Answer:
Correct choice is A
Step-by-step explanation:
If a function has an inverse, then there is at most one x-value for each y-value.
The tangent function is periodic with period
Hence, at each value for which
is defined,
for each integer n. Therefore, the function
does not have an inverse. Since tangent is not a one-to-one function, the domain must be limited. From examining the graph of the tangent function, we see that in each interval of the form

where k is an integer, the tangent function assumes every value in its range. Moreover, in each such interval, each y-value is achieved exactly once. Hence, we can create an invertible function by restricting the domain tangent function to one such interval. Such interval is an interval between two consecutive vertical asymptotes
and 
If there is 23 classrooms and each has 10 then you would have to times 23 by 10 - 23x10=230
Answer:
is equation of BC
Step-by-step explanation:
Given that AB and BC form a right angled triangle at point B.
i.e. BC is perpendicular to AB
Line AB contains two points (-3,-1) and (4,4)
Slope of AB =
Slope of BC would be -1/slope of AB since AB and BC are perpendicular
Slope of BC =\frac{-7}{5}
Also we got a point on BC as B.
Use point slope formula
