Hi there!
To find our answer we need to collect the terms of the expression.
The coefficient (which is the number just before the variable) of the simplified expression is 13.

The coefficient (which is the number just before the variable) of the simplified expression is 13.
Answer:
1
Step-by-step explanation:
So for this type of problem we use the formula with each variable (besides m which is slope) representing a different coordinate. (e.g. -3 could be
in this case.) First, let's define which is which:
(3,2):
(-2,-3):
Now we need to replace the variables with their known values:
Next, let's do the subtraction to simplify:
And we can complete the division (all fractions are division!) to simplify even further:
Therefore, the slope of the line passing through the points (3,2) and (-2,-3) is 1.
Answer:
f'(N) = a(k² - N²)/(k² + N²)
The function increases in the interval
(-k < N < k)
And the function decreases everywhere else; the intervals given as
(-∞ < N < -k) and (k < N < ∞)
Step-by-step explanation:
f(N)=aN/(k²+N²)
The derivative of this function is obrained using the quotient rule.
Then to determine the intervals where the function is increasinumber and decreasing,
The function increases in intervals where f'(N) > 0
and the function decreases in intervals where f'(N) < 0.
This inequality is evaluated and the solution obtained.
The solution is presented in the attached image.
Hope this Helps!!!
