A couple deposits $21,000 $ 21,000 into an account earning 5% 5 % annual interest for 30 30 years. Calculate the future value of the investment if the interest is compounded daily. Round your answer to the nearest cent.
Answer:
$94105.81
Step-by-step explanation:
[tex]21000( ({1 + .0512675})^{30} - 1) \\ = 73105.81 \\ 73105.81 + 21000 = 94105.81[/tex]
Future value of the investment if the interest is compounded daily is $94,105.80.
What is Compound Interest?Compound interest is defined as the amount of interest which has been calculated on the principal amount as well as the amount accumulated over the previous period is also included.
Given that,
Principal amount, P = $21,000
Rate of interest, r = 5% = 5/100 = 0.05
Time, t = 30 years
The final amount in a compound interest is,
A = P (1 + r/n)^(nt), where n is the number of times compounding is done in a year.
Here, n = 365
A = 21000 (1 + 0.05/365)^(365 × 30)
= 94,105.802
≈ 94,105.80
Hence the final amount is $94,105.80.

In an experiment, a fair four-sided die (its faces are labeled 0, 1, 2, 3) is thrown once. The outcome of the throw determines how many times a fair coin is to be flipped: if N is the number that results from throwing the die, we flip the coin N times. Let K be the total number of heads resulting from the coin flips.

Evaluating an algebraic expression is the process of determining the value of an expression when a specified integer is used to replace a variable.
Explain about the expression?Mathematical expressions consist of at least two numbers or variables, at least one arithmetic operation, and a statement. It's possible to multiply, divide, add, or subtract with this mathematical operation. An expression's structure is as follows: Expression: (Math Operator, Number/Variable, Math Operator)
An expression in mathematics is made up of numbers, variables, and functions (such as addition, subtraction, multiplication or division etc.) You can think of expressions as being comparable to phrases. A phrase in language may contain an action on its own, but it does not constitute a whole sentence.
In mathematics, an expression that incorporates variables, constants, and algebraic operations is known as an algebraic expression (addition, subtraction, etc.). Terms comprise expressions.

Answer:
f^-1(x) = ∛((x +5)/2)
Step-by-step explanation:
Continue to solve for y.

Joe bought a box of laundry detergent that contains 195 scoops each load of laundry uses 2 1/2 scoops the box of detergent was $24.96 how much is he paying for each load that was wash
Answer:
a) Number of laundry he can do with this box = 78 laundries.
b) Price he paying for each load = 0.256 $
Step-by-step explanation:
Total scoop contained in detergent box = 195 scoops.
Scoops used by each load of laundry = 2 1/2 = 2 * 2 + 1/2 = 5/2 scoops = 2.5 scoops
Number of laundry he can do with this box = 195/2.5 = 78 laundries.
Price of detergent box = 19.99 $
Price he paying for each load = Total price/ Number of loads
= 19.99/78
= 0.256 $

In a newspaper, it was reported that the number of yearly robberies in Springfield in
2011 was 75, and then went down by 4% in 2012. How many robberies were there in
Springfield in 2012?
72 is answer
as it got down by 4% every year
in 2011 it was 75 means in the next year it will be 75-(75*4/100) that is equal to 72
The robbery rate in year 2012 was 72.
What is percentage?A percentage is a number or ratio that can be expressed as a fraction of 100.
Given that in a city that robbery rate was 75 in 2011 was 75, and then went down by 4% in 2012.
We need to find the robbery rate of the city in 2012.
So, here went down means it decreased by 4%,
That mean, now the robbery rate will be (100-4) = 96% of 75.
Therefore, the robbery rate in year 2012 was =
0.96 x 75 = 72
Hence the robbery rate in year 2012 was 72.
