Question 12 Solve
The distance, s(t), in feet traveled by a freely falling object is given by the function s(t) = 162, where
t is time in seconds. Use this formula to find the time it would take for an object to fall to the
ground from a cliff that is 1024 feet high.

7 sec

64 sec

8 sec

9 sec

8 seconds

Step-by-step explanation:

The correct formula is

s(t) = 16t²

1024 = 16t²

Divide both sides by 16

64 = t^2

Take the square root of both sides

8 = t

8 seconds

arithmetic sequence

step-by-step explanation:

given that a sequence has terms as

19, 15, 11,

this is represented on a graph

the pattern indicates that the sequence is an arithmetic sequence with i term

a=19 and common difference d =-4

any general term

thus the sequence is reduced by 4 for each successive term starting from 1 and nth term is

24-5n.

first negative term would start after 5th term

5th term =24-25< 0

from 5th term onwards the sequence would be negative.

3/4 ÷ 3/4

step-by-step explanation:

basically divide any proper fraction with itself to fit the criteria.

so if we are using 3/4, then:

3/4 ÷ 3/4 = 1

so 1 is the quotient.

and the numerators for both these fractions is 3.   and if we divide the numerators:

3 ÷ 3 = 1

we see that quotient is equal to our original quotient as well.
