Select the two values of x that are roots of this equation x^2-5x+2=0
Nataly [62]

The roots of the equation is x = 4.56 OR x = 0.44

<h3>Quadratic equation</h3>

From the question, we are to determine the roots of the given equation

The given equation is

x² -5x +2 = 0

Using the formula method,

x =\frac{-b \pm \sqrt{b^{2}-4ac } }{2a}

In the given equation,

a = 1, b = -5, c = 2

Putting the values into the formula,

x =\frac{-(-5) \pm \sqrt{(-5)^{2}-4(1)(2) } }{2(1)}

x =\frac{5 \pm \sqrt{25-8} }{2}

x =\frac{5 \pm \sqrt{17} }{2}

x =\frac{5 + \sqrt{17} }{2} OR x =\frac{5 - \sqrt{17} }{2}

x =\frac{5 + 4.12}{2} OR x =\frac{5 - 4.12}{2}

x =\frac{9.12}{2} OR x =\frac{0.88}{2}

x = 4.56 OR x = 0.44

Hence, the roots of the equation is x = 4.56 OR x = 0.44

Answer the questions <br><br> 1.find the value of x<br> 2.find m 3.finds
zloy xaker [14]

Answer:

x = 13°

Step-by-step explanation:

m<EGF + m< FGH = m<EGH

or, 3x+6+5x-7 = 103°

or, 8x-1 = 103°

or, 8x = 103°+1°

or, x = 104°/8

or, x = 13°

Now,

m<EGF = 3x+6

= 3×13+6

= 39+6

= 45

m<FGH = 5x-7

= 5×13-7

= 65-7

= 58

Data was collected on the number of pets and the height of a random group of students. Identify the correlation you would expect
Ipatiy [6.2K]
No correlation
A scatterplot is used to represent a correlation between two variables. There are two types of correlations: positive and negative. Variables that are positively correlated move in the same direction, while variables that are negatively correlated move in opposite directions.
