The following graph represents a retirement savings account after the owner of the account begins withdrawing 5% each year.

Dmitry [639]

Answer:

Options 2 and 5 are true.

Step-by-step explanation:

We are given that,

The graph represents the amount in the savings account after the owner withdraws the money each year.

According to the options, we have,

1. As time increases, the amount of money in the savings account is decreasing. So, the function is an example of exponential decay.

2. Also, the initial amount of money in the account is 500,000 dollars.

3. After 10 years, the amount in the account is less than 300,000 dollars.

4. Now, the amount withdrawn by the owner is decreasing exponentially and so cannot be same each year.

5. Further, the y-intercept is the point when y= 500,000 dollars, which is the amount of money in the account when the owner started withdrawing.

Hence, we get that,

Options 2 and 5 are true.

Suppose that the number of bacteria in a certain population increases according to an exponential growth model. A sample of 2600

melisa1 [442]

Answer: There is 3.994% continuous growth rate per hour.

Step-by-step explanation:

Since we have given that

Initial bacteria = 2600

After two and a half hours,

Number of bacteria = 2873

We need to find the continuous growth rate per hour.

As we know the equation for continuous growth rate per hour.

$y=y_0e^{rt}\\\\2873=2600e^{2.5r}\\\\\dfrac{2873}{2600}=e^{2.5r}\\\\1.105=e^{2.5r}\\\\\text{Taking log on both the sides}\\\\\ln 1.105=2.5r\\\\0.0998=2.5r\\\\r=\dfac{0.0998}{2.5}\\\\r=0.0399\times 100\\\\r=3.994\%$

Hence, there is 3.994% continuous growth rate per hour.
