Suppose a consumption function is given as c = $500 0.75yd. the marginal propensity to consume is:______
kobusy [5.1K]

In the the case above, if the consumption function is: C = $500 + 0.75 × YD, from the equation, the The marginal propensity to consume is option C) 0.75.

<h3>What is MPC?</h3>

The marginal propensity to consume which is MPC is the aspect of each extra money that is dollar of a household's income that is said to be used, consumed or spent.

Note that Consumer behavior in regards to saving or spending has a very vital impact on the economy of a country.

From the formula given, the breakdown is:

YD = disposable income.

Autonomous consumption = $500.

The marginal propensity to consume  = 0.75.

Therefore, In the the case above, if the consumption function is: C = $500 + 0.75 × YD, from the equation, the The marginal propensity to consume is option C) 0.75.

See full question below

Suppose that the consumption function is: C = $500 + 0.75 × YD

(Scenario: Consumption Spending) The marginal propensity to consume is:

A) $500.

B) 0.

C) 0.75

D) 0.2.

A block is at rest. The coefficients of static and kinetic friction are s = 0.81 and k = 0.69, respectively. The acceleration of
lys-0071 [83]

Answer:

Explanation:

a ) The angle required = angle of repose = θ

Tanθ = .81

θ = 39⁰

b ) when angle of incline θ = 44

Net force on the block = mg sinθ - μ mg cosθ where μ is coefficient of kinetic friction

acceleration = gsinθ - μ g cosθ

= 9.8 ( sin44 - μ cos44 )

= 9.8 ( .695 - .69 x .72 )

= 9.8 ( .695 - .497 )

= 1.94 m /s²

A tight knot can be easily opened by using a long spanner. Give reason.
olga nikolaevna [1]

Answer:

Torque

Explanation:

loosening loosening a boat requires a certain amount of torque which is the product of the force acting on the wrench and the moment arm, or distance from the center of rotation at which the force is applied. the longer the handle, the last force it takes to generate the same amount of torque

A 1470-kilogram truck moving with a speed of 27.0 m/s runs into the rear end of a 1010-kilogram stationary car. If the collision
Gre4nikov [31]

Answer:

\Delta KE = 218.375\ kJ

Explanation:

Given,

Mass of the truck, M =  1470 Kg

initial speed of the truck, u = 27 m/s

mass of car, m = 1010 Kg

initial speed of car, u' = 0 m/s

Final speed, V = ?

Using conservation of momentum

Mu = (M+m) V

1470\times 27 = (1470 + 1010 ) V

V = 16\ m/s

Change in kinetic energy

\Delta KE = \dfrac{1}{2} Mu^2 - \dfrac{1}{2}(M+m)V^2

\Delta KE = \dfrac{1}{2}\times 1470\times 27^2 - \dfrac{1}{2}\times (1470 + 1010)\times 16^2

\Delta KE = 218.375\ kJ

Change in KE = \Delta KE = 218.375\ kJ
