The length of tom's block on his map is 11.25 inches
Answer:
A
Step-by-step explanation:
To find an inverse function you switch f(x) and x, and solve for f(x) (in this case you also rename it to g(x) )
inverse of y=(x-4)/5 is
5x = x -4
x = 5x + 4 so A works
Explanation:
First, we need to find the values of the sine and cosine of x knowing the value of tan x and x being in the 3rd quadrant. Since tan x = 5/12, using Pythagorean theorem, we know that
Note that both sine and cosine are negative because x is in the 3rd quadrant.
Recall the addition identities listed below:
Therefore, the expression reduces to
