Answer:
18 meters by 9 meters (or 9 meters by 18 meters)
Step-by-step explanation:
lets say the dimensions are x and y. we have x*y=162, and 2x+2y=54. from the second equation we have x+y=27 so y=27-x. plug this into the first equation to get x(27-x)=162 or -x^2 + 27x = 162. x^2 - 27x + 162 = 0. simplify to get (x-18)(x-9)=0. so x=18 or x=9. when x=18, y=9, when x=9, y=18 so the dimensions are 18 by 9 meters
Answer:
The computer's initial price was $500.
Step-by-step explanation:
If you notice, at the top left of the graph, the y is 500 and the x is 0. The x-axis is also the timeline while the y-axis is the price line.

Answer:
58.74 cubic meters
Step-by-step explanation:
The function is actually 
Here x is the number of days and the corresponding value of "f(x)" would be the water REMAINING after x days.
Since, we want to figure out how much water (from 60 m^3) is remaining after 7 days, we simply have to plug in x = 7 into the function. Whatever number we get, is the AMOUNT OF WATER REMAINING AFTER 7 DAYS.
So,

Thus, the amount of water remaining in the pool after 7 days is 58.74 cubic meters
