318.9 in scintific notation

1 answer:

3 0

Scientific notatino is
(number that is greater than or equal to 1 and less than 10) times (10^x)

so
318.9
we need to make it less than 10
move decimal 2 places to left
3.189

to make it the same number, we multipl it by 10^2 to make it go back

scientific is
3.189 times 10^2

What is the additive inverse of 18xy?

Cloud [144]

An additive inverse is the value you can add to a given value such that the sum is "0"..

Your answer is choice A
18xy + (-18xy) = 0 Since these are like terms.. the key here is understanding that like terms must have the same exact variables raised to the exact same powers. We can add like terms. We cannot add unlike terms.

What did sin theta/theta whisper worksheet answer key worksheet?

djyliett [7]

To evaluate
$\lim_{\theta \to 0} \frac{\sin\theta}{\theta}$

First, we input 0, for theta in the function to obtain:
$\frac{\sin0}{0} = \frac{0}{0}$

This is an indeterminate form.

So, we apply L'Hopital's rule by differentiating the numerator and the denominator as follows:

$\lim_{\theta \to 0} \frac{\sin\theta}{\theta}=\lim_{\theta \to 0} \frac{ \frac{d}{d\theta} (\sin\theta)}{\frac{d}{d\theta}\theta} \\ \\ =\lim_{\theta \to 0} \frac{\cos\theta}{1}=\cos0=1$
