Answer: f(f(f(x)))=8x-7

Step-by-step explanation:

Since we were given f(x) and f(f(x)), We plug that into f(x) again to get f(f(f(x))).

2(4x-3)-1                          [distribute]

8x-6-1                              [combine like terms]

The ramp shown in the diagram has a rise of 225 cm and it makes an angle 40° with the floor.
Kazeer [188]

The length of the ramp calculated using Pythagoras is approximately 350 cm

From the diagram attached :

  • Height of ramp = opposite = 225 cm

  • Angle of inclination, θ = 40°

Using Pythagoras ; the length of the ramp can calculated as follows :

Sin θ = opposite / hypotenus

Sin 40° = 225 / hypotenus

Cross multiply

Hypotenus × 0.6427876 = 225

Divide both sides by 0.6427876 to isolate the hypotenus

Hypotenus = 225 / 0.6427876

Hypotenus = 350.03786 cm

Therefore, the length of the ramp which is the hypotenus is approximately 350 cm
