Answer:
Center: (-5,10)
Radius: 2
Step-by-step explanation:
The equation of the circle in center-radius form is:
Where the point (h,k) is the center of the circle and "r" is the radius.
Subtract 121 from both sides of the equation:
Add 10x to both sides:
Make two groups for variable "x" and variable "y":
Complete the square:
Add inside the parentheses of "x".
Add inside the parentheses of "y".
Add and
to the right side of the equation.
Then:
Rewriting, you get that the equation of the circle in center-radius form is:
You can observe that the radius of the circle is:
And the center is:
Answer:
Graph (2).
Step-by-step explanation:
Given question is incomplete: Find the complete question in the attachment.
Given : f(x) = -
g(x) = - 1
To find : The graph showing f(x) = g(x)
If the given functions f(x) = g(x)
= 1
x = -2
That means both the functions have the same value at x = -2
f(-2) = g(-2) = -1
In other words, both the lines will intersect at a point (-2, -1).
From the given graphs,
Graph number (2) shows the required results.
A straight line g(x) = -1 parallel to x- axis and another straight line f(x) = , intersect each other at (-2, -1).
Therefore, Graph (2) will be the answer.
Answer:
The amplitude is
Step-by-step explanation:
Trigonometric function:
A trigonometric function has the following format:
or
In which the amplitude is A and the period is
Amplitude of y = 1/2 * cos 5x
The multiplier is 1/2, so this is the amplitude.
