Answer:
Approximately 3 grams left.
Step-by-step explanation:
We will utilize the standard form of an exponential function, given by:
In the case of half-life, our rate <em>r</em> will be 1/2. This is because 1/2 or 50% will be left after <em>t </em>half-lives.
Our initial amount <em>a </em>is 185 grams.
So, by substitution, we have:
Where <em>f(t)</em> denotes the amount of grams left after <em>t</em> half-lives.
We want to find the amount left after 6 half-lives. Therefore, <em>t </em>= 6. Then using our function, we acquire:
Evaluate:
So, after six half-lives, there will be approximately 3 grams left.
Answer:
0.7
Step-by-step explanation:
We have been given graph of circle V with radius 14 feet. We are asked to find the area of the circle V.
We will use area of circle formula to solve our given problem.
, where r represents radius of circle.
Upon substituting 
in above formula, we will get:
Therefore, the area of the circle V is 
square feet and option 'c' is the correct choice.
Answer:
$125/month
Step-by-step explanation:
<em>equation we got:</em>
7500 = 36x + 3000
<em>subtract</em><em> </em><em>3</em><em>0</em><em>0</em><em>0</em><em> </em><em>from</em><em> </em><em>both</em><em> </em><em>sides</em>
4500 = 36x
<em>divide</em><em> </em><em>both</em><em> </em><em>sides</em><em> </em><em>by</em><em> </em><em>3</em><em>6</em><em> </em><em>to</em><em> </em><em>get</em><em> </em><em>x</em><em> </em><em>by</em><em> </em><em>itself</em>
125 = x
x = 125
<em> </em><em>so</em><em> </em><em>rayyan</em><em> </em><em>paid</em><em> </em><em>$</em><em>1</em><em>2</em><em>5</em><em> </em><em>per</em><em> </em><em>month</em>
