Select the correct answer.

a. $57,592.18

b. $57,500.68

c. $57,575.18

d. $57,609.18

e. $57,583.68

Answers

Answer:

Annual withdraw= $57,583.68

Step-by-step explanation:

Giving the following information:

Present Value (PV)= $555,000

Interest rate (i)= 0.0825

Number of periods (n)= 20

To calculate the annual withdrawals, we need to use the following formula:

Annual withdraw= (PV*i) / [1 - (1+i)^(-n)]

Annual withdraw= (555,000*0.0825) / [1 - (1.0825^-20)]

Annual withdraw= $57,583.68

Answer:

Mixed number: [tex]3\frac{15}{100}[/tex]

Improper fraction: [tex]\frac{315}{100}[/tex]

Step-by-step explanation:

A mixed number is a number that contains an integer part and a fraction part.

An improper fraction is a fraction where the numerator is greater than the denominator.

[tex]3.15[/tex] can be written as [tex]\frac{315}{100}[/tex] in its fraction form. This would be an improper fraction since the numerator is greater than the denominator.

The mixed number is [tex]3\frac{15}{100}[/tex] since [tex]100[/tex] goes into [tex]315[/tex] three full times and the remainder is [tex]15[/tex].

∴The mixed number is [tex]3\frac{15}{100}[/tex] and the improper fraction is [tex]\frac{315}{100}[/tex].

The lines represented by the equations 20y−24x=−20 and 5y−6x=−5 are...

a)perpendicular
b)the same line
c)neither parallel nor perpendicular
d)parallel

Answers

Answer:

parallel i think

Step-by-step explanation:

parallel because it's a unknown error

Answer:

Choice B

Step-by-step explanation:

The best way to compare two lines is to solve for y.

The first equation:

For [tex]20y-24x=-20[/tex] the first thing we should do is add the 24x on both sides which will cancel out itself on the left side [tex]20y=24x-20[/tex]. Now all we have to do is divide the 20 on both sides to leave us with [tex]y=\frac{6}{5}-1[/tex].

The second equation:

For [tex]5y-6x=-5[/tex] the first thing we should do is add the 6x on both side which will cancel itself on the left side [tex]5y=6x-5[/tex]. Now all we have to do is divide the 5 on both sides to leave us with [tex]y=\frac{6}{5}x-1[/tex].

Now for the comparison:

They are the same exact line. If you were to graph them they would overlap each other.

Answer:

y = 5x + 10

Step-by-step explanation:

using the formula y = mx + b you can easily find the answer.

where

m = the rate of change

b = constant

x = the independent variable

Since he has the initial $10.00 added to the account, we know that is the constant since he won’t be adding that anymore.

Since he will be adding $5.00 to the account every month we know that this is the rate of change.

the variable x will change depending on the number of months passed.

Therefore we can create the equation:

y = 5x + 10
