You don't graph it you just answer it.

theta = pi/6  and  5pi/6

It is inverse tan

[2nd]  [atan]     your number  

If you want to put it inot the calculator, it is

10^23

-9 + -3

=-12

that is the answer

Negative 12

-9+-3=-12

Because they are both negatives and The negative -9 adds negative -3 more so -12 

1000 / 10 = 100

3x2 - y3 - y3 - z if x = 3, y = -2, and z = -5.

$$\\3x^2 - y^3 - y^3 - z\\\\
=3*3^2 - (-2)^3 - (-2)^3 - (-5)\\\\
=3*9 - -8 - -8 - (-5)\\\\
=27+8+8+5\\\\
=48$$

-------------------------------------------------

check

3*3^2 - (-2)^3 - (-2)^3 - -5 

$${\mathtt{3}}{\mathtt{\,\times\,}}{{\mathtt{3}}}^{{\mathtt{2}}}{\mathtt{\,-\,}}{\left(-{\mathtt{2}}\right)}^{{\mathtt{3}}}{\mathtt{\,-\,}}{\left(-{\mathtt{2}}\right)}^{{\mathtt{3}}}{\mathtt{\,\small\textbf+\,}}{\mathtt{5}} = {\mathtt{48}}$$      

3ax = 1/5

divide by 3a on both sides

x = 1/15a

1 googol is 1.0 × 10¹⁰⁰

10.3 , 10.9 , 10.6 , 10.1 , 10.5

Add them all together

52.4

Now divide by the number of numbers (5)

10.48

1/3 ÷ 9

Use the recipricle and multiply

1/3 x 9/1

Multiply

9/3 

Simplify

Thanks Guys! 

The value of sin(x) is pinned between -1 and + 1. It can be -1 at 270° ± k·360° (where k is any integer).

It can be +1 at 90° ± k·360° (where k is any integer).

For all other values of x, sin(x) must be between these two values.

If you think back to a right triangle, sin is defined to be the length of the opposite side divided by length of the hypotenuse. In a right triangle, the opposite side cannot be longer than the hypotenuse, thus the value of sin can never by greater than 1.

2/3 (9-m)= 2m+7 

multiply both sides by 3 to get rid of the fraction

2(9-m)=2m+7

18-2m=2m+7

add 2m to both sides

18=4m+7

subtract 7 from both sides

11=4m

11/4=m

$$m=2\frac{3}{4}$$

Thanks for the help!

Let me explain in detail, so you can apply this to other problems of the same kind.

When the variable is the same, then you can add the coefficients (numbers before the variables) like normal.

Since the variable (x) in -3x + 9x is the same you can just add the coefficents together: -3 + 9.

When you add a negative number to a positive number, it's the same thing as subtracting that negative.

So: -3 + 9 = 9 -3. Since 9 - 3 = 6, our answer is 6x.

So we have: -2 * 1/3. To multiply fractions, multiply the numerator and denominator. -2 = -2/1. So it's now: -2/1 * 1/3. -2 * 1 = -2; 1 * 3 = 3. Therefore our answer is: -2/3.

Use the site calculator:

$${\mathtt{200\,000\,001}}{\mathtt{\,\times\,}}{\mathtt{4}} = {\mathtt{800\,000\,004}}$$

Yes but can you do them on the calculator OR do you have to do them by hand?

 e^2 = e * e.

9 plus -3 is equal to 6

(9-3)

then add the variable onto the six.

(6 times x)...(6x)

Why is there slavery going on in a math problem? This math problem goes against the 13th amendment!
