How would you write this? Sorry.

has a slope of _______ ?

By using natural log.

ln1.167=100000ulne   (lne=1)

ln1.167/100000=u

u=0.00000154436.... approx

Thank you, YourAssassin.....that answer was very helpful....!!!

simultaneous equations...

I would start this off by making x or y the subject.

So 1st Equation now equals x=13-2y

Now i sub equation 1 into equation 2

So -2(13-2y)-3y=-18

-26-4y-3y=-18

7y=-8

y=-8/7

Then sub the y value into equation 1 to get x value

x+2(-8/7)=13

x-16/7=13

x=107/7

1)hypotenuse is 12, an angle is 12 degrees, find the side opposite the angle

Use the sine here...the opposite side is ....   12*sin(12)

2) 2)hypotenuse is 32, an angle is 65 degrees, find the side adjacent to the angle

Here, we can use the cosine   ...... the adjacent side =   32*cos(65)

You should be able to take it from there....

Rules of indicies: A^N X A^M = A^N+M

Therefore x ^2/7 times x ^ 3/14 = x^1/2

Remember the exponent law that says  a^m * a^n  = a^(m + n)...so we have..

x^(2/7) * x^(3/14) = x ^(2/7 + 3/14) = x^(4/14 + 3/14) = x^(7/14) = x^(1/2)

The forumula for this is Total amount at the start(1+Percentage/100)^number of years

4500(1+13/100)^13 = 22041.04996

Therefore at the end of 13 years a person will have 22041.05 dolla

This question makes no sense....

f(x) = 1 / √(9 - x^2)

Since the denominator can't  = 0 , x cannot be 3 or -3.  And since we can't take the square root of a negative number, any x values < -3 or > 3 make the square root non-real

So....the domain is  just (-3, 3)

The range is a little trickier.....as "small" as y can be is when x = 0 ...and this is 1/3....and as x approaches either -3 or 3 in the domain, y approaches infimity...so, the range is [1/3, ∞)

3.5x + 7 = 1/2x - 6 (subtract 1/2x on both sides)

3x + 7 = -6   (subtract 7 on both sides)

3x = -13     (divide by 3 on both sides)

x = 4.333333333.....(you get the point :)

i know there is already answer, but i thought it would be helpful if i listed the steps

90877+33 would be 90910..

why didnt you use a calculator for such a simple addition problem?

5.297x10 in standard notation would be 52.97

Example: 7qr-qr=6qr

qr really means 1qr so you would subtract that numbers and then add the variable in.

Example: 9e - 5e = 4e

Here's one way...using the first 7 integers

(7^3 - 6^3) + (4^3 - 5^3) - (3 * 2 * 1)

(127) - (61) - (6) =

66 - 6   =

60

(I'm sure someone else will come up with something more elegant....!!!)

3x+7=-6

3x=-13

x=-13/3

9+10+8+11+7+12+3=60

a)  We would have [ -4x + 4 ] / [x -3]

We only need to worry about the values that  make the denominator = 0   ..so we have

x^2 + 6x + 8 = 0     factor

(x + 4) (x + 2)  = 0

And setting each factor to ), we see that X = -4  and x = -2 make the denominator 0....so the domain is....all x's except -4 and -2

32²  =  1024

But, if you meant √(32), this can be done two ways:

   ---   first, using a calculator:  √(32)  ≈  5.65685, so, rounded to the nearest whole number  ≈  6

   ---  second way, without a calculator:  5² = 25 (too small)   and  6² = 36 (too large), but 32 is closer to 36              than it is to 25, so choose 6 (but this can get tricky) 

As an example:   108     45     480

First, factor each number, using exponents:  

        108  =  2² · 3³          45  =  3² · 5          480  =  2⁵ · 3 · 5

Now, take each factor, with its largest exponent.

   ---   the largest exponent on 2 is 5, so use 2⁵

   ---   the largest exponent on 3 is 3, so use 3³

   ---   the largest exponent on 5 is 1, so use 5

Multiply these together:     2⁵  · 3³ · 5   =   4320

Hey...that's right....I forgot...!!!.....I'll stand pat this week.....!!!

Let  x  equal 1.7333333...

To make it easier, get the non-repeating part to the left side of the decimal by multiplying by 10:     

     10x   =   17.33333...

Since the repeating part has only one digit repeating (just the 3), multiply this last answer by 10 to get:

    100x  =  173.3333....

Place the larger number on top, the smaller number below:

    100x  =   173.3333....

      10x   =   17.33333...

Subtract:

      90x   =   156

Divide by 90:

         x   =   156/90  =  26/15
