Answer:

1222 billion dollars.

Step-by-step explanation:

To find the total increase from 1960 to 2010, we need to find the growth of each decade and sum them all:

In the period 1960-1970, we have x = 1, and the growth is:

y(1) = 43e(1/2) = 70.895

In the period 1970-1980, we have x = 2, and the growth is:

y(2) = 43e(2/2) = 116.8861

The growth in the following 3 periods are:

y(3) = 43e(3/2) =192.7126

y(4) = 43e(4/2) = 317.7294

y(5) = 43e(5/2) =523.8472

So the total growth in the period 1960 - 2010 is:

Total = y(1) + y(2) + y(3) + y(4) + y(5)

Total = 70.895 + 116.8861+192.726+317.7294+523.8472

Total = 1222.08\ billion\ dollars

Rounding to the nearest billion dollars, we have a total of 1222 billion dollars.

A large serving of soup from a take-out restaurant is 4/5 liter. The restaurant has 3 liters of soup. The diagram below models t
Airida [17]

Answer:

The quantity of total serving soup does restaurant has = T = 2 \dfrac{2}{5} liters .

Step-by-step explanation:

Given as :

The quantity of large serving soup = \dfrac{4}{5}  liters

The total quantity of soup does restaurant has = 3 liters

Let the quantity of total serving soup does restaurant has = T liters

So, According to question

The quantity of total serving soup does restaurant has = The quantity of large serving soup × total quantity of soup does restaurant has

Or, T =  \dfrac{4}{5} × 3

Or, T =  \frac{4\times 3}{5}

Or, T =  \dfrac{12}{5}

∴   T = 2 \dfrac{2}{5} liters

So, quantity of total serving soup does restaurant has = T = 2 \dfrac{2}{5} liters

Hence,The quantity of total serving soup does restaurant has = T = 2 \dfrac{2}{5} liters . Answer
