(4k+2)(k-2)/(k^2-4)(2k+1)
=2(2k+1)(k-2)/ (k^2-2^2)(2k+1)
Cancel out 2k+1
2(k-2)/(k-2)(k+2) using a^2-b^2=(a-b)(a+b)
cancel out k-2
2/k+2
Therefore numerator is 2
Answer:
It lies between 5 and 6
Step-by-step explanation:
x is the root of 30
Answer:
The scale factor for the resultant rectangle is units.
Step-by-step explanation:
Given two rectangles with sides 3 units and 7.5 units.
We have to find the scaling factors so that we can obtain bigger rectangle of 7.5 units from smaller rectangle of 3 units.
Scale factor is defined as the ratio of corresponding side of given figure to the corresponding side of resulting figure.
That is
Here,
Hence, the scale factor for the resultant rectangle is units.
The measure of angle <em>x </em> is 31 degrees.
See the attached drawing.
Start at the bottom, at the given 59° angle, and work your way up in the direction toward the angle <em>x </em>.
For this case, the first thing you should do is to know the following transformation:
pi radians = 180 degrees
Applying the transformation we have:
(13pi / 6) * (180 / pi) = 390 degrees
Then, in quadrant 1 we have:
390 - 360 = 30 degrees
Answer:
13 pi / 6 as a function of an angle in quadrant i is:
30 degrees
