Answer: (x 1 ,y 1)=(2,3) and (x 2,y 2)=(4,7)by midpoint formula, coordinates of mid point =( 2x 1+x 2, 2y 1 +y 2)=( 22+4, 23+7 )=( 26 , 210)=(3,5).

Step-by-step explanation: Hope this helps

Here's a graph of a linear function. Write the equation that describes that function. (Express it in slope-intercept form.)

rusak2 [61]

Answer:

$y=\frac{1}{2}x+4$

Step-by-step explanation:

The equation of a linear function in a slope-intercept form is written as

$y=mx+q$

where

m is the slope of the line

q is the y-intercept

We proceed as follows. First of all, we find the y-intercept, which is the value of y at which the line touches the y-axis.

From the graph, we see that this occurs at y = 4, therefore the y-intercept is

$q=4$

Now we have to find the slope. We do that by choosing two points along the line, with coordinates $(x_1,y_1)$ and $(x_2,y_2)$ and by using the equation

$m=\frac{y_2-y_1}{x_2-x_1}$

Here we take the two points:

(0,4)

(-8,0)

So the slope is

$m=\frac{4-0}{0-(-8)}=\frac{1}{2}$

Therefore, the equation of the line is

$y=\frac{1}{2}x+4$

When a spherical balloon is filled with air, it has a radius of 3 inches. Which of these gives the best estimate for the volume

marysya [2.9K]

By definition, the volume of a sphere is given by:
V = (4/3) * (pi) * (r ^ 3)
where,
r: radius of the sphere.
Substituting we have:
V = (4/3) * (pi) * ((3) ^ 3) = 113.08 in ^ 3
answer
the best estimate for the volume of air in the balloon in cubic inches is
C. 113.1
