Answer:
27 hours
Step-by-step explanation:
216/8=27
The rate of change of the plane's altitude is 2250 feet per minute.
<h3>How to calculate the rate?</h3>
The rate of change of the plane's altitude will be:
= (35000 - 17000)/8
= 18000/8
= 2250 feet per minute.
When graphing the descent of the plane, the starting value for its altitude be 35000 feet.
The linear function will be:
y = mx + b
35000 = 2250x + b
35000 = 2250(0) + b
b = 35000
y = -2250x + 35000
The information given in this problem that did not need to write an equation for the descent is the initial details about how long that the plane travelled.

Answer:
101.6 centimeters
Step-by-step explanation:
l
The factor of f(x) is (x-(4-13i))
If a polynomial function f(x) has roots 4 – 13i and 5
One of the complex roots is 4-13i
If we have one complex root then there should be one more complex root.
<h3>What is the complex root?</h3>
complex roots come in pairs like (a+ib) and (a-ib)
so another complex root for 4-13i is 4+13i
If 'a' is a root then the factor is (x-a)
4+13i is a root
So the factor is (x-(4-13i))
