1. I suppose the ODE is supposed to be
Solving for gives
which is undefined when . The interval of validity depends on what your initial value is. In this case, it's , so the largest interval on which a solution can exist is .
2. Separating the variables gives
Integrate both sides. On the left, we have
where we substituted - or - and - or .
On the right, we have
So
I'll leave the solution in this form for now to make solving for easier. Given that , we get
and so our solution is
Answer:
multiple triangles
Step-by-step explanation:
add the numbers up it adds to 180 which is the sum of a triangle and could create other triangles
8x+9y equals 10 is a variation in fact
The correct answer is: [C]: " 5√3 " .

Explanation:
_________________________________________________
In a "30-60-90" triangle:
The side opposite from the "30° angle" is "x" ;
The side opposite from the "60° angle is: "x√3" ;
and the "hypotenuse" is: "2x" ;
_________________________________________________
So, from the "image attached":
The side opposite from the "60° angle is: "x√3" ; which equals: " 15 " (given) ;
So, x√3 = 15 ;
Divide each side by "√3" ; to isolate "x" on one side of the equation ;
& to solve for "x" ;
(x√3) / √3 = 15 / √3 ;
x = 15 / √3 ;
→ Multiply the entire equation by "√3/√3" (which equals "1"); to get ride oif the "square root" in the "denominator" ;
→ " 15 / √3 = (15 *√3) / (√3 * √3) " ;
= (15√3) / 3 ;
= <span>5√3 ;</span> which is: Answer choice: [C]: " 5√3 " .
