Dante will have $5872.50 after 4 years, when compounded $5,000 into an account with an annual interest rate of 3.5%.

Simply put, interest is the cost of borrowing money, whether it be through a student loan, a mortgage, or a credit card. When you borrow money, you typically have to pay it back along with interest that is calculated as a percentage of the loan amount. There are a few exceptions, such as when you pay off your credit card balance in full each month or when you have a promotional 0% interest rate.

You might be eligible for lower interest rates if prospective creditors and lenders view your track record of responsible credit behaviour and view you as a low-risk borrower.

The compound interest formula is given by

[tex]$A = P(1 + \frac{r}{n})^{nt}[/tex]

[tex]$A = P(1 + \frac{r}{n})^{nt}[/tex]

Where,

A = final amount

P = initial principal balance

r = interest rate

n = number of times interest applied per time period

t = number of time periods elapsed

Here,

A = to find

Answer:

(1,4)

Step-by-step explanation:

The average rate of change for the interval from x = 5 to x = 6 can be calculated by taking the derivative of the quadratic function and evaluating it at the midpoint of the interval (x = 5.5).

Given that the vertex of the function is at (1, 0), the equation of the quadratic function is in the form of:

f(x) = a(x-1)^2 +0

The derivative of the function is:

f'(x) = 2ax - 2a

We know that the vertex of the function is at (1,0), which means that the value of a is 0.

So the derivative of the function is 0.

Therefore the average rate of change for the interval from x = 5 to x = 6 is 0.

Answer: The study indicated that residents of Springtown wasted 7,622 gallons of water this year, which is 85% more than they wasted last year. To find out how many gallons of water the city's residents wasted last year, we need to find out what 85% of 7,622 gallons is and then subtract that amount from the total amount wasted this year.

85% of 7,622 gallons is (85/100) * 7,622 = 6,465.7 gallons

So, if residents of Springtown wasted 7,622 gallons of water this year, which is 85% more than they wasted last year, then they wasted 7,622 - 6,465.7 = 1,156.3 gallons of water last year.

Step-by-step explanation:

Answer:

x = 4120 gallons wasted last year

Step-by-step explanation:

Let x be the amount of water wasted by the residents of Springtown "last year."

They wasted 85% more this year.  This would mean that x*(1+ 0.85) = 7622 gallons.  [The "(1+0.85)" represents the decimal equivalent to "85% more."

x*(1+ 0.85) = 7622

1.85x = 7622

x = 4120 gallons wasted last year

Check:

Is 7622 85% more than 4120?

(7622-4120)=3502

(3502/42=4120) = 0.85  YES

Answer:

The effective tax rate for a taxable income of $145,690 would be 24.39%.

Step-by-step explanation:

To find the effective tax rate, you need to calculate the total amount of tax paid on the taxable income, and then divide that amount by the taxable income, and multiply by 100 to express it as a percentage.

We can see from the marginal tax rate chart that for a taxable income of $145,690, the marginal tax rate is 24%. This means that the last dollar earned falls in the 24% tax bracket.

We can calculate this in the following steps:

Determine the taxable income in each tax bracket:

$10,276 - $41,175: $41,175 - $10,276 = $30,899

$41,176 - $89,075: $89,075 - $41,176 = $47,899

$89,076 - $170,050: $145,690 - $89,076 = $56,614

Calculate the taxes owed in each tax bracket:

$10,276 - $41,175: $30,899 x 12% = $3,707.88

$41,176 - $89,075: $47,899 x 22% = $10,526.78

$89,076 - $170,050: $56,614 x 24% = $13,547.36

Add up the taxes owed in each bracket to find the total taxes: $3,707.88 + $10,526.78 + $13,547.36 = $27,782.02

Divide the total taxes by the taxable income and multiply by 100 to find the effective tax rate: $27,782.02 / $145,690 x 100 = 19.02%

The effective tax rate for a taxable income of $145,690 would be 19.02%.

4 + 46 = 5c - 46 + 46

50 = 5c

4 = 1(6) + c

c = -2

The slope of a line is a measure of how steep the line is. It is the ratio of the change in the y-coordinate (rise) to the change in the x-coordinate (run) between two points on the line. The slope is also commonly referred as the "gradient" of a line. A line with a positive slope goes up from left to right, a line with a negative slope goes down from left to right, and a line with a slope of 0 is a horizontal line.

The formula to calculate the slope (m) with given two points (x1, y1) and (x2, y2) is:

m = (y2 - y1) / (x2 - x1)

The equation of a line in slope-intercept form is y = mx + b, where m is the slope of the line and b is the y-intercept (the point where the line crosses the y-axis). Since the line has a slope of 1 and passes through the point (10, c), we know that the y-intercept is c.

An example of a continuous probability distribution is the normal distribution, in which the majority of data points cluster near the middle of the range and the remaining ones decrease symmetrically toward one of the extremes.

Maximum Value=121.9

Number of classes=5 (say)

Range=121.1-121.9=0.8

Minimum Value= 121.1

width of each class= 0.8 / 5 = 0.16 = 0.2 (approx)

Therefore, we must create classes so that the first class has the minimum value and the last class contains the highest value. The class interval will therefore be 121.1 - 121.3, 121.3 - 121.5, and so on with a class width of 0.2 volt.
