Answer: 40
Step-by-step explanation:
The expressions is undefined in the set of the real numbers.
Question 4
The magnitude;
Using Pythagoras theorem,
(-200)² + (-530)² = 320900
Length = √320900
= 566.5 mi
To get the angle
Tan θ = opposite/adjacent
= 200/530
= 0.3774
θ = tan^-1 (0.3774)
= 20.67
≈ 21°
The direction from the Cartesian plane is south of west.
Therefore, the magnitude and the direction will be;
About 566.5 mi, 21° south of west
Question 5.
To get the resultant of two vectors we just add the two vectors given.
This involves adding the corresponding values.
Thus, for <-6,5> and <6,-5>
Resultant vector = <(-6+6),(5+-5>
= <0,0>
Answer:
$50
$30.88
I will invest in simple interest as the interest there is more.
Step-by-step explanation:
If I invested $500 at 5% simple interest for 2 years, then the interest that I will get will be given by the formula
, where P is the invested principal, r is the APR and t is the time in years.
So, in our case, 
dollars. (Answer)
Now, if I invest $500 at 3% compound interest compounded monthly for 2 years.
Now, using the formula of compound interest we have
, where r is the APR and n is the number of times in a year the principal is compounded.
In our case, 
dollars. (Answer)
Therefore, I will invest in simple interest as the interest there is more. (Answer)
17. The letter is J
The letter appears 3 times
18. Lefthanded students = 4 students
<h3>How to determine the factors</h3>
17. We have that 1/4 of the months of the year start with the same letter
It is important to note that:
January, June and July all start with the same letter
The letter is J
The letter appears 3 times
18. Total number of students = 24
5/ 6 are right handed
Right handed students = 24 × 5/ 6 = 4 × 5 = 20 students
Lefthanded students = 24 - righthanded students
Lefthanded students = 24 - 20
Lefthanded students = 4 students
Thus, we can see that the letter that appear in 3 months of the year is J
