What is the midpoint of C(5,9) and D(17,29)?

(11, 19)

Step-by-step explanation:

Difference between x values: 17 - 5 = 12

Half 12 = 6

5 + 6 (halfway along line) = 11

Difference between y values: 29 - 9 = 20

Half 20 = 10

9 + 10 (halfway along line) = 19

The answer is (11, 19).

b. 6

step-by-step explanation:

we are given the table representing an exponential function.

we can see from the table that, as x is increasing, the value of y is increasing in the power of 6.

i.e. the following relation is obtained,

x = 1, y = 6

x = 2, y = 36 =

x = 3, y = 216 =

x = 4, y = 1296 =

x = 5, y = 7776 =

so, the geometric series obtained is .

thus, the common ratio is given by = = 6.

hence, the common ratio is 6.
