2. yes this graph represents a polynomial, this line is of the form y=mx+b; there are no turning points as it is a polynomial of degree 1.

Step-by-step explanation:

For problem 1:

as can be seen in the given graph, the graph of 1/x is ended at the value of x=1 and for all the values of x>1.

so the condition x<1 and x[tex]\neq[/tex]0 applies here

then for graph [tex]\sqrt[3]{x}[/tex], the graph starts from (1,1) and there is no extension of it beyond the value of x=1.

so the condition x[tex]\geq[/tex]1 applies here.

For Problem 2:

the given graph is a linear line which is represent by polynomial y=mx+b

and the polynomial y=mx+b is a polynomial of degree 1.

As the given graph is a graph of straight line represented by y=mx+b there are no turning points.

Answer:

B.) [tex]1\frac{7}{12}[/tex]

Step-by-step explanation:

[tex]2\frac{1}{4} -\frac{2}{3}

Then multiply 4 by 2, then add 1.

frac{9}{4} - \frac{2}{3} \\[/tex]

Then find the Least Common Denominator(LCD); simply just multiply 4 by 3 to get 12; then multiply using the opposite number.

[tex]\frac{3}{3} *\frac{9}{4} - \frac{4}{4} * \frac{2}{3}[/tex]

to get: [tex]\frac{27}{12} - \frac{8}{12}[/tex].

now the denominators is the same on both sides, just subtract the numerator.

27 - 8 = 19

Now simply: [tex]\frac{19}{12} = 1\frac{7}{12}[/tex].

Your final answer is 1\frac{7}{12}[/tex].

Explanation

If you doing sine, cosine, and tangent, just remember SOHCAHTOA.

Answer: z = -3 , y = 2 , x = 2

The solution to the system of equations is: x - y + 9z = -27 , 2x - 4y - z = -1 , 3x + 6y - 3z = 27 is

x = 2

y = 2

z = -3

Given the system of equations:

1. x - y + 9z = -27

2. 2x - 4y - z = -1

3. 3x + 6y - 3z = 27

We'll use the method of elimination to solve this system.

Step 1: Eliminate y from equations (1) and (2):

Adding equations (1) and (2):

(x - y + 9z) + (2x - 4y - z) = -27 + (-1)

x + 2x - y - 4y + 9z - z = -27 - 1

3x - 5y + 8z = -28

Step 2: Eliminate y from equations (2) and (3):

Multiplying equation (2) by (3) and equation (3) by (2):

6x - 12y - 3z = -3  (from equation 2)

6x + 12y - 6z = 54 (from equation 3, after multiplying by 2)

Adding these two equations:

(6x - 12y - 3z) + (6x + 12y - 6z) = -3 + 54

6x + 6x - 12y + 12y - 3z - 6z = 51

12x - 9z = 51

Now, we have two equations:

1. 3x - 5y + 8z = -28

2. 12x - 9z = 51

From equation (2), let's solve for (x):

12x - 9z = 51

12x = 51 + 9z

x = (51 + 9z) ÷ 12

Now, we'll substitute this expression for (x) into equation (1) to solve for (z):

3x - 5y + 8z = -28

[tex]\[ 3\left(\frac{51 + 9z}{12}\right) - 5y + 8z = -28 \][/tex]

[tex]\[ \frac{153 + 27z}{12} - 5y + 8z = -28 \][/tex]

Next, we'll isolate (z):

153 + 27z - 60y + 96z = -336

249z - 60y = -489

Now, let's solve for (z):

249z = -489 + 60y

z = (-489 + 60y) ÷ 249

Now, we'll substitute the expression for (z) back into equation (2) to solve for (y):

[tex]\[ 12x - 9\left(\frac{-489 + 60y}{249}\right) = 51 \][/tex]

[tex]\[ 12x - \frac{-489 + 60y}{27} = 51 \][/tex]

[tex]\[ 12x = 51 + \frac{-489 + 60y}{27} \][/tex]

[tex]\[ x = \frac{51 + \frac{-489 + 60y}{27}}{12} \][/tex]

[tex]\[ x = \frac{51\times27 + -489 + 60y}{12\times27} \][/tex]

[tex]\[ x = \frac{1377 - 489 + 60y}{324} \][/tex]

[tex]\[ x = \frac{888 + 60y}{324} \][/tex]

[tex]\[ x = \frac{148 + 10y}{54} \][/tex]

Now, we'll substitute the expressions for (x) and (z) into equation (1) to solve for (y):

x - y + 9z = -27

[tex]\[ \frac{148 + 10y}{54} - y + 9\left(\frac{-489 + 60y}{249}\right) = -27 \][/tex]

The least common multiple of (54) and (249) is (54 × 249).

⇒ (148 + 10y) × 249 - 54 × 249 × y + 9 × 54 × (-489 + 60y)  = -27 × 54 × 249

⇒ 36752 + 2490y - 133146y - 233640 + 29160y = -1458 × 249

⇒  2490y - 133146y + 29160y + 36752 - 233640 = -1458 × 249

⇒ -106496y - 197888 = -362682

⇒ -106496y = -164794

⇒ y = (-164794) ÷ (-106496)

y ≈ 1.547

y ≈ 2

Now that we have found (y = 2), we can substitute this value back into the expressions for (x) and (z) to find their values.

For (x):

[tex]\[ x = \frac{148 + 10(2)}{54} = \frac{168}{54} = 2 \][/tex]

For (z):

[tex]\[ z = \frac{-489 + 60(2)}{249} = \frac{-369}{249} = -\frac{3}{1} = -3 \][/tex]

So, the solution to the system of equations is:

x = 2

y = 2

z = -3

Answer:

9. ∠A ≅ ∠R

10. SI ≅ GH

11. MN ≅ RN

12. FE ≅ TU

Step-by-step explanation:

Look at the reason identifier: A means "angle"; S means "side". The order is important. AAS means two adjacent angles with only one of them next to the corresponding sides. SAS means the angle is between two corresponding sides.

9. Sides CS and TS correspond and are congruent. The vertical angles at S are congruent, so the AAS identifier means you're looking for angles A and R to be congruent. (Using angles C and T would invoke the ASA identifier.)

__

10. Sides HI are congruent; the angles at H and I are congruent. The SAS identifier means you're looking for the sides on the other side of those angles to be congruent: sides SI and GH.

__

11. SSS means you're claiming all three sides are congruent to their corresponding sides. The common side is congruent to itself; the marked sides are congruent. So, you need the unmarked sides to be congruent to each other.

__

12. HL means you're claiming the hypotenuse and one leg of the right triangle are congruent. One leg is already marked, so you need the hypotenuses to be congruent.

Answer:

The measures of angles of this Δ are 23° , 67° , 90°

Step-by-step explanation:

* Lets talk about some facts in the circle

- An inscribed angle is an angle made from points sitting on the

 circle's circumference

- A central angle is the angle formed when the vertex is at the center

 of the circle

- The measure of an arc of a circle is equal to the measure of the

 central angle that intercepts the arc.

- The measure of an inscribed angle is equal to 1/2 the measure of

 its intercepted arc

- An angle inscribed across a circle's diameter is always a right angle

- The triangle is inscribed in a circle if their vertices lie on the

  circumference of the circle, and their angles will be inscribed

  angles in the circle

* Now lets solve the problem

- Δ ABC is inscribed in a circle

∵ its side AB is a diameter of the circle

∵ Its vertex C is on the circle

∴ ∠C is inscribed and across the circle's diameter

∴ ∠C is a right angle

∴ m∠C = 90°

∵ The measure of arc BC = 134°

∵ ∠A is inscribed angle subtended by arc BC

∵ The measure of an inscribed angle is equal to 1/2 the measure

   of its intercepted arc

∴ m∠A = 1/2 × 134° = 67°

∵ The sum of the measures of the interior angles of a triangle is 180°

∵ m∠A = 67°

∵ m∠C = 67°

∵ m∠A + m∠B + m∠C = 180°

∴ 67° + m∠B + 90° = 180°

∴ 157° + m∠B = 180° ⇒ subtract 157 from both sides

∴ m∠B = 23°

* The measures of angles of this Δ are 23° , 67° , 90°

For this case we must simplify the following expression:

[tex]\sqrt [3] {64 * a ^ 6 * b ^ 7 * c ^ 9}[/tex]

We rewrite:

[tex]64 = 4 ^ 3\\a ^ 6 = (a ^ 2) ^ 3\\b ^ 6 * b = ((b ^ 2) ^ 3 * b)\\c ^ 9 = (c ^ 3) ^ 3[/tex]

So:

[tex]\sqrt [3] {4 ^ 3 * (a ^ 2) ^ 3 * (b ^ 2) ^ 3 * b * (c ^ 3) ^ 3} =\\\sqrt [3] {4 * a ^ 2 * b ^ 2 * c ^ 3) ^ 3 * b} =[/tex]

By definition of properties of powers and roots we have:

[tex]\sqrt [n] {a ^ m} = a ^ {\frac {m} {n}}[/tex]

So:

[tex]4a ^ 2b ^ 2 c ^ 3 \sqrt [3] {b}[/tex]

Answer:

Option B

Answer:

x1= 14/4 and X2 = -2

Step-by-step explanation:

To find the values of "X" for which when the function is evaluated gives 19 we need to equal the function to 19, as follows:

2x^2+3x+5 = 19

2x^2+3x+5-19=0

2x^2+3x-14=0

Then, solving for "x" we need to use the quadratic formula (Attached), where a, b, and c, are the following:

a: 2 b: 3 c: 14

Using the quadratic formula, we get:

x1= 14/4 and X2 = -2

Step-by-step explanation:

We have been given an image of intersecting lines. We are asked to find the pair of angles that must be supplementary.

We know that two angles are supplementary when they add up-to 180 degrees.

Upon looking at our given image, we can see that the measure of angle 2 and measure of angle 5 is 90 degrees. So these angles will add up-to 180 degrees, therefore, option B is the correct choice.

ANSWER

[tex]( \sin(x) + 2)( \sin(x) - 1)[/tex]

EXPLANATION

The given trigonometric function is:

[tex] \sin^{2} x + \sin(x) - 2[/tex]

This is a quadratic trinomial in sinx

We split the middle term to obtain:

[tex]\sin^{2} x + 2 \sin(x) - \sin(x) - 2[/tex]

[tex] \sin \:x ( \sin(x) + 2 ) - 1( \sin(x) + 2)[/tex]

The factors are:

[tex]( \sin(x) + 2)( \sin(x) - 1)[/tex]

Answer:

B

Step-by-step explanation:

Using the law of sines, we can make a proportion.

But first, we'll need to solve for the unknown angle.

We add up the two known angles and subtract that by 180.

90 + 41 = 131

180 - 131 = 49

So the unknown angles is 49.

Then, we can use the law of sines.

Make the equation.

sin(90)/55 = sin(49)/x

Simplify this using a calculator and you get around 41.51 or option B.

The correct option is B. [tex]41.51[/tex] The value of [tex]\( x \)[/tex] to the nearest hundredth

To find the value of [tex]\( x \)[/tex] to the nearest hundredth, we need to use the trigonometric functions for the right triangle given.

We are given:

The hypotenuse [tex](\( 55 \))[/tex]

An angle [tex](\( 41^\circ \))[/tex]

We need to find the adjacent side[tex](\( x \))[/tex]

We can use the cosine function, which is defined as:

[tex]\[\cos(\theta) = \frac{\text{adjacent}}{\text{hypotenuse}}\][/tex]

Substituting the given values:

[tex]\[\cos(41^\circ) = \frac{x}{55}\][/tex]

Solving for \( x \)

[tex]\[x = 55 \times \cos(41^\circ)\][/tex]

Using a calculator to find \(\cos(41^\circ)\)

[tex]\[\cos(41^\circ) = 0.7547\][/tex]

Now, multiplying:

[tex]\[x = 55 \times 0.7547 = 41.5085\][/tex]

To the nearest hundredth, \( x \) is:

Answer:

Vertical asymptotes: x=-9 and x=3

Slant asymptote: y=5x-1

Step-by-step explanation:

Given

f(x)=(5x^3+29x^2-140x+21)/(x^2+6x-27)

For vertical asymptote, the denominator is put equal to zero,so

x^2+6x-27=0

Factorizing

x^2+9x-3x-27=0

x(x+9)-3(x+9)=0

(x+9)(x-3)=0

So,

x=-9 ;x=3

As the degree of the numerator is greater than the denominator the function will not have horizontal asymptote but it will have a slant asymptote which will be calculated by long division.

After dividing 5x^3+29x^2-140x+21  by x^2+6x-27  we get

Quotient: 5x-1

Remainder: x-6

We only need the quotient for the slant asymptote,
