the common ratio in geometric series is 0.5 and the first term is 256. what is the sum of the first 6 terms in the series?

501.76

Step-by-step explanation:

common ratio r = 0.5

first term a = 256

sum of G.p = Sn= a( r^n -1)/r-1

sum of the first 6 terms =

S6 = 256( 0.5^6 - 1)/ 0.5 - 1

= 256( 0.0156 - 1)/-0.5

= 256( -0.98)/-0.5

= - 250.88/-0.5

S6 = 501.76

a28=58

step-by-step explanation:

a1=a1+(n-1)d

a28= 4+ (28-1)2

a28=4+(27)(2)

a28=4+54

a28=58

( - 4 , -7 )

all the lines must parallel  

step-by-step explanation:

coordinates of c = ( - 1 , 2 )

3 units left = ( -4 , 2 )

9 units down = ( - 4 , 11 )
