Answer:

Exponential decay function

Step-by-step explanation:

The given table represents some function between x and y:

x - 3 - 6 - 9 - 12

y - 2401 - 343 - 49 - 7

We are required to find if it's exponential growth, decay, or neither.

An exponential function is identified because each term is calculated as the previous term multiplied by a constant factor.

The linear relationship is identified because each term is calculated as the previous term plus a constant difference.

Note the values of x grow three by three and the values of y are constantly divided by 7 or multiplied by 1/7.

There is a common factor and not a common difference. Since the common factor is less than 1, the function is exponential decay.

Bonus: The exponential function is:

$\displaystyle y= 16807*\left(\frac{1}{7}\right)^{x/3}$

What is the equation of the circle?

MakcuM [25]

Answer:

○ $\displaystyle (x - 4)^2 + (y + 2)^2 = 25$

Explanation:

Accourding to one of the circle equations, $\displaystyle (x - h)^2 + (y - k)^2 = r^2,$ the centre of the circle is represented by $\displaystyle (h, k).$ Moreover, all negative symbols give you the OPPOCITE TERMS OF WHAT THEY REALLY ARE, so you must pay cloce attention to which term gets which symbol. Another thing you need to know is that the radius will ALWAYS be squared, so no matter how your equation comes about, make sure that the radius is squared. Now, in case you did not know how to define the radius, you can choose between either method:

Pythagorean Theorem

$\displaystyle a^2 + b^2 = c^2 \\ \\ 4^2 + 3^2 = r^2 \hookrightarrow 16 + 9 = r^2 \hookrightarrow \sqrt{25} = \sqrt{r^2} \\ \\ \boxed{5 = r}$

Sinse we are dealing with length, we only desire the NON-NEGATIVE root.

Distanse Equation

$\displaystyle \sqrt{[-x_1 + x_2]^2 + [-y_1 + y_2]^2} = d \\ \\ \sqrt{[-7 + 4]^2 + [-2 - 2]^2} = r \hookrightarrow \sqrt{[-3]^2 + [-4]^2} = r \hookrightarrow \sqrt{9 + 16} = r; \sqrt{25} = r \\ \\ \boxed{5 = r}$

Sinse we are dealing with distanse, we only desire the NON-NEGATIVE root.

Write an equation that represents the line. Use exact numbers.

Alja [10]

y=1.5x+3

Observing the graph

Let,

A(0,3) -----> this point is the y-intercept of the line

B(2,6)

We know that

The equation of the line into slope intercept form is equal to

y = mx + c

where

m is the slope

b is the y-coordinate of the y-intercept

In this problem

b=3

Find the slope of the line m

The formula to calculate the slope between two points is equal to

m = y2-y1 / x2-x1

substitute the values

m = 6-3 / 2-0

m = 3/2

m = 1.5

The equation of the line is

y= 1.5x+3

A) 16/40 reduces to 2/5 so 2/5 is correct
b) theoretically you would get heads up 20/40 times which reduces to 1/2
