What is the vertex of f(x)=(x+3)2+4?

Answers

Answer:

Below.

Step-by-step explanation:

f(x)  =  a(x - j)^2  +  k is the standard vertex form where (j, k) is the vertex,

f(x) =     (x + 3)^2 + 4

Comparing this to the standard form we see that:

vertex =  (-3, 4)

Tia rounds a number, x , to 3 sf. The result is 9.73. Write the error interval for x in the form a ≤ x < b .

Answers

Answer: 9.725  ≤ x ≤ 9.734

Step-by-step explanation:

We know that 9.73 is rounded, then we need to look at the next digit after the last one of 9.73, this would be the third digit after the decimal point.

We know that if this digit is smaller than 5, then we round down.

Then the largest number that can be rounded down to 9.73 is:

9.734

Now we want to find the smallest number that can be rounded up to 9.73

We know that if the next digit is 5 or bigger, then we round up.

Then the number 9.725 is rounded up to 9.73

And this is the smallest number that can be rounded up to 9.73

Then the error interval is:

9.725  ≤ x ≤ 9.734

A pendulum's first swing has an arc of 36 inches. As the pendulum swings back and forth, the arc length for each successive swing is 95% of the previous swing. If this pattern continues, at which swing of the pendulum will the length of the arc be less than 27 inches? A. 5th B. 6th C. 7th D. 9th

Answers

Answer:

7th

Step-by-step explanation:

Given :

Arc length on first swing = 36 inches

After successive swing, arc length decreases by 95%

Length on 2nd swing = 0.95 * 36 = 34.2

Length on 3rd swing = 0.95 * 34.2 = 32. 49

Length on 4th swing = 0.95 * 32.49 = 30.8085

Length on 5th swing = 0.95 * 30.8085 = 29.268075

Length on 6th swing = 0.95 * 29.268075 = 27.80467125

Length on 7th swing = 0.95 * 27.80467125 = 26.4144376875

26.4144376875 < 27

Hence, length falls below 27 on 7th swing

Lily and Wilder live 810 miles apart. If they leave at the same time and drive towards each other with Lily driving at 55 mph and Wilder driving at 80 mph, after how many hours will they meet?

Answers

Given:

Distance between Lily and Wilder = 810 miles

They drive towards each other with Lily driving at 55 mph and Wilder driving at 80 mph.

To find:

After how many hours will they meet?

Solution:

Lily driving at 55 mph and Wilder driving at 80 mph towards each other. So, the relative speed is:

Relative speed [tex]=(55+80)\text{ mph}[/tex]

                         [tex]=135 \text{ mph}[/tex]

We know that,

[tex]Time=\dfrac{Distance}{Speed}[/tex]

[tex]Time=\dfrac{810}{135}[/tex]

[tex]Time=6[/tex]

Therefore, Lily and Wilder will meet after 6 hours.

True or False? The measure of a tangent-chord angle is twice the measure of
the intercepted arc inside the angle.

Answers

The statement made which says the tangent - chord angle is twice the measure of the intercepted arc inside the angle is FALSE.

According to the angle theorem, the angle formed by the intersection of the chord and tangent on a circle is twice the measure of the intercepted arc.

This means that the intercepted arc is twice the measure of the angle formed and not the other way round.

Therefore, the statement is False because the intercepted arc is twice the measure of the angle formed by the intersection of the chord and the tangent on the circle.

Thank you!Learning a language opens doors to a world of opportunity. Of course, in order to really benefit from your studies, youll need to do more than just complete assignments. Youll need to set habits that will tie you to French and its cultures even beyond the classroom. Students who become lifelong learners of French have some basic characteristics and habits that you should develop if you want to get the most from your experience learning French. Here are some of them:Lifelong learners:Have friends with whom they regularly converse in the target language. (This could be friends in school, neighbors or friends in the community.)Regularly get information from target language sources, such as newspapers, magazines, Internet, French related news groups (with parents approval), TV programs, radio, etc.Participate in activities of the target culture (celebrating holidays, seeing movies or plays of/in the target culture, preparing or eating dishes from the target culture, reading books or magazines from the target culture, etc.)Someone who has developed these habits is on the way to becoming a lifelong learner. These types of habits reinforce a strong connection to the language and culture and develop a love and better understanding of that culture.Think for a minute about the resources available. Do you have friends who are native French speakers? Do you ever watch French channels on television? You can probably think of several online sources. Maybe you have some stores or restaurants in your community that are run or frequented by French speakers. Also think about when you could do this on a regular basisremember that its setting the habits that will make the most difference.Using the table below as a guideline, write what you plan to do. For the Language or Culture Resources column, try to identify three different resources: 1. A friend or contact, 2. An information source, and 3. A cultural activity. In the What I Will Do column, describe as specifically as you can what you will do. And in the When I Will Do It column, write when you plan on doing these activities. See the sample below to see how you might fill out your own table.You will have opportunities to follow up and report on your regular practice of engaging French resources close to home. You will be asked in a follow up assignment to report on what you have done. If you are still unsure where to begin, ask your teacher for additional ideas that can help get you started. Regardless of how you go about making your French cultural connection, be sure to make a plan and to think about a longer-term strategy for getting the most from your time with your chosen resources.
