Answer:

a) mJI = m∠JKI = 125°, same measure as central angle
b) mIJH = 360° - (180° - 125°) = 305°, same as central angle ∠IJH
c) m∠IKH = 180° - 125° = 55°, supplementary with ∠JKI

4 units because the y-intercept is how you figure out the difference. You take the y-intercept, find the absolute value of it, and you found the distance of the line! This is of course considering the lines are parallel, meaning the slope is the same.

Answer:

the one on the top right

Step-by-step explanation:

because the difference is the same between them so it has a fixed slope

3(x+5) +2x=10x-5(x+1)

posledela

Answer:

no solution

Step-by-step explanation:

3(x+5) +2x=10x-5(x+1)

Distribute

3x+15 +2x = 10x-5x-5

Combine like terms

5x+15 = 5x -5

Subtract 5x from each side

5x-5x+15 = 5x-5x-5

15 = -5

This is never true so there is no solution

Show that ( 2xy4 + 1/ (x + y2) ) dx + ( 4x2 y3 + 2y/ (x + y2) ) dy = 0 is exact, and find the solution. Find c if y(1) = 2.

$\dfrac{\partial\left(2xy^4+\frac1{x+y^2}\right)}{\partial y}=8xy^3-\dfrac{2y}{(x+y^2)^2}$

$\dfrac{\partial\left(4x^2y^3+\frac{2y}{x+y^2}\right)}{\partial x}=8xy^3-\dfrac{2y}{(x+y^2)^2}$

so the ODE is indeed exact and there is a solution of the form $F(x,y)=C$ . We have

$\dfrac{\partial F}{\partial x}=2xy^4+\dfrac1{x+y^2}\implies F(x,y)=x^2y^4+\ln(x+y^2)+f(y)$

$\dfrac{\partial F}{\partial y}=4x^2y^3+\dfrac{2y}{x+y^2}=4x^2y^3+\dfrac{2y}{x+y^2}+f'(y)$

$f'(y)=0\implies f(y)=C$

$\implies F(x,y)=x^2y^3+\ln(x+y^2)=C$

With $y(1)=2$ , we have

$8+\ln9=C$

so

$\boxed{x^2y^3+\ln(x+y^2)=8+\ln9}$

Please help me! I need an answer as soon as possible!

Answer:

It should just be the radius

Step-by-step explanation:

The radius is half the diameter of the circle and all you’re doing is taking the radius multiple times
