Option B: The area of the trapezoid is 157.5 m²
Explanation:
We need to determine the area of the trapezoid.
The area of the trapezoid can be determined by the formula,
where h is the height, a and b are the base of the trapezoid.
From the figure, it is obvious that 
, 
and 
Substituting these values in the formula, we have,
Simplifying the terms, we have,
Multiplying the terms in the numerator, we have,
Dividing, we get,
Thus, the area of the trapezoid is 157.5 m²
Hence, Option B is the correct answer.
Answer:
Estimated To Be 167 Million
Step-by-step explanation:
The exponential growth formula is given by
where: P is the population of the country, t years after the initial year (i.e. in this case, 1994). is the initial population of the country (i.e. the population of the country in 1994).
r is the growth rate of the population and
t s the number of years after the initial year.
We obtain the value of r by comparing the growth between 1994 and 1998.
Here: P = 146, , and t = 4 years
Thus To estimate the population of the country in 2011, we note that 2011 is 17 years after 1994.
Thus, the population of the country in 2011 can be estimated to be
million
Therefore, the population of the country in 2011 can be estimated to be 167 million to the nearest million
Answer:
This would be a decay function.
Step-by-step explanation:
When a function is a growth function that means that it is growing but a decay function means that it is getting smaller.
The answer is this: $3.60
4 x 10 = 40 - 0.4 = 3.6
