The graph represents a hypothetical picture of the U.S. economy. The Federal Reserve (Fed) determines that the economy must be s

Thepotemich [5.8K]

The course of action that would be used to achieve this goal would be

Buying $65 billion of government bonds

<h3>How to solve for the solution</h3>

Given that the feds are wanting to stimulate the economy, there is going to be a right shift in the aggregate demand.

There would be an increase in money supply given that the feds are going to buy bonds.

<h3>The money multiplier</h3>

1/0.1= 10

<h3>Change in reserve</h3>

= $650 billion/10= $65 billion

Hence we conclude that the way of achieving the goal would be by Buying $65 billion of government bonds

Newton’s law of cooling states that for a cooling substance with initial temperature t0, the temperature t(t) after t minutes ca

antoniya [11.8K]

The cooling rate of the substance is approximately 0.0732.

According to the statement, the Newton's law of cooling is defined by the following formula:

$T(t) = T_{s} + (T_{o}-T_{s})\cdot e^{-k\cdot t}$ (1)

Where:

$T_{s}$ - Final temperature, in degrees Celsius.
$T_{o}$ - Initial temperature, in degrees Celsius.
$t$ - Time, in minutes.
$k$ - Cooling rate, in $\frac{1}{min}$ .
$T(t)$ - Current temperature, in degrees Celsius.

Please notice that substance reaches thermal equilibrium when $T(t) = T_{s}$ , that is when temperature of the substance is equal to the temperature of surrounding air.

If we know that $T_{o} = 80\,^{\circ}C$ , $t = 15\,min$ , $T_{s} = 50\,^{\circ}C$ and $T(15) = 60\,^{\circ}C$ , then the cooling rate of the substance is:
