Answer: -63

Step-by-Step Solution:

=> an = 3 - 6(n - 1)

Hence,
=> a = 3
=> d = -6
=> n = 12

Therefore,
an = 3 - 6(n - 1)
a12 = 3 - 6(12 - 1)
a12 = 3 - 6(11)
a12 = 3 - 66
=> a12 = -63

A ball is thrown in the air from a ledge. Its height in feet is represented by f(x) = –16(x2 – 5x – 6), where x is the number of
Oduvanchick [21]

The ball takes 6 seconds to reach the ground.

<u><em>Explanation</em></u>

Height of the ball after x seconds is represented by....

f(x)= -16(x^2 -5x-6)

The height of the ball is 0 feet when it hits the ground. So, for finding the number of second the ball takes to reach the ground, <u>we will just plug f(x)=0 into the above equation and then solve for x.</u>

Thus...

0=-16(x^2-5x-6)\\ \\ x^2-5x-6=0\\ \\ (x-6)(x+1)=0

Using zero-product property....

x-6=0\\ x=6

and

x+1=0\\ x=-1 (Negative value is ignored as time can't be negative)

So, the ball takes 6 seconds to reach the ground.
