Submit Question
Answers
Compute the first few derivatives to reveal a pattern:
f(x) = x sin(x)
f '(x) = x cos(x) + sin(x)
f ''(x) = (-x sin(x) + cos(x)) + cos(x) = -x sin(x) + 2 cos(x)
f '''(x) = (-x cos(x) - sin(x)) - 2 sin(x) = -x cos(x) - 3 sin(x)
f ''''(x) = (x sin(x) - cos(x)) - 3 cos(x)) = x sin(x) - 4 cos(x)
f ⁽⁵⁾(x) = (x cos(x) + sin(x)) + 4 sin(x) = x cos(x) + 5 sin(x)
f ⁽⁶⁾(x) = (-x sin(x) + cos(x)) + 5 cos(x) = -x sin(x) + 6 cos(x)
f ⁽⁷⁾(x) = (-x cos(x) - sin(x)) - 6 sin(x) = -x cos(x) - 7 sin(x)
f ⁽⁸⁾(x) = (x sin(x) - cos(x)) - 7 cos(x) = x sin(x) - 8 cos(x)
and so on.
The pattern should be clear: for some integer k,
• if n = 4k, then f ⁽ⁿ ⁾(x) = x sin(x) - n cos(x)
• if n = 4k + 1, then f ⁽ⁿ ⁾(x) = x cos(x) + n sin(x)
• if n = 4k + 2, then f ⁽ⁿ ⁾(x) = -x sin(x) + n cos(x)
• if n = 4k + 3, then f ⁽ⁿ ⁾(x) = -x cos(x) - n cos(x)
80 is a multiple of 4, so the 80th derivative falls in the first category. Then
f ⁽⁸⁰⁾(x) = x sin(x) - 80 cos(x)

Answers
Answer:
[tex]Total = 2.35n[/tex]
Step-by-step explanation:
Given
Monday = n
Tuesday = 90% of Monday
Wednesday = 50% of Tuesday
Required
Determine the total miles
We have:
Tuesday = 90% of Monday
Substitute n for Monday
Tuesday = 90% of n
[tex]Tuesday = 90\% * n[/tex]
Express percentage to decimal
[tex]Tuesday = 0.90 * n[/tex]
[tex]Tuesday = 0.90n[/tex]
We also have that:
Wednesday = 50% of Tuesday
Wednesday = 50% * Tuesday
Substitute 0.90n for Tuesday
[tex]Wednesday = 50\% * 0.90n[/tex]
Express percentage to decimal
[tex]Wednesday = 0.50 * 0.90n[/tex]
[tex]Wednesday = 0.45n[/tex]
The total number of miles is:
[tex]Total = Monday + Tuesday + Wednesday[/tex]
[tex]Total = n + 0.90n + 0.45n[/tex]
[tex]Total = 2.35n[/tex]

Answer:

Step-by-step explanation:
If a triangles' degrees are 45° 45° and 90°; you have what is called a Special Right Triangle. This is simple and easy to understand with the right equations and setup. Draw yourself a right triangle with side a & b being the same length, label your triangle and angles. I am guessing with the limited question that your side x is either side a or b on your triangle, which means they are both the same length. But if you have a measurement for side c, your hypotenuse, the equation would be: c
