Answer:

Step-by-step explanation:

$\dfrac{2}{\dfrac{1}{8}}=2\cdot\dfrac{8}{1}=\dfrac{2\cdot 8}{1}=16$

There are numerous ways to work a problem like this. One is shown above, where we multiply by the inverse of the denominator.

For this you can always use a calculator. Be sure to use parentheses around the denominator fraction.

konstantin123 [22]

Answer:

131.87-23.24=108.63

Step-by-step explanation:

To solve this problem, let's line up the problem. To make it easier, we can start by ignoring the decimals.

13187

- 2324

______

10863

And then, since there were decimals in the first place, we have to add them back in.

10863→108.63

Answer:

$b = 0.0138$

Step-by-step explanation:

Given

Regression Equation:

$DD=2.69+0.0138D$

Required

Determine the slope of the regression line

The equation of regression is of the form

$Y = a + bX$

Where b represents the slope;

Compare $Y = a + bX$ to the given equation

$DD=2.69+0.0138D$

We have that:

$Y = DD$

$a = 2.69$

$b = 0.0138$

$X = D$

Hence; the slope is:

$b = 0.0138$

21. Paul has $900 to invest in a savings account that has an annual interest rate of 1.8%, and a money market account that pays

Iteru [2.4K]

The polynomial that gives the interest earned after a year will have variables, exponents and constants that are joined by operators.

The interest earned after one year is 0.018·x

Reasons:

The amount Paul has to invest = $900

The annual interest rate from the savings account = 1.8%

The amount the money market account pays per year = 4.2 %

Required: The polynomial for the interest Paul earned by investing x dollars in the savings account.

Solution:

The interest earned is found using the compound interest formula as follows;

$\displaystyle A = \mathbf{P \cdot \left(1 + \frac{r}{n} \right)^{n \cdot t}}$

Where;

A = The amount in the account after one year

P = The original amount invested = x

r = The interest rate offered on the investment = 1.8% = 0.018

t = The time of the investment = 1 year

n = The number of times of application of the interest per period = Once per year

Which gives;

Interest = Amount earned = A - P

Therefore;

$\displaystyle Interest, \ I = \mathbf{P \cdot \left(1 + \frac{r}{n} \right)^{n \cdot t} - P}$

Plugging in the values gives;

$\displaystyle I = x \cdot \left(1 + \frac{0.018}{1} \right)^{1 \times 1} - x = x \cdot 1.018^1 - x = 1.018 \cdot x - x = 0.018 \cdot x$

The polynomial equation is therefore;

Interest, I = 0.018·x

Using the simple interest formula, we have;

$\displaystyle Interest = \mathbf{\frac{P \times r \times t}{100}}$

Which gives;

$\displaystyle Interest = \frac{x \times 1.8 \times 1}{100} = 0.018 \cdot x$

Interest earned by investing in the savings account for one year, I = 0.018·x

The polynomial representing the interest earned is I = 0.018·x
