First find the area of the circle using A=pi*r^2
pi*36
Then divide this by 4 because the shaded region is 1/4 of the circle
(36*pi)/4=9*pi
Final answer: B
Answer:
10 problems
Step-by-step explanation:
This is the answer because:
1) We have to solve for what 20% of 50 is since she finished 20% of her test:
20% of 50 = 10
× 
= 
= 10
Therefore, the answer is 10 problems.
Hope this helps! :D
Hey there!
A parent function is the most basic function in any group of functions. For example, f(x) = x^2 is the parent function for quadratic functions, and y = x is the parent function for linear functions. When there's nothing added, subtracted, multiplied, or divided to the function.
For A, we see that we're multiplying 2 times 3^x, and since this is not any alternation of any parent function or any parent function in particular, we can rule it out.
For B, we see that 3 is being added to x^2, so it cannot be a parent function.
For C, we see that 2 multiplied to e, therefore it cannot be the mot basic function.
Finally, for D, we see a function that looks similar to the quadratic parent function and is very simple itself. Any alterations to this is any other quadratic function
Your answer is D.
Hope this helps!

One Answer: Choice C) 0 < x < 1
==================================================
Explanation:
Let's go through the answer choices one at a time.
- Choice A represents an increasing interval since the graph goes uphill as we move from left to right. The line through the points (-2, f(-2)) and (-1.5, f(-1.5)) has a positive slope. We can rule out choice A.
- Choice B is a similar story to choice A. The graph goes uphill when we move from x = -1 to x = 0, so the graph is increasing on the interval -1 < x < 0. We can rule out choice B.
- In contrast, choice C is a decreasing interval. Going from x = 0 to x = 1 has us move downhill. Choice C is the only answer.
- Choice D is false because choice C was shown to be true.
