F - because you must move the decimal place 9 spaces to the left in order to have only a single digit in front of the decimal place. (There can never be more than one otherwise it is no longer scientific notation.
Answer:
we know that
The radicand of the function must be greater than or equal to zero
so
the solution is the interval---------> [-6,∞)
therefore
the answer is
The domain are all values of x greater than or equal to minus six
Answer: Hello there!
we have the equation a(n) = (1/2)n - 1 for n ≥ 1
First we need the first five terms:
a(1) = (1/2)*1 - 1 = -1/2
a(2) = (1/2)*2 - 1 = 0
a(3) = (1/2)*3 - 1 = 1/2
a(4) = (1/2)*4 - 1 = 1
a(5) = (1/2)*5 - 1 = 3/2
then we can see that each term is 1/2 bigger than the previous one, then a recursive relation can be written as:
a(n) = a(n-1) + 1/2
where n ≥ 2, and a(1) = -1/2
That would be 9/12 left over. Actual Math: Change 1/6 to 2/12. Why you may ask? Well, they are both equivalent. Then, add 1/12 + 2/12 which equals 3/12. After that,subtract 12/12 (total) - 3/12. You should get 9/12, your answer to the problem. So, Jonathan has 9/12 of his favorite pasta left over.
