Newton’s law of cooling states that the rate of cooling of an object is proportional to the temperature difference between the object and its surroundings. so the rate of cooling for a bottle of lemonade at a room temperature of 75°f which is placed into a refrigerator with temperature of 38°f can be modeled by dt/dt=k(t-38) where t(t) is the temperature of the lemonade after t minutes and t(0) = 75. after 30 minutes the lemonade has cooled to 60°f, so t(30) = 60.

to the nearest degree, what is the temperature of the lemonade after an additional 30 minutes?

What is x3+3x2−16x−48 divided by x−1?

Use the spider tool located on page 1 of this activity to draw a 12-pointed star for the new logo. (hint: if the spider rotates 360 degrees -- or 720 degrees or 1080 degrees -- she will be facing in the same direction in which she started. when the spider is done drawing, you want her to be facing in the same direction in which she started. she'll be making 12 rotations, all the same size, so each rotation must be some multiple of 360/12 = 30 degrees.) urgently. been stuck on this problem for around 45 minutes now.! it should be easy if you're smart enough
