Solve the Differential Equation Using the Method of Variation of Parameters

question 28

Multiple Choice

Solve the differential equation using the method of variation of parameters.
$$y ^ { tt } - y ^ { t } = e ^ { 9 x }$$

• A)
• \(y ( x ) = c _ { 1 } + c _ { 2 } x e ^ { x } + \frac { e ^ { 9 x } } { 72 }\)
• B) \(y ( x ) = c _ { 1 } + x e ^ { 9 x }\)
• C) \(y ( x ) = c _ { 1 } + ( 1 + x ) x e ^ { 9 x }\)
• D) \(y ( x ) = c _ { 1 } + c _ { 2 } e ^ { x } + \frac { e ^ { 9 x } } { 72 }\)
• E) \(y ( x ) = c _ { 1 } + c _ { 2 } x e ^ { 9 x }\)

Definitions:

Renin Secretion

The process by which the kidneys release the enzyme renin, a key regulator of blood pressure and electrolyte balance.

Blood Pressure

The force of circulating blood on the walls of blood vessels, measured in millimeters of mercury (mmHg) and presented as two values: systolic and diastolic pressure.

Afferent Arterioles

Small blood vessels that carry blood toward the nephrons of the kidneys, regulating blood pressure and filtration rate.

Renin Secretion

Renin secretion involves the release of the enzyme renin from the kidneys, which plays a key role in the body's blood pressure regulation and electrolyte balance.
