Answer:

A(x) = 20000(0.88)^x

Step-by-step explanation:

The general form of these exponential equations is ...

A(x) = a·b^x

where 'a' is the initial value, and b is the annual growth factor. x is the elapsed time in years.

The growth factor is ...

growth factor = 1 + growth rate

Here, the growth rate per year is -12%, so the growth factor is ...

b = 1 -12% = 88% = 0.88

Of course, the initial value is a=20,000, so the equation is ...

A(x) = 20000(0.88)^x

The sum of three consecutive even integers is 54. Find all three integers.

matrenka [14]

A good way to find the answer to these questions is to find it algebraically. Let's call the first number 'n'.
n + (n + 2) + (n + 4) = 54
3n + 6 = 54
3n = 48
n = 16
Therefore the numbers are 16, 18, 20

Answer:

see below (upper right)

Step-by-step explanation:

A function has no repeated x-values in the relation. The only table with unique x-values is the one shown below. It is upper right in your picture.

Least square regressions are used to find the equation of best fit between two variables.

The equation of the least-squares regression line is: $\mathbf{y = 9.414 - 0.213x}$

The given parameters are:

$\mathbf{\bar x = 8}$

$\mathbf{\sigma_x = 4.47}$

$\mathbf{\bar y = 7.71}$

$\mathbf{\sigma_y = 1.20}$

$\mathbf{r = -0.793}$

The equation of the least-squares regression line is represented as:

$\mathbf{y = a + bx}$

Where:

$\mathbf{b = r \times \frac{\sigma_y}{\sigma_x}}$

$\mathbf{a = \bar y - b\bar x}$

So, we have:

$\mathbf{b = r \times \frac{\sigma_y}{\sigma_x}}$

$\mathbf{b = -0.793 \times \frac{1.20}{4.47}}$

$\mathbf{b = -0.213}$

$\mathbf{a = \bar y - b\bar x}$

$\mathbf{a = 7.71 - (-0.213) \times 8}$

$\mathbf{a = 9.414}$

So, the equation is:

$\mathbf{y = a + bx}$

$\mathbf{y = 9.414 - 0.213x}$
