Meg kicks a soccer ball that follows the path given by the function h(t) - 16/486, where the height, h, of the ball in feet depends on time,
in seconds. Between which two times is the ball's height decreasing?
between 0 seconds and 1.5 seconds
B) between 1 second and 2 seconds
between 1 second and 3 seconds
D between 1.5 seconds and 3 seconds

the answer is 48m^2!

step-by-step explanation:

we can analyze the pattern at which the terms increase. let us denote , , , so that we can call

note the following:

the pattern: to get the next term value, we just add the next term number (e.g. 1st, 2nd, to the previous term value (term values are the given numbers in the question, 1, 3, 6, 10, 15,

from , to get to , we add

from , to get to , we add

etc.

we need to form a recursive formula, a formula that has the next term as a function of the previous term. so a possible recursive formula can be

, and for

answer: 0

step-by-step explanation: the positive, like 5, + its opposite, like -5 would be 0

5+(-5)=0, or 5-5=0
