Atank contains 280 gallons of water and 10 oz of salt. water containing a salt concentration of -(1 + =sin t) oz/gal flows into the tank at a rate of 3 gal/min, and the mixture in the tank flows out at the same rate. the long-time behavior of the solution is an oscillation about a certain constant level. what is this level? what is the amplitude of the oscillation? round the values to two decimal places. oscillation about a level = oz. amplitude of the oscillation =

b is 38 degrees.

a is 52 degrees.

this is because if b is 38 and a is 14 degrees more than b than 38+14=52 and 52+38=90 degrees. hope this .

answer: when you burn wood, the carbon reacts with the oxygen in the air to create ash and smoke. that is a permanent change you cannot undo that.

step-by-step explanation:

two pairs of adjacent sides are of equal length. this implies that one diagonal divides the kite into congruent triangles, and so the angles between the two pairs of equal sides are equal in measure. it also implies that the diagonals are perpendicular.

-60.75

step-by-step explanation:

just add the numbers then put the negative sign on it
