Answer:
<u>Yes. I agree with his claim because the equation relating the miles left to walk and the number of miles left to walk is :</u> 
Step-by-step explanation:
Given :
- <em>It's a 21 - mile walkathon</em>
- <em>The rate at which he is moving is 3 miles per hour.</em>
Let the number of miles walked be 
;
∴,
The number of miles '
' left to walk will be : 
<em>Thus the time '
' for which he walked :</em>
:
∴
From these equations , we get :
Thus , when we compare this with 
,
<u>Thus this is an equation of a Line with slope -3.</u>
Answer:
A plasmid is a small, circular, double-stranded DNA molecule that is distinct from a cell's chromosomal DNA. ... Researchers can insert DNA fragments or genes into a plasmid vector, creating a so-called recombinant plasmid. This plasmid can be introduced into a bacterium by way of the process called transformation.

The veretx is normally the minimum value
hack:
for f(x)=ax²+bx+c
the x value of the vertex is -b/2a
so
f(x)=1x²-16x+71
x value is -(-16)/(2*1)=16/2=8
find f(8) to find y value of vertex
f(8)=8²-16(8)+71
f(8)=64-128+71
f(8)=7
the vertex is (8,7)
the minimum value is 7
