Acylindrical tank with height 7, radius 3, and weight 38 lbs is vertically submerged in water, with y(t) the height of the tank above the water. two forces act on the tank, the acceleration due to gravity, 32{ft}{s^2} acting in the opposite direction of y and the buoyancy force by archimedes principle. a. if water weighs 62.4{lbs}{ft^3} then the buoyancy force is b. therefore the differential equation modeling the forces on the tank is ''+=0

answer: domain and range mean all possible values of x and y that could be substituted to the inequality. a solution means all possible values that make the inequality statement true. so while the range is still all real numbers, the solution is the shaded area, for which y will always be greater than the line of the function.

step-by-step explanation:

from this example, we can see that subtracting with integers is the same as adding the opposite. we can solve using a number line or by using the saying "keep, change, change" to us solve. it is important to remember that we can subtract a negative and end up with a larger number than we started with.
