Using Models Use the model given to answer the questions about the object or process being modeled. The gas mileage $M($ in milgal) of a car is modeled by $M=N / G,$ where $N$ is the number of miles driven and $G$ is the number of gallons of gas used. (a) Find the gas mileage $M$ for a car that drove 240 mi on 8 gal of gas. (b) $A$ car with a gas mileage $M=25$ mi/gal is driven 175 mi. How many gallons of gas are used?

Using Models Use the model given to answer the questions about the object or process being modeled. The portion of a floating iceberg that is below the water sur- face is much larger than the portion above the surface. The total volume $V$ of an iceberg is modeled by $$V=9.5 S$$ where $S$ is the volume showing above the surface. (a) Find the total volume of an iceberg if the volume show- ing above the surface is 4 $\mathrm{km}^{3}$ . (b) Find the volume showing above the surface for an ice- berg with total volume 19 $\mathrm{km}^{3}$ .

Using Models Use the model given to answer the questions about the object or process being modeled. The distance $d$ (in mi) driven by a car traveling at a speed of $v$ miles per hour for $t$ hours is given by $$d=v t$$ If the car is driven at 70 milh for 3.5 $\mathrm{h}$ , how far has it traveled?

trigonometry graphs and we're gonna look at vertical shifts. Now, here, we're gonna look at a couple different things. With this, we're gonna add one more element to our functions. And this time we're gonna add this, adding the K R K is going to determine our direction of going up or down. But K also tells us a midline and a midline is gonna basically is kind of thinking about drawing a new um X axis is kind of the best way I can describe it. It's not your X axis, but it's kind of drawing that new line to represent it on this vertical shift. Mhm and basically very similar to the horizontal. If you're K is greater than zero, you're gonna shift up. K is less, you're going to shift down, and it's gonna be all based on this midline, which is your K. So let's look at this one. Where have why? Why sign minus one now for this one, R K is gonna be negative one, which means we're gonna have a midline of negative one. So our X axis, of course, is obviously where x zero. So I'm gonna go ahead and draw a midline. We're at negative one. And this is a son. So I'm gonna go ahead and draw the sign graph out. This is what the sign graph looks like. And then if I go back animal kind of retouch this mid. Alright, so there's my midline. So basically, what I'm gonna do is I'm going to shift everything one down one basically where everything if it crosses the X axis, is now gonna be on the midline. So we do this color right here, so I'm gonna shift everything down those and so everything else will come down one as well. So now my new graph is going to be right here, So there's my vertical transformation.
