The inverse function is f(x) =
You can find the inverse of any function by switching the f(x) value and the x value. Then solve for the new f(x) value. The result will be your inverse function. Below is the step-by-step process for solving this one.
f(x) = 2x + 1 ---> Switch the f(x) and x values
x = 2f(x) + 1 ---> Subtract 1 from both sides
x - 1 = 2f(x) ----> Divide each side by 2.
= f(x) ---> Switch the order so that it looks like a function.
f(x) =
And that would be your inverse function.
It is true that 5^2=25 but it is also true the -5^2=25. – 5 would also work.
Answer:
a) 74.69
b) 0.08% probability that on a given day, 51 radioactive atoms decayed.
Step-by-step explanation:
In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by the following formula:
In which
x is the number of sucesses
e = 2.71828 is the Euler number
is the mean in the given time interval.
a. Find the mean number of radioactive atoms that decayed in a day.
27,263 atoms in 365 days. The mean is
b. Find the probability that on a given day, 51 radioactive atoms decayed.
This is P(X = 51).
0.08% probability that on a given day, 51 radioactive atoms decayed.
Answer:
The answer will be ( x - 4 ) ( x^2 + 4 )
Answer:
C= 2π14.5
C= 91.1061869
91.1061869 X 7.5 = 683.296402
A of a circle = πr squared
as the are two circles to a cylinder 2πr squared
2 X π X 14.5 = 1321.03971
add together
1321.03971 + 683.296402 = 2004.33611 ft squared
