Answer:

0

Step-by-step explanation:

The cotangent function is defined as cot x = adj / opp.

The terminal side of 270 degrees is the lower half of the y-axis.  The adj side is zero (0) and the opp side is -1;

Therefore, cot (-270 degrees) = adj / opp = 0/(-1) = 0

The area of a rectangle with width x and length 6x and 6x^2. What does the coefficient 6 mean in terms of the problem?
sveta [45]

Answer:

The coefficient 6 in 6x means 6(x) or 6 multiplied by x 6 times.

Step-by-step explanation:

X could be anything, it is only holding the place of a number. The coefficient 6  before the x is a number being multiplied by the unknown variable, x. For example if x = 2 the expression would turn into 6(2) which equals 12.

Hope this helps! If you have any other questions please don't hesitate to ask me or your teacher so you can be sure to master the subject. :)

Charlie colors 45% of the total shapes on her paper. she colors 18 shapes .
love history [14]
Hey there!

Here is your answer:

<u>The proper answer to this question is "40".</u>

Reason:

<u>40/x=100/45</u>
<u>(40/x)*x=(100/45)*x       - we multiply both sides of the equation by x</u>
<u>40=2.22222222222*x       - we divide both sides of the equation by (2.22222222222) to get x</u>
<u>40/2.22222222222=x </u>
<u>18=x </u>
<u>x=18</u>

<span>45% of 40=18

If you need anymore help feel free to ask me!

Hope this helps!
