A 270-degree clockwise rotation about the origin is equivalent to a 90-degree counterclockwise rotation about the origin. It is also equivalent to itself (270 clockwise = 270 clockwise)

The two correct answers are B and D.

I hope this helps =)

Increase 14187.13 by 4.5%

Ksivusya [100]

If you increase a number by 4.5%, then you're adding 4.5% of that number to 100% of that number. So essentially you just multiply 14187.13 by 104.5%, or 1.045 to find the answer, which is 14,825.55.

What is the radius of convergence of the maclaurin series (2x)/(1+x^2)?

kramer

To solve this problem you must apply the proccedure shown below:
1. You have to find the radius of convergence of the following Maclaurin series:
 $(2x)/(1+ x^{2} )
$
2. Let's take the denominator and find the roots:
$1+ x^{2} =0$
$x^{2} =-1 \\ x= \sqrt{-1} \\ x1=i \\ x2=-i$
3. The roots are $x1=i \\ x2=-i$ and the distance from the origin is $1$ .
Therefore, the answer is: $1$
