Given series is 2.4,-4.8,9.6,-19.2
To find whether it has common difference or common ratio let us find few differences and few ratios of consecutive terms.
Common difference of first 2 terms = 2nd term - first term = -4.8-2.4 = -7.2
Common difference of 2nd and 3rd terms = 3rd term - 2nd term = 9.6-(-4.8) = 14.4
Since those common differences are not equal the given series does not have common difference at all.
To check if it has common ratio or not let us find few ratios of consecutive terms.
Common ratio of first 2 terms =  =
 = 
Common ratio of 2nd and 3rd terms = 
So, the given series has common ratio as -2.0
 
        
                    
             
        
        
        
Answer: 572 yards
Step-by-step explanation:
The equation to find the area of a (base1 + base2) x height/2
The two bases are 14 and 30. Add them up to get 44.
Then, times that by the height. You get 1,144.
Lastly, divide 1,144 by 2. You get 572.
I hope this helped!
 
        
             
        
        
        
Answer:
49.5 mi
Step-by-step explanation:
Area of a triangle is   A = (height) X (base) / 2
So if you plug in the numbers you get:
806.9 = (32.6) X (base) / 2
1613.8 = (32.6) X (base)
1613.8 / 32.6 = base
base =  49.5 mi
