Answer:
Step-by-step explanation:
We are given the following in the question:
where r and r are the radius of the circle.
General equation of circle:
where(h,k,j) is the center of the circle and r is the radius of circle.
If the circle is centered at origin, then,
Equation of circle with radius R centered on origin
Inequality to describe the region that consist of all points lying between the sphere of radius r and R but not on the sphere is given by:
Answer:
The answer is D
Step-by-step explanation:
A cant be right because the graph isn't a straight line.
B cant be right because from 0 to 60 the graph the line goes at a(n) upward slope not a straight line.
Although the first part of question c is right, the second part is wrong. From 50-90 the ling goes at a downward slope via decreasing, which isn't equal like it said so question C is wrong.
So the correct answer is D
Answer:
![\sqrt[8]x = x^\frac{1}{6}](https://tex.z-dn.net/?f=%5Csqrt%5B8%5Dx%20%3D%20x%5E%5Cfrac%7B1%7D%7B6%7D)
Step-by-step explanation:
Given:
![\sqrt[6] x](https://tex.z-dn.net/?f=%5Csqrt%5B6%5D%20x)
Required
Represent as an exponent
In indices, we have:
![\sqrt[n]x = x^\frac{1}{n}](https://tex.z-dn.net/?f=%5Csqrt%5Bn%5Dx%20%3D%20x%5E%5Cfrac%7B1%7D%7Bn%7D)
By comparison:
![\sqrt[8]x = \sqrt[n]x](https://tex.z-dn.net/?f=%5Csqrt%5B8%5Dx%20%3D%20%5Csqrt%5Bn%5Dx)
Apply this law to the given expression:
We have:
