Angle of fire in degrees = 90 + 30 =120 degrees
Angle of fire radians =180 degrees = π
120* π/180=120π /180 OR 4π/6 OR 2π/3
Answer:
inverse f-1 (x) = x/18
Step-by-step explanation:
To find the inverse of a function f-1 (x), we represent f(x) by y or let f(x) = y
then make x the subject of the formula,
f(x) = 18x
Let f(x) = y
hence Y = 18x, make x the subject of the formula, do that by dividing both sides by 18,
Y/18 = x or x = Y/18
Interchanging or swapping x and y, therefore f-1 (x) = x/18
therefore, F(x) = 18x, the inverse f-1 (x) = x/18
