Step-by-step explanation:
Let
be the angle between the two sides and x be the length of the third side. By cosine rule,
We differentiate x with respect to
by applying chain rule.
Rate of change of
is 2
Rate of change of x is
At 60°,
Ответ:
The average rate of change cover the given interval is -6
Step-by-step explanation:
The average rate of change of a function over a range can be calculated by;
f(b) - f(a)/b-a
f(b) and f(a) refers to the respective y values of the x values a and b
Since we have a and b, we can get f(a) and f(b) from the plot
From the graph, since a = 0, f(a) is the y-intercept = 6
b = 1
f(b) = 0
So we have the slope as
= (0-6)/(1-0) = -6/1 = -6
