Answer:
- using the rule given: 2.5
- using an exponential rule: 7
Step-by-step explanation:
Evaluating the linear rule given, for n = 1, we have ...
a1 = 7(1/2)(1) -1 = 7/2 -1 = 5/2 = 2.5
_____
We suspect you may intend the exponential function ...
an = 7(1/2)^(n-1)
Then, for n = 1, we have ...
a1 = 7(1/2)^(1 -1) = 7(1) = 7 . . . . the first term is 7
_____
When writing an exponential expression in plain text, it requires the exponential operator, a caret (^). If the exponent contains any arithmetic, as this one does, it must be enclosed in parentheses.
Answer:
The formula for compound interest is P (1 + r/n)^(nt), where P is the initial principal balance, r is the interest rate, n is the number of times interest is compounded per time period and t is the number of time periods.
Answer:
Step-by-step explanation:
3/4 divied by 15 = 1/20
The answer is A. a=(-1) b=(7)
You have to have a number that ends with three zeros. You have to look at the number formed by the last three digits. If this number smaller or equal to 500, you round down, meaning you just replace the three digits by three zeros, if it is bigger than 500, you round up, meaning you replace the three digits by three zeros and add one to the digit of the thousands.
Here, the last three digits form the number 470 which is smaller than 500 so the nearest thousand of 65470 is 65000.
