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
Cos (π/2 - x) = sin x = 3/5
tan x = sin x / cos x = 3/5 / 4/5 = 3/4
csc x = 1/sin x = 1 / 3/5 = 5/3
sec x = 1/cos x = 1 / 4/5 = 5/4
cot x = 1/tan x = 1 / 3/4 = 4/3.

Step-by-step explanation:
1.(70-24)/2 = 23
2. 295 x 8.95 =2640.25 - 400 = 2240.25 ~ $2000
3. 21hoursx48 weeks x 2years = 2016 hours ~ 2000
C. a-3x=0
Equations are like a balance scale. There needs to be an “=“
20 tulips. 2/3=20/30 when you multiply both the denominator and numerator by 10.
