Answer:
√260 and √132
Step-by-step explanation:
use pythagoreans theorem and you can replace a and b or a and c
8^2+14^2=x^2
64+196=x^2
260=x^2
x=√260
8^2+x^2=14^2
64+x^2=196
x^2=132
x=√132
Answer:
-338
Step-by-step explanation:
So we have the sequence:
5, -2, -9, -16...
First, note that this is an arithmetic sequence.
This is because each individual term is the previous term <em>added</em> by a common difference.
We can see that this common difference is -7, because each subsequent term is 7 <em>less</em> than the previous one. For example, 5 minus 7 is -2, -2 minus 7 is -9, and so on.
So, to find the 50th term, we can write an explicit formula for our sequence.
The standard form for the explicit formula for an arithmetic sequence is:

Where a is the initial term, d is the common difference, and n is the nth term.
We can see that our initial term a is 5. And we also already determined that the common difference d is -7. So, substitute:

Now, to find the 50th term, all we have to do is to substitute 50 for n. So:

Subtract within the parentheses:

Multiply:

Subtract:

So, the 50th term is -338.
And we're done!

Answer:
<h2><em><u>
3,180 words in the hour</u></em></h2>
Step-by-step explanation:
First, you have to figure out how many words he types in one minute. Then, have to multiply by the number of minutes. So,
Number of words per minute:
742 = Total number of words in 14 min
14 = time given
<em><u>742/14 = 53 words per minute</u></em>
Number of Words in 1 hour:
53 = words per min
60 = number of minutes
53*60 = 3,180
<h2><em><u>
3,180 words in one hour.</u></em></h2><h2><em><u>
</u></em></h2>
