Question

Joaquin has a bacteria colony of 1,000 that is doubling every hour. Which equation should he use to estimate the population for a given hour (x) ?

Answers:
A. Y=1000+2x
B. Y=1000(2)^x
C. Y=2(1000)^x
D. Y=1000(2x)

Answer 1

The answer is D because A is addition. B is multiplication but the x is read as a exponent. C is a reflection of B. So S is the answer because the key word every gives the idea of multiplication. Plus x=hour so if 1000 doubles every hour then it would go 1000(2x)
2000(2x)
4000(2x)
And so on I hope I helped
