A geometric sequence is a sequence with a common ratio multiplied by previous term to give the next. Lets call x the common ratio, so we know that 4 was multiplied by x to give the second term, and so forth until it was multiplied again and again by x until the 16384 was reached which happens to be the 13th term, that means that 4x was multiplied by x 12 more times to give 16384, that is:
4x^12 = 16384
x^12 = 4096
x = 4096^-12
x = 4.48 x 10^-44
that is the common ratio
Answer:
2677
Step-by-step explanation:
Let's make this easier first of all:
a^2-y^3(a-y^2)y^2
a^2-y^5(a-y^2)
a^2-ay^5+y^7
(-2)^2-(-2)(3)^5+3^7
4-(-2*243)+2187
4-(-486)+2187
4+486+2187
490+2187

Answer:
2
Step-by-step explanation:
If we take 1 and add another 1, you will get 2
Answer:
8x+12
Step-by-step explanation:
To find the Perimeter, we need to add all 4 sides together. In this case, we would do:
x+4+x+4+3x+2+3x+2
Now, we have to combine like terms.
x+x+3x+3x=8x.
4+4+2+2=12
The final answer would be 8x+12 or 12 +8x.
You can put whichever answer you want because it doesn't matter.
Hope this helps!

Answer:
Area and height
Step-by-step explanation:
Required
What must be known to calculate volume
To calculate volume, you need:
This is proved by the formula below:
The volume of a solid is:
i.e. the product of the area of the solid and the height of the solid.
So, from the formula above: the height and the area must be known
