Choose all that give the correct explicit and recursive formula for the sequence. −4, −6, −8, −10, explicit: an = 2n − 2 recursive: an = a(n − 1) − 2 84, 71, 58, 45, explicit: an = −13n + 97 recursive: an = a(n − 1) − 13 19, 13, 7, 1, explicit: an = −6n + 25 recursive: an = a(n − 1) − 6 9, 17, 25, 33, explicit: an = 8n + 1 recursive: an = a(n − 1) − 8

the answer is a. q=6,r=6√2

step-by-step explanation:

secant-secant formula:

(whole secant) x (external part) =           (whole secant) x (external part)

(8+y-2) *8=                                           (y+4+6) *6

(y+6)*8 = (y+10) *6

distribute

8y+48 = 6y +60

subtract 6y from each side

2y +48 = 60

subtract 48 from each side

2y = 12

divide by 2

y = 6

sv =     (y+4+6)

sv   = 6+4+6

sv = 16
