Complete Question

The complete question is shown on the first uploaded image

Answer:

No singular point due to the exponent in the solution

The interval is $-\infty$

NONE

Step-by-step explanation:

From the question we are told that

$\frac{dy}{dx} = 9y$

The generally solution is mathematically represented as

$\frac{dy }{dx} = 9y$

=> $\frac{dy}{y} = 9dx$

integrating both sides

$\int\limits {\frac{ dy}{y} } \, = \int\limits {9} \, dx$

=> $lny = 9x + c$

=> $y = e^{9x +c }$

=> $y = e^{9x} e^{c}$

Here $e^c = C$

=> $y = C e^{9x}$

From the above equation we see that the domain for x has no singular point the interval is

$-\infty$

Also there is no transient term in the general solution obtained because as $x \to \infty$ there no case where $y \to 0$

Can someone please help me? I don't understand question d.

Sedaia [141]

Answer:

Step-by-step explanation:

From the previous answers you know the angles and side lengths of the triangle:

α = 60°

Ф = 30°

and the side lengths:

1,2 and √3.

Remember:

sin = opposite / hypotenuse

cos = adjacent / hypotenuse

tan = opposite / adjacent

Now you can read off from the triangle:

sin 30° = 1/2

cos 60° = 1/2

sin 60° = √3/2

cos 30° = √3/2

tan 30° = 1/√3

tan 60° = √3

Please help me with geometry questions :((

snow_lady [41]

Answer:

$14.\:\:\overline{RT}=3.3\:ft$

Step-by-step explanation:

Using the definition of similar triangle, we have the equation for problem no. 14 as:

$\frac{\overline{QT}}{\overline{RT}}=\frac{\overline{RT}}{\overline{TS}}\\\\\frac{5}{x}=\frac{x}{2.2}\\\\\Rightarrow x=3.3$

Best Regards!
