Step-by-step explanation:

As it is a second order equation, it means that it has two possible answers and they are [tex]x_1[/tex] and [tex]x_2[/tex].

The famous quadratic formula for solving any second order equation is the following:

[tex]x_{1} = \frac{-b + \sqrt{b^2 - 4 ac}}{2a}\\x_{2}=\frac{-b - \sqrt{b^2 - 4 ac}}{2a}[/tex]

Where a is the coefficient of [tex]x^2[/tex], b is the coefficient of x, and c is the free term. In other words,

[tex]a = 3\\b=4\\c=-2[/tex]

as the equation should be in the following form:

[tex]a x^2 + bx+c = 0[/tex]

Therefore the possible answer should be the following,

[tex]\frac{-4 + \sqrt{4^2 - 4*3*(-2)}}{2*3}=\frac{-4 +\sqrt{16 + 24}}{6} =\frac{-4 + \sqrt{40}}{6}=\\ \frac{-4 + \sqrt{4*10}}{6} = \frac{-4 + 2\sqrt{10}}{6}[/tex][tex]\frac{2*(-2 + \sqrt{10})}{2*3} = \frac{-2 + \sqrt{10}}{3}[/tex]

by dividing the numerator and denominator by 2, we can deduce the following,

A quadrilateral has two angles that measure 200° and 110°. The other two angles are in a ratio of 2:3. What are the measures of those two angles?

Answers

Answer:

20° and 30°

Step-by-step explanation:

the sum of the 4 angles in a quadrilateral = 360°

given 2 angles are 200° and 110° , then remaining 2 angles sum to

360° - 200° - 110° = 360° - 310° = 50°

sum the parts of the ratio, 2 + 3 = 5 parts , then

1 part = 50° ÷ 5 = 10° , so

2 parts = 2 × 10° = 20°

3 parts = 3 × 10° = 30°

the two angles are 20° and 30°

Answers

An event that may occur in the game is you roll a  and get a tail.

The probability that he will roll a 5 and get a head is 1 / 12.

What is the probability?

Probability determines the chances that an event would happen. The probability the event occurs is 1 and the probability that the event does not occur is 0.

The probability that he will roll a 5 and get a head = (Number of sides with a 5 / number of sides in a cube) x (number of sides with a head / number of sides in a coin)

1/6 x 1/2 =  1 / 12.

Step-by-step explanation:

Given that XW bisects AXZ, what theorem or theorems could be used to justify that W is equidistant from the two outside rays?

Answers

Answer:

  HA congruence postulate

Step-by-step explanation:

In order to show W is equidistant from A and Z, we must demonstrate that WA ≅ WZ. The HA congruence postulate can be used for that purpose.

__

proof

WX bisects AXZ, so ∠WXA≅∠WXZ by the definition of an angle bisector. By the reflexive property of congruence, WX≅WX. The angles at A and Z are given as right angles.

So, we have triangles WAX and WZX that are right triangles with congruent hypotenuse and corresponding angle. These are the preconditions for the application of the HA congruence postulate. That postulate says the triangles WAX and WZX are congruent, so ...

WA ≅ WZ by CPCTC. Hence W is equidistant from the outside rays.

__

Additional comment

The definition of distance from a point to a line is the perpendicular distance from the point to the line. In this geometry, the perpendicular distances from W to the outside rays are the lengths of segments WA and WZ. That is why we need to show those lengths are the same.

V = 1872π

Volume of Cylinder B is;

V = π × 8² × 16

V = 1024π

After pumping, volume in container A will be;

V_new = 1872π - 1024π

V_new = 848π

Percentage is;

848π/1872π * 100% = 45.3%

Answer: It should look something like this.

Step-by-step explanation:

The graph of f(x) = (x + 3)(x - 2) is a parabolic function that is the product of two linear factors, (x + 3) and (x - 2).

The graph is given below.

What is a function?

A function has an input and an output.

A function can be one-to-one or onto one.

It simply indicated the relationships between the input and the output.

Example:

f(x) = 2x + 1

f(1) = 2 + 1 = 3

f(2) = 2 x 2 + 1 = 4 + 1 = 5

The outputs of the functions are 3 and 5

The inputs of the function are 1 and 2.

We have,

To understand the graph, we can begin by considering the x-intercepts, which are the points where the graph crosses the x-axis.

These occur where the value of f(x) is zero, which happens when either

x + 3 = 0 or x - 2 = 0.

So the x-intercepts are x = -3 and x = 2.

Next, we can consider the leading coefficient, which is 1 in this case.

Since the leading coefficient is positive, the parabola opens upward.

We can also find the vertex of the parabola by completing the square.

We have:

f(x) = x² + x(-2 + 3) - 2(-3)

f(x) = x² + x + 6

Now we can rewrite this in vertex form:

f(x) = (x + 1/2)² + 23/4

So the vertex is (-1/2, 23/4), which is a minimum point on the graph.

Thus,

We can sketch the graph of f(x) = (x + 3)(x - 2) as an upward-opening parabola that crosses the x-axis at -3 and 2 and has a minimum point at (-1/2, 23/4).

It takes 13 hours and 15 minutes to paint longer walls of the house

Step-by-step explanation:

Given:

Rectangular house. Painting of the longer walls takes 8 hours longer than painting shorter walls.Total time to paint is 18.5 hours.

Let the length of shorter sides be x and longer sides be y.

Then we have the system:

y = x + 8x + y = 18.5

Solve it by substitution:

x + x + 8 = 18.52x + 8 = 18.52x = 10.5x = 10.5/2x = 5.25

Find the value of y:

y = 5.25 + 8 = 13.25 hours or 13 hours and 15 minutes

Shorter one be x

longer one=x+8

Total time=18.5h

So

x+x+8=18.52x+8=18.52x=18.5-82x=10.5x=10.5/2x=5.25hours

Time required for longer side
