The linear function g which has a rate of change of -16 and initial value 600 is; g = -16x + 600.
<h3>What is the linear function which is as described?</h3>
It follows from the task content that the linear expression which is as described by the given verbal description is to be determined.
Since the standard slope-intercept form of a linear function is as given; f(x) = ax + b.
Where, a = slope (rate of change) and b = y-intercept (initial value).
Therefore, the required linear function which is as described is;
g = -16x + 600

Answer: 228 feet squared
How: To get the area of the entire field, multiply 25•36 to get 900. To find length of the area inside the path, you have to subtract 2 feet from both sides of 25, which is also 4 feet, to get 25-4=21. To find the width of the area inside the path, you have to subtract 2 feet from both sides of 36, which is also 4 feet, to get 36-4=32. You multiply 21•32 to get 672, which is the area of the field inside of the path. To find the area of the path, you subtract the total area of the field and the path together, which is 900, by 672 to get 228 feet squared.
Answer:
<em>f</em> has no critical points.
Step-by-step explanation:
We are given:

A function has critical points whenever its derivative equals 0 or is undefined.
Differentiate the function:

Since this will never be undefined, solve for its zeros:

Hence:

Recall that the value of sine is always between -1 and 1.
Thus, no real solutions exist.
Therefore, <em>f</em> has no critical points.
