perimeter of rectangle = 20+20 +15+15 = 70 yards = 70*3 = 210 feet

210/5 = 42 seconds

 Courtney walks it in 42 seconds


the diagonal = 15^s + 20^2 = 225+400=625

sqrt(625) = 25 yards

Natalie walks 20 +15 +25 = 60 yards

60*3 = 180 feet

180 /5 =36 seconds


42 - 36 =  6 seconds faster

According to Okun's law, if the unemployment rate goes from 5% to 3%, what will be the effect on the GDP?
olga2289 [7]

Answer:

D. It will increase by 1%.

Step-by-step explanation:

Given

u_1 = 5\% --- initial rate

u_2 = 3\% --- final rate

Required

The effect on the GDP

To calculate this, we make use of:

\frac{\triangle Y}{Y} = u_1 - 2\triangle u

This gives:

\frac{\triangle Y}{Y} = 5\% - 2(5\% - 3\%)

\frac{\triangle Y}{Y} = 5\% - 2(2\%)

\frac{\triangle Y}{Y} = 5\% - 4\%

\frac{\triangle Y}{Y} = 1\%

<em>This implies that the GDP will increase by 1%</em>
