Answer:
4.2 meters
Step-by-step explanation:
The height that the lights will be put is 420 centimeters, and the question asks how many meters off the ground the lights need to be placed, so to solve the question we just need to convert 420 centimeters to meters.
We know that 1 meter is equal to 100 centimeters, so we can solve this using a rule of three:
100 centimeters -> 1 meter
420 centimeters -> X meters
100/420 = 1/X
X = 420/100 = 4.2 meters
The lights need to be placed on the pole at 4.2 meters off the ground.
Answer:
Switch x and y.
Step-by-step explanation:
Switch the x and y, so the equation would read as:
![x = \sqrt[3]{8y} +4](https://tex.z-dn.net/?f=x%20%3D%20%5Csqrt%5B3%5D%7B8y%7D%20%2B4)
Then solve for y.
![x = \sqrt[3]{8y} + 4\\\\\\x - 4 = \sqrt[3]{8y} \\\\\\(x-4)^{3} = 8y\\\\\\\\\\\frac{1}{8} (x-4)^{3}](https://tex.z-dn.net/?f=x%20%3D%20%5Csqrt%5B3%5D%7B8y%7D%20%2B%204%5C%5C%5C%5C%5C%5Cx%20-%204%20%3D%20%5Csqrt%5B3%5D%7B8y%7D%20%5C%5C%5C%5C%5C%5C%28x-4%29%5E%7B3%7D%20%3D%208y%5C%5C%5C%5C%5C%5C%5C%5C%5C%5C%5Cfrac%7B1%7D%7B8%7D%20%28x-4%29%5E%7B3%7D)
