Take derivitive
remember chain rule
dy/dx=1/(x² ? 7x+1) times (2x ? 7)
dy/dx=(2x ? 7)/(x² ? 7x+1)
inputting x=7
the slope at x=7 is (14 ? 7)/(49 ? 49+1)=(14 ? 7)/(49 ? 50)
the slope is (14 ? 7)/(49 ? 50)
use point slope form
y-0=(14 ? 7)/(49 ? 50)(x-7)
y=(14 ? 7)/(49 ? 50)(x-7)
I'm going to take a wild guess that the ? means minus because you were able to type a plus sign
in that case, it would be
y=-2(x-7)
Qualitative is something that describe like the different colors of something.
And Quantitative are numbers are quantity like the name says.
So I would say that distance is quantitative.
I hope this helps :D
Answer:
90 minutes
Step-by-step explanation:
40/1 =60/x
We would divide 60 by 40 and I got 1.5 which is one hour and a half(30).
One hour=60 minutes
A half=30minutes
60min+30min=90min
90 is the answer.
