Starting at 6:00 a.m., Lin spent a day hiking through a canyon. This graph shows her elevation (in meters) at some different times. Negative values of x represent times earlier than noon, and positive values of x represent times later than noon.
Please help me with this

Starting At 6:00 A.m., Lin Spent A Day Hiking Through A Canyon. This Graph Shows Her Elevation (in Meters)

Answers

Answer 1

Answer:

First, we know that the 0 in the horizontal axis corresponds to the noon.

Then:

a) Lin's elevation at noon in meters.

We need to see the elevation when x = 0.

This is the point that is just on top of the y-axis, we can see that when x = 0, we have y = 6.

Then at noon, her altitude was 6 meters.

b) At 8:00 am, her elevation was 2m

Remember that the x-component represents time, and x = 0 represents the noon.

8:00 am is 4 hours before noon, then 8:00am is represented with x = -4

and at this time her elevation is 2m, then y = 2.

This means that the point that represents this is (-4, 2)

c) At 4:00 pm Lin was at sea level (her elevation was 0m)

Same reasoning than before: x = 0 is the noon, then 4:00 pm is four hours after this, then 4:00 pm is represented with x = 4.

And here her altitude is 0m, then y = 0.

This point is written as (4, 0)

d) Here we can see that at 6:00 am her elevation was negative, and at 4:00pm her elevation is 0.

And we know that:

0 > negative numbers.

Then her altitude increased in this interval of time.

Answer: positive, linear association

Step-by-step explanation: that is the answer, because the dots are rising up in a slope

Answer:

The answer is simple: Positive, linear association. Why is that? It is moving from left to right, increasing as it goes. That is a sign of a positive slope. And, this has a linear association because the points are jumbled together in a clear direction, so we know that we can place a line of best fit.

Dorcas walks a distance of 18 km from home to school at a speed of 6km/h how long does she take to arrive at school?

Answers

Time = distance / speed

Time = 18 km / 6 know

Time = 3 hours

Answer:

[tex] \bf \huge 3 \: hours[/tex]

Step-by-step explanation:

Given that :

Dorcas walks a distance of 18 km from home to school at a speed of 6km/h.

to find :

how long does she take to arrive at school ?

formulas used :

time = distance / speed

let us assume :

time = t

explanation :

⟼ distance = 18 km

⟼ speed = 6 km/h

⟼ t = distance / speed

⟼ t = 18/6 h

⟼ t = 3h

⟼ time = 3 hours.

∴ dorkas take 3 hours. to arrive at school.

Answer:

For whatever reason, there are different formats for simple linear equations. I prefer the slope-intercept form; at times, the point-slope form is helpful; some textbooks strongly prefer what they sometimes call the "intercept" form, which is often (though not always) given as being "Ax + By = C", so-called because the intercepts are at \small{ \left(0,\,\frac{C}{B}\right) }(0,

Your brother is 13 your age. Your sister is 4 years older than your brother. Your sister is 9 years old. Write and solve an equation to find your age a.

An equation is

You are

Answers

answer:

if you rounded it the answer is 15 years old!

step-by-step explanation:

when know that your sister is 9 years old, so lets start off with that. because your sister is 4 older then your brother then that must mean that you brother is 5 years old

9-4

= 5

we also know that you brother is 1/3 your age so divide 5 by 1/3 or .33

5/ .33

= 15.15

but since it looks like we only need the whole number. just round down to 15 since your age is not close enough to round up to 16

Read the speech and answer the question. Voluntourism: An Opportunity Too Good to be True A Speech to the Student Body of Evergreen High [1] Picture this: It's Spring Break, and you fly off to some country where there's lush rainforests and beautiful, blue coastlines to explore. There's also people in need, so you decide to blend your vacation with volunteering. Volunteering as a tourist, or voluntourism, seems like a great way to explore new regions and help people at the same time. However, this "volunteer plus travel" experience can actually harm local communities. While many teens might view traveling and volunteering abroad as a worthwhile adventure, there are more genuine and effective ways to make a difference. [2] Most would agree that volunteering in general is a worthy use of time. However, what if you found out the children you are "helping" are actually being kept in poor conditions so voluntourists will spend money to come to the local area? Dale Rolfe, a supporter of ethical voluntourism, explains the shocking reality that "Animal sanctuaries and orphanages are often manufactured for the voluntouristencouraging a cycle of exploiting the very animals and children the volunteers are trying to help." [3] Proponents of the "volunteer plus travel" experience also argue that traveling to new places builds character and is a valuable way to learn about different cultures. With voluntourism, however, participants often pursue experiences that are all about them. For example, they sign up to build a school for a gold star on their resume, but they have no real building skills and take jobs away from local construction workers (Schulten). Or, they arrive to teach English but instead take selfies with the locals. One world traveler and ethical voluntourist believes voluntourism "can perpetuate small minded views of the world by taking insulated, fake, and structured experiences and selling them as unabridged and eye opening" (Carlos). The voluntour experience is a mirage. The voluntourist's eyes are not opened to real life at the destination, and lasting change is not achieved. [4] If you want a genuine experience where you can see a lasting impact, there are better options than voluntourism. You can volunteer in your local community. Give an hour every week to your town's animal rescue. Serve monthly dinners to the homeless. Be a reliable, positive influence on a child who needs a mentor. Studies show that volunteering and forming lasting relationships with those you help has a positive impact on your physical and emotional health. In fact, blood pressure is reduced, memory is improved, and rates of depression are reduced (Michaels). [5] There is another reason to look into alternatives to voluntourism. Did you know the average "voluntour" travel package costs $3,400 (Rolfe)? Could that travel money be better spent? If the world's citizens are your passion, it could go to an international organization. If you care about education, your funds can be used to buy books for students in faraway lands. If you want villagers to have clean water, contribute funds to local efforts to dig wells. If you want to experience a different culture, travel to the country as a guest, and learn from the locals how you can best help them after you've returned home. But do not voluntour. [6] In reality, there are better ways to make a difference. Voluntourism might appear to be an adventure that blends travel and helping others, but it does little except provide a costly, superficial experience that might actually do more harm than good. So, volunteer where you are most needed-at home, where you can stay to see the job through and form genuine, lasting relationships. Choose a beautiful coastline closer to home and send the travel money you saved to an international organization that will put it to good use. Whatever you do, don't turn someone else's hardship into your vacation. Which paragraphs address the counterclaim of the argument?
