Using the quadratic formula to solve 2x2 = 4x – 7, what are the values of x?

Answers

You have to make sure you follow this step by step

Step-by-step explanation:

Step 1:  Subtract 4x from both sides

[tex]2x^2 - 4x = 4x - 4x - 7[/tex]

[tex]2x^2 - 4x = -7[/tex]

Step 2:  Add 7 to both sides

[tex]2x^2 - 4x + 7 = -7 + 7[/tex]

[tex]2x^2 - 4x + 7 = 0[/tex]

Step 3:  Use the Quadratic Formula

[tex]x = \frac{ -b \pm \sqrt{b^2 -4ac} }{2a}[/tex]

[tex]x = \frac{ -(-4) \pm \sqrt{(-4)^2 - 4(2)(7)} }{ 2(2 )}[/tex]

[tex]x = \frac{ 4 \pm \sqrt{-40} }{4}[/tex]

[tex]x = \frac{4 \pm2i \sqrt{10} }{4}[/tex]

[tex]x = \frac{2 \pm i\sqrt{10}}{2}[/tex]

Answer:  [tex]x = \frac{2 \pm i\sqrt{10}}{2}[/tex]

The statements that are true about the considered figure (given below) are given by: Option C: It is a triangular prism, Option F: It has 5 faces

What is a triangular pyramid?

Take a traingle. This is a base. Now take 3 triangles such that each of them are connected to one-one side of the first traingle and when they're taken together, they form a closed object, called as a triangular pyramid

What is a rectangular pyramid?

Take a rectangle. This is the base. Now take 4 triangles such that each of them are connected to one-one side of the base rectangle and when they're taken together, they form a closed object. That shape is called rectangular pyramid.

What is a triangular prism?

Connect three rectangles edge to edge. Now close their triangular mouths from both ends. That shape is called a triangular prism.

What are vertices, faces and edges?

Faces are planar mathematical objects. Like a triangle, a rectangle etc. Edges are those line segments, which are on the edge of the faces (of some object considered).

Vertices are points of intersections of different edges.

The missing figure is attached below.

It consists of 3 rectangles joined edge to edge, and have two triangular ends in the shape they form, thus, making a triangular prism.

There are 6 vertices of a triangular prism, here for this figure, they're named as A,B,C,D,E,FThere are 9 edges of that object AB, AC, AE, BF, BC, CD, ED, FD, EFThere are 5 faces (2 triangles and 3 rectangles). ABC, DEF, ACDE, BFEA, BCFD

Thus, the statements that are true about the considered figure (given below) are given by: Option C: It is a triangular prism, Option F: It has 5 faces

Charles plots the point with the polar coordinates (−5,−3π/4). How does he plot this point?

Charles first determines which line the angle of rotation places the point on. This line tells Charles that the point must lie in _____ a if r is positive or ____ if r is negative.

The radius of 5 tells Charles that the point lies on the fifth circle of the polar plane. The value of r is negative. Therefore, the point will lie _____ the angle of rotation.

Answers

Answer:

This line tells Charles that the point must lie in Quadrant 3 if r is positive or Quadrant 1 if r is negative.

The value of r is negative. Therefore, the point will lie in the opposite quadrant as the angle of rotation.

Step-by-step explanation:

With polar coordinates the first value represents the distance from the origin and the second value represents the rotation from 0. In this case the distance from the origin value is negative, which means it will be in the opposite quadrant to the angle of rotation.

(-5, −3π/4) results in the same point as (5, π/4)

A rotation of −3π/4 results in the same rotation as 5π/4

The rotation results in Quadrant 3 but because the distance value is negative the final resulting point is in Quadrant 1.

A whole number is 6 more than 2 times another number. The sum of the two numbers is less than 50. This can be written in an inequality as x + 2x + 6 < 50, where x represents the smaller number. From the set {13, 14, 15, 16, 17}, the values of x for which the inequality holds true are .

Answers

Answer:

First, you have to simplify the inequality and solve for x.

x + 2x + 6 < 50

3x + 6 < 50

3x < 44

x < 14 2/3

 

So, you now have another set of numbers, {13, 14, 15, 16, 17}, and you know x must be smaller than 14 2/3. The only two numbers in that set that works are 13 and 14, making A: {13, 14} the correct answer.

Write the first six terms of the sequence.

ao = -5, An = 3an-1 + 12

Answers

Answer:

The first six terms of the sequence are -3, 3, 21, 74, 234 and 714

Step-by-step explanation:

Given the initial value a0 = -5 and the general form of the sequence given as An = 3an-1 + 12

To get the first six terms of the sequence, we will substitute for n=1 up to n= 6 in the general equation.

when n=1

A1 = 3a(1-1)+12

A1 = 3a0+12

A1 = 3(-5)+12

A1 = -15+12

A1 = -3

when n=2;

[tex]A2 = 3a(2-1)+12\\A2 = 3a1+12\\A2 = 3(-3)+12\\A2= -9+12\\A2= 3\\\\A3= 3a(3-1)+12\\A3= 3a2+12\\A3 = 3(3)+12\\A3= 9+12\\A3= 21\\\\A4= 3a(4-1)+12\\A4 = 3a3+12\\A4= 3(21)+12\\A4= 63+12\\A4 = 74\\\\A5= 3a(5-1)+12\\A5 = 3a4+12\\A5= 3(74)+12\\A5= 222+12\\A5 = 234\\\\\\A6= 3a(6-1)+12\\A6 = 3a5+12\\A6= 3(234)+12\\A6= 702+12\\A6 = 714\\[/tex]

Which expression is represented by the
phrase "the square of y decreased by
quotient of 36 and 6"?

Answers

Answer: y^2 - 6

Step-by-step explanation:

We are given the statement which is:

The square of y decreased by the quotient of 36 and 6

We need to get the mathematical expression for the question.

Power 2 is used for square and

The sign "/" is used for quotient or division.

The sign "-" is used to subtract or decrease.

Using the sign above,

Square of y = y^2

Quotient of 36 and 6 = 36/6

The square of y decreased by the quotient of 36 and 6 = y^2 - 36/6

= y^2 - 6

Therefore, the required expression is:

y^2 - 6

The phrase is y^2 - 6.

The phrase "the square of y decreased by the quotient of 36 and 6" translates to the mathematical expression y2 - (36 / 6). This expression involves two operations:

Finding the square of y, which is y multiplied by itself (y2).Calculating the quotient of 36 and 6, which is 36 divided by 6, resulting in 6.

Then, you decrease the square of y by this quotient, which gives you the final expression y2 - 6.

x = 10

Step-by-step explanation:

This is because the formula of the area of a triangle is b x h divided by 2.

Since 8 is the base, you have to find what to multiply it by to get 80 (since 80 divided by 2 is the answer, 40).

80 divided by 8 is 10, therefore the base, or x, is 10.

You can put it in the formula to double check and it will equal 40.

What is Percentage?

percentage, a relative value indicating hundredth parts of any quantity.

We can use the formula for compound interest to solve this problem:

[tex]A = P(1 + r/n)^(^n^t^)[/tex]

where A is the total amount,

P is the principal

r is the annual interest rate,

n is the number of times the interest is compounded per year, and

t is the number of years.

P = $50,000, r = 0.06, n = 12 and t = 10.

Substituting these values into the formula, we get:

A = 50000(1 + 0.06/12)¹²⁰

A = 50000(1.005)¹²⁰

A=$90970

Explain when the median of a data set is a better
measure of center than the mean.

Answers

Answer:

SAMPLE ANSWER

Step-by-step explanation:

When there is an outlier in the data set, the dot plot or histogram will be skewed. In a skewed representation, the mean is pulled up or down toward the tail of the data. Therefore, skewed data affects the mean more than the median.

The median is a better measure of center than the mean in situations where the data is skewed or contains extreme outliers.

What is a median?

It is the middle value of the given set of numbers after arranging the given set of numbers in order.

We have,

The median and mean are both measures of central tendency used to describe the center of a data set.

The mean is the sum of all the values in a data set divided by the total number of values, while the median is the middle value when the data set is ordered from least to greatest.

The median is a better measure of center than the mean in situations where the data is skewed or contains extreme outliers.

For example, in a data set where one or a few very large or very small values are present, the mean will be influenced by these values, and will not be representative of the central tendency of the data set as a whole.

In such cases, the median is a more appropriate measure of the center as it is not influenced by outliers and better represents the "typical" value in the data set.

Thus,

When a data set is skewed or contains outliers, the median is a better measure of the center than the mean.
