The diagram shows you the radius of the circle is 1. It also tells you the value to use for π is 3. After you put these values in the formula, the rest is just arithmetic.
.. C = 2*π*r
.. C = 2*3*1
.. C = 6

Circumference is the roundabout measure of a circle. To find this, you need to use the equation listed in the bottom right-hand corner. R is your given radius (1) and instead of using the usual estimated number value for pi (3.14) you will use 3.

Multiply 2(1)(3) = 6

6 is the value of your circumference.

Which expression can be simplified to find the slope of the trend line in the scatterplot?

Maslowich

Answer:

1. $\frac{24-79}{12-2}$

Step-by-step explanation:

We have been given a graph of a scatter-plot and we are asked to find the correct expression than can be solved to find the slope of the trend line in the scatter-plot.

Since we know that slope of a line can be found by dividing the difference of the y-coordinates of 2 points on a line by difference of the x-coordinates of these same points.

$\text{Slope}=\frac{y_2-y_1}{x_2-x_1}$

We can see that (2,79) and (12,24) are two given points of our trend line. So let us substitute x and y-coordinates of our given points in slope formula to find the our desired expression.

$x_1=2$

$x_2=12$

$y_1=79$

$y_2=24$

$\text{Slope}=\frac{24-79}{12-2}$

Therefore, the expression $\text{Slope}=\frac{24-79}{12-2}$ can be solved to find the slope of the trend line in the scatter-plot and 1st option is the correct choice.

If the volume of a cube is 1,728 cubic inches, find the side length of each of its sides.

krok68 [10]

Recall that the volume of a cube equals (side)^3. We can create an equation to model this.

1728 in^3 = (side)^3

We can get the cube root of both sides.

12 in = side

Each side is 12 inches long.

4a+9=(-9+30-25). 4a+9=30-34. 4a+9=-4. 4a=-13. A=-3.25 :)
