D

Step-by-step explanation:

square the 16 and 4.2 and sun them up due to the pythagorean theorem (a^2+b^2=c^2)

get 273.64 and take the sqrt of that to find c.

get 16.54 and round to 17 :)

true

explanation:

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.
