Question

Given that, for some a, b, c, d, e, f, g, h, i ∈ R, [a b c d e f g h i ] = 5, evaluate the following determinants:

(c) [ka ld mg

kb le mh

kc lf mi] Here, k, l, and m are non-negative constants.

Answer #1

Here, basically we use some basic properties of the determinants .

Determinant of matrix has a property that:

**" Determinant of any matrix is equal to determinant of
its transpose."**

Thus, desired determinant is 5klm.

9. Let S = {a,b,c,d,e,f,g,h,i,j}.
a. is {{a}, {b, c}, {e, g}, {h, i, j}} a partition of S?
Explain.
b. is {{a, b}, {c, d}, {e, f}, {g, h}, {h, i, j}} a partition
of S? Explain. c. is {{a, b}, {c, d}, {e, f}, {g, h}, {i, j}} a
partition of S? Explain.

Given a closed economy in the long run (classical model):
Y=F(K,L)
Y=C+I+G C=c(Y-T)
I=I(r)
G and T set by Government policy.
For the following changes in the economy, show the impact of the
change on the loanable fund market. Use a fully labeled graph.
Also state the impact of the change on the following variables:
Y, C, G, S, I and r.
1) A decrease in Government Spending.
2) A decrease in Taxes.
3) An increase in Investment demand.

Identify the strategy represented in each of the following
arguments taken from
budget discussions:
a. A bill to increase the number of women eligible for
Medicaid-funded prenatal
assistance in this state would not only save lives, but also cut
state costs for
care of low-birth-weight babies and children with disabilities.
Studies have
shown that every dollar spent on prenatal care reduces long-term
health-care
expenditures by $3.38.
