Because if you raise it to the first its the same number and if you raise it to the zero power it becomes one

Let y = y1(t) be a solution of y' + p(t)y = 0 (1)

murzikaleks [220]

Answer:

a) See proof below

b)The result does not violate uniqueness of solutions.

Step-by-step explanation:

Suppose $y_1(t)$ is a solution of

$y'+p(t)y=0$

then

$y'_1+p(t)y_1=0$

If $y_2(t)$ is a solution of

$y'+p(t)y=g(t)$

then

$y'_2+p(t)y_2=g(t)$

To show that $y_1+y_2$ is a solution of equation (2) we have to show that

$(y_1+y_2)'+p(t)(y_1+y_2)=g(t)$

But

$(y_1+y_2)'+p(t)(y_1+y_2)=(y'_1+y'_2)+(p(t)y_1+p(t)y_2)=(y'_1+p(t)y_1)+(y'_2+p(t)y_2)=0+g(t)=g(t)$

which is what we wanted to show.

The results of the above problem does not violate uniqueness of solutions, because the solution is unique for each specific given initial condition, but there are no initial conditions stated.

julsineya [31]

Answer:

5 Peonies and 7 Callas

Step-by-step explanation:

if you set all twelve flowers as calla's, they add up to 42. 52 - 42 = 10. Every time you change a Peony with a Calla, it adds 2 dollars to the total. 10/2 = 5. That means there are 5 Peonies and 7 Callas.
