Find the zero of the function.
f(x)= 4x^2– 12x+9
1 answer:
Answer:
The zero is x = 3/2 = 1.5
Step-by-step explanation:
We recognize that the trinomial 4 x^2 - 12 x + 9 is a perfect square trinomial, which comes from the following squared binomial:
(2 x - 3)^2
Therefore, the zeros are the x-values that verify the following:
(2 x - 3)^2= 0
that is (2 x - 3) = 0 and solving for "x":
2 x = 3
x = 3 / 2
x = 1.5

Answer: 2
Explanation:
y = 0.5x + 1
y = 0.5(2) + 1
y = 1 + 1
y = 2
We know that
the scale (cm/feet)-----------> 1/2
1 in-------------> 2.54 cm
x in---------------> 1 cm
X=1/2.54------> 0.3937 in
so
the new scale (in/feet)------------> 0.3937 in/ 2 feet-------> 0.1969 in/feet
the answer is
0.1969 in/feet
They gave the coordinates so you are going to use distance formula to find the MN.
