The limit of the function cos(1/x)  as x approaches zero can be determined by substituting x with zero to the expression given. IN this case, 1/0 is equal to infinity. Using the rule of cosines, the maximum value of the cosine expression is 1. Hence the limit should be 1.

1990 population was 254 million in 2014 it was 303 what was the percentage increase in the population
Ann [662]

Answer:

19.29%

Step-by-step explanation:

Given

Population in 1990

= 254000000

Population in 2014

= 303000000

Increase = 303000000 - 254000000

= 49000000

% increase in population =

Increase /initial population x 100%

That’s

49000000/254000000 x 100%

0.1929 x 100%

19.29%

The population increased by 19.29%

The dimensions of a cube are doubled. The volume of the enlarged cube is how many times the volume of the original cube?
Elza [17]
The volume is multiplied by 8. For example if you have a 1x1x1 cube the volume is 1. If you have a 2x2x2 cube the volume is 8. If you have a 4x4x4 the volume is 64.

For number 3 it says
X - 9 for x=-5
X-9 = ___ -9
It gave you your x so you would just substitute and in result you will have an equation of -5 -9
