What is the zero of the function f(x)=1/8x^2-x+2

x = 4  

Step-by-step explanation:

ƒ(x) = ⅛x² - x + 2 = 0

        x² - 8x + 16 = 0

We must find two numbers whose product is 16 and whose sum is -8.

A little trial and error gives us -4 and -4. We can factor the expression as

(x - 4)(x - 4) = 0 or

      (x - 4)² = 0

         x - 4 = 0

              x = 4

The zero of the function is x = 4.

The graph of ƒ(x) just touches the x-axis at (4, 0).  

blue marble is 15 times out of 50 = 15/50 reduces to 3/10

landing on tails is 24 out of 50 = 24/50 reduces to 12/25

to find the probability of both multiply together:

3/10 x 12/25 = 3 x 12 / 10 x 25 = 36/250

if you multiplied the numerator and denominator by 10 you get 360/2500.

the answer is 360/2500

the answer is 175.4379
