The equation of the vertical parabola in vertex form is written as

Where (h, k) are the coordinates of the vertex and p is the focal distance.

The directrix of a parabola is a line which every point of the parabola is equally distant to this line and the focus of the parabola. The vertex is located between the focus and the directrix, therefore, the distance between the y-coordinate of the vertex and the directrix represents the focal distance.

Using this value for p and (3, 1) as the vertex, we have our equation

Given: The coordinates of a trapezoid as below

To Determine: The final step on the trapezoid after it is reflected over the x-axis and then reflected over the axis

Solution

Please note that a reflection over the x-axis and reflection over the y-axis is different from the last step, which is a reflection over the y-axis

The reflection over the y-axis could either be a rotation of 90^0 clockwise or anticlockwise.

So get the trapezid onto itself after a reflection over the y-axis from a reflection over teh x-axis requires two steps

We have step 1: Reflection over the x-axis, then

Step 2: Reflection over the y-axis

Hence, the final step is reflection over the y-axis

What to find?

The power function that the given graph resembles.

Given:

f(x)=(x − 3)³

First, we need to note that;

If f(x) is shifted left q - units, then the new formula of the function becomes f(x+q).

Let q=3

ANSWER

y=x³

The number that satisfies the equation is

Doing the square root on both sides

On complex number we use the definition:

Therefore, the number that satisfies the equation is

That means that a solution is a complex number.

Complex numbers have two parts, the complex part and the real part:

Look that a and b are real coefficients, but z is a complex number because we have b multiplying i, the complex unit.

But why complex numbers are so important?

• Complex numbers can be used to solve polynomial equations, that we couldn't solve before

• Complex numbers can connect exponential function with trigonometric functions

Complex numbers are a powerful set that we can use to solve many complex problems in physics and mathematical, it may seem hard but they actually make things easier, sometimes working with complex numbers is way easier than working with real numbers.

We are to find the recursive formular

A recursive geometric formular has a pattern:

An = An - 1 * r

Where r is the common ratio. But before we write the formular, we need to look for the value of r.

This r value has to be the same between each consecutive number in the series.

Sinces it's geometric, r is multiplied in. To get from 1/2 to 3/2 we find the r value in this way:

x/2 = 3/4 where x/2 is the same as 1/2 x.

Cross multiply to get 4x = 6 and x = 3/2.

That means that if r is 3/2, then we can multiply every term in that sequence by 3/2 to get the next term in line.

3/4 times 32 is 9/8. So, r = 3/2 and the formulat is:

An = An - 1 * 3/2

Therefore, the crrect optio is B.

For the given function,

             Vertical Asymptote:-  x =-3

             Horizontal asymptote:- y =20

             Oblique asymptote :- No oblique asymptote

Asymptote:

                     A vertical asymptote is found by letting the denominator equal zero. A horizontal asymptote is found by comparing the leading term in the numerator to the leading term in the denominator. The degree of the numerator is greater than the degree of the denominator, so there is no horizontal asymptote.

                                                            Oblique asymptotes occur when the degree of the denominator of a rational function is one less than the degree of the numerator

given,

            R(x) = [tex]\frac{20x}{x+3}[/tex]

Vertical Asymptote:-

                                  Equate denominator to zero

                                    x +3 = 0

                                        x = -3

Horizontal asymptote:-

                                   Here degree on x in numerator and denominator is same,

              so horizontal asymptote will be,  

                                y= 20/1

                                y = 20

Oblique asymptote:-

                                 There won't be any slant asymptote, because degree in numerator is equal to the degree in denominator.

Here, we want to use the given information to calculate the lateral and the total surface area

To find the lateral area, we have to calculate the perimeter of the base and multiply this by the height of the triangular prism

Now, we will make the shape lie on its side

This mean the triangles will represent the base

Mathematically, the perimeter of a triangle is the sum of its side

We need the last side of the triangle

We can get this by the use of Pythagoras' theorem

As we can see, the side measure 5 is the hypotenuse as it faces the right angle

The square of the hypotenuse equals the sum of the squares of the two other sides

3,4 and 5 are a Pythagorean triple

This means that, the measure 3 is the last side of the triangle

So the perimeter is;

The height is the measure 8 inches

Thus, the lateral area is;

Now, we want the total surface area, but firstly, we need the area of the base

The area of the base is the area of the triangle

two times this is 12 in^2

The total suface area is thus;

The parent function is:

y = x²

This is a quadratic function

The child functions are:

y = x - 4² whcih can be written as

y = x - 16

The second child function is

y = x + 3

The two child functions are linear functions while the parent function is a quadratic function.

The parent and child functions also differ in their ranges and domains

Domain = ( -∞ , ∞ )

Range = [0 , ∞ )

Domain = ( -∞ , ∞ )

Range = (-∞ , ∞ )

The difference between y = x - 4² and y = x + 3 is their intercepts on the y axis .

For y = x - 4², the y - intercept is -16

For y = x + 3, the y - intercept 3

This change is due to transformation (basically translation) on the x and y axes

Part 1.

We have a confidence interval (C.I.) of 80%.

We need to find the z-score for this C.I., so, let's see a diagram:

We have a two-sided confidence interval. So, we need to find the z-score for a cumulative probability of 80+10=90%=0.9.

By using a standard normal table, we can see that z-score for 0.9 is:

By using an online calculator, we find the exact z-score is 1.282.

The confidence interval is given by the formula:

Where x is the mean of the sample, Zc is the z-score for the given confidence level, s is the standard deviation and n is the number of elements in the sample n=50.

By replacing the known values, we obtain:

So, the lower and upper limits are:

The margin of error is equal to half the width of the entire confidence interval, and it is also the value we add and subtract to the mean to find the confidence interval, so the margin of error is 2.585.
