Fractional index means "xth root of". Negative index means a fraction. So together, what it really means is:
![\frac{1}{\sqrt[5]{32}} = \frac{1}{2}.](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B%5Csqrt%5B5%5D%7B32%7D%7D%20%3D%20%5Cfrac%7B1%7D%7B2%7D.)
Answer:
Step-by-step explanation:instead, try making the subscripts and superscripts stand out:
n-1
a = a * r
n n-1
Believe me, it's worth the extra work to do this!!
Given the sequence -3, -6, -12, -24, you can easily see that the first term,
a is -3. The common factor is 2. Note how (-3)*2=-6, and so on.
1
So, a = -3 and r=2.
1
So the formula for this geometric sequence is
n-1
a = -3*2
n
Answer:
(D)What did Micah eat for lunch yesterday?
Step-by-step explanation:
A statistical question is a question for which the expected response varies. That is, we do not expect to get a single answer. Out of the given options,
Option D is not a valid statistical question as the response to the question will always be the same for a particular day,
If Micah ate cheesecakes for lunch yesterday, asking repeated times will not change the response.
I had a super-ugly equation that didn’t work, but it got me close. (24,000/12,000/12,000 or so)
Then I adjusted the numbers to make the money work.
I’m sorry I can’t help more.
24,000(25) + 14,200(20) + 9,800(15)
= 600,000 + 284,000 + 147,000 = 1,031,000
Section A = 24,000 seats
Section B = 14,200 seats
Section C = 9,800 seats
14,200 + 9,800 = 24,000 seats
Let
. Then
Meanwhile, since
, you have
.
It follows that
,
, and
, so that the quadratic fit for
that satisfies the given points is
Note that this is just the second-order Taylor polynomial for
about
.
