as you can see, the bigger triangles given sides are 4 times bigger than the little triangle's sides. when you divide 52 (the side being compared to x) you get 13.
the answer is f(x)=2x-1
i think the answer is 28ft 12in. sorry if im wrong, but let me know if i am
ignacio can make 5 clockwise rotations.
given that the ignacio's legs are already at a height of 49.3cm and each rotation of the chair knob raises his legs another 4.8cm, we can set up an inequality to determine the number of rotations ignacio could make without his legs touching the desk, which is at a height of 74.5cm:
4.8r + 49.3 < 74.5 where 'r' is equal to the number of rotations
the sum of the ignacio's original leg height plus the amount of height increased from the rotations of the know must be less than 74.5 in order for his legs not to touch. now, solve for 'r':
subtract 49.3 from both sides: 4.8r + 49.3 - 49.3 < 74.5 - 49.3 or 4.8r < 25.2
divide 4.8 from both sides: 4.8r/4.8 < 25.2/4.8 or r < 5.25
since the number of rotations must be less than 5.25, he can make 5 complete rotations.
