The distance between the coordinates in meters is 138.92m

Using the distance formula to calculate the distance between the coordinates as shown:

$D = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2} \\$

Given the coordinate points C(-5, 8) and V (7, 1)

Substitute the given coordinates into the formula

$D = \sqrt{(7+5)^2+(1-8)^2} \\D = \sqrt{(12)^2+(-7)^2} \\D = \sqrt{144+49} \\D = \sqrt{193} \\D=13.892 units$

Given that 1 unit = 10metres

D = 13.892 * 10

D = 138.92 meters

Hence the distance between the coordinates in meters is 138.92m

In this problem,y = 1/(x2 + c)is a one-parameter family of solutions of the first-order DEy' + 2xy2 = 0.Find a solution of the f

trasher [3.6K]

Differentiate the given solution:

$y=\dfrac1{x^2+C}\implies y'=-\dfrac{2x}{(x^2+C)^2}$

Substitute $y$ and $y'$ into the ODE:

$-\dfrac{2x}{(x^2+C)^2}+2x\left(\dfrac1{x^2+C}\right)^2=0$

and it's easy to see the left side indeed reduces to 0.
