You want to multiply together the number of possible choices for each digit in the code.

0-9 is ten possible numbers, since repetitions are allowed (example code 2,2,2,2) there are ten possible choices per digit in the code.

10*10*10*10 = 10,000 four digit coded possible

Answer:

B; or "a > -2"

Step-by-step explanation:

If solved by order of operations:

- divide both sides by 13

- 13 will cancel out on the left side and the when -26 will be divided by 13 the answer will be "-2"

- This leaves with the answer of "x > -2"

Hope this helps!

What is the slope of the line that passes through these points?

Natasha2012 [34]

Answer:

The slope is 6.

Step-by-step explanation:

For this, you will want to use the slope formula.

m = y2 - y1 / x2 - x1

m = 14 - 2 / 19 - 17

m = 12 / 2

m = 6

1) Factor the expression and use the fundamental identities to simplify. There is more than one correct form of the answer.

Art [367]

Answer:

Step-by-step explanation:

1) 6 tan2x − 6 tan2x sin2x

= $6tan2x(1-sin2x)\\= 6tan2x (sin^2 x + cos^2 x -2sinx cosx)\\= 6tan2x (sinx+cosx)^2\\$

2) $\frac{3}{1+cos x} +\frac{3}{1-cosx} \\=\frac{3-cosx+3+cosx}{1-cos^2 x} \\=\frac{6}{sin^2 x} \\=6 cosec^2 x$

3) $\frac{sin^2 y}{1-cosy } =\frac{1-cos^2 y}{1-cosy }\\=1+cosy$

4) x=6cos t

So cost =x/6

$sint = \frac{\sqrt{36-x^2} }{\{6 } \\$

so -3sint
