54, 36, 24 are the 1st 3 element of a geometric progression with 2/3 as a common ratio: PROOF:
the 1st term is 54, (a₁= 54) the 2nd term a₂ = 24, then
(a₂ = a₁.r) or 36 = 54.r → r= 36/54 = 2/3. Same logique for the 3rd term.
So 2/3 is common ratio. We know that :U(n) = a.(r)ⁿ⁻¹. Then if a =54 and r = x (given by the problem), then f(x) = 54.xⁿ⁻¹
n, being the rank of any element of this geometric progression
Answer: x = 69
Step-by-step explanation:
Answer:
Yes it is proportional because if the line kept going, it would pass through the origin. Fora line to be proportional, it must pass through the origin.
Origin= (0,0)

Exchanging x and y and isolating y, it is found that the inverse function is:
The function given is:
To find the <em>inverse function</em>, we exchange x and y and isolate y, hence:
Hence, the inverse function is:
