Answer:

f(x) = 1500(2.15)^x

Step-by-step explanation:

Let the function that represents the population of bacteria after x hours is,

f(x)=ab^x

For x = 0, f(x) = 1500,

1500=a(1+r)^0

1500=a

Now, the population increases at a rate of 115% each hour,

So, the population after 1 hour = (100+115)% of 1500 = 215% of 1500 = 3225,

That is, for x = 1, f(x) = 3225,

3225 =ab

3225=1500(b)

\implies b =2.15

Hence, the function that represents the given scenario is,

f(x)=1500(2.15)^x

Answer:

Step-by-step explanation:

A colony contains 1500 bacteria. The population increases at a rate of 115% each hour. If x represents the number of hours elapsed, which function represents the scenario?

f(x) = 1500(1.15)x  

f(x) = 1500(115)x

f(x) = 1500(2.15)x

f(x) = 1500(215)x

The answer to this problem is a f(x) = 1500(2.15)x

How do you solve [x^2(2x+3)]^3 ?
Bond [772]

Answer:

here's the steps

Step-by-step explanation:

first of the numbers inside the [ ] is always positive.Now since the 3 is outside the [ ] you use it like a tool and don't change it, so nothing happen to it.since ^3 is missing a base (variable, cannot remember exact name) but is not missing ^3, which make them alike enough to multiply because 3 is outside of () nut the ^3 will stay the same (don't know why but that's how math works)
