] / r^2, solve for r

r = ±(sqrt(G) sqrt(m) sqrt(M))/sqrt(F)

Hello Guest!

The function, y(r)=2.76r , is used to convert Russian rubles in Japanese yen, and the function, p(y)=0.16y , is used to convert Japanese yen into Mexican pesos. Use composition of functions to find the equivalent value of 2000 Russian rubles in Mexican pesos. Round the product of the decimal numbers in the composite function to the nearest hundredth.

2000r * (y/2.76r) * (p/0,16y) = 4528.99p

If you have one hectare of land, then that means you have:

100 meters x 100 meters =10,000 square meters. And if want to plant your lemon trees 3 meters apart in every direction, then you have: 3 meters x 3 meters =9 square meters for each tree. So then, all you have to do is to divide your hectare into a grid in such a way as to have horizontal and vertical rows and columns of trees, if you were to look at them from above.

And to plant them in that manner, all you need is to divide your 10,000 meters by 9 meters that each tree requires and you will have: 10,000 / 9 =1,111 total trees or about 33 trees in each row  and column up and down and across your entire property.

How do I put 150,000/100,000^1/3-1

[150,000 / 100,0000]^1/3 - 1 Is this what you want?, if yes then we have:

1.5^1/3 - 1 =1.1447142425533318678080422119397 - 1=0.14471424255333186780804221193968.

Also, all the three combined payments for the first year can be directly calculated using a familiar TVM formula, which we can plug into Wolfram/Alpha, and which gives an instantaneous result:

http://www.wolframalpha.com/input/?i=1,213,592.233*((1+%2B+0.04854368932)%5E25+%2F+((1+%2B0.04854368932)%5E25+-+1))+*+1.03

There are a number of ways of solving this problem. I will use the simplest of them as follows:

First, will find the net interest rate by: 1.08 / 1.03 =4.85%. Using this rate, will find the PV of the rarios

of disbursements, which are as follows: 1 + 1.5 + 3 =5.5, using the common TVM formula:

PV=P{[1 + R]^N - 1.[1 + R]^-N} R^-1=5.5{[1+0.0485]^25 - 1.[1+0.0485]^-25}. 0.0485^-1=78.66089675

Now, we simply divide $25 million by this last number=$25,000,000 / 78.66089675=$317,819.92. This is the 1st. payment to University A. The only adjustment we have to make is to index it to inflation rate:

$317,819.92 x 1.03 =$327,354.52. So, we have:

1)  $327,354.52- First annual payment to University A.

2) $327,354.52 x 1.5 =$491,031.78-First payment to University B.

3) $491,031.78 x 2    =$982,063.56-First payment to University C.

4)$1,800,449.86-Is the total first year payments to all 3 Universities. These individual payments will be indexed by 3% inflation rate every year thereafter for 25 years.

Let N be the cost of the meal before the tip and we have that :

N * 1.15 = 27.60     divide both sides by 1.15

N = 27.60 / 1.15 =   24.00

(x + 4)² = 77²       using the square root property, we have

x +  4   =  ± 77

So either

x + 4 =  77     and x = 73

or

x + 4 = -77 and x = -81

So....the answers are   x = 73   and x = -81

We have these points on the total cost graph (0, 100000)   and (1000, 200000).....the slope of this line =

[200000 - 100000] / [ 1000 - 0]  =    100000/1000   = 100

So....the equation  of the line can be found using the point-slope form :

y - 100000  = 100[x - 0]      simplify

y = 100x + 1000000

tan x = √3

We can do this in several ways.......one way is to take the tangent inverse [arctan] of √3.......so we have

arctan √3   =  60°  =  pi/3

This is  also true at 240°  =  4pi/3

2 x 3 1/6

4 x 2/3

1 x 4 2/3

.3 x 5/6

sum of this and you'll be rite

Solve for w:
204201.-w = 221055.

Subtract 204201. from both sides:
(204201.-204201.)-w = 221055.-204201.

204201.-204201. = 0:
-w = 221055.-204201.

221055.-204201. = 16854.1:
-w = 16854.1

Multiply both sides of -w = 16854.1 by -1:
(-w)/(-1) = -16854.1

(-1)/(-1) = 1:
Answer: |  w = -16854.1

The function  f(x)  =  tan( pi·x/2 )  is discontinuous at  pi/2 + k·pi  for all integer values of  k  (including negatives).

These discontinuities are NOT removable because the  y-value  approaches  + infinity  from the left  and  - infinity  from the right at each of these discontinuities.

Yes Alan, I know this, but the answer must be 100x , how did he find the answer 100000 + 100x
