A tank containing 50 gallons of water is drained over the course of an hour. The
volume of water in gallons at various times
In minutes is given in the table below.

Time 0, 15, 30, 45, 60

volume 50, 23.63, 12.36, 2.75, 0

Use technology to find a quadratic function
that gives the volume as a function of time.

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,

sine

step-by-step explanation:

the 8 in 8,420 is in the thousands place so it's value is 8 thousand.

the 8 in 6,870 is in the hundreds place so it's value is 8 hundred.

divide 8000 by 800 to find the answer:

8000 / 800 = 10

the 8 in 8,420 is 10 times greater than the 8 in 6,870
