Answer:
1
Step-by-step explanation:
2%= 0.2
0.2*5= 1
When finding Percent of whole multiply.
Answer:
22%
Step-by-step explanation:
So First we subtract 90 and 70 = 20
Then we divide 20 by 90 = which gives us approximately 0.22 then we turn that into a percent by moving the decimal point 2x to the right.
So In conclusion, the percent decrease is 22%
Remember the formula is:
amount of change ÷ by the original amount

By De Moivre's formula, the <em>cubic</em> roots of the <em>complex</em> number are 3 + i 4, - 4.96 + i 0.60 and 1.96 - i 4.60.
<h3>How to find the cube root of a complex number</h3>
Herein we have a <em>complex</em> number in <em>rectangular</em> form, from which we need its magnitude (r) and direction (θ) and the De Moivre's formula as well. The <em>root</em> formula is introduced below:
, for k ∈ {0, 1, ..., n - 1} (1)
Where n is the grade of the complex root.
The magnitude and direction of the <em>complex</em> number are 125 and 0.886π radians, respectively. Thus, by the De Moivre's formula we obtain the following three solutions:
k = 0
z₁ = 2.997 + i 4.002
k = 1
z₂ = - 4.964 + i 0.595
k = 2
z₃ = 1.967 - i 4.597
By De Moivre's formula, the <em>cubic</em> roots of the <em>complex</em> number are 3 + i 4, - 4.96 + i 0.60 and 1.96 - i 4.60.

Answer: he would have $13134 at the end of 10 years
Step-by-step explanation:
The formula for continuously compounded interest is
A = P x e (r x t)
Where
A represents the future value of the investment after t years.
P represents the present value or initial amount invested
r represents the interest rate
t represents the time in years for which the investment was made.
e is the mathematical constant approximated as 2.7183.
From the information given,
P = $9000
r = 3.79% = 3.78/100 = 0.0378
t = 10 years
Therefore,
A = 9000 x 2.7183^(0.0378 x 10)
A = 9000 x 2.7183^(0.378)
A = $13134 to the nearest dollar
