Answer:
f^-1 represents the number of hours the bacteria developed
Step-by-step explanation:
To find inverse of a function , replace f(t) with y
replace t with y and y with x
solve for y
divide both sides by 100
take ln on both sides
divide both sides by ln
multiply by 3 on both sides
Replace x with t and y with f^-1
f^-1 represents the number of hours the bacteria developed
Refer to the graph shown below. It confirms that points A, B and P are
collinear.
Calculate the length of AP (as a).
a = √[(6 - 2)² + (11 - 3)²]
= 8.9443
Calculate the length of BP (as b).
b = √[(8 - 6)² + (15 - 11)²]
= 4.4721
Calculate ratio a/b.
a/b = 8.9443/4.4721 = 2
Therefore P partitions AB in a 2:1 ratio so that AP = 2*BP.
Answer: 2:1 ratio.
