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.

Which term describes the point when two objects reach the same temperature and there is no longer a transfer of energy through h
yaroslaw [1]
The term you need to know is equilibrium. Technically it means that heat gained = heat lost. Normally in beginning chemistry classes the evidence for this condition is a stable temperature.

A shark swims around his circular pool. What is the centripetal force of the 681kg shark if the pool has a diameter of 14m and i
blsea [12.9K]
<span>29 Newtons
   Centripetal force is modeled by the equation:
  F = MV^2/R where
 F = force
 M = Mass
 V = Velocity
 R = Radius

   I will assume the shark is swimming in a circle with a radius of 14 m / 2 = 7 m. The actual radius will be smaller, but I'll assume that the question is simply poorly worded. So we need to calculate the velocity of the shark. The circumference of the circle is pi*14m = 43.98229715 m. And since velocity is defined as distance over time, we have a velocity of 43.98229715 m / 80 s = 0.549778714 m/s.

   Now substitute the known values into the equation for centripetal force.
 F = MV^2/R
 F = 681 kg * ( 0.549778714 m/s)^2 / 7m
 F = 681 kg * 0.302256635 m^2/s^2 / 7m
 F = 205.8367683 kg*m^2/s^2 / 7m
 F = 29.40525261 kg*m/s^2
 F = 29.40525261 N
   Rounding to 2 significant figures gives a force of 29 Newtons.</span>

Two football players are pushing a 60 kg blocking sled across the field at a constant speed of 1.5 m/s. the coefficient of kinet
Sladkaya [172]
F(friction) = u F(normal) 
so, F(friction) = (.30)(60*9.81) = 177 N 
F = ma 
so, 177 = (60)a, a = 177/60 = 2.9m/s^2 
v(final)^2 = v(initial)^2+2ax 
so, 0 = 1.5^2 + 2(-2.9)x, x = 2.25/(2*-2.9) = -.38793 the negative indicates that the direction of accel is opposite of direction of speed. 
-0.39 meters is the answer.
