So this is another slightly worried you're related rates. Problem. Um, so let's identify relations in question were told that the crime, right, see, which is the object of consideration in this question equals 1 10 off the temperature of minus 60 squared plus 100. And this is in a town of 100,000 people. But that doesn't matter. What does matter is that the temperature we are interested in is 76 degrees fire. It hides and up. The temperature is increasing with eight Greece per day. And the question is, of course, at what grade is the crime rate increasing? So, um, we have everything we need for a related rates problem. So we can start by differentiating differentiating this relation. You find that the rate of change and crime rates equals, um, one 10 times chain rule. So too, T minus 60 multiplies by Petey G plus nothing because 100. It's constant tire. So, um, well, we can simplify this a little bit. We can oh, catch these constants or collapses Constance into 11 50. Um, but that's our differentiation stuff. Then you substitution step. In this case, the CVT equals 1/5 76 minus 60 multiplied by eight and then sold. So in this case, the equation solves the real just compute in this case, so interested in D C B T. And it's isolated on one side of the equation. So 76 minus 60 is 16 so we have 16 times eight. Fight it by five, um, which isn't actually an insecure selection still stuck into a calculator. You bet 16 times a divided by five equals 25 0.6, so the crime rate is going up by 25.6 incidents per day.
