Answer:

The GDP gap is 9 % when there is 4.5 % unemployment.

Step-by-step explanation:

The statement shows a reverse relationship, where an increase in unemployment is following by decrease in potential GDP and can be translated into the following rate:

$r = \frac{2\,\% \,GDP}{1\,\% unemp.}$

The GDP gap at a given increase in unemployment can be estimated by the following expression:

$\frac{g}{u} = r$

$g = r\cdot u$

Where:

$r$ - GDP gap-unemployment increase rate, dimensionless.

$u$ - Increase in unemployment rate, measured in percentage.

$g$ - GDP gap, measured in percentage.

If $r = \frac{2\,\% \,GDP}{1\,\% unemp.}$ and $u = 4.5\,\%\,unemp.$ , the GDP gap is:

$g = \left(\frac{2\,\%\,GDP}{1\,\%\,unemp.} \right)\cdot (4.5\,\%\,unemp.)$

$g = 9\,\%\,GDP$

The GDP gap is 9 % when there is 4.5 % unemployment.

angle 3 and angle 4 form a linear pair. the measure of angle 3 is four more than three times the measure of angle 4. find the me

lisabon 2012 [21]

Since angles 3 and 4 form a linear pair, the sum of the measures of their angles must add up to 180.

We can define angle 3 as x, and angle 4 as (180-x).

x = 3 ( 180 - x ) + 4.

Solving for x, we get x=138. This is angle 3. Angle 4 is 180-138, so angle 4 is 42.

What is the midpoint of EC ?

sergij07 [2.7K]

Given:

Given that the graph OACE.

The coordinates of the vertices OACE are O(0,0), A(2m, 2n), C(2p, 2r) and E(2t, 0)

We need to determine the midpoint of EC.

Midpoint of EC:

The midpoint of EC can be determined using the formula,

$Midpoint=(\frac{x_1+x_2}{2}, \frac{y_1+y_2}{2})$
