Answer:

44

Step-by-step explanation:

k=1: 2*1-4 = -2

k=2: 2*2²-4 = 4

k=3: 2*3²-4 = 14

k=4: 2*4²-4 = 28

-2 + 4 + 14 + 28 = 44

Macroeconomics calculation
3241004551 [841]
So if the equation you showed is a given, then you are on the right track. I'm trying to figure out where financial investment spending is in the equation, though?
I found this: The following equation is used to calculate the GDP: GDP = C + I + G + (X – M) or GDP = private consumption + gross investment + government investment + government spending + (exports – imports). ... It transforms the money-value measure, nominal GDP, into an index for quantity of total output.

72,000,000+12,000,000+25,000,000+ G + 5,000,000 = 123,000,000
It's easier to solve it without the zeros:
G=123 - 72- 12 - 25 - 5
G= 9 or 9,000,000 is government spending

Remember that (X-M) is NET EXPORTS. They will either give you exports and imports so that you have to subtract, or net exports that you can just plug in. Make sense?

sweet [91]

Answer:

4 sq. units

Step-by-step explanation:

Because the vertices of S₂ are the midpoints of S₁, the area of S₂ will be half of that of S₁ which is 16 / 2 = 8. Similarly, because the same process is carried out on S₂ to make S₃, the area of S₃ is 8 / 2 = 4 sq. units.
