Answer:
The inverse function of f(x) is ... f⁻¹(x) = log (x/9.16)/log (1.0054)
Step-by-step explanation:
Starting equation... f(x) = 9.16(1.0054)ˣ
Visually rewritten... y = 9.16(1.0054)ˣ
Flipping x and y... x = 9.16(1.0054)ʸ
Isolating (1.0054)ʸ... x/9.16 = (1.0054)ʸ
Taking the log of both sides... log (x/9.16) = y log (1.0054)
Isolating y... log (x/9.16)/log (1.0054) = y
Solution... y = log (x/9.16)/log (1.0054)
The y-coordinates are the same, so the length of this horizontal line segment is the difference between the x-coordinates.
Length = 7 - (-5) = 12 units
7(72) + 0.10(2574) = 504 + 257.40 = 761.40 <== this is how much she will earn. Your gonna have to pick the answer choice that is the closest since no answer choices were given.
<span>If she puts the same amount of confetti in each 5 bags - means that she divides all amount into 5 bags.
So,
4.75 : 5 = 0.95
Answer: each bag should weigh 0.95 pounds.</span>
