I WILL GIVE 1: AB + BC = AC, because 25 + 144 = 169
2: (AB)^2 + (BC) = (AC)^2, because 13^2 + 5^2 = 12^2
3: AB + BC = AC, because 13^2 + 5^2 = 12^2 4: (AB)^2 + (BC)^2 = (AC)^2, because 25 + 144 = 169

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.

the radius is 2 times the diameter.
