A finite geometric series is the sum of a sequence of numbers. Take the sequence 1, 2, 4, 8, β¦ , for example. Notice that each number is twice the value of the previous number. So, a number in the sequence can be represented by the function f(n) = 2nβ1. One way to write the sum of the sequence through the 5th number in the sequence is β5n-12n-1. This equation can also be written as S5 = 20 + 21 + 22 + 23 + 24. If we multiply this equation by 2, the equation becomes 2(S5) = 21 + 22 + 23 + 24 + 25.
What happens if you subtract the two equations and solve for S5? Can you use this information to come up with a way to find any geometric series Sn in the form βan-1bn-1?

The distribution of the amount of money spent by students for textbooks in a semester is approximately normal in shape with a mean of $235 and a standard deviation of $20. according to the standard deviation rule, how much did almost all (99.7%) of the students spend on textbooks in a semester?

He graph of f(x) = |x| is stretched by a factor of 0.3 and translated down 4 units. which statement about the domain and range of each function is correct? the range of the transformed function and the parent function are both all real numbers greater than or equal to 4. the domain of the transformed function is all real numbers and is, therefore, different from that of the parent function. the range of the transformed function is all real numbers greater than or equal to 0 and is, therefore, different from that of the parent function. the domain of the transformed function and the parent function are both all real numbers.
