Since he makes 3 cookies more than her every hour, he needs to work for as many hours needed to make 18 more than her. 18/3 is 6 which is why he needs to work for 6 hours to get the amount equal to Sydney’s.

Find the general solution for differential equation<br><br> (D4 - 5D3 + 5D2 + 5D - 6)y = 0
slava [35]
Given differential equation, (D4 - 5D3 + 5D2 + 5D - 6)y = 0

=> For general solution of equation,

Solve D4 - 5D3 + 5D2 + 5D - 6 = 0

=> D4 - 5D3 + 6D2 - D2 + 5D - 6 = 0

=> D2 (D2 - 5D + 6) - (D2 - 5D + 6) = 0

=> (D2 - 5D + 6)(D2 - 1) = 0           ................................(1)

Now

D2  - 1 = (D - 1)(D + 1)  and

Factors of D2 - 5D + 6

D2 - 5D + 6 = D2 - 2D - 3D + 6

= D(D - 2) - 3(D - 2)

= (D - 3)(D - 2)

Therefore, equation (1) implies

(D2 - 5D + 6)(D2 - 1) = (D - 3)(D - 2)(D - 1)(D + 1) = 0

=> D = 3, 2, 1, -1 or D = -1, 1,, 2, 3

=> General solution of differential equation is,<span>

=><span> y = C1 e-x + C2 ex + C3 e2x + C4 e3x</span> .

Hope it helps

Which of the following functions shows the quadratic parent function, f(x)= x^2, shifted left?
ki77a [65]
The answer is C) because you are moving left 8 units. In the inside of the parenthesis it says +8 however its counterintuitive, so the function is actually moving left. You can check on desmos.com a website for graphing functions.

Given :

On a number line, suppose the coordinate of A is 0, and AR = 15.

To Find :

the possible coordinates of the midpoint of AR.

Solution :

Their can be two points R which is at a distance of 15 units from the A .

One is -15 and other is 15.

Now, mid-point of A(0) and R(-15) is M (-7/2).

Also, mid-point of A(0) and R(15) is M (7/2).

Therefore, possible coordinates of the midpoint of AR is 7/2 , -7/2.

Hence, this is the required solution.
