Computing growth rates (i): suppose xt=(1.04)^t and yt=(1.02)^tcalculate the growth rate of zt in each of the following cases: (a) z=xy(b) z=x/y(c) z=y/x(d) z=x^1/2 y^1/2(e) z=(x/y)^2(f) z=x^-1/3y^2/3

Step-by-step explanation:

We are given the following in the question:

We have to find the growth rate z(t) in each of the following cases:

(a) z = xy

(b) z=x/y

(c) z=y/x

(d) z=x^(1/2) y^(1/2)

(e) z=(x/y)^2

(f) z=x^(-1/3)y^(2/3)

341

step-by-step explanation:

all you have to do is 9x31 (which equals 279) and then 20x31 (which equals 620). then you have to subtract. 620-279=341.

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.
