Answer:

Step-by-step explanation:
Use the distance formula!

If we plug in the coordinates:

That's our answer!
C = 2 x pi x r
C = 2 x 3.14 x 3 = 18.84
18.84 x .5 = 9.42
10 + 14 + 7.21 + 9.24 = 44.45in squared
Answer:
1.5(d)
Step-by-step explanation:
Step-by-step explanation:


To solve this system of equations, let's first add the equations together:




There are no values of
that will make this equation true, so the lines never intersect, and therefore there are no solutions to this system of equations.
Answer:
V' = (-1, -4)
Step-by-step explanation:
the original point V (4, -1) is 4 units to the right and 1 unit down.
now we turn this 90° clockwise (upper right to down to upper left).
that means the right part of the x-axis turns into the bottom part of the y-axis, and the bottom part of the y-axis into the left part of the x-axis.
so, positive x turns into negative y, and the negative y turns into negative x.
therefore, (4 -1) turns into (-1, -4).
