Answer:
The Answer to your problem is 3 √ 2
Step-by-step explanation:
Step 1. Find 0 ( helps to plot z on complex plane)
z is in quadrant 4
0 is between -/z and 0
Step 2. Find modulus |z|
|z|= check mark 3 to the power of 2 + (-3) power of 2 = check mark, 9+9 = check mark 18 =check mark 9.
Step 3. Write out z in polar form
z = 3 check mark 2.

Answer:
The correct answer is a. $2275.28; b. 17.04 years
Step-by-step explanation:
Principal to be invested is $2000
Interest rate (r) per year is 6.5 quarterly.
Interest is calculated compoundly.
a. Time (t) for the investment is given to be 2 years.
Amount after two years is = Principal × where the value of n is 4.
⇒ A = 2000 ×
⇒ A = $2275.28.
b. Now the value of A is given to be triple the principal = $ (3 × 2000).
Therefore we need to find the value of t.
⇒ 3 × 2000 = 2000 ×
⇒ ㏑ 3 = 4t × ㏑ ( 1.01625)
⇒ t = 17.04
Therefore it would take 17.04 years for the principal to triple.
