Rose plans to go for vacation to europe in 6 years from now. she estimates that she will need $24,388 for the trip. how much does she need to place in a saving account today that earns 5.13% per year (compounded annually) to accumulate this amount? all the work has to be shown! round the answer to two decimal places.

Answers

Let $P = the amount that Rose placed into the savings account.
The annual compounding rate is  r = 5.13% = 0.0513.
The duration is n = 6 years.
The target amount is A = $24,388.

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

The value of the account after 6 years is
[tex]A=P(1+ \frac{0.0513}{12} )^{12\times6}=P(1.00428^{72})=1.3595P[/tex]

Therefore,
1.3595P = 24388

In what instance would you use the upside down U when doing interval notation

Answers

The U and inverted U symbols, ∪ and ∩, are mathematical symbols used to denote union or intersection, respectively. For example, when a rational algebraic equation is graphed, there may be some points where the equation is undefined. Visually, we see it as breaks or discontinuities. We use the ∪ symbol to express union. For example, {-∞,2)∪(4,+∞). That means that the graph passes at all x values except x=3.

The ∩ symbol is used for intersection of two lines, for instance. When equation A and equation B are graphed, they can intersect at points (x,y). It is therefore expressed as: A∩B = (x,y).

There are three types of fraction: proper fraction, improper fraction and mixed fraction. 19/7 is an example of an improper fraction wherein the numerator is greater than the denominator. 1 4/7 is an example of a mixed fraction which contains a whole number and a proper fraction. To get the ratio, you simply divide the two fractions. But first, let's simplify the mixed fraction into an improper fraction.

The equation would be: denominator*whole number + numerator = new numerator of the improper fraction. The denominator remains the same. Thus,
1 4/7 = [(7*1)+4]/7 = 11/7 --> this is the equivalent improper fraction.

Next, you divide 11/7 by 19/7. You do this by taking the reciprocal  of the divisor and multiplying it to the dividend. This is shown as follows:

11/7 * 7/19 = 11/19

Brainliest answer please :)
So the question asks to combine like terms. This means it wants you to add the terms that are the same. For example, if you have 2n and 3n, and a question asks you to combine like terms, you would add them together and you would have 5n. In this equation, we see the terms n, and we see the numbers. So we need to simplify so that the equation has only one term with n, and only one term with numbers. So I will split it into two parts: (8n - n) + (13 + 5). Now you can solve this and you are left with 7n + 18. Therefore your answer is 7n + 18. Hope this helps. :D Feel free to ask questions about my explanation or ask any other questions.

An amount of $3000 is deposited for one year at an interest rate of 5.5% per annum. How much interest will be earned?

Answers

Answer:

$165

Step-by-step explanation:

In 1 years, you will have $165.00 of simple interest.

Calculations: The Final Investment Value, using the simple interest formula: A = P(1 + rt) where P is the Principal amount of money to be invested at an Interest Rate R% per period for t Number of Time Periods.  Where r is in decimal form; r=R/100; r and t are in the same units of time.

The accrued amount of an investment is the original principal P plus the accumulated simple interest, I = Prt, therefore we have:

A = P + I = P + (Prt), and finally A = P(1 + rt)

Calculate Total Amount Accrued (Principal + Interest), solve for A

A = P(1 + rt)

Calculate Principal Amount, solve for P

P = A / (1 + rt)

Calculate rate of interest in decimal, solve for r

r = (1/t)(A/P - 1)

Calculate rate of interest in percent

R = r * 100

Calculate time, solve for t

t = (1/r)(A/P - 1)

Final answer:

The simple interest earned on a $3000 deposit at a 5.5% annual interest rate for one year is $165. This is found using the simple interest formula: Interest = Principal x Rate x Time.

Explanation:

To calculate the amount of simple interest earned on a $3000 deposit at an interest rate of 5.5% per annum for one year, we use the simple interest formula: Interest = Principal  x Rate  x Time.

In this case:

Principal (P) is $3000,

Rate (R) is 5.5% per annum, or 0.055 when expressed as a decimal,

Time (T) is 1 year.

So, the interest earned can be calculated as follows:

Interest = $3000  x 0.055 x 1

Interest = $165

Therefore, the amount of simple interest earned on the $3000 deposit after one year is $165.

At the pie eating contest, Max ate 2⁄5 of a pie and Jen ate 6⁄8 of a pie. How many pies did they eat all together?

Answers

Final answer:

Max and Jen ate a total of 1 3/20 pies together.

Explanation:

To find out how many pies Max and Jen ate all together, we need to add the fractions of the pies that each of them ate.



Max ate 2/5 of a pie and Jen ate 6/8 of a pie. To add these fractions, we need to find a common denominator. The common denominator of 5 and 8 is 40.



Multiplying the numerator and denominator of 2/5 by 8, we get 16/40. Multiplying the numerator and denominator of 6/8 by 5, we get 30/40.



Now we can add the fractions: 16/40 + 30/40 = 46/40.



Since 46/40 is an improper fraction, we can simplify it to a mixed number by dividing the numerator by the denominator. 46 divided by 40 is 1 with a remainder of 6, so the mixed number is 1 6/40.



However, we can simplify the fractional part of the mixed number further. Both 6 and 40 are divisible by 2, so we can divide both the numerator and denominator by 2: 6 divided by 2 is 3, and 40 divided by 2 is 20. Therefore, the simplified mixed number is 1 3/20.



Therefore, Max and Jen ate a total of 1 3/20 pies together.

Final answer:

Max ate 2/5 of a pie and Jen ate 6/8 of a pie. The total is 1 and 6/40 pies.

Explanation:

To find out how many pies Max and Jen ate all together, we need to add the fractions of pies they each ate. Max ate 2/5 of a pie and Jen ate 6/8 of a pie. To add these fractions, we need to have a common denominator.

To find the common denominator, we can multiply the denominators together. In this case, the common denominator would be 5 * 8 = 40.

Now, we can convert both fractions to have a denominator of 40.

Max's fraction becomes 16/40 and Jen's fraction becomes 30/40.

Finally, we add the two fractions together:

16/40 + 30/40 = 46/40.

So, Max and Jen ate a total of 46/40 or 1 and 6/40 pies all together.

On a baseball field, the pitcher’s mound is 60.5 feet from home plate. During practice, a batter hits a ball 195 feet at an angle of 32° to the right of the pitcher’s mound. An outfielder catches the ball and throws it to the pitcher. Approximately how far does the outfielder throw the ball?

Answers

Final answer:

The outfielder throws the ball approximately 168 ft to the pitcher.

Explanation:

The outfielder throws the ball to the pitcher at an angle of 32° to the right of the pitcher's mound. To find the distance the outfielder throws the ball, we need to break down the component of the throw in the direction perpendicular to the path of the ball. This can be done by finding the horizontal component of the throw.

To find the horizontal component, we can use the equation:

horizontal component of throw = distance * cos(angle)

Substituting the given values, we have:

horizontal component of throw = 195 ft * cos(32°)

Calculating this, we find that the horizontal component of the throw is approximately 168 ft.

Find an equation of the circle whose diameter has endpoints ( −1,−4) and (3,2) .

Answers

The equation of a circle is:

(x-h)^2+(y-k)^2=r^2, where (h,k) is the center and r is the radius

So the first thing we can do is to find the center of the circle, which will be at the midpoint of the two endpoints of the diameter.  The midpoint is simply the average of the coordinates of the endpoints.

mp=((-1+3)/2, (-4+2)/2)

mp=(1, -1), and this midpoint is the center of the circle our (h,k) for the circle equation.

Now we must find the length of the diameter so that we can know what our radius is.  The distance between any two points is:

d^2=(x2-x1)^2+(y2-y1)^2 so

d^2=(-1-3)^2+(-4-2)^2

d^2=4^2+6^2

d^2=16+36

d^2=52

Note that this distance squared is our diameter squared.

Since d=2r

d^2=4r^2

r^2=d^2/4, we showed that d^2=52 so

r^2=52/4 

r^2=13  (r=√13, but we need r^2 for our equation anyway)

So now we can fill out our circle equation because we know the center is at (1,-1) are r^2=13

(x-1)^2+(y+1)^2=13

Final answer:

The equation of the circle with diameter endpoints (-1,-4) and (3,2) is (x - 1)^2 + (y + 1)^2 = 13, found by calculating the center at (1, -1) and the radius as sqrt(52)/2.

Explanation:

To find an equation of the circle whose diameter has endpoints at (-1,-4) and (3,2), we need to determine the center and radius of the circle. The center of a circle is the midpoint of the diameter, and the radius is half the length of the diameter.

First, we calculate the midpoint (which will be the center of the circle) using the formula: (x1 + x2)/2, (y1 + y2)/2. For the given points (-1,-4) and (3,2), the midpoint is ((-1 + 3)/2, (-4 + 2)/2), which simplifies to (1, -1). So, the center of the circle is (1, -1).

To find the radius, we use the distance formula: sqrt((x2 - x1)^2 + (y2 - y1)^2). The distance between the two points is sqrt((3 - (-1))^2 + (2 - (-4))^2), which simplifies to sqrt(4^2 + 6^2) = sqrt(16 + 36) = sqrt(52). The radius is half of the diameter, so r = sqrt(52)/2.

The standard form of a circle's equation is (x - h)^2 + (y - k)^2 = r^2, where (h, k) is the center of the circle and r is the radius. Substituting the values we found, we get (x - 1)^2 + (y + 1)^2 = (sqrt(52)/2)^2, which simplifies to (x - 1)^2 + (y + 1)^2 = 13. This is the equation of the circle.

Combinations- how to show that 10C2=10C8

Answers

The most effective way to show that 10C2 = 10C8 is to solve for the values of each combination. To solve for the values, we have to make use of the combination formula:

nCr = n! / r! (n – r)!

where n is the total sample size and r is the selected sample size

 

Calculating the value of 10C2:

10C2 = 10! / [2! (10 – 2)!]

10C2 = 10! / (2! * 8!)

10C2 = 45

 

Calculating the value of 10C8:

10C8 = 10! / [8! (10 – 8)!]

10C8 = 10! / (8! * 2!)

10C8 = 45

 

Therefore,

10C2 = 10C8
