Answer is: even
This function’s graph is symmetric with respect to the y-axis therefore, this function is even.
X+8/4-x+5/4
The first term in the series is a positive "x", and the third one is a "-x". Since these are opposites, they cancel out
x+8/4-x+5/4
8/4+5/4
13/4
4 1/4
There are two (equivalent) formulas for the circumference of a circle:
C = 2 pi r, where r is the radius of the circle
C = pi d, where d is the diameter of the circle
In this particular problem, however, we're dealing with arc length. For the shown central angle "theta" = 160 degrees, the arc length is 42 cm.
Knowing this enables us to calculate the radius or diameter of the circle.
Arc length = s = (radius) (central angle, in radians, not degrees)
First, convert 160 degrees to radians: 160 deg pi rad
----------- * ------------ = (8/9) pi rad
1 180 deg
Then 42 cm = r *(8/9) pi rad
Solve for the radius (r): divide 42 cm by (8/9) pi rad
Then use the formula for circumference introduced earlier:
C= 2 pi r Substitute [42 cm / ( (8/9) pi rad )] for r.
Simplify your result, and you will then have the circumference, C, in cm.
Answer:
DD
Step-by-step explanation:
If you distribute the 2 you get 12.2x + 14 so D
Step-by-step explanation:
starting at (1,-2) the point will move to the left 2 to be reflected over the y-axis and will then be at (-1,-2). then reflecting over the x-axis will move it up 4 and end up at (-1,2).
