58.(A) (5pts)A certain type of bacteria, given favorable growth medium, quadruples in population every 6 hours. Given that there
Jet001 [13]

Answer:

157286400 bacteria

Step-by-step explanation:

We are given the following in the question:

The bacteria increases 4 times every 6 hours.

Initially there are 150 bacteria.

Thus, we can write the function for number of bacteria after x hours,

f(x) = 150(4)^{\frac{x}{6}}

We have to find the number of bacteria in 2.5 days.

1 day = 24 hours

Thus,

2.5\text{ days} = 24\times 2.5 = 60\text{ hours}

Putting x = 60 in the above equation, we get,

f(60) = 150(4)^{\frac{60}{6}} = 150(4)^{10} = 157286400

Thus, there will be 157286400 bacteria in two and a half days.

Leon charged $75 at an interest rate of 12.5% how much will Leon have to pay after one month if he makes no payments
OlgaM077 [116]

So basically, let's look at the given. In the problem, Leon is charged a fee of 75. The interest rate would be 12.5 % if he doesn't pay his due amount. So in order to get the total amount that he has to pay if he doesn't pay on time, you just need to multiply 75 with 12.5% or simply 0.125. If you do this, you will get 9.375. After that, you add 9.375 to the principal amount which is 75 and you will get 84.375. So Leon has to now pay a total of 84.375.

I hope this HELP! :)
