Use the parabola tool to graph the quadratic function f(x)=2x^2−8x+2.
garik1379 [7]

Answer:

(0, 2) and (2, -6), among other points!

Step-by-step explanation:

If all you need is two points, choose two values for x and plug them into the formula for the function.

x=0 \Rightarrow 2(0)^2-8(0)+2=2  so the point (0, 2) is on the graph.

x=2 \Rightarrow 2(2)^2-8(2)+2=-6  so the point (2, -6) is on the graph.

Given: 315/1575. Write the prime fractorization of the numerator and the denominator, then write the fraction in lowest terms.
Ne4ueva [31]
The prime factorization of the numerator, 315, is 5 x 3 x 3 x 7. That of the denominator, 1575 is 5 x 5 x 3 x 3 x 7. To convert the fraction to its lowest form, cancel all the factors that appear to both the numerator and denominator. We will be left with 1/5.

max2010maxim [7]

Answer:

5901

Step-by-step explanation:

The margin of error is the critical value times the standard error.

ME = CV × SE

For α = 0.05, the critical value is z = 1.96.

The standard error of a proportion is √(pq/n).  Given p = 0.04, then q = 1−p = 0.96.

The margin of error is 0.5% or 0.005.

Plugging in:

0.005 = 1.96 √(0.04 × 0.96 / n)

n ≈ 5901
