Answer:
8
Step by Step Explanation:
log3 81= 4 since we raise 3 to the 4th power to get 81.
Log3 81+Log3 81 is equivalent to 4+4 which is equal to 8.
Step-by-step explanation:
equation -
(X+7) (x-1) =0
equation = x2 -x -7x -7 = x2 -8x -7
standard form = x2 -8x -7
factor form = (x+7) (x-1)
True
Note that:
The graph of sine and cosine functions are very similar. They only have a shift in the x -axis.
That is, sin x = cos (90 - x)
Since there is a great similarity between the sine and cosine graphs, and the secant graph is an inverse of the cosine graph, the graph of sine can be used to construct the graph of the secant function
Mathematically:
since sec x = 1 / cos x
and, cos x = sin (90 - x)
therefore, sec x = 1 / sin (90 - x)
The graphs of the sine and secant functions are attached to this solution
