Explain how the market demand curve for a normal good will shift
(ie left, right or no shift in each of the following cases? What
then will happen to the equilibrium price and quantity?
a) The price of a substitute good falls
b) The price of a complementary goods falls
c) The price of the good decreases
d) Tastes shift away from good
1. Explain the following.
a. Compare the right and left ventricular pressures and right
and left ventricular volumes.
b. What will happen to cardiac output during exercise? Explain
what physiological changes occur that cause this change in cardiac
output?
1. An astronaut with a spaceship moves from left to right
following the curve y = x^2. When he turns off the engine, the
spacecraft will move along the tangent line at the point where he
is at that moment. At what point does he have to turn off the
engine to reach the point (4,15)?
6) There are two tangents to the function graph y = 4x − x^2
through the point (2,5). Determine the tangent equation. Hint:
Suppose...
A word that reads the same from left to right and right to left
is a palindrome. For example, "I", "noon" and "racecar"
are palindromes. In the following, we consider palindromic
integers. Note that the first digit of an integer
cannot be 0.
How many positive palindromic integers are 5-digit long and
contain 7 or 8?
Determine whether the events below will cause the aggregate demand curve to shift to the left or to the right. Assume the price le remains constant a. Government purchases increase by $2 billion. Aggregate demand shifts (Click to select) b. Real interest rates increase. Aggregate demand shifts (Click to select) c. Taxes increase. Aggregate demand shifts (Click to select) d. Aggregate consumption decreases as consumer confidence falls. Aggregate demand shifts (Click to select) .
Indicate what happens, in the short run, to the aggregate
demand curve (shift right or left), real GDP (increase or
decrease), and the price level (increase or decrease) in each of
the following cases:
a) The interest rate rises,
b) Wealth falls,
c) The dollar depreciates relative to foreign
currencies,
d) Households expect lower prices in the future
e) Business taxes rise.
Predict how the equilibrium will shift (to the left, to the
right or no change) with each of the following stresses: a. 2H2 (g)
+ 2NO (g) → N2 (g) + 2H2O (g) i. Increase [H2] ii. Decrease [NO]
iii. Decrease the pressure (by increasing the volume) b. CO (g) +
1/2O2 (g) → CO2 (g) + 283 kJ i. Decrease temperature ii. Increase
pressure (by adding He (g)) c. H2O (l) → H + (aq) + OH− (aq) i....
