n = 8
the sum to n terms of a geometric sequence is
=
where a is the first term and r the common ratio
here a = 16 and r = = = - 2
= ( 16( 1 - ( - 2 )^n )/1 - (- 2 )) = - 1360
( 1 - (- 2 )^n ) = - 1360
multiply both sides by
1 - (- 2 )^n = - 255
- (- 2 )^n = - 256
)-2)^n = 256
note that and = 256
hence n = 8
Answer:
x = 2 * (y/5) feets
Step-by-step explanation:
Given that :
Actual dimension of mural = 15 feet by 8 feet
Scale drawing = 2 feet : 5 feet
2 feets on the scale drawing represents 5 feets of the actual drawing.
Drawing length (x)
Actual mural length (y)
x = 2 * (y/5) feets
Hence, dimension of scale drawing:
x = 2 * (15/5) ; x = 2 * (8/5)
x = 6 feets ; 3.2 feets
