If you want to enter something like 

$$1\frac{2}{3}$$

then just type (1 + 2/3)

.

The firstfour terms of (1 + m)⁶ are 1 + 6m + 6*5/2*m² + 6*5*4/(3*2)*m³

So if m = x/3 

a = 6/3 = 2

b = 6*5/2*(1/3²) = 30/18 = 5/3

c = 6*5*4/(3*2)*(1/3³) = 20/27

You cant there are only decimals.

Use the mod function on the calculator here

$${\mathtt{3\,997}} \,{mod}\, {\mathtt{5}} = {\mathtt{2}}$$

2 is the remainder when 3997 is divided by 5

.

I think you must mean 855 degrees (not 885 degrees).  Most calculators won't display results as fractions, but you can do this by continuing to subtract 360 degrees from this until you get to 135 degrees (855 - 360 -360 = 135).  sec, like cos,  is negative here (sec = 1/cos).

Imagine a line on a graph from the origin (0, 0) to the point (-1, 1).  This is at angle of 135 degrees to the positive x-axis (45 degrees to the negative x-axis).  

The length of the diagonal of this line is √(1^2 -(-1)^2) = √2

Then sec(135) = √2/(-1) = -√2

.

Put the decimal point after the first non-zero digit, then multiply by ten to the power of however many decimal places are needed to complete the number as in your example.  If the number is smaller than 10 then you will need a negative exponent on the ten.  For example:  0.0108 = 1.08*10^(-2)

Find three consecutive even numbers that sum to 66

$$\underbrace{(a_2-2)}_{=a_1}+a_2+\underbrace{(a_2+2)}_{=a_3}=66\\\\
3a_2=66 \quad | \quad :3\\
a_2=22\\
a_1=a_2-2=22-2=20 \\
a_3 = a_2+2=22+2=24\\\\
20 + 22 + 24 = 66$$

$$\frac{1-x^2}{x^{3/4}}=\frac{1}{x^{3/4}}-\frac{x^2}{x^{3/4}}=x^{-\frac{3}{4}}-x^{2-3/4}=x^{-\frac{3}{4}}-x^\frac{5}{4}$$

Suppose this was real, and your parents get super mad, then what would you do?

(h + 5)^2 = h^2 + 2*5*h + 5^2 = h^2 + 10h + 25

Suppose he had N hats on Monday.

On Tuesday he had N + 8 hats.

On Wednesday he had (N + 8)/2 hats.

On Thursday (N + 8)/2 = 20

Multiply both sides by 2

N + 8 = 40

Subtract 8 from both sides

N = 32  

This is how many hats he had on Monday.

.

You could just write this as 

$$x^{\frac{3}{4}}$$

.

To get slope intercept form isolate the y, so:

3x + 5y = -5

Subtract 3x from both sides:

5y = -3x - 5

Divide all terms by 5:

y = -(3/5)x - 1

This is now in slope intercept form, where the slope is -(3/5) and the y intercept is -1.

Call a doctor.  That's enough sugar to give a water buffalo a heart attack

20 

22

24

it would be 21.5172414

you would take 2 and divide it -16 by it and then theres "x" and then you would put the number that you got and put it in for "x" and see if its right

You had trouble adding the numbers. Add it like you add normaly!!!                                                                                  

Easy as that.

why are you asking that on a math wesite lol and just go to them and say that your sorry for whatever happened and ask if yall can be friends again

its 19 ad 21
