If 2is the zero of the polynomial f(x)=x^2-8x+k then the value of k is

12

Step-by-step explanation:

zero of the polynomial is 2 ⇒ f(2) = 0

f(2) = 2² - 8 × 2 + k = 0

4 - 16 + k = 0

k = 12

answer: what

step-by-step 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.
