Answer:
5715
Step-by-step explanation:
So this is just a guess but-
if one balloon can lift someone o the weight of 14 grams, then just divide 80010 by 14-
80010/14=5715
Answer: <u>This is only a guess! </u> 5715
Answer:
f⁻¹(1/5) = 2
Explanation:
If f(x) = (2x -3)/5
To find inverse of f(x), make x the subject.
![f(x) = \dfrac{2x - 3}{5}](https://tex.z-dn.net/?f=f%28x%29%20%3D%20%5Cdfrac%7B2x%20-%203%7D%7B5%7D)
![5 f(x) = 2x - 3](https://tex.z-dn.net/?f=5%20f%28x%29%20%3D%202x%20-%203)
![2x = 5 f(x) + 3](https://tex.z-dn.net/?f=2x%20%3D%205%20f%28x%29%20%2B%203)
![x = \dfrac{5 f(x) + 3}{2}](https://tex.z-dn.net/?f=x%20%3D%20%5Cdfrac%7B5%20f%28x%29%20%2B%203%7D%7B2%7D)
Then,
![f^{-1}(x) = \dfrac{5x+3}{2}](https://tex.z-dn.net/?f=f%5E%7B-1%7D%28x%29%20%3D%20%5Cdfrac%7B5x%2B3%7D%7B2%7D)
To find f⁻¹(1/5), simplify insert [x = 1/5 or 0.2]
![f^{-1}(0.2) = \dfrac{5(0.2)+3}{2}](https://tex.z-dn.net/?f=f%5E%7B-1%7D%280.2%29%20%3D%20%5Cdfrac%7B5%280.2%29%2B3%7D%7B2%7D)
which yields
![f^{-1}(0.2) = 2](https://tex.z-dn.net/?f=f%5E%7B-1%7D%280.2%29%20%3D%202)
I think it’s perpendicular, I tried to do a quick drawing, sorry if it’s not perfect ☹️
The answer would be -pd-pz = -2z+59. Unless the variable(s) is revealed.
… z =w …angle v x w = angle z x y
It follows AAA SIMILARITY Relation
