Answers

Answer 1

Step-by-step explanation:

x² + 6x + 9 = 2

(x + 3)² = 2

x + 3 = ±sqrt(2)

x = -3 ± sqrt(2)

so, B and D are correct.

control :

(-3 + sqrt(2))² + 6(-3 + sqrt(2)) + 9 = 2

9 + 2 - 6sqrt(2) - 18 + 6sqrt(2) + 9 = 2

2 = 2

correct

(-3 - sqrt(2))² + 6(-3 - sqrt(2)) + 9 = 2

9 + 2 + 6sqrt(2) - 18 - 6sqrt(2) + 9 = 2

2 = 2

correct

(3 + sqrt(2))² + 6(3 + sqrt(2)) + 9 = 2

9 + 2 + 6sqrt(2) + 18 + 6sqrt(2) + 9 = 2

38 + 12sqrt(2) = 2

wrong.

(3 - sqrt(2))² + 6(3 - sqrt(2)) + 9 = 2

9 + 2 - 6sqrt(2) + 18 - 6sqrt(2) + 9 = 2

38 - 12sqrt(2) = 2

wrong.

The first three terms of a sequence are given. Round to the nearest thousandth (if necessary). 7,10,13,...

Find the 33rd term.

Answers

The 33rd term of the arithmetic sequence, 7,10,13.... is: 103

Recall:

An arithmetic sequence has a common difference, d, which is the difference between consecutive terms.nth term of an arithmetic sequence is found using: an = a + (n - 1)d, where, a is the first term and  d is the common difference.

The sequence, 7,10,13,... is an arithmetic sequence because:

13 - 10 = 10 - 7 = 3

Therefore, to find the 33rd term, substitute a = 7, n = 33, and d = 3 into an = a + (n - 1)d.

Thus:

[tex]a_{33[/tex] = 7 + (33 - 1)3

[tex]a_{33[/tex] = 7 + (32)3

[tex]a_{33[/tex] = 103.

Answers

Answer: No

Step-by-step explanation: To determine this, all we have to is plug our ordered pair into the equation for x and y.

Remeber that the first number is our x-coordinate and our second

number is our y-coordinate so we plug a 5 in for x and a 6 in for y.

So we have (6) = 2(5) + 7 or 6 = 10 + 7 or 6 = 17.

Mr. discrete told his students if everyone in the class did at least 35 of the 40 homework assignments for second nine weeks he would add 4% to their final test if he determines the score by doubling the number of correct problems out of 50 and then adding the bonus which inequality would determine the fewest problems a student could answer correctly and still have a A?

Answers

you would have to do very good on it so try 4 questions

A student must answer at least 35 of the 40 homework assignments correctly to get an A.

What is inequality?

Inequality is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are not equal.

To determine the fewest number of problems a student could answer correctly and still get an A, we need to set up an inequality that represents the condition for getting an A.

If Mr. Discrete determines the score by doubling the number of correct problems out of 50 and then adding the bonus, then the score for each student can be represented by the equation:

2x + 4% × 50 = 100, where x is the number of correct problems.

If the student needs to get an A, then the score must be at least 90. Therefore, we can set up the inequality:

2x + 4% × 50 ≥ 90

Substituting 4% for 0.04, we get:

2x + 0.0450 ≥ 90

Solving for x, we find:

x ≥ 35

Therefore, to receive an A, a student must complete at least 35 out of the 40 homework assignments.

Step-by-step explanation:

The first thing that can help you here is factoring every term.

Factor.

[tex](p-6)(p+2)[/tex]

[tex]6p+12[/tex]

Factor.

[tex]6(p+2)[/tex]

18p

Factor, keeping in mind the denominator of the other term.

[tex]6(3p)[/tex]

[tex]p^2-9p+18[/tex]

Factor.

[tex](p-6)(p-3)[/tex]

Now you have simplified your original problem:

[tex]\frac{p^2-4p-12}{6p+12} *\frac{18p}{p^2-9p+18}[/tex]

into:

[tex]\frac{(p-6)(p+2)}{6(p+2)} *\frac{6(3p)}{(p-6)(p-3)}[/tex]

Now, after multiplying the numerator and denominator of the fractions:

[tex]\frac{(p-6)(p+2)(6)(3p)}{(6)(p+2)(p-6)(p-3)}[/tex]

Then, you can simplify the fraction by cancelling terms:

[tex]\frac{3p}{p-3}[/tex]

Read the article "Overcoming Difficulties: How Helen Keller Learned to Communicate" and answer the question.Every day, millions of people worldwide use their mouths to speak, their ears to hear, and their eyes to see. However, not all people have those abilities. Some are born without the ability to speak, see, or hear. Others lose one or all of these abilities due to illness or accident. Not being able to communicate can be a major obstacle, but people who overcome these challenges are often determined, resourceful, and dedicated to helping others. Instead, people who have to overcome these challenges are often determined, resourceful, and dedicated to helping others.A Great TeacherOne person who did not allow her disability to limit her was Helen Keller. Keller, who became blind and deaf at the age of one and a half due to illness, learned at a very young age that her life was going to be different. As a child in the late 1800s, she did not have access to the technology we have today that assists people with disabilities in their daily lives. Instead, she had a very dedicated and creative teacher who stuck with Keller throughout her life. This teacher's name was Anne Sullivan. As a result of Sullivan's dedication and Keller's own determination, she learned when many thought she could not.Learning How to CommunicateSullivan helped her learn to communicate by using the resources and abilities Keller did have. Keller could touch, taste, and smell. Sullivan taught her to associate hand movements with words. She would spell words on Keller's hand while having her touch the related object. By associating a physical object with the hand movements, Helen learned the meaning of countless words. Learning to speak was tackled in a similar way. By feeling lips as they moved, Keller learned how to use her lips to form words. Using such innovative techniques and the resources available to her opened whole new worlds for Keller's learning. Sullivan encouraged and mentored Keller, never letting her give up and always believing the best for her.An Inspiration to OthersAnother way Keller learned to communicate was through writing. As an adult, she attended Radcliffe College, which allowed her to advance her education, even though many people doubted her ability to be successful. While she was there, she wrote her autobiography, which told the world about her struggles and accomplishments. She was able to share her story through Braille, a form of writing using raised dots felt with the fingers. Throughout her entire college career, Anne Sullivan was beside her, encouraging Keller and interpreting the words she could not see and the sounds she could not hear. Helen Keller's perseverance and Anne Sullivan's dedication became an inspiration for many children and adults around the world.Helen Keller went on to be a successful author and teacher. She became a mentor to other children and adults living with disabilities. To this day, Keller is remembered for her determination, resourcefulness, and dedication that helped her to overcome obstacles and inspire others.Which details best support the claim that Keller learned to communicate successfully?
