8: slope is 1/2 and y intercept is 0
9: slope is 7/4 and y-intercept is 0
It's hard to type and hard to read the "inverse tangent" function, as you've seen (above).
So, use "arctan x" instead.
Then the problem becomes: "differentiate cos (arctan x)."
You must apply first the rule for differentiating the cosine function, and next apply the rule for differentiating the arctan function:
(d/dx) cos (arctan x) = - sin (arctan x) * [1/(1+x^2)]
Answer:
the figure is missing. please provide the figure.
Answer:
<h2>B. 468</h2>
Step-by-step explanation:
We have

If |r| < 1, then the formula of a sum of an infinite geometric sequence is:

Substitute:

It is basically a square attached by a small rectangle. So figure out the area of the square and add it to the area of the rectangle and don't forget to label your answer. Hope this helped :)
