You would like to have $20,000 to use a down payment for a home in five years by making regular, end-of-month deposits in an annuity that pays 6% interest compounded monthly. How much of the $20,000 down payment comes from interest earned? Round your answer to the nearest cent. Do NOT round until you have calculated the final answer. Do NOT include the dollar sign in the answer box below.
Using compound interest, it is found that $5,172.56 comes from interest earned
What is compound interest?The amount of money earned, in compound interest, after t years, is given by:
[tex]A(t) = P\left(1 + \frac{r}{n}\right)^{nt}[/tex]
In which:
A(t) is the amount of money after t years. P is the principal(the initial sum of money). r is the interest rate(as a decimal value). n is the number of times that interest is compounded per year. t is the time in years for which the money is invested or borrowed.In this problem:
$20,000 is required in five years, hence t = 5, A(5) = 20000.Interest rate of 6%, hence r = 0.06.Monthly compounding, hence n = 12.First, we have to find the principal needed, hence:
[tex]A(t) = P\left(1 + \frac{r}{n}\right)^{nt}[/tex]
[tex]20000 = P\left(1 + \frac{0.06}{12}\right)^{12(5)}[/tex]
[tex]P = \frac{20000}{(1.005)^{60}}[/tex]
[tex]P = 14827.44[/tex]
Hence:
$14,827.44 comes from the principal.$5,172.56 comes from interest earned, as $20,000 - $14,827.44 = $5,172.56.To learn more about compound interest, you can take a look at https://brainly.com/question/25781328

Step-by-step explanation:
you simply have to mark the points in which the x and y coordinates are given take for example "1,4" it took him 4 minutes to read 1 page right? the one is marked as X and the 4 is marked as Y so put a point in which the 1 at X and the 4 at Y meet in the coordinates system. Do so with every coordinates and then draw a line in the direction of all the points
just mark down the coordinates on the plane, like this.

Answer: 325
Step-by-step explanation:
All your doing is multiplying
Answer:
The answer is 325
Step-by-step explanation:
the problem directly tells me that c(x)= 50x is how many words i can type in x minutes. then proceeds to ask me how many words i can type in 6.5 minutes.
in this case, x=6.5.
substitute and solve!
c(6.5)= 50(6.5)
c(6.5)= 325
according to this function, i can type 325 words in 6.5 minutes.

Answer:
f(2) = 0.5(2) +3.4f(3.5) = 0.5(3.5) +3.4f(15) = 0.5(15) +3.4f(21.3) = 0.5(21.3) +3.4Step-by-step explanation:
Put the given weight where x is in the function definition. You're only asked for the expression, not its value.
f(2) = 0.5(2) +3.4f(3.5) = 0.5(3.5) +3.4f(15) = 0.5(15) +3.4f(21.3) = 0.5(21.3) +3.4A shoe store has 23 pairs off white tennis shoes out of 90 pairs of shoes. Estimate the percent of white tennis shoes.
Answer:
percent=25.56%
Step-by-step explanation:
Percentages
To know the percentage of having n elements out of a total of m elements, we calculate the ratio n/m and express the result as a percentage.
The shoe store has 23 pairs of white shoes out of 90 total pairs of shoes. The percent of white tennis shoes is calculated as follows:
[tex]\displaystyle percent= \frac{23}{90}*100\%[/tex]
Operating:
percent=25.56%

Get 2 points off each line
(x1, y1)
(x2, y2)
And sub them into the formula.
The y intercept is where the line cuts the y axis (the vertical line)
From what I can make out the y intercept for the first part in question 12 is (0,-2) and for the third part is (0,0) but I can't see the second one.
It might help if you took a clearer photograph I'm so sorry but I can't really see it.

Answer:
3600
Step-by-step explanation:
lcm stands for "lowest common multiple"
the lcm is 3600 when done with the prime factorization process
Answer:
3600
Step-by-step explanation:
Express each number as a product of its prime factors, that is
36 = 2² × 3²
75 = 3 × 5²
80 = [tex]2^{4}[/tex] + 5
Now multiply each factor the greatest number of times it occurs in each of the 3 numbers.
2 → 4 times (that is [tex]2^{4}[/tex] )
3 → twice (3² )
5 → twice (5² )
Thus
LCM = [tex]2^{4}[/tex] × 3² × 5² = 16 × 9 × 25 = 3600
