If you invested $10000 in a stock with 5% compounded monthly you will have $16470 in 10 years.

Compound interest is simply interest that is earned over prior interest. You receive interest on the initial principal as well as the interest that builds up over time when you open a savings account that pays compound interest.

When you deposit funds into a savings account or other type of account, you will earn interest on the amount you deposited. For instance, after a year, if you deposited $1,000 in an account with 1% annual interest, you would have received $10 in interest.

Compound interest formula is

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

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,

P = $10000

r = 5%

n = 12

t = 10

A = to find

Lets solve,

[tex]$\text A = 10000(1 + \frac{0.05}{12})^{12\times 10}[/tex]

The roots of the quadratic function f(b) = b² - 75 are Ob=5√3 and Ob=-5√3.

A quadratic function is a polynomial function of degree two, which means it is a function that can be expressed as an equation with the second-degree degree of the highest exponent of the unknown variable. It is typically expressed as ax^2 + bx + c, where a, b and c are constants, and x is an unknown variable. Quadratic functions can be used to model many real-world situations, such as the height of a projectile in motion or the area of a circle.

The Quadratic Formula can be used to solve for the roots of a quadratic function. The Quadratic Formula states that for a quadratic equation of the form ax² + bx + c = 0, the two roots are given by x = [-b ± √(b² - 4ac)]/2a.

In this case, a = 1, b = 0, and c = -75. Therefore, the two roots are given by x = [-0 ± √(0² - 4(1)(-75)]/2(1). This simplifies to x = [0 ± √(75)]/2, or x = ±5√3/2. The two roots are thus Ob=5√3 and Ob=-5√3.

Answer:

100%

Step-by-step explanation:

The mark-up percentage is the amount by which the cost price of a product is increased to arrive at the selling price. To calculate the mark-up percentage, you can use the formula:

Mark-up percentage = (selling price - cost price) / cost price x 100

In this case:

Cost price = $450

Selling price = $900

Mark-up percentage = ($900 - $450) / $450 x 100 = 100%

So the specialty shop has a mark-up of 100% on each painting.

It means that the shop is charging twice as much as the price they procured the paintings.

What is average ?

An average, also known as a mean, is a measure of central tendency that represents the typical value of a set of data. To calculate the average of a set of numbers, you add them up and then divide by the number of items in the set.

Time = Distance / Speed

For the swimming segment, the distance is 0.93 miles and the speed is 2.1 mph. So the time it will take Chantel to swim the 0.93 miles is:

Time = 0.93 / 2.1 = 0.445 hours or 26.7 minutes

For the biking segment, the distance is 24.8 miles and the speed is 18.2 mph. So the time it will take Chantel to bike the 24.8 miles is:

Time = 24.8 / 18.2 = 1.367 hours or 81.02 minutes

For the running segment, the distance is 6.2 miles and the speed is 5.1 mph. So the time it will take Chantel to run the 6.2 miles is:

Time = 6.2 / 5.1 = 1.216 hours or 72.96 minutes

To get the total time, you have to add the time for each segment:

Total time = 0.445 + 1.367 + 1.216 = 2.028 hours or 122.68 minutes

So , It will take Chantel approximately 2.028 hours or 122.68 minutes to complete the triathlon.

Kallie and Jeie sold 4 regular lemonade for $1.50 amount each, and 16 strawberry lemonade for $2 each, and made a total of $45.

Regular Lemonade: 9

Strawberry Lemonade: 21

Regular Lemonade:

Price of Regular Lemonade = 1.50

Total earnings from Regular Lemonade = 9 x 1.50 = 13.50

Strawberry Lemonade:

Price of Strawberry Lemonade = 2

Total earnings from Strawberry Lemonade = 45 - 13.50 = 31.50

Number of Strawberry Lemonade sold = 31.50 / 2 = 15.75

Number of Regular Lemonade sold = 15.75 - 12 = 3.75

a) To find out the number of people that need to sign up for the profit to be at least $108 where the function y = - x7 + 24x, models profit in y,

we must equate the function to $108 and solve for x.

Thus:

x = 108/17

x = 6.35294117647

A mathematical definition of an equation is a claim that two expressions are equal when they are joined by the equals sign ("=").

A: X is the quantity of pizzas, while Y is the quantity of bags of chicken wings.

1 pizza cost x, thus 6 cost = 6 x

1 bag of chicken wings costs y dollars, thus 7 cost = 7 y.

Given: Total cost = 6x + 7y = 70

Total servings are now equal to (24)(2) for a total of 48.

One pizza includes four portions, thus 1 x 4 = 4

Servings in a bag of chicken wings are 5y.

Answer: Let "t" be the fare of the train.

The fare of the bus is "b".

We know that t + b = 4000 (the total fare of the journey)

On the return trip, the fare of the bus was hiked by half of what was paid, so b*1.5 = b + (b/2) = new fare of the bus.

The total fare of the return journey is 4800, so t + (b + (b/2)) = 4800

Now we have two equations:

t + b = 4000

t + b + (b/2) = 4800

We can substitute the first equation into the second equation:

t + b + (b/2) = 4800

t + (4000 - t) + (b/2) = 4800

t + (b/2) = 800

t = 800 - (b/2)

Now we have an equation that only involves one variable "t" (the fare of the train)

We can substitute the first equation back in:

t + b = 4000

800 - (b/2) + b = 4000

800 = (3/2)b

b = 1200

So the fare of the bus is 1200 and the fare of the train is 800
