So here we're dealing with changing dimensions of a rectangle, so you know that a rectangle is going to have a length times a with okay. Section 3.8 looking at problem number 21. The perimeter is actually not changing at all at that point, and then the area is increasing areas getting bigger, the perimeter staying the same at that incident time and the diagonals are decreasing. So the question in says which ones? Air decreasing, which are increasing in this particular case. These year, I'm gonna have 1/13 and then multiplied by and then minus 24 plus 10 So that's going to be minus 14/13 and that's gonna be in centimetres per second. And I'm actually gonna cancel these twos right now, because I can. So this right here is actually gonna be the spirit of 169. So what we're gonna end up with and I'll just go to the next page to finish this, um is you'll have Wallace scored 144 plus five Squared is 25. L is 12 at this time, so 12 squared and w is five. So if we do the derivative of that e d by d t then is gonna be one over to room Anil squared plus times you l d l binding t and then plus two w he w by all right.Īnd then I just got my numbers in d D by D. So for part c, we'll do it different color distance for the diagonals is gonna be the spirit of al spared plus u squared. I think you'll probably notice that is square root of l squared plus w squared. Or if you go back here again, we have minus two, and that's to and the perimeter again is L l and W W So then it asks us the third thing and asked us about our these diagonals. All right, so that's gonna be two times minus two plus two times to what we're actually gonna end up with is zero centimeters per second. So dp by t t is gonna be two times d l buddy t plus two times d w by the tea. Okay, So for part B, the political is going to be two l's and to W's, right, because it's just the length around the outside. The areas increasing it 14 centimeter 20 and it asks about the perimeter. The fact is that 14 and it's centimeter squared per second. Nobody which is minus two and you end up with 24 minus in. Then we're gonna take W, which is five and well played by you. So the area is length times width, which means D A by T t is gonna be L d w by the tea plus W d L by d. It's his DW bloody t is increasing at two centimeters per second and then it says at the point we're talking, the length is 12 centimeters and the wind is five centimeters.Īt the instant in time that we're talking to find the rates of chains of First of all, part A is the area. Buddy T Surrey is negative because decreasing and its two centimeters per second and in the width is changing as well. Ah, the rate at which the length is changing its is decreasing. Investigators noticed that the imprints on the counterfeit pills were made “at an angle” and not as deep as the manufacturer’s pills.This question gives a rectangle, and it tells us that the length and the width are changing. On the other side, the pills are imprinted with the numbers “10/325,” usually an indication of medication dosage. “Percocet” had been stamped in capital letters on one side of the pills, the Bibb County Sheriff’s Office said Wednesday. Navicent Health was one of three hospitals in Georgia known to have received the overdose patients. Christopher Hendry, chief medical officer of Navicent Health, said Tuesday. Those who overdosed thought they were swallowing Percocet, but the overdose symptoms were “much more severe in onset,” Dr. The second opioid found was a known synthetic drug, Miles said, but its name is being withheld until the full analysis of both drugs is complete. Further testing is required to verify the identity of the new drug, the bureau said. Overdose cluster in Georgia linked to mystery pillįentanyl is 50 to 100 times more potent than the drug morphine, and experts say some fentanyl-like molecules can be far more potent. Then, they may be packed into pill presses in the United States, she said. Miles said synthetic drugs like this one are coming in from overseas, where fentanyl molecules are altered slightly in an effort to skirt US laws. The pills were made to resemble the prescription painkiller Percocet and sold on the street, according to state officials. The unknown opioid is a modified type of fentanyl that the GBI Crime Lab had never seen, the bureau said. “We’re essentially working it up from scratch.” “The fact that the GBI Crime Lab has never seen it is a very bold statement,” said Nelly Miles, director of the GBI Office of Public Affairs and a forensic chemist by training. One of the drugs is still unidentified and may be a new compound, according to a GBI representative. Two synthetic opioids have been found in fake prescription pills suspected to have caused a cluster of overdoses this week in Georgia, including four deaths, according to a statement from the Georgia Bureau of Investigation.
