The model $L=4 S$ gives the total number of legs that $S$ sheep have. Using this model, we find that 12 sheep have $L=$ __________ legs.

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 volume $V$ of a cylindrical can is modeled by the formula $$V=\pi r^{2} h$$ where $r$ is the radius and $h$ is the height of the can. Find the volume of a can with radius 3 in. and height 5 in.

postseason function. Now we practice sine function, and a cosign function is done very similar to a sine function. Um, we're gonna start off the same way. First thing we're gonna do is we're gonna find the X intercept. Now, when you're talking about cosign, you're actually gonna be looking, um, a little differently because now what you're gonna be looking at is you're gonna be looking at that 90 degrees in to 70 degrees. So when you're looking at, you want to see where the cosign is Zero. Because remember that Kasan is your ex over our So you wanna get that tow where your ex is actually going to be zero over our. So the two points that that happens at is means it's gonna be basically you're looking at the y intercept. So those two points are gonna be at 0 90 they're gonna be at nine degree angles and at 270 degree angle. So what you're looking at is you've got a 90 zero and 2 70 zero. So those were gonna be my ex intercepts. From there, I'm gonna look at my maximum and minimum again. This is where you want to get again. Remember, Cosign, you're looking at a X over our. So you want to see where the maximum is one or the minimum would be negative one. Well, it's that positive one at zero degrees and at 360 degrees. Is that negative? One at 180 degrees. So, at this point, that means that right there is gonna be my each unit on this, uh, coordinate. Griffin is gonna be 1/4 so that's gonna be one. There's my minimum. And here is my maximum. So a co sign graph is gonna look similar to this right here. And the pattern would actually just keep going, so it would continue those lips.
