Given:
A certain function h(x) contains the point (8,-2).
To find:
The value of 
.
Solution:
If a function is defined as
Then, its inverse is defined as
It is given that, a certain function h(x) contains the point (8,-2). It means, its inverse 
contains the point (-2,8). So, the value of inverse function is 8 at x=-2, i.e.,
Therefore, the value of is 8.
-- the greatest common factor of the 15, the 9, and the 24 is 3 .
-- the greatest common factor of the b⁴, the b⁵, and the b³ is b³.
-- the greatest common factor of the c³, the c², and the c¹, is c¹.
-- the greatest common factor of the d², the d¹, and the d³ is d¹.
-- SO, the greatest common factor of the whole thing is ( 3 b³ c d ) .
Can you factor that out of the big mess ?
Please try it.
You should get (3 b³cd) (5 bc²d - 3 b²c - 8 d²) .
Answer:
Width equals 11, and length equals 12.
Step-by-step explanation: It is helpful to memorize your multiplication tables up to 12. I personally couldn't figure out a formula for this, but I knew that 12 x 11 equals 132, and the length is greater than the width, so length is 12 and width is 11. Hopefully somebody else can figure it out. P.S. I meant the formula, not the answer, my answer is correct.
C. Survey all of the customers who use the cell phone service in one city selected at random.
A sample survey normally provides larger scope than a census.
It is critical that researchers accepts the population on a case-by-case basis and test the sample for consistency before moving ahead with the survey.
