Graph and Label the Points on the coordinate plane below
Lapatulllka [165]
In order to graph these, you need to understand the X and Y axis.

The X-Axis contains the first number in your ordered pair, and goes left, right (horizontally) for example the first ordered pair you have.

(2,5 1/2). To do this, move 2 spaces to the right on your X-axis. now go 5 and a half spaces up, and plot the point.


(-2 1/2, 0.5) For this one, you move 2 and a half spaces to the left on the X-axis, and half a space up. put a point there.


(3.5, -4 1/2) move 3 and a half spaces to the right on your X-axis, and go 4 and a half spaces down. put a point there.

let me know if you have questions! :)

Let v be the volume of a sphere, s be the surface area of the sphere, and r be the radius of the sphere. which equation represen
MakcuM [25]
Let
v-------> <span> the volume of a sphere
s-------> t</span><span>he surface area of the sphere
r------> </span><span>the radius of the sphere

we know that
v=(4/3)*pi*r</span>³-----> v=(r/3)*4*pi*r²------> equation 1
and
S=4*pi*r²-----> equation 2

substitute equation 2 in equation 1
so
v=(r/3)*4*pi*r²-------> v=(r/3)*s

the answer is
the equation that <span>represents the relationship between these three measures
</span> v=(r/3)*s
