Answer:
Option D [
] in the list of possible answers
Step-by-step explanation:
For this problem you are supposed to use a calculator that allows you to do an exponential regression. There are many tools that can help you with that, depending on what your instructors has assigned for your class.
I am showing you the results of a graphing tool I use, and which after entering the x-values and the y-values in independent "List" forms, when I request the exponential regression to fit the data, I get what you can see in the attached image.
Notice that the exponential of best fit with my calculator comes in the form:
with optimized parameters:
Notice as well that since:
the exponential best fit can also be written:
and this expression is very close to the last option shown in your list of possible answers
Answer:
A
Step-by-step explanation:
Sorry you got it wrong but i was confused since y axis is up and down but they ment straight across
Answer:
Step-by-step explanation:
see the attached figure with letters to better understand the problem
we know that
In the right triangle ABD
In the right triangle BCD
remember that
m< BAD=m<CBD
therefore
equate the equations
In general, you're calculating the magnitude of average velocity. In fact, speed is a vector, and as such it also has a direction and orientation.
So, if you compute the average speed, you're assuming that you went directly from point A to point B, which is basically never the case.
If, instead, you actually moved on a straight line from point A to point B, then the two quantities are the same.
I didn't get to finishing the problem (I just got distracted from my exams lol) but here are the equations for each of the people, if it helps.
S=-6L-2n+198
L=-.25n+33
N=-3.2727L+118.8
Sorry I couldn't be of more help!
