-7-(-6)-(-5)
+6+5
^
+11 -7 = +4 is the answer
The negative 6 and 5 turn into a positive because there is a double negative so you add both and then subtract -7

(5)/(9,) (5)/(3,) 5,15,45 are these numbers a sequence of geometric numbers

Ad libitum [116K]

<u>Answer:</u>

It is a sequence of geometric numbers.

<u>Step-by-step explanation:</u>

A sequence or series of numbers where each term after the first term is found by multiplying it with a fixed or certain number is called a geometric sequence or geometric progression.

We can check whether the given series is geometric or not by dividing each term by its previous term to see if their common ratio is the same.

$\frac{45}{15}=3$

$\frac{15}{5} =3$

$\frac{5}{\frac{5}{3} } =3$

$\frac{\frac{5}{3} }{\frac{5}{9} } =3$

Since the common ratio is the same, therefore it is a sequence of geometric numbers.

For each initial value problem, determine whether Picard's Theorem can be used to show the existence of a unique solution in an

Alinara [238K]

Answer:

Part a: $f , \, f_y$ is continuous at the initial value (0,0) so due to Picardi theorem there exists an interval such that the IVP has a unique solution.

Part b: $f_y$ is not continuous at the initial value (0,0) so due to Picardi theorem there does not exist an interval such that the IVP has a unique solution.

part c: $f , \, f_y$ is continuous at the initial value (0,1) so due to Picardi theorem there exists an interval such that the IVP has a unique solution.

Step-by-step explanation:

Part a

as $y^{' }=ty^{4/3}$

Let

$f(t,y)=ty^{4/3}$

Now derivative wrt y is given as

$f_y=\frac{4}{3}ty^{1/3}$

Finding continuity via the initial value

$f$ is continuous on $R^2$ also $f_y$ is also continuous on $R^2$

Also

$f , \, f_y$ is continuous at the initial value (0,0) so due to Picardi theorem there exists an interval such that the IVP has a unique solution.

Part b

as $y^{' }=ty^{1/3}$

Let

$f(t,y)=ty^{1/3}$

Now derivative wrt y is given as

$f_y=\frac{1}{3}ty^{-2/3}$

Finding continuity via the initial value

$f$ is continuous on $R^2$ also $f_y$ is also continuous on $R^2$

Also

$f_y$ is not continuous at the initial value (0,0) so due to Picardi theorem there does not exist an interval such that the IVP has a unique solution.

Part c

as $y^{' }=ty^{1/3}$

Let

$f(t,y)=ty^{1/3}$

Now derivative wrt y is given as

$f_y=\frac{1}{3}ty^{-2/3}$

Finding continuity via the initial value

$f$ is continuous on $R^2$ also $f_y$ is also continuous on $R^2$ when $y\neq 0$

Also

$f , \, f_y$ is continuous at the initial value (0,1) so due to Picardi theorem there exists an interval such that the IVP has a unique solution.
