A mapping system is a way of describing
a C. Preimage of a figure. Mapping statements are known to define the range of
data sources thus showing all the data. While on the other hand, preimage (in
Mathematics) meaning is that set of all the elements of the domain that maps to
the members of S.

Step-by-step explanation:
by moving the decimal 2 times to the right
Correct me if I’m wrong but I believe it is C
Hi there! The answer is A.

To get a proper idea of the type of function this formula represents we work out the parenthesis.
Working out the parenthesis can for instance be done using rainbow technique.

We can now see sinilarities between this function an the general function of a line in slope intercept form

The function t therefore describes a line with slope 2 and y-intercept 4. Therefore the answer is A.
Answer:
b= 0.9
Step-by-step explanation:
first you find angle B: 180-90-25=65
then you will do law of sine- sin A/a=sin B/b=sin C/c
sin(90)/1=sin 65/b
sin(90)*b=sin(65)*1
sin(90)*b=0.9
b=0.9/sin(90)
b= 0.9
