Answer:

Exact Form: -53/12

decimal form: -4.416

mixed number -4 5/12

Step-by-step explanation:

convert mixed numbers into improper fractions: -2 3/3 +(5 1/2)+ 8 3/4

convert mixed numbers into improper fractions: =11/2  =-\frac{23}{3}+\left(-\frac{11}{2}\right)+\frac{35}{4} =

-\frac{23}{3}+\left-\frac{11}{2}\right+\frac{35}{4}=-\frac{92}{12}-\frac{66}{12}+\frac{105}{12}

\frac{-92-66+105}{12}

add/subtract the numbers: -92-66+105=-53

-53/12

apply the fraction rule: \frac{-a}{b} = -\frac{a}{b\\}

=-\frac{53}{12}\\

The parallelogram is reflected across the line y = x. Which of the following are coordinates of a vertex of the image?
Korvikt [17]

Answer:

A'(1,-5)

Step-by-step explanation:

The coordinates of the given quadrilaterals are

A(-5,1),B(-4,3),C(-2,1),D(-3,-1)


The reflection in the line y=x has the mapping,

(x,y)\rightarrow(y,x)


We just have to swap the coordinates.


This implies that,


A(-5,1)\rightarrow A'(1,-5)


B(-4,3)\rightarrow B'(3,-4)


C(-2,1)\rightarrow C'(1,-2)


D(-3,-1)\rightarrow D'(-1,-3)


Therefore the correct answer is A.

A'(1,-5)

For every 1% increase in
givi [52]

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.
