Answer: second option
Step-by-step explanation:
To find the inverse function of the given function f(x):
You need to:
Substitute 
into the function:
Now, you need to solve for "x", to do this, you must divide both sides of the function by 2:
Now, replace "x" with "y" and replace "y" with "x":
Therefore, substituting 
you get:
or 
Answer: Is -25/3 or -8.3 repeating.
Answer:
Step-by-step explanation:
AB = 8x + 5
BC = 5x² - 16
5x² - 16 = 8x + 5
5x² - 8x - 21 = 0
Quadratic formula
x = [8 ± √(8² – 4·5(-21))] / [2·5]
= [8 ± √484] / 10
= [8 ± 22] /10
= -1.4, 3
-1.4 is an extraneous solution.
x = 3
AB = 8x+5 = 29
AC = 58

Option (2)
Step-by-step explanation:
Radius of the circular base of the cone = 
Given in the picture,
Diameter of the circular base = 8 cm
Height of the cone = 6 cm
Therefore, radius of the cone = 
= 4 cm
Option (2) will be the correct option.
