Answer:
$936.94
Step-by-step explanation:
Remember, that because you paid $2,175 up front (down payment), you can borrow $2,175 less from the bank to purchase the car. So first step: Take new car price of $19,725.00 and multiply it by the sales tax percentage ($19,725 * 0.0475) to get $936.94 of tax.
(-2,-4)
Due to the intervals between the points this would be the answer because the pattern shown.
Answer:
y = -2x + 3
Step-by-step explanation:
4x + 2y = 6
⇔ 2y = ![\frac{6 - 4x}{2} = \frac{6}{2} - \frac{4x}{2} = 3 - 2x = -2x + 3](https://tex.z-dn.net/?f=%5Cfrac%7B6%20-%204x%7D%7B2%7D%20%3D%20%5Cfrac%7B6%7D%7B2%7D%20-%20%5Cfrac%7B4x%7D%7B2%7D%20%3D%203%20-%202x%20%3D%20-2x%20%2B%203)
Answer:
![cos(C) =\frac{40}{41}\\\\cos(C)=0.976](https://tex.z-dn.net/?f=cos%28C%29%20%3D%5Cfrac%7B40%7D%7B41%7D%5C%5C%5C%5Ccos%28C%29%3D0.976)
Step-by-step explanation:
To find the
we must use the cosine theorem.
The cosine theorem says that:
![c^2 = a^2 +b^2 -2abcos(C)](https://tex.z-dn.net/?f=c%5E2%20%3D%20a%5E2%20%2Bb%5E2%20-2abcos%28C%29)
In this case:
![c=AB = 9](https://tex.z-dn.net/?f=c%3DAB%20%3D%209)
![b=CA = 41](https://tex.z-dn.net/?f=b%3DCA%20%3D%2041)
![a=BC = 40](https://tex.z-dn.net/?f=a%3DBC%20%3D%2040)
So
![9^2 = 40^2 +41^2 -2(40)*(41)cos(C)](https://tex.z-dn.net/?f=9%5E2%20%3D%2040%5E2%20%2B41%5E2%20-2%2840%29%2A%2841%29cos%28C%29)
![9^2- 40^2- 41^2 =-2(40)*(41)cos(C)](https://tex.z-dn.net/?f=9%5E2-%2040%5E2-%2041%5E2%20%3D-2%2840%29%2A%2841%29cos%28C%29)
![cos(C) = -\frac{9^2- 40^2- 41^2}{2(40)*(41)}](https://tex.z-dn.net/?f=cos%28C%29%20%3D%20-%5Cfrac%7B9%5E2-%2040%5E2-%2041%5E2%7D%7B2%2840%29%2A%2841%29%7D)
![cos(C) =\frac{40}{41}\\\\cos(C)=0.976](https://tex.z-dn.net/?f=cos%28C%29%20%3D%5Cfrac%7B40%7D%7B41%7D%5C%5C%5C%5Ccos%28C%29%3D0.976)
