Find the possible value or values of z in the quadratic equation z2 – 4z + 4 = 0. a. z = 2√ 2 + 2, z = −√ 2 + 2 b. z = 2 c. z =√ 2 + 2, z = −√ 2 + 2 d. z = 10, z = 6

There are 12 boy and13 girls in a class. if the teacher randomly chooses a student’s name out of a hat what is the probability it will be a girl

0if x and y vary inversely and y=6 as x=7, what is the constant of variation?

A. plot the data for the functions f(x) and g(x) on a grid and connect the points. x -2 -1 0 1 2 f(x) 1/9 1/3 1 3 9 x -2 -1 0 1 2 g(x) -4 -2 0 2 4 b. which function could be described as exponential and which as linear? explain. c. if the functions continue with the same pattern, will the function values ever be equal? if so, give estimates for the value of x that will make the function values equals. if not, explain why the function values will never be equal.
