What is the recursive formula for the geometric sequence with this explicit formula? an=6*(-1/4)^(n-1)

A

Step-by-step explanation:

The explicit formula for a geometric sequence is

= a₁

where a₁ is the first term and r the common ratio

Given the explicit formula

= 6

where a₁ = 6 and r = -

A recursive formula allows any term in the sequence to be found by multiplying the previous term by r , thus

= (- with a₁ = 6 → A

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571
