Using compound interest formula when the CD matures on Melissa's 14th birthday, there will be $3187.69 available.

The interest that is calculated using both the principal and the interest that has accrued during the previous period is called compound interest. It differs from simple interest in that the principal is not taken into account when determining the interest for the subsequent period with simple interest. Compound interest is commonly abbreviated C.I. in mathematics.

Use the formula for compound interest to calculate the amount of money that will be available when the CD matures -

\(A = P(1 + r/n)^(nt)\)

Where A is the amount of money available when the CD matures, P is the initial principal, r is the interest rate, n is the number of times the interest is compounded per year, and t is the time in years.

In this case, the initial principal is $2000, the interest rate is 6%, and the CD will be held for 8 years (from Melissa's 6th to 14th birthday).

It is not given how many times per year the interest is compounded, so assume it is compounded annually.

Using these values in the formula -

\(A = $2000(1 + 0.06/1)^(1*8)A = $2000(1.06)^8A = $3187.69\)

Therefore, the value is obtained as $3187.69.

The height of each bar in a histogram represents the frequency or count of the data values that fall within the range specified by that bar.

For example, if a histogram has a bar that ranges from 0-10 and the height of that bar is 5, it means that there are 5 data values that fall within the 0-10 range. Each bar in a histogram represents a different range of data values, and the height of the bar indicates how many data values fall within that range.

In other words, the height of each bar in a histogram represents the number of times that a certain range of data values occurs in the data set.

The formula for determining the nth term in a sequence of approximations to a solution of a polynomial equation is known as Newton's method or Newton-Raphson method. It is an iterative process that involves using the derivative of the polynomial to refine the approximation.


1. Start with an initial guess for the solution, denoted as x0.
2. Use the polynomial equation and its derivative to calculate the next approximation using the formula:
  x1 = x0 - (f(x0) / f'(x0))
  where f(x0) is the value of the polynomial at x0 and f'(x0) is the derivative of the polynomial evaluated at x0.
3. Repeat step 2 until the desired level of accuracy is achieved or until a maximum number of iterations is reached.

Therefore, Newton's method is an iterative approach that uses the derivative of the polynomial to refine the approximation to the solution of a polynomial equation.

(4x+5)(3x^2 + 1x -8)    Apply the distributive property twice to solve

4x ( 3x^2 + 1x -8)  

12x^3 + 4x^2 - 32x  

5(3x^2 + 1x -8)  

15x^2 + 5x - 40

12x^3 + 19x^2 -27x -40

The function g(f(x)) will be written as g(f(x)) = 12x² + 4x - 27.

A function is an assertion, concept, or principle that establishes an association between two variables. Functions may be found throughout mathematics and are essential for the development of significant links.

The functions are given below.

f(x) = 3x² + x - 8 and g(x) = 4x + 5

The function g(f(x)) is written as,

g(f(x)) = 4(3x² + x - 8) + 5

Simplify the function, then we have

g(f(x)) = 4(3x² + x - 8) + 5

g(f(x)) = 12x² + 4x - 32 + 5

g(f(x)) = 12x² + 4x - 27

To answer your question, Hailey is using the distributive property to simplify the calculation of 7(18). The distributive property allows us to break up a multiplication problem into smaller, more manageable parts.

Hailey has rewritten 18 as 10 + 8, and she will now use the distributive property to calculate 7 times each of these two numbers separately.
So, the two products that Hailey will add together to get the final product are 7 times 10 (which is 70) and 7 times 8 (which is 56).
To check her work, she can add these two products together:
70 + 56 = 126
So, using the distributive property and breaking up 18 into 10 and 8, Hailey can mentally compute the product of 7(18) as 126.

The probability that Melinda will be able to make an integer between 10 and 20 (inclusive) is 1/6.

The probability that Melinda will be able to make an integer between 10 and 20 (inclusive) with the two numbers she rolls can be calculated by determining the number of favorable outcomes and dividing it by the total number of possible outcomes.

To find the number of favorable outcomes, we need to identify the combinations of two numbers that will result in a two-digit number between 10 and 20. We can list these combinations as follows:

11, 12, 13, 14, 15, 16

Notice that we only have six favorable outcomes.

Now, let's determine the total number of possible outcomes when rolling two six-sided dice. Each die has six possible outcomes (1, 2, 3, 4, 5, 6), so the total number of outcomes is 6 multiplied by 6, which equals 36.

To calculate the probability, we divide the number of favorable outcomes (6) by the total number of possible outcomes (36):

Probability = Favorable outcomes / Total outcomes
Probability = 6 / 36
Probability = 1 / 6

Therefore, the probability that Melinda will be able to make an integer between 10 and 20 (inclusive) is 1/6.

Step-by-step explanation:

The round-off errors when measuring the distance that a long jumper has jumped are uniformly distributed between 0 and 5.8 mm.

To round values to 4 decimal places, we need to consider the range of possible values between 0 and 5.8 mm.

When rounding a measurement, we look at the digit in the fifth decimal place. If it is 5 or greater, we round up the fourth decimal place. If it is less than 5, we keep the fourth decimal place as it is.

Let's consider some examples to better understand this process:

1. If the measured distance is 2.3457 mm, the digit in the fifth decimal place is 7, which is greater than 5. Therefore, we round up the fourth decimal place to 2.3458 mm.

2. If the measured distance is 4.9999 mm, the digit in the fifth decimal place is 9, which is greater than 5. Again, we round up the fourth decimal place to 5.0000 mm.

3. If the measured distance is 3.2142 mm, the digit in the fifth decimal place is 2, which is less than 5. In this case, we keep the fourth decimal place as it is, resulting in 3.2142 mm.

By following this rounding process, we can round off the measured distances to 4 decimal places, taking into account the uniformly distributed round-off errors between 0 and 5.8 mm.

To use the chain rule, we first identify the outer function and the inner function. We then take the derivative of the outer function, leaving the inner function untouched. Finally, we multiply the result by the derivative of the inner function.In summary, the chain rule is an important tool in calculus used to find the derivative of composite functions.

However, I can give an explanation of the chain rule. The chain rule is a rule in calculus used to find the derivative of a composite function. A composite function is a function that is made up of two or more functions, where the output of one function is the input of another.  To use the chain rule, we first identify the outer function and the inner function. We then take the derivative of the outer function, leaving the inner function untouched. Finally, we multiply the result by the derivative of the inner function. For example, let's say we have the function f(x) = sin(3x). The outer function is sin(x) and the inner function is 3x. Using the chain rule, we take the derivative of the outer function, which is cos(3x), and leave the inner function untouched, which is 3. We then multiply the two together to get the derivative of f(x), which is f'(x) = 3cos(3x).
