Answer:

The answer to your question is    y = 2.^{x} + 5

Step-by-step explanation:

Because of the distribution of the points, we conclude that it is an exponential function so we discard the third option (it's a linear function) and the fourth option (it's a quadratic function)

- To solve this problem, evaluate functions 1 and 2 using the x-coordinates and compare the results with the graph

                       y = 2.^{x} + 5                              y = 4.^{x} + 8

1                       y = 2 + 5 = 7                           y = 12

3                      y = 8 + 7 = 15                         y = 21 + 8 = 29

5                      y = 32 + 7 = 39                      y = 1024 + 8 = 1032

7                      y = 128 + 7 = 135                    y = 16384 + 8 = 16392

9                      y = 512 + 7 = 512                    y = 262144 + 8 = 262152

11                      y = 2048 + 7 = 2055             y = 4194312 + 8 = 4194320

13                     y = 8192 + 7 = 8199                y = 67108864 + 8 = 67108872

15                     y = 32768 + 7 =  32775         y = 1073741832 + 8 = 1073741840

Comparing the result with the graph, we conclude that the answer is the first choice.

Find the exponential function that passes through the points (2,80) and (5,5120)​
juin [17]

Answer:

  y = 5·4^x

Step-by-step explanation:

If you have two points, (x1, y1) and (x2, y2), whose relationship can be described by the exponential function ...

  y = a·b^x

you can find the values of 'a' and 'b' as follows.

Substitute the given points:

  y1 = a·b^(x1)

  y2 = a·b^(x1)

Divide the second equation by the first:

  y2/y1 = ((ab^(x2))/(ab^(x1)) = b^(x2 -x1)

Take the inverse power (root):

  (y2/y1)^(1/(x2 -x1) = b

Use this value of 'b' to find 'a'. Here, we have solved the first equation for 'a'.

  a = y1/(b^(x1))

In summary:

  • b = (y2/y1)^(1/(x2 -x1))
  • a = y1·b^(-x1)

__

For the problem at hand, (x1, y1) = (2, 80) and (x2, y2) = (5, 5120).

  b = (5120/80)^(1/(5-2)) = ∛64 = 4

  a = 80·4^(-2) = 80/16 = 5

The exponential function is ...

  y = 5·4^x

A bag contains three marbles, eight blue marbles and nine red marbles. If the marbles are picked at random, what is the probabil
Phoenix [80]

The probability of obtaining two blue marbles without replacement is equal to 0.15.

We are given that:

The number of yellow marbles = 3

Number of red marbles = 9

Number of Blue marbles = 8

Total marbles = 3 + 9 + 8

Total marbles = 20

Now, we have to calculate the probability of obtaining two blue marbles without replacement.

The probability will be:

P( obtaining two blue marbles without replacement )  = 8 / 20 × 7 / 19

P( obtaining two blue marbles without replacement )  = 56 / 380

P( obtaining two blue marbles without replacement )  = 0.15

Therefore, the probability of obtaining two blue marbles without replacement is equal to 0.15.
