Answer:
Wait From What I See Aren't You Just Supposed To Put A Name And Date?
Step-by-step explanation:
Sum of n terms = a1 (r^n-1/ (r-1)
Sum of first one = 3 * (4^5 - 1) / 3 = 1023
.. 2nd = 5 * (6^2 - 1) / 5 = 35
.. 3rd = 5 ^4 - 1 / 4 = 156
.. 4th = 4 * (5^4 - 1) / 4 = 624
So in increasing order its 2nd, 3rd, 4th and first.
A=36 1/2*8*9 this is how you would figure out A
Answer: 
Step-by-step explanation:
Given the right triangle in the image, you need to remember the following identity:
Observe the triangle. You can identify that:
Then, knowing these values, you can substitute them into :
Finally, you have to solve for "x".
Therefore, the value of "x" rounded to the nearest tenth is:
Answer:
2.1 months
Step-by-step explanation:
Let x represent the number of months
Set up expressions to represent the cost of each Internet provider
40x + 39 will represent the first one
30x + 60 will represent the other
Set these equal to each other and solve for x:
40x + 39 = 30x + 60
10x + 39 = 60
10x = 21
x = 2.1
So, the cost will be the same in 2.1 months
