Answer:

The average rate of change of the function in this interval is of 18.

Step-by-step explanation:

The average rate of change of a function f(x) in an interval from a to b is given by:

A = \frac{f(b) - f(a)}{b - a}

In this question:

f(x) = x^2 + 6x

Where x goes from 5 to 7.

This means that b = 7, a = 5. So

f(7) = 7^2 + 6(7) = 49 + 42 = 91

f(5) = 5^2 + 6(5) = 25 + 30 = 55

The rate of change is:

A = \frac{f(7) - f(5)}{7 - 5} = \frac{91 - 55}{2} = 18

The average rate of change of the function in this interval is of 18.

What is the probability of losing 6 times in a row playing Heads or Tails flipping a coin?
slava [35]
The probability of losing per flip is 1/2. Multiply 1/2 by itself 6 times since the condition is asking for the probability for the person to lose 6 times in a row. 1/2 * 1/2 * 1/2 * 1/2 * 1/2 * 1/2 = 1/64. The answer is 1/64.
