Answer:
f. 85
Step-by-step explanation:
<u>All triangles add up to 180 degrees</u>
BCE=25
then you need to find DBC, you can do that since ABD is isocilies that means all sides are equal in length and angle so 180 divided by 3 (number of side) is 60
isoceles triangle have 2 sides that are equiangular, cince we know BCA is 25 we also know BAC is 25, leaving angle ABC to be 130 (180-50=130)
we subtract angle ABD from angle ABC to get angle DBC, leaving angle DBC to equal 70 degrees
since 70 (angle DBC) + 25 (Angel BCA)= 95
we just subtrract 95 from 180 to get the answer 85 (:

Answer:
A) In 2004 the population will reach 306 million.
B) In 2033 the population will reach 386 million.
Step-by-step explanation:
Given : The population of a certain country in 1996 was 286 million people. In addition, the population of the country was growing at a rate of 0.8% per year. Assuming that this growth rate continues, the model represents the population P (in millions of people) in year t.
To find : According to this model, when will the population of the country reach A. 306 million? B. 386 million?
Solution :
The model represent the population is
Where, P represents the population in million.
t represents the time.
A) When population P=306 million.
Taking log both side,
Therefore, In 2004 the population will reach 306 million.
B) When population P=386 million.
Taking log both side,
Therefore, In 2033 the population will reach 386 million.
The answer is A and B. :)
