Answer:
A) f^-1(x)=(x-8)^3+2
Step-by-step explanation:
To find the function inverse, switch the x with y and solve for y.
![y=\sqrt[3]{x-2}+8 \\\\x=\sqrt[3]{y-2}+8\\\\(x-8)^3 = y-2\\\\ (x-8)^3 + 2 = y](https://tex.z-dn.net/?f=y%3D%5Csqrt%5B3%5D%7Bx-2%7D%2B8%20%5C%5C%5C%5Cx%3D%5Csqrt%5B3%5D%7By-2%7D%2B8%5C%5C%5C%5C%28x-8%29%5E3%20%3D%20y-2%5C%5C%5C%5C%20%28x-8%29%5E3%20%2B%202%20%3D%20y)
Answer:
Though one 1,320-foot tower is as long as 8 165-foot towers, that ... Managing wait time while people are loaded into its 16 cars will be ... You want a 3:2 ratio of ride time to load time.
The formula to find speed is distance divided by time or s = d / t. With this in mind, let's plug in some numbers into the equation.
Since they're asking for meters per second, multiply 60 seconds by 2 minutes:
60 * 2 = 120
Now add that to 56.35 (the amount of seconds we already know):
120 + 56.35 = 176.35
So, now that we know how many seconds they ran in total, divide the distance (1600) by the time (176.35):
1600/176.35 = 9.072866...
Round 9.072866... to the nearest hundredth, which is 9.07. And there's you're answer! They ran about 9.07 meters per second :)
Answer:
The highway fence cost $600.
Step-by-step explanation:
Since the highway fence is twice as cost as the one of the other 4 sides, this means that the highway fence = 2 normal fence.
Therefore, we use
$1800 / highway fence(2 normal fence) + 4 normal fence
$1800 / (2 + 4) = $300
This means that every normal fence cost $300.
Which then we get the highway fence is $600 because it costs double of the normal fence.
