Answer:
d = -3
Step-by-step explanation:
Given the equation:
Solve for d:
Take both sides cube root we have;
![d =\sqrt[3]{-27}](https://tex.z-dn.net/?f=d%20%3D%5Csqrt%5B3%5D%7B-27%7D)
We can write 27 as:
then;
![d = \sqrt[3]{-3^3}](https://tex.z-dn.net/?f=d%20%3D%20%5Csqrt%5B3%5D%7B-3%5E3%7D)
Using the rules:
![\sqrt[n]{a^n} = a](https://tex.z-dn.net/?f=%5Csqrt%5Bn%5D%7Ba%5En%7D%20%3D%20a)
![\sqrt[3]{-1} = -1](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B-1%7D%20%3D%20-1)
then;
![d = -\sqrt[3]{3^3} = -3](https://tex.z-dn.net/?f=d%20%3D%20-%5Csqrt%5B3%5D%7B3%5E3%7D%20%3D%20-3)
therefore, the unknown variable d is, -3
Answer:
(-2,7) those are the coordinate. in which he will land
For number 3 the answer would be 6. That would be the answer for n.
For number 4 the answer would be -6. That would be the answer for n.
Answer:
The correct answer is C. $28,200.
Step-by-step explanation:
Given that James saw a truck at the dealership for $ 28,000 base price, $ 1,300 premium interior, $ 1,200 navigation touch-screen, and $ 1,700 smart traffic sensors, if his current vehicle is worth $ 5,000 and he's offered a 60% trade-in rate, to determine what is the total cost of the car after the $ 1,000 destination fee, the following calculation must be made:
28,000 + 1,300 + 1,200 + 1,700 - (5,000 x 60/100) = X
32,200 - (5,000 x 0.6) = X
32,200 - 3,000 = X
29,200 = X
29,200 - 1,000 = 28,200
Therefore, the total cost of the car after the $ 1,000 destination fee is $ 28,200.
