Supplementary angle must add up to 180 so the supplement will be 108 degrees. 180-72=108.

Is the set of numbers one 1,5,25 and 125 a geometric sequence

Strike441 [17]

Short answer: Yes.
Each member of the sequence is multiplied by 5 to get to the next member of the sequence.

Find the general equation.
tn = a*5^(n - 1)

Example
t4 = 1*5^(4 - 1)
t4 = 1*5^3
t4 = 125 just as the sequence shows.

t5 = 1^5^4
t5 = 625 Any member of the sequence can be found this way.

The cylinder is 10 meters wide and the volume is 300 cubic meters what's the height of the cylinder?

daser333 [38]

Cylinder is 10 meters wide, so its diameter is 10 meters. You get radius of it by dividing 10 by 2, which equals 5.
As you count volume of cylinder from that equation
$V=A*h= \pi r^{2}*h$
You get an equation to count height:
$h= \frac{V}{ \pi r^{2} }$
h≈3.82 meters
