The table shows the amount of water left in a pool over time as it is being drained. the table represents a linear function. time (h) water (gal) 0 | 18,500 1 | 17,000 2 | 15,500 3 | 14,000 what does the initial value mean for this function? after 3 hours, 14,000 gallons of water remain in the pool. after 2 hours, 15,500 gallons of water have been drained from the pool. the pool contains 18,500 gallons of water before it is drained. water drains from the pool at a rate of 1500 gallons each hour.

C. The pool contains 18,500 gallons of water before it is drained.

Step-by-step explanation:

The table shows the amount of water left in a pool, in gallons, over time, in hours, as it is being drained.

Time (h)Water (gal)

   0            18,500

   1             17,000

   2            15,500

   3            14,000

This table represents a linear function.

The initial value of the table is,

As here, time is 0 hours i.e at starting of the experiment, the water in the tank was 18,500 gallons.

Therefore, the initial value represents the amount of water before it is drained.

a4 - 3a2 - 1

step-by-step explanation:

step   1   :

equation at the end of step   1   :

  ((a4) -   3a2) -   1

step   2   :

trying to factor by splitting the middle term

2.1     factoring   a4-3a2-1  

the first term is,   a4   its coefficient is   1 .

the middle term is,   -3a2   its coefficient is   -3 .

the last term, "the constant", is   -1
