Answer
Find out the value of g(3) by using the function g(x) = x² + 2 given in the question .
To proof
The function given in the question is
g(x) = x² + 2
Take x = 3
put x = 3 in the g(x) = x² + 2
than it becomes
g(3) = 3² + 2
solving the above
we get
g(3) = 9 + 2
g(3) = 11
Thus g(3) = 11 and option (c) is correct .
Hence proved
Answer:
x = ±i8/7
Step-by-step explanation:
49x^2 +64 = 0
Subtract 64 from each side
49x^2 +64-64 = 0-64
49x^2 = -64
Divide by 49
49x^2/49 =-64 /49
x^2 = - 64/ 49
Take the square root of each side
sqrt(x^2) = ±sqrt(- 64/ 49)
x = ±sqrt(- 64/ 49)
We know sqrt( ab/c) = sqrt(a) sqrt(b)/sqrt(c)
x = ±sqrt(- 1) sqrt(64)/( 49)
We know that the sqrt(-1) = i
x = ±i8/7
Answer:
Step-by-step explanation:
Solving (a):
Solve for f(8)
We have:
Substitute 8 for x
Solve
Solving (b):
This is solved by:
So, we have:
Substitute:
Hence:
The correct answer is that it is 6% higher than the theoretical probability. You can find this because with 2 possible, equal outcomes, the theoretical probability is that you will get heads and tales 75 times. However, since we got heads 84 times in the experiment, we know that it is 6% more than 75.
