Find the value of x when a⊥b and b||c.

dem82 [27]

Answer: 8

Step-by-step explanation: Because a is perpendicular to b, the value of 9x + 18 = 90. If we subtract 18 from both sides, it becomes 9x = 72. Divide by 9 on both sides to get 8

Given the following rst-order IVP: (e x + y) dx + (2 + x + yey ) dy = 0 y (0) = 1 (a) Show that this equation is exact. (b) Solv

ankoles [38]

Answer:

let M=ex +y and N=2 +x +yey

(a) σM/σy =1 and σN/σx = 1

since σM/σy = σN/σx , it is an exact equation

(b) ∫M dx + ∫terms of N not containing x

∫(ex + y) dx +∫yey + 2 dy

xy + ex +yey -ey +2y=C

C=3

(d) from the differential equation given

by dividing through by dx

dy/dx = (-y-ex) /(2+x+yey)

from the solution

$\frac{d}{dx}$ (xy + ex +yey -ey =2y)= $\frac{d}{dx}$ (3)

x $\frac{dx}{dy}$ + y + ex + yey $\frac{dy}{dx}$ + ey $\frac{dx}{dy}$ - ey $\frac{dy}{dx}$ + 2 $\frac{dy}{dx}$ = 0

$\frac{dy}{dx}$ = (-y-ex) /(2+x+yey)

Step-by-step explanation:

1. integrate with respect to x keeping y constant

2. integrate terms without x in N

3. Result of 1 + result 2= C

4. insert the condition given into 3

5. compare the solution of 4 to the differential equation

1/4k = 3 (-1/4k + 3)

Arada [10]

Answer:

For the expression $\frac{1}{4} k = 3 (-\frac{1}{4}k +3)$

k = 9 is the required solution.

Step-by-step explanation:

Here, the given expression is $\frac{1}{4} k = 3 (-\frac{1}{4}k +3)$

Solving the above expression for k, we get:

$\frac{1}{4} k = 3 (-\frac{1}{4}k +3) \implies \frac{k}{4} = (\frac{-3}{4}k) + 9$

or, $\frac{k}{4} + (\frac{3}{4}k) = 9 \implies \frac{k + 3k}{4} = 9$

or, $\frac{4k}{4} = 9 \implies k =9$

or, k = 9

Hence for the expression $\frac{1}{4} k = 3 (-\frac{1}{4}k +3)$

k = 9 is the required solution.
