Answer:
I got it.
Step-by-step explanation:
-12a - (-15b) + (-3c)
Answer: three pieces.
The piece of wood is 6/8 inches long - this fraction can be simplified to 3/4 by dividing both the numerator and denominator by 2.
Thus, he cuts a piece of wood that is 3/4 inches long into 1/4 inch pieces.
1 goes into 3 three times, so the piece of wood can be cut into three 1/4-inch pieces.
Answer:
The answer is $10.80
Step-by-step explanation:
It goes up $0.70 every mile and the flat fee is $3.10.
The equation 3.1 + 0.7(x) when x is the number of miles traveled.
Substitute 11 for x and get 3.1 + 0.7(11).
The answer is $10.80
Use these equations when converting polar equations to parametric equations:
![x=r\cos\theta](https://tex.z-dn.net/?f=x%3Dr%5Ccos%5Ctheta)
![y=r\sin\theta](https://tex.z-dn.net/?f=y%3Dr%5Csin%5Ctheta)
We know that
, so substitute that into both equations for x and y.
![x=5\theta\cos\theta](https://tex.z-dn.net/?f=x%3D5%5Ctheta%5Ccos%5Ctheta)
![y=5\theta\sin\theta](https://tex.z-dn.net/?f=y%3D5%5Ctheta%5Csin%5Ctheta)
Now, replace
with any variable that you want to represent the parametric equations in. I'll use the standard variable, ![t](https://tex.z-dn.net/?f=t)
![x=5t\cos t](https://tex.z-dn.net/?f=x%3D5t%5Ccos%20t)
![y=5t\sin t](https://tex.z-dn.net/?f=y%3D5t%5Csin%20t)
Thus,
represented in parametric form is:
![(x,y)=(5t\cos t, 5t \sin t)](https://tex.z-dn.net/?f=%28x%2Cy%29%3D%285t%5Ccos%20t%2C%205t%20%5Csin%20t%29)
