Answer:

x = -5, \frac{1}{2}

Step-by-step explanation:

The given equation is 2x² + 9x - 5 = 0

We have to find the values of x.

We know that if in a quadratic equation ax²+ bx + c = 0, b²- 4ac > 0 then there will be two real roots of the equation.

In the given equation b²- 4ac = (9)²-4(2)(-5) = 81 + 40

                                                = 212 > 0

So there will be two real roots.

Now we will factorize the given equation.

2x² + 9x - 5 = 0

2x² + 10x - x - 5 = 0

2x(x + 5) - 1(x + 5) = 0

(2x - 1)(x + 5) = 0

So two roots will be 2x - 1 = 0

x = \frac{1}{2}

and x + 5 = 0

x = -5

Therefore, x = -5, \frac{1}{2} are the solutions.

Select the graph of y=cot x.
Kisachek [45]

Because of the vertical asymptote and the change in concavity, we conclude that the correct option is B.

<h3>Which is the graph of cotangent of x?</h3>

Remember that cot(x) = 1/tan(x).

Then we can rewrite:

cot(x) = cos(x)/sin(x).

We know that for x = 0, we have:

cot(0) = cos(0)/sin(0) = 1/0

Then we have a vertical asymptote that tends to ± infinity.

The only graph that meets this condition is the second and the third one, and by the curvature (we need to have a change of concavity/convexity) in the tangent function.

From that, we conclude that the correct option is B.

An angle measures 32degrees what is the measure of its complement
Alex787 [66]

The measure of 32° complement is 58°.

<h3>What is an angle?</h3>

An angle is a geometry in plane geometry that is created by 2 rays or lines that have an identical terminus.

The identical endpoint of the two rays—known as the vertex—is referenced as an angle's sides.

The angle is the measurement of the angular distance for example for linear motion we have a meter inch but for angular rotation, we don't have the measurement so the angle is useful to measure the angular rotation.

Given,

The measure of an angle = 32°

Complimentary angles are those angles whose sum is 90°

So,

Compliment + 32° = 90°

Compliment = 90 - 32 = 58°.

Hence "The measure of 32° complement is 58°".

For more about the angle,
