For this case we must say that it is obtained by multiplying any even number of negative numbers, that is, if a positive or negative number is obtained.
We must bear in mind that the Law of Signs states that:
For example:
Let -a, -b, -c, -d negative numbers, we have:
- A pair:
- Two pairs:
This is true for the multiplication of any pair of negative numbers.
So, the answer is: You get a positive number
Answer:
A positive number is obtained

Rounded Answer: 0
Not Rounded Answer: -0.00198019802
Step-by-step explanation:
Rounded Answer:
20/101 = 0.19801980198
Round that to 0.2
20/99 = 0.2
0.2-0.2 = 0
Not Rounded Answer:
20/101 = 0.19801980198
20/99 = 0.2
Answer: -0.00198019802
Step-by-step explanation:
sin(2x) + cos(3x)
Use double angle formula sin(2x) = 2 sin x cos x.
Use triple angle formula cos(3x) = 4 cos³x − 3 cos x.
Substitute:
2 sin x cos x + 4 cos³x − 3 cos x
Answer: 12 inches
Step-by-step explanation: In this problem, since we're asked to find the length of the median, let's use our formula for the area of a trapezoid that involves the median which is shown below.
Area = median · height
We know that the area is 144 and the height is 9 so we can set up the equation 144 = M · 12. Now to solve for <em>m</em>, we divide both sides of the equation by 12 and we find that 12 = M.
So the length of the median of the trapezoid is 12 inches.
