Answer:
f^-1 (x) = 1/2x -5/2
Step-by-step explanation:
To find the inverse of a function, exchange x and y and then solve for y
y = 2x+5
Exchange x and y
x = 2y+5
Solve for y
Subtract 5 from each
x-5 = 2y+5-5
x-5 = 2y
Divide by 2
(x-5)/2 = 2y/2
1/2x - 5/2 = y
f^-1 (x) = 1/2x -5/2
IT is A 44 degrees i hope this helps
Answer:
7.6
Step-by-step explanation:
Alright, we're using a trig function, Tan (angle) = opposite side / adjacent side
In our case tan(27) = x/15
if we multiply both sides by 15 we get
15 tan (27) = x
which means x =7.6 (rounding to the nearest tenth)
