Which of the following are In The correct order from least to greatest?

Answer:

B. x= -1

Step-by-step explanation:

axis of symmetry is: [tex]x=\frac{-b}{2a}[/tex]

[tex]x=\frac{-4}{2(2)} \\x=\frac{-4}{4}\\x=-1[/tex]

The axis of symmetry for the given parabola equation y = 2x²+ 4x - 1 is x = -1.

The axis of symmetry of a parabola in the form y = ax² + bx + c can be found using the formula x = -b/(2a). For the given equation y = 2x² + 4x - 1, we can identify a as 2 and b as 4. Substituting these values into the formula for the axis of symmetry gives us x = -4/(2²) = -1.

The answer is 3. You would just match up the sides and combine the common things. 3z times z is 3z^2 because it would be the same number twice, not times two. Then 9 times 8 is 72. Z times 8 is 8z because it would be 8 times whatever number the variable was. Then lastly it’s 9 times 3 z. You’ll multiply the 9 times 3 to get 27. Then it would be 27z. 27z and 3z^2 cannot be added together because they are preforming different things. One is multiplying by the variable another is multiplying by 3 and the the variable to the 2nd power.

Answer:

m<PQR = 80°

Step-by-step explanation:

Points to remember

Sum angles in a linear pair is 180

To find the value of x

It is given that, angle PQR and angle RQS are linear pairs, and

m< PQR =5x+5 and m<RQS =11x-65

m<PQR + m<RQS = 180

5x + 5 + 11x - 65 = 180

16x -60 = 180

16x = 180 + 60

16x = 240

x = 15

To find the value of angle PQR

m<PQR = 5x + 5

 = 5*15 + 5

 = 75 + 5 = 80

Therefore m<PQR = 80°

Answer:

2(x - 10)(x + 10)

Step-by-step explanation:

Given

2x² - 200 ← factor out 2 from each term

= 2(x² - 100) ← x² - 100 is a difference of squares and factors as

x² - 100 = x² - 10² = (x - 10)(x + 10), hence

2x² - 200 = 2(x - 10)(x + 10)

Answer:

Step-by-step explanation:

If your equation is [tex]2x^2-200[/tex] and you're to factor it, the first thing you do is set the expression equal to 0 so you can solve for x.

[tex]2x^2-200=0[/tex]

There's a couple of different ways in which to approach this.  You can factor out a 2:

[tex]2(x^2-100)=0[/tex]

and solve it from there.  The Zero Product Property says that if the equation is equal to 0, then either 2 has to equal 0 or [tex]x^2-100[/tex] has to equal 0.  We know that 2 does not equal 0, so [tex]x^2-100=0[/tex]

Add 100 to both sides in the equation:

[tex]x^2=100[/tex]

and then take the square root of both sides.  Because this is a second degree polynomial, we expect to have 2 solutions, and we do.  Don't forget that when you take the square root of a number you have to alow for both the positive and the negative of the result.  Our factored form of the given equation then is that x = 10 and x = -10.

Answer:

the graph of the parabola opens upwards.

Step-by-step explanation:

For any quadratic equation of the form

[tex]ax ^ 2 + bx + c[/tex] is true that:

if the main coefficient "a" is negative then the graph of the parabola opens downwards.

If the main coefficient "a" is positive, the parabola opens upwards

In this case the parabola is [tex]y=x^2-6x[/tex]

Note that [tex]a=1[/tex] and [tex]a>0[/tex] therefore the graph of the parabola opens upwards.

If your "and" means multiplication than:

[tex]-2\times\frac{1}{3}-(-5) \\

\frac{-2}{3}+5 \\

\frac{-2+15}{3} \\

\boxed{\frac{13}{3}\approx4.33\dots}

[/tex]

If it is a logical and than we are unable to solve the problem since you didn't provide any variables that would have a meaningful values.

Hope this helps.

Answer:

Option a)72.8 sq. cm.

Step-by-step explanation:

step 1

Find the measure of the third internal angle of the triangle

Remember that

the sum of the internal angles of a triangle must be equal to 180 degrees

so

95°+35°+A=180°

A=180°-95°-35°

A=50°

step 2

Applying the law of sines

Find the length side opposite to the angle of 35 degrees

14/sin(50°)=b/sin(35°)

b=[14/sin(50)]*sin(35)

b=10.48 cm

step 3

Applying the law of sines find the area of the triangle

A=(1/2)(14)(10.48)sin(95°)=73.10 cm²

therefore

The approximate area of the triangle below is 72.8 sq. cm

Answer:

72.8 sq. cm

Step-by-step explanation:

Given:

two angles and a side of a triangle that are 95°, 35° and 14 cm receptively

Area of triangle=?

Finding 3rd angle

=180-(95+35)

= 180-130

=50

Area of triangle can be calculated by using ASA i.e.

Area= a^2sinBsinC/2sinA

Putting values of a=14, B=95, C=35 and A=50, we get

Area= 14^2(sin95)(sin35)/2(sin50)

       =98(0.74591)

        =73.099

Closest option is a)72.8 sq. cm!

You can always compute the distance between two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] using the pythagorean theorem:

[tex]d = \sqrt{(x_1-x_2)^2+(y_1-y_2)^2}[/tex]

In your case, we have

[tex]d = \sqrt{(0-a)^2+(a-0)^2} = \sqrt{2a^2}=a\sqrt{2}[/tex]

Answer:

[tex]\sqrt{2}a[/tex]

Step-by-step explanation:

We are asked to find the distance between point (0,a) and point (a,0) on a coordinate grid.

We will use distance formula to solve our given problem.

The distance between two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is given by formula:

[tex]D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex], where D represents distance between two points.

Let point [tex](0,a)=(x_1,y_1)[/tex] and point [tex](a,0)=(x_2,y_2)[/tex].

Substitute the values in distance formula:

[tex]D=\sqrt{(0-a)^2+(a-0)^2}[/tex]

[tex]D=\sqrt{(-a)^2+(a)^2}[/tex]

[tex]D=\sqrt{a^2+a^2}[/tex]

[tex]D=\sqrt{2a^2}[/tex]

Factor out perfect square:

[tex]D=\sqrt{2}a[/tex]

Therefore, the distance between two points would be [tex]\sqrt{2}a[/tex].

Answer: c

Step-by-step explanation:

sampling variability is the difference between the measured value of the random sample and the mean age of the population

Option A demonstrates sampling variability because the mean age changes between two random samples chosen from the same population, illustrating the concept of sampling variability in statistics.

The subject of this question is a concept in statistics known as sampling variability. Sampling variability refers to the idea that the statistics of a random sample of a population (like mean, median, etc.) will vary from one sample to another. In essence, if we were to keep pulling samples from the same population, it's expected that our sample statistics will not always be the same.

In this context, the statement that demonstrates sampling variability is Option A: 'In one random sample chosen from the population, the mean age was 9.4 years. In another random sample, the mean age was 9.8 years.'. This demonstrates sampling variability because the mean age changes (varies) depending on the sample chosen from the population.

answer would be the second one: Rectangle that is not a square

Answer:

B.Rectangle that is not a square.

Step-by-step explanation:

We are given that Cecile drew a 4-sides figure. it means a quadrilateral.It had 2 sides that were 3.4cm long and 2 sides that were 3.3 centimeters long.

We are given that a quadrilateral had atleast 3 right angles.

If a quadrilateral had 3 right angles then the IV angle of quadrialteral is also right angle.

In quadrlateral ABCD

[tex]\angle A=90^{\circ}[/tex]

[tex]\angle B=90^{\circ}[/tex]

[tex]\angle C=90^{\circ}[/tex]

[tex]\angle A+\angle B+\angle C+\angle D==360^{\circ}[/tex]

By angle sum property of quadrilateral

[tex]90+90+90+\angle D=360[/tex]

[tex]270+\angle D=360[/tex]

[tex]\angle D=360-270=90^{\circ}[/tex]

Hence, IV angle of quadrilateral is also right angle.

Given two sides of quadrilateral are equal and other two sides of quadrilateral are equal.Therefore, the given quadrilateral can be rectangle not square because in square four sides are of equal lengths.

Hence, the given quadrilateral can be rectangle but not square.Therefore, option B is correct.

Answer:

The lines are neither parallel nor perpendicular

Step-by-step explanation:

The first step is to re-write the equations in slope-intercept form. The first equation is given as;

y = -4/5x + 3

This equation is already in slope-intercept form. Its slope is -4/5

The second equation is given as;

4x - 5y = -15

We solve for y;

-5y = -4x - 15

y = 4/5x + 3

The slope of the line is thus 4/5

Parallel lines have equal or identical slopes. The slopes of the two lines are not equal implying that the lines are not parallel. Two lines are said to be perpendicular if the product of their slopes is equal to -1.

The product of the slopes of the two lines is;

(-4/5) * (4/5) = -16/25 ≠ -1

The two lines are not perpendicular

By comparing the slopes of the given equations, y = -4/5x + 3 and 4x - 5y = -15, we find that they are negative reciprocals of each other, indicating that the lines are perpendicular.

To determine whether the given pair of equations represent lines that are parallel, perpendicular, or neither, we need to compare their slopes. The slope-intercept form of a line is y = mx + b, where m represents the slope and b represents the y-intercept.

The first equation is already in slope-intercept form: y = -4/5x + 3, so its slope is -4/5.

To put the second equation into slope-intercept form, we solve for y:
4x - 5y = -15
-5y = -4x - 15
y = (4/5)x + 3

The slope of the second line is 4/5.

Since the slopes of the two lines are negative reciprocals of each other, the lines are perpendicular.

To write the equation for g(x) which is a scaled version of f(x)=x^2, we can use the general form of a quadratic function y=a(x-h)^2+k. The value of a determines the scaling factor.

To write the equation for g(x) which is a scaled version of f(x)=x^2, we can use the general form of a quadratic function y=a(x-h)^2+k. The value of a determines the scaling factor. Since g(x) is a scaled version of f(x), a is the scaling factor. Therefore, the equation for g(x) is g(x)=a(x-h)^2+k, where a is the scaling factor, h is the x-coordinate of the vertex of f(x), and k is the y-coordinate of the vertex of f(x).

The scaled version of the function f(x) = x^2 is g(x) = a * x^2, where a is the scale factor determining the graph's stretch or compression.

If the function g is considered a scaled version of f(x) = x^2, it means that g will also be a quadratic function, but with a constant factor that scales or stretches the graph of f. The general form of a scaled quadratic function is g(x) = a * x^2, where a is the scale factor.

This scale factor a could be any real number. It determines whether the graph of g is narrower or wider compared to f. For example, if a is greater than 1, the graph of g will be narrower; if 0 < a < 1, the graph will be wider; and if a is negative, the graph will be reflected over the x-axis.

Answer:9/20

Step-by-step explanation: 45/100=9/20, 45÷5=9, 100÷5=20 both the denominater and the numerator are divisible by 5.

To write a percent as a fraction in lowest terms, first remember that a percent is a ratio that compares a number to 100. 45% can be written as the ratio 45 to 100 or 45/100. Notice however that 45/100 is not in lowest terms so we need to dive both the numerator and denominator by the greatest common factor of 45 and 100 which is 5.

45 ÷ 5 = 9

100 ÷ 5 = 20

Therefore, 45% can be written as the fraction 9/20.

Cancel 3 on both sides

-2y + 2y = 0

Simplify -2y + 2y to 0

0 = 0
