ElenaW [278]

The graph is missing, so i have attached it.

Answer:

Step-by-step explanation:

From the attached graph, we can see that on the y-axis, denotes the level of ibuprofen in the patient’s bloodstream while the x-axis denotes the amount of hours after the ibuprofen was taken.

Now, looking at the graph, we can see that the curve goes up from a time of 0 hours which corresponds to 0 mg of ibuprofen to a time of 2 hours which corresponds to 400 mg of ibuprofen.

Suppose you loan $320 to a friend and charge them 11% annual interest. If they don't pay any back, how many years will it take f
AnnZ [28]

Step-by-step explanation:

For them to owe you a total of$2000 then an interest of $2000-320=$1680 must have accrued over the time <em>T</em>

<em>T</em><em>=</em><em>$</em><em>1</em><em>6</em><em>8</em><em>0</em><em>×</em><em>1</em><em>0</em><em>0</em><em>/</em><em>3</em><em>2</em><em>0</em><em>×</em><em>1</em><em>1</em>

<em>T</em><em>=</em><em>4</em><em>7</em><em>.</em><em>7</em><em>2</em><em>7</em><em>2</em><em>.</em><em>.</em><em>.</em><em>≈</em><em>4</em><em>7</em><em>.</em><em>7</em><em>3</em><em> </em><em>to</em><em> </em><em>the</em><em> </em><em>nearest</em><em> </em><em>hundredth</em>

Proof,

Interest after 47.7262...years which is converted to 525/11 years

=($320×11×525/11)/100

=$1680

therefore total amount which will be owed at that time =principal+interest accrued

=$320+1680=$2000
