Answer:
^geometric sequence^
<h2>YES, it belongs to a geometric sequence because it has a ratio. and how to find ratio is:</h2>
a2 : a1
=9 : 3= 3
or a3 : a2
=27 : 9= 3
or a4 : a3
= 81 : 27= 3
so, the anwer is yes;3 (b)
<h3>FINALLY FOUND, MODERATOR!!</h3>
-2(a - 8) + 6a = 36
-2(a) + 2(8) + 6a = 36
-2a + 16 + 6a = 36
-2a + 6a + 16 = 36
4a + 16 = 36
- 16 - 16
4a = 20
4 4
a = 5
electricity comes from electrons, does morality come from morons? No, you're thinking of mormality. That is true, especially in the US. ... This means that the stupider a group is overall, the less moral they are expected to beon:
On a right triangle, to find one missing side you can use this equation
a^2 + b^2 = c^2
a and b are the sides next to the right angle, and c is the hypotenuse (side not connected to right angle).
You first need to find the length of the dotted line before finding x. This is because to be able to use the above formula, you have to know the length of two out of three of the sides.
To solve the length of the dotted line, note that it also makes a triangle with the 5 unit line and the 5 √5 unit line. You can plug these numbers into the formula.
(5)^2+b^2=(5 √5)^2
25+b^2=125
b^2=100
b=10
Now that you know the length of the dotted line is 10 units, you can now solve for x
(20)^2+(10)^2=x^2
400+100=x^2
500=x^2
x= √500, which equals 22.361
