Answer:
g( f(x) ) = 2x^2 + 11 (Answer choice B)
Step-by-step explanation:
g( f(x) ) involves using the function f(x) = x^2 + 6 as the input to g(x).
Here, g(x) = 2x - 1. Replace the x in g(x) by "f(x)" and the x in 2x - 1 by x^2 + 6. Then we have g( f(x) ) = 2[x^2 + 6] -1. This can be simplified, as follows:
= 2x^2 + 12 - 1, or 2x^2 + 11. This is answer choice B.
What is the centripetal force keeping the Earth in orbit?
I found how far the earth travels in one year (340,000,000), The Earths Tangential velocity (29814 m/s), and the centripetal acceleration of the earth (5.928e-3 m/s^2), but what is the centripetal force keeping the earth in orbit?
Answer:
small number is 14
Larger number is 31
Step-by-step explanation:
Let x = one number
Let y = the second number
x + y = 45
x = y - 17
Put y - 17 into the top equation for x
y - 17 + y = 45
2y - 17 = 45 Add 17 to both sides
2y = 45 + 17
2y = 62 Divide by 2
y = 62/2
y = 31

Answer:
61% of the time a person will wait at least 1.872 seconds before the wave crashes in.
Step-by-step explanation:
An uniform probability is a case of probability in which each outcome is equally as likely.
For this situation, we have a lower limit of the distribution that we call a and an upper limit that we call b.
The probability that we find a value X lower than x is given by the following formula.
Uniform distribution from 0 to 4.8 seconds.
This means that 
61% of the time a person will wait at least how long before the wave crashes in?
This is the 100 - 61 = 39% percentile, which is x for which 
. So
61% of the time a person will wait at least 1.872 seconds before the wave crashes in.
