The formula for the volume of a pyramid is:
V = (l * w * h) / 3
knowing the formula we can replace the letters with the values we know:
v = 162
h = 6
since they told us the pyramid is square, we know that both L and W would be the same, so now we CAN SAY L *W = L^2 and solve for that:
162 = (l^2 * 6) / 3
multiply both sides by 3
486 = l^2 * 6
divide both sides by 6:
81 = l^2
l = sqrt(81)
l = 9 feet
Your Answer is correct, because for every rate of change the x-value (-1) is decreasing, and the rate of change f(x)-value (-3) is also decreasing. This gives you a -1/-3 rate of change (slope). Two negatives make a positive therefore the is at a constant rate of change (slope) of 1/3.
Keep in mind unfortunately I am not 100% sure, but this is what I think. Hope this helps a little!
Answer:
rs6657
Step-by-step explanation:
You can learn certain statistics with it or you can learn how to do things with it such as a calculator
Change in y = -200 meters
change in x = 400,000 meters
slope = change in y / change in x = -200/400,000 = -1/2,000 meters
