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:
In the period 1970-1980, we have x = 2, and the growth is:
The growth in the following 3 periods are:
So the total growth in the period 1960 - 2010 is:
Rounding to the nearest billion dollars, we have a total of 1222 billion dollars.
Value of x for which the two points are on the line with the given slope (1,-1) and (x,7): undefined is .
<u>Step-by-step explanation:</u>
Here we have to Find x so that the two points are on the line with the given slope (1,-1) and (x,7): undefined . Let's find out:
We know that for any two points given as slope of line is determined by :
⇒
According to question we have two points as ∴
⇒
⇒
But slope is undefined which is only possible when denominator is zero i.e.
⇒
⇒
Therefore , Value of x for which the two points are on the line with the given slope (1,-1) and (x,7): undefined is .
