Which proportion correctly shows the equivalence of two ratios?

lina2011 [118]

C. 4:5=32:40 is your answer

Treat each ratio like fractions. Note the equal sign. This means that, when each fraction is simplified, they would be the same.

4/5 = 4/5

(32/40)/(8/8) = 4/5

4/5 = 4/5

∴ (C) is your answer

G find the domain for the particular solution to the differential equation dy dx equals the quotient of negative 1 times x and y

faust18 [17]

$\frac{dy}{dx} = \frac{-x}{y}$
by separating the variables
∴ y dy = -x dx
integrating both sides with respect to x
∴ ∫y dy = ∫-x dx
∴ $\frac{ y^{2} }{2} = - \frac{ x^{2} }{2} +c$
finding c using initial condition y(2) = 2.
∴ $\frac{ 2^{2} }{2} = - \frac{ 2^{2} }{2} +c$
∴ c = 4
∴ $\frac{ y^{2} }{2} = - \frac{ x^{2} }{2} +4$
multiplying all the equation by 2
∴ y² = -x² + 8
∴ x² + y² = 8
The resultant equation represents the equation of the circle
with center (0,0) and radius = √8 = 2√2
so, the domain of this function is [-2√2 , 2√2]
