Answer:

Trinomial can not be factored

Step-by-step explanation Equation at the end of step 2 : 4x 2 - 2x - 1 = 0 Step 3 : Parabola, Finding the Vertex : 3.1 Find the Vertex of y = 4x 2-2x-1 Parabolas have a highest or a lowest point called the Vertex . Our parabola opens up and accordingly has a lowest point (AKA absolute minimum)

What is the equation of the line that is parallel to the given
frez [133]

Answer:

<h2>y = 1/5x + 4</h2>

Step-by-step explanation:

We need to find the equation of the line parallel to the given line. To do this, we first need to understand what parallel lines are.

Rule 1: Parallel lines are two lines that never cross.

Let's solve!

To solve, we need to know what the slope of the line should be as we are already given the point it should pass through. to do this, we need to use a rule.

Rule 2: The slopes of parallel lines are always the same.

Slope = change y / change x

-4 - -3 (-4 + 3) = -1

-5 - 0 = -5

Slope = 1/5

Now, we can construct our equation

y = mx + b

y = 1/5x + 4

Since none of the answers are this, I assume you meant perpendicular instead. In that case, the answer would be, since the slope would be an opposite inverse of the original line, -5x + 4.

I'm always happy to help :)

The length of side X is 36.25 cm to the nearest hundredth of a centimeter what is the length of y
goldenfox [79]

Answer:

<h3>The length of y is 62.82 cm.</h3>

Step-by-step explanation:

We are given a right triangle with an angle 30°.

Opposite side of angle 30° is x and adjacent side is y.

Also, given length of side x=36.25 cm.

In order to find the value of y, we need to apply tangent trigonometrical ratio.

We know,

tan \theta =\frac{Opposite \ Side}{Adjacent \ Side}

Therefore,

tan \theta =\frac{x}{y}

Plugging values of \theta =30^o and x=36.25, we get

tan 30^o=\frac{36.25}{y}

Plugging value of tan 30^o=0.577 in above equation, we get

0.577=\frac{36.25}{y}

On multiplying both sides by y, we get

0.577\times y=\frac{36.25}{y}\times y

0.577y=36.25

Dividing both sides by 0.577, we get

\frac{0.577y}{0.577} =\frac{36.25}{0.577}

y=62.82

<h3>Therefore, the length of y is 62.82 cm.</h3>
