Jen’s goal is to run a total of 22 miles in five days. The table below shows her log for the number of miles she ran on Monday,
Ronch [10]

Answer: 5.875 miles run on Friday to reach her goal by Jen

Step-by-step explanation:

Since we have given that

Part of distance covered on Monday by Jen is given by

4\frac{3}{4}=\frac{19}{4}

Part of distance covered on Tuesday by Jen is given by

5\frac{1}{8}\\\\=\frac{41}{8}

Part of distance covered on Wednesday by Jen is given by

0

Part of distance covered on Thursday by Jen is given by

6\frac{1}{4}\\\\=\frac{25}{4}

Total part of distance covered in these four days by Jen is given by

\frac{19}{4}+\frac{41}{8}+0+\frac{25}{4}\\\\=\frac{38+41+0+50}{8}\\\\=\frac{129}{8}=16.125\ miles

Remaining part of distance will be covered on Friday to reach her goal which is given by

22-16.125=5.875\ miles

Hence, 5.875 miles run on Friday to reach her goal by Jen.

This is the "commutative property of addition."  The order in which you add numbers together doesn't matter, and doesn't change your final results.

A city starts with a population of 500,000 people in 2007. Its population declines according to the equation
hjlf

Answer: After 7 years the population will be one-half the initial amount.

Step-by-step explanation:

Given: Initial population = 500,000

The population declines according to the equation:

P(t) = 500,000e^{ -0.099t}, where P is the population in t years later.

One-half the initial amount = 0.5 x 500,000

= 250,000

Put P(t)=250,000, we get

250000=500000e^{-0.099t}\\\\\Rightarrow\ \frac{500000e^{-0.099t}}{500000}=\frac{250000}{500000}\\\\\Rightarrow\ e^{-0.099t}=\frac12\\\\\Rightarrow\ -0.099t=\ln \left(\frac{1}{2}\right)\\\\\Rightarrow\ t=\frac{1000\ln \left(2\right)}{99}=\frac{1000(0.69314)}{99}\\\\\Rightarrow\ t=7.00148\approx7

Hence, After 7 years the population will be one-half the initial amount.
