Aking size waterbed has the following dimensions 72 in. x 84 in. x 9.5in. it takes 240.7 gallons of water to fill it, which would weigh 2071 pounds. what is the weight of a cubic foot of water?

Solution :

Given, A King Size waterbed has the following dimensions 72 in. x 84 in. x 9.5in. It takes 240.7 gallons of water to fill it, which would weigh 2071 pounds.

Volume of the King Size Waterbed, V = length X width X height

We know that,

Weight of  33.25 cubic foot water = 2071 pounds

Weight of  water in 1 cubic foot water =

Hence, Water weighs 62.29 pounds per cubic foot.

1696 hundred thousand

step-by-step explanation:

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.
