Answer:

False

Step-by-step explanation:

the <u>dot product</u> between two vectors A and B is:

A·B=AB $cos\theta$

where $\theta$ is the angle between the vectors, if they are parallel, this angle is zero. so $\theta=0$

and so the dot product is:

A·B =AB $cos(0)$

and since $cos (0)=1$

the dot product is equal to

A·B=AB

The dot product of parallel vectors is NOT zero

The annual interest rate of Mike's savings account is 4.8%, and simple interest is calculated monthly. What is the periodic inte

Reptile [31]

The correct option will be: d. 0.4%

For finding the periodic interest rate , we need to divide the annual interest rate by the number of times interest calculated in a year.

Here, the simple interest is calculated monthly, that means the number of times interest calculated in a year will be 12.

Annual interest rate is 4.8%

So, the periodic interest rate = $\frac{4.8}{12}= 0.4$ %
