Answer:
−12/17
Step-by-step explanation:
This is the answer because:
1) First, convert 2 5/6 to an improper fraction
2 5/6 = 17/6
2) Next divide -2/1 and 17/6
3) The reciprocal of 17/6 is 6/17
4) -2/1 ÷6/17 is -12/17
Hope this helps!
<span>3) This one is a little different, since you're finding the angle instead of the side. You can denote the angle to be the variable x. Thus:
cos x = 14 / 26
Use a calculator to divide out 14/26, then round to four decimals.
cos x = 0.5385
Now go to the cosine chart and find which angle has the cosine 0.5385. It's a strange problem they gave you, because the chart doesn't have a value that matches it (kind of confusing if you ask me). But you can find two angles it is between. Notice that cos 57° = 0.5446 and cos 58° = 0.5299. Thus, the angle must be between those two. It turns out it is closer to 57°, so you can say:
x = 57° </span>
What you're really doing is finding the slope of the line between two points you need to calculate.
Because a=3, you're told that one point will always be (3, f(3)).
The second point will be (3+h, f(3+h)).
For the first point, f(3) = 7/3, so your first point is always (3, 7/3).
<u>For h=1</u>
The x-value of your second point is a+h, or 3+1 = 4 in this case.
f(4) = 7/4.
So the average rate of change, aka the slope of the line between (3, 7/3) and (4, 7/4), is the usual slope formula:
In this h=1 situation, that becomes:
You're repeat this process for each new h-value.
