Answer:
The formula for the volume of a washer requires both an inner radius r1 and outer radius r2. We'll need to know the volume formula for a single washer. V = π (r22 – r12) h = π (f(x)2 – g(x)2) dx. As before, the exact volume formula arises from taking the limit as the number of slices becomes infinite.
False bc if u substitute the values in, -7 + 8, the answer is not less than 5. The answer will be equal to 5, so the test point is not a solution to the linear inequality.
Answer:
Step-by-step explanation:
All she needs to know is that a reflection across the x-axis is when the x coordinate stays the same and the y-coordinates change.
Hope this helped.
Hello from MrBillDoesMath!
Answer:
m = 0
b = 22
Discussion:
I will ignore the duplication of the point (15,22) and "y=mx+b" mentioned in this question.
A line parallel to the x axis is of the form
y = <constant>.
Since the line passes through (15,22), the above constant must be 22. That is,
y = 22 = 0x +22 = mx + b
so m = 0 and b = 22
Thank you,

Step-by-step explanation:
I didn't know this off of the top of my head, and I used Google to help me. Simply searching "30 60 90 right triangle" gave me a few very helpful links. For future reference, if no one is answering here, Google may be your friend.
The (credible) site that I found tells me
"The basic 30-60-90 triangle ratio is:
Side opposite the 30° angle: x
Side opposite the 60° angle: x * √3
Side opposite the 90° angle: 2x"
The side opposite the 30 degree angle is a value called "x" according to this site. This would mean that y is x, which is confusing, so we can just say that the value of y is y (if you want to go a little more in depth, I will simply be referring to what the site refers to as "x" as "y"). To begin, the side opposite the 30 degree angle, which is 8√3, is y * √3. This means that y is 8. Then, the remaining side is 2*y, which is 16.
Please let me know if you have any further questions or concerns.
