AB and AC are tangent. Find AB
LuckyWell [14K]

Answer:

AB =  \frac{11}{2}

Step-by-step explanation:

Given

The above diagram

AB = 3y + 4

AC = 11y

Required

Determine length AB

Tangents drawn from the same point of a circle are equal;

<em>This implies that</em>

AB = AC

Substitute values for AB and AC

3y + 4 =11y

Subtract 3y from both sides

3y - 3y + 4 = 11y - 3y

4 = 8y

Divide both sides by 8

\frac{4}{8} = \frac{8y}{8}

\frac{4}{8} = y

\frac{1}{2} = y

Substitute \frac{1}{2} for y in AB = 3y + 4

AB = 3 * \frac{1}{2} + 4

AB =  \frac{3}{2} + 4

AB =  \frac{3 + 8}{2}

AB =  \frac{11}{2}

Find the largest interval which includes x = 0 for which the given initial-value problem has a unique solution. (Enter your answ
Ivan

Answer:

(-\infty,3)

Step-by-step explanation:

We are given that

(x-3)y''+4y=x

y''+\frac{4}{x-3}y=\frac{x}{x-3}

y(0)=0

y'(0)=1

By comparing with

y''+p(x)y'+q(x)y=g(x)

We get

p(x)=\frac{4}{x-3}

g(x)=\frac{x}{x-3}

q(x)=0

p(x),q(x) and g(x) are continuous for all real values of x except 3.

Interval on which p(x),q(x) and g(x) are continuous

(-\infty,3)and (3,\infty)

By unique existence theorem

Largest interval which contains 0=(-\infty,3)

Hence, the larges interval on which includes x=0 for which given initial value problem has unique solution=(-\infty,3)
