Y= F(x)=(-2) find f(x) when x is -3

Mathematics
1 answer:
Archy [21]3 years ago
5 0
F(x)= -2 means that with any value of x, f(x) will be the same and equal -2.
So, f(-3)=-2.

And also, f(-1)=f(4)= -2, and so on.

These tables represent an exponential function.Find the average rate of change for the interval from x=8 to x=9
GuDViN [60]

Answer:

Option D. 13122 is the answer.

Step-by-step explanation:

As we can see from the table having interval and average rate of change, figures under average rate of change are forming a geometric sequence.

Sequence is 2, 6, 18 , 54, 162, 486.

and we have to find the average rate of change from x = 8 to x = 9, means we have to find 9th term of the given sequence.

Now we know that explicit formula of the sequence can be written as T_{n}=ar^{n-1}

where Tn is the nth term of the sequence.

a = first term

r = common ratio

n = number of the term

Now from this explicit formula we can find the 9th term of the sequence.

From the given table

a = 2, r = 3, n = 9

T_{9}=2.3^{9-1}=2.3^{8}

T9 = 13122

Therefore Option D. 13122 will be the answer.

pogonyaev

Answer:

13.75

Step-by-step explanation:

The expected value of the hourly wage is the sum of the probabilities (percentage of time spent on each job) multiplied by the payoff (money earned) from each possible occurrence (job):

(0.6 × 11) + (0.25 × 19) + (0.15 × 16) = $13.75.
