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.

Answer:2 and 5

Step-by-step explanation:

The solution to the system of equations y=4x+6 and y=2x-4 is (-5, -14) by solving the equations simultaneously.

The solution to the system of equations y = 4x + 6 and y = 2x - 4 is found by setting the two equations equal to each other since they both equal y. This gives us 4x + 6 = 2x - 4. By subtracting 2x from both sides, we get 2x + 6 = -4. Subtracting 6 from both sides gives us 2x = -10. Dividing both sides by 2 gives us x = -5. Substitute x = -5 into either original equation to find y. Let's use the first equation: y = 4(-5) + 6, which simplifies to y = -20 + 6, and finally y = -14. Hence, the solution to the system of equations is (-5, -14).

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.

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.

Step-by-step explanation:

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:

6

Step-by-step explanation:

In order to solve this we must use order of operations or PEMDAS.

Parentheses:

First perform operations within parentheses. In this case, do 8-2.

Now we have 8 - 6 / 3.

Exponents:

There are no exponents.

Multiplication or Division:

Divide 6 by 3.

Now we have 8 - 2.

Addition or Subtraction:

Subtract 8-2.

The answer is 6

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.

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:

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

Step-by-step explanation:

This question is based on the Least Common Multiple (LCM) method. We will find the LCM of the numbers 4, 6 and 8.

4 = 2 x 2 = [tex]2^{2}[/tex]

6 = 2 x 3 = 2 x 3

8 = 2 x 2 x 2 = [tex]2^{3}[/tex]

So, LCM is = [tex]2^{3}\times3=24[/tex]

Therefore, at every 24th houses, we will find all three trolls colors.

And 24 is the number of houses we will find all color trolls. Then in a group of 75 houses, it will occur thrice and at every 24th place. Means. 3 houses will have all color trolls.

[tex]\bf \left( \cfrac{6^5}{7^3} \right)^2\implies \left( \cfrac{6^{5\cdot 2}}{7^{3\cdot 2}} \right)\implies \cfrac{6^{10}}{7^6}\implies \cfrac{60466176}{117649}\implies 513\frac{112239}{117649}[/tex]

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.

Answer:

√55

Step-by-step explanation:

Notice that the small triangle in the bottom corner shares an angle with the overall triangle.  Also, they are both right triangles.  Therefore, they are similar triangles.

Notice that the large triangle at the top shares an angle with the overall triangle and is also a right triangle.  Therefore it is also similar to the overall triangle and the smaller triangle.

Writing a proportion between the small and large triangles:

y / 11 = 5 / y

y² = 55
