Answer:
In 1981 was the building worth double it’s value.
Step-by-step explanation:
Given : A townhouse in San Francisco was purchased for $80,000 in 1975. The appreciation of the building is modeled by the equation :
, where t represents time in years.
To find : In what year was the building worth double it’s value in 1975?
Solution :
The amount is $80,000.
The building worth double it’s value in 1975.
i.e. amount became A=2(80000).
Substitute in the model,



Taking log both side,



i.e. Approx in 6 years.
So, 1975+6=1981
Therefore, in 1981 was the building worth double it’s value.
First find the area of the triangle at the end.
Area of a triangle is 1/2 x base x height.
The triangle is a right triangle with a base of 4 and height of 3
area = 1/2 x 4 x 3 = 6 square cm
Now to find the volume multiply the area of the triangle by the length of the prism.
volume = 6 square cm x 11 cm = 66 cubic cm.
answer: 66 cm^3
