What is the perimeter of a polygon with vertices at (−2, 1) , ​ (−2, 7) ​, (1, 11) , ​ (4, 7) ​ ​, and ​​ ​ (4, 1) ​ ?
Sholpan [36]

Each edge is given by the distance formula, which is the Pythagorean Theorem. When one of the coordinates is the same, we can shortcut that.

A(−2, 1) , B(−2, 7)​, C(1, 11), D(4, 7)​, E(4, 1)

AB=7-1=6

BC=\sqrt{(1 - -2)^2 + (11-7)^2}=5

CD=\sqrt{(4 - 1 )^2 + (11-7)^2}=5

DE=7-1=6

EA= 4 - -2 = 6

\textrm{perimeter} = 6+5+5+6+6=28

Answer: 28

What is the effect on the volume of a sphere if the radius is divided by 3?
Neko [114]

For this case we have by definition, that the volume of a sphere is given by:

V = \frac {4} {3} \pi * r ^ 3

Where:

r: It is the radius of the sphere

If the radius is divided by 3 we have:

\frac {r} {3}:

V = \frac {4} {3} \pi * (\frac {r} {3}) ^ 3\\V = \frac {4} {3} \pi * \frac {r ^ 3} {27}\\V = \frac {4} {81} \pi * r ^ 3

ANswer:

the volume decreases considerably because the denominator increases
