The arithmetic sequence a_ia
i

a, start subscript, i, end subscript is defined by the formula:
a_1 = 5a
1

=5a, start subscript, 1, end subscript, equals, 5
a_i = a_{i - 1} + 2a
i

=a
i−1

+2a, start subscript, i, end subscript, equals, a, start subscript, i, minus, 1, end subscript, plus, 2
Find the sum of the first 700700700 terms in the sequence.

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.

solving with completing the square

the answer is d

step-by-step explanation:

y+3=-4(x-2)

y+3=-4x+8

  -3         -3  

y=-4x+5

10.416 m/s

step-by-step explantion:

distance=100m

time= 9.6s

average speed=100/9.6

=10.416 m/s

on monday rodney ate 1/4th of the sandwich = 3/12

on tuesday he ate 1/3rd of the sandwich = 4/12

therefore in total he has eaten = 3/12 + 4/12 = 7/12

thus we can say that he has eaten 7/12 of the sandwich on monday and tuesday alltogether.

happy to
