Answer:
Step-by-step explanation:
As stated in the question, the probability to toss a coin and turn up heads in the first try is 
, in the second is 
, in the third is 
and so on. Then, P(C) is given by the next sum:
This is a geometric series with factor . Then is convergent to 
. With this we have proved that P(C)=1.
Now, observe that
Then
and
Answer: rational
Step-by-step explanation: 7 has an answer example 7+1 is 8 irrational are the ones that dont get an answer like root numbers
The answer would be about 98 hamburgers.
This is because you would have to divide 393 by 2 to get 196.5.
Since the number of cheeseburgers is doubled divide 196.5 by 2 to get 98.25.
Add 98.25 to 196.5 and get 294.75.
Subtract.
Hello!
The discriminant of quadratic functions is: b² - 4ac. Since the equation is in standard form, which is Ax² + Bx + C = 0 , we can substitute those values into our discriminant and simplify.
The value of the discriminant will tell us how many solutions there are to the given quadratic equation.
A positive discriminant will have two real solutions.
A discriminant of zero will have one real solution.
A negative discriminant will no real solutions.
1. Substitute, a = 16, b = 8, c = 1.
8² - 4(16)(1)
64 - 4(16)(1)
64 - 64(1)
64 - 64
0
Since the discriminant is zero, the answer is choice A, double root, because since it is raised to the power of 2, it must has two roots, but in this case, both of the roots the same x-values.
