Y = C + I + G + NX (1) C = α + β(1 − t)Y (α > 0; 0 < β < 1) (2) I = θ − δi (θ > 0; δ > 0) (3) G = g + T (g > 0) (4) NX = (X − M) (5) Using differential calculus: solve for the change in national GDP(Y) with respects to a change in government expenditure(g)
Is C the correct
answer for #1?
I thought that
theanswer would be (i), (ii)&(v)... but I don't see it, or i'm
wrong?
For #5: is b or c
the answer? I'm not sure, because but have unpair bonds
#7: is (D)four?
#8: what ir means by various resonance?
# 10: i know is SP2, but i don't get the other part.
(c). Determine the Fourier transform of s(t)={! -1<i<1 14 > 1
Consider the following C++ code segment: if (i j) cout << "1"; else if ((i &j) < 3) cout << "2"; else if (i < (j-1)) cout << "3"; else cout << "4"; cout << "5"; If the value of iis 5and the value of jis 6, which of the options below gives the correct output? 1. 25 2. 35 3. 15 4. 45
