Include both real and complex singular points. If there are no singular points in a certain category, enter NONE.)(x2 − 4)2y'' + (x + 2)y' + 7y = 0
Answers
Answer:
Step-by-step explanation:
Given that:
The differential equation; [tex](x^2-4)^2y'' + (x + 2)y' + 7y = 0[/tex]
The above equation can be better expressed as:
[tex]y'' + \dfrac{(x+2)}{(x^2-4)^2} \ y'+ \dfrac{7}{(x^2- 4)^2} \ y=0[/tex]
The pattern of the normalized differential equation can be represented as:
y'' + p(x)y' + q(x) y = 0
This implies that:
[tex]p(x) = \dfrac{(x+2)}{(x^2-4)^2} \[/tex]
[tex]p(x) = \dfrac{(x+2)}{(x+2)^2 (x-2)^2} \[/tex]
[tex]p(x) = \dfrac{1}{(x+2)(x-2)^2}[/tex]
Also;
[tex]q(x) = \dfrac{7}{(x^2-4)^2}[/tex]
[tex]q(x) = \dfrac{7}{(x+2)^2(x-2)^2}[/tex]
From p(x) and q(x); we will realize that the zeroes of (x+2)(x-2)² = ±2
When x = - 2
[tex]\lim \limits_{x \to-2} (x+ 2) p(x) = \lim \limits_{x \to2} (x+ 2) \dfrac{1}{(x+2)(x-2)^2}[/tex]
[tex]\implies \lim \limits_{x \to2} \dfrac{1}{(x-2)^2}[/tex]
[tex]\implies \dfrac{1}{16}[/tex]
[tex]\lim \limits_{x \to-2} (x+ 2)^2 q(x) = \lim \limits_{x \to2} (x+ 2)^2 \dfrac{7}{(x+2)^2(x-2)^2}[/tex]
[tex]\implies \lim \limits_{x \to2} \dfrac{7}{(x-2)^2}[/tex]
[tex]\implies \dfrac{7}{16}[/tex]
Hence, one (1) of them is non-analytical at x = 2.
Thus, x = 2 is an irregular singular point.

Marco’s football team gained 13 yards on their first play, but lost 7 yards on the second. How many yards did they gain between the two plays?
Answers
Answer:
6 yards were gained between the two plays.
Step-by-step explanation:
13 minus 7 is 6.
Losing a value is decreasing, so you would use a negative sign.
Subtract the partial value lost from the total.
You get 6.
Answer:
6 yards. Marco and his football to got 6 yards.

Answers
Answer:
9.2
Step-by-step explanation:
So the 14 can be divided equally on both sides by the fact that the line cutting it at right angle bisects it.
Thus having 6 and 7 as the two shorter sides of a right angled triangle will help us get the radius( hypotenuse in this case) using the square root of the sum of the squares of both six and 7, the Pythagoras theory.
this leads to 9.2 as our answer

I need help finding the equations of the line in slope intercept form
Answers
Slope intercept form is written as y=mx+b, where m is the slope and b is the y intercept.
To find the slope, find the rise (vertical) over the run (horizontal). To get from one point to another, the line goes up by two and across by one. The slope would be 2/1 which simplifies to 2.
To find the intercept, find where the line crosses the y intercept (vertical axis). It crosses at 2.
