Answer:

0.808 kilometers

Step-by-step explanation:

Given: On Saturday Keisha ran 3.218 \text{kilometer}. on Sunday she ran  2.41 \text{kilometer}.

To Find: How much further did she run on Saturday than on Sunday.

Solution:

Kilometers run by keisha on saturday =3.218 \text{kilometer}

Kilometers run by keisha on sunday   =2.41 \text{kilometer}

Now,

kilometers covered further by keisha on saturday than sunday

                    =\text{kilometers covered on Saturday}-\text{kilometers covered on Sunday}

putting values,

                    3.218-2.41

                    0.808 \text{kilometer}

keisha run 0.808 \text{kilometer} further on saturday than on sunday.

The mileage is 27.6 mi/gal
Miles driven = 552.4 mi

Calculate gallons used.
gallons = \frac{552.4 \, mi}{27.6 \, mi/gal} = 20.015 \, gal

Answer: 20.015 gallons  (approximately 20 gallons)

Natalie has $5000 and decides to put her money in the bank in an account that has a 10% interest rate that is compounded continu
kakasveta [241]

Step-by-step explanation:

  • Natalie has $5000
  • She decides to put her money in the bank in an account that has a 10% interest rate that is compounded continuously.

Part a) What type of exponential model is Natalie’s situation?

Answer:

As Natalie's situation implies

  • continuous compounding. So, instead of computing interest on a finite number of time periods, for instance monthly or yearly, continuous compounding computes interest assuming constant compounding over an infinite number of periods.

So, it requires the more generalized version of the principal calculation formula such as:

P\left(t\right)=P_0\times \left[1+\left(i\:/\:n\right)\right]^{\left(n\:\times \:\:t\right)}

or

P\left(t\right)=P_0\times \left[1+\left(\frac{i}{n}\:\right)\right]^{\left(n\:\times \:\:t\right)}

Here,

i = interest rate

= number of compounding periods

t = time period in years

Part b) Write the model equation for Natalie’s situation?

For continuous compounding the number of compounding periods, n, becomes infinitely large.

Therefore, the formula as we discussed above would become:

                                        P\left(t\right)=P_0\times e^{\left(i\:\times \:t\right)}

Part c) How much money will Natalie have after 2 years?

Using the formula

                            P\left(t\right)=P_0\times e^{\left(i\:\times \:t\right)}

$₂ =\:6107.02 $

So, Natalie will have \:6107.02 $ after 2 years.

Part d) How much money will Natalie have after 2 years?

Using the formula

                            P\left(t\right)=P_0\times e^{\left(i\:\times \:t\right)}

$₁₀ =13.597.50 $

So, Natalie will have 13.597.50 $ after 10 years.
