Answer:
The answer is B.500
Step-by-step explanation:
The original equation containing unknown variables would be 500(t) (with "t" representing the number of days)
So if you fill the variable in with a 2, that means it's been 2 days with the increase of 500 bacteria each day.
That means the initial number of bacteria must be 500.
If it's been 2 days and you want to determine the bacteria number, then multiply 500 by 2 and you get yourself 1000 bacteria.

Cos9x - cos5x = -2sin2x.sin7x
sin17x - sin3x = 2sin7x.cos10x
so f(x) =

Step-by-step explanation:
10x3=30
Remember, (a/b)/(c/d)=(a/b)(d/c)=(ad)/(bc)
so
walls per gallon
4/5 wall per 5/8 gallon
(4/5)/(5/8)
(4/5)(8/5)
32/25
1.28
the unit rate is 1.28 walls per gallon
