Answer:
A =80.5 ft^2
Step-by-step explanation:
The area of a triangle is given by
A = 1/2 bh
The base is 14 ft and the height is 11.5 ft
A = 1/2 * 14 * 11.5
A =80.5 ft^2
 
        
             
        
        
        
2500x0.80=2000 so i think it would be 2000 in 8 years 
or if youre adding the 2000 to the already existing 2500 then it would be 4500.

Answer:
That's incorrect. The simplest way to show this is by evaluating the functions at a given point. Let's say x=0, then:
Sin(-x) = Sin(0) = 0
-cos x = -cos (0) = -1
Therefore, Sin(-x)≠-cos x.
