Take 180 subtract 47 and 43. You get 90. So it would be C.

Find the equilibrium point for the pair of supply and demand functions. Demand: q=18/x Supply: q=x/2

storchak [24]

Answer:

The equilibrium point is at x = 6

Step-by-step explanation:

Given

$Demand (q) = \frac{18}{x}$

$Supply (q) = \frac{x}{2}$

Required

Determine the equilibrium point

The equilibrium point is determined by

$Demand = Supply$

Substitute values for Demand and Supply

$\frac{18}{x} = \frac{x}{2}$

Cross Multiply

$x * x = 18 * 2$

$x^2 = 36$

Take positive square root of both sides

$x = 6$

Hence;

<em>The equilibrium point is at x = 6</em>

A is a 4x4 matrix and A^2 + 4A - 5I = 0. If det(A+2I)>0, enter det(A+2I)

maw [93]

$\mathbf A^2+4\mathbf A-5\mathbf I=0$
$\implies\mathbf A^2+4\mathbf A+4\mathbf I=(\mathbf A+2\mathbf I)^2=9\mathbf I$
$\implies\det\bigg((\mathbf A+2\mathbf I)^2\bigg)=\det(9\mathbf I)$
$\implies\det(\mathbf A+2\mathbf I)^2=9^4\det\mathbf I$
$\implies\det(\mathbf A+2\mathbf I)=\pm\sqrt{9^4}$
$\implies\det(\mathbf A+2\mathbf I)=9^2=81$

where we take the positive root because we're told that the determinant is positive.
