Brainliest and five stars to correct answer pls show work the position of an object at time t is given by s(t) = -9 - 3t. find the instantaneous velocity at t = 8 by finding the derivative.

Hello! There are a few ways to find the derivative. One famous formula is below:

Note, t = x = 8

To find the derivative of s(t) = -9 - 3t let insert it into our formula:

Insert x = 8

found it xd it ok yt

answer: - (a)

(b) 88 seats

step-by-step explanation:

given: in an auditorium, there are 22 seats in the first row and 28 seats in the second row.

thus first term=

second term=

the number of seats in a row continues to increase by 6 with each additional row.

⇒d= 6

a) given formula :

b)   let the number of seats (n) = 12

substitute n=12 in the explicit rule formed in (a)

∴there are 88 seats in 12 rows.
