Answer:
right angle triangle
Step-by-step explanation:
because the number given below is less then 90°
The linear function that can be used to determine the height, H, of the plane after m minutes is given by:
H(m) = 8000 - 500m
<h3>What is a linear function?</h3>
A linear function is modeled by:
In which:
- m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
- b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value.
In this problem:
- The plane is descending from an altitude of 8,000 feet, hence the y-intercept is b = 8000.
- The plane descends at a constant rate of 500 feet per minute, hence the slope is of m = -500.
Thus, the equation is:
H(m) = 8000 - 500m.

$79.20 is the correct answer.
To solve the two sets of equations simultaneously, subtract one equation from the other to obtain
3x^5 + 2x^2 - 10x + 4 - (4x^4 + 6x^3 - 11) = 0
3x^5 - 4x^4 - 6x^3 + 2x^2 - 10x - 7 = 0
This is a polynomial of degree 5 to be solved for zeros.
A graphing calculator will yield 3 real zeros (verifiable by Descartes Rule of Signs).
