Answer:
After n years, 120,000(1 - 0.92ⁿ) units, will be in use.
Step-by-step explanation:
Given;
estimated annual sales, a = 9600 units
determine common ratio, r;

sum of the units in use after n years is calculated by applying sum of nth term;


Therefore, after n years, 120,000(1 - 0.92ⁿ) units, will be in use.
Answer:
41.802 feet
Step-by-step explanation:
Given that a 92 ft path cuts diagonally from Mateo St. to Cove St. It makes an angle of 68° with Cove St. and an angle of 34° with Mateo St.
We can visualize a triangle formed by the three streets One side is 92 feet.
Angle opposite 92 feet = 
Let x be length of Cove st and y length of Mateo st.
Using sine angle for triangles,

Simplify to get
x=52.595
y=87.207
Distance saved= 
The hypotenuse would be 9 inches as 6 is equal to 2/3 of 9 :)
Answer:
If area = length * width that means the answer is 4x * 5x = 20x².
