Answer:
I think Quadrant 1. I;m not trying to just answer for the points
Step-by-step explanation:
Answer: 3 min
Step-by-step explanation:
Step 1. Find the constant speed
you walked 1000 feet in 15 min
1000 ft/ 15min=200/3 ft / min
Step 2. Apply the constant speed to the left distance
You already walked 1000 feet and it is total 1200 feet
1200-1000=200 feet left
distance ÷ speed=time
200 ÷ (200/3)=3 min
Hope this helps!! :)

Answer:
1134.62 (THE SUM OF 20 TERMS)
Step-by-step explanation:
First we write out our given information:
a8=2a2
a11=18
an is an arithmetic sequence.
Where here an means the nth term of our sequence.
What does an arithmetic sequence mean? It means to get to the next term in your sequence you add a constant (c) each time:
an+1=an+c
Equivalently:
an+1−an(n+1)−n=c
So an is of slope c (c2 is another constant):
an=cn+c2
Where here c2=a0 (Substitute in n=0 and see why that has to be the case if we let a0 exist)
Now we use the other given information to try to come up with a solution.
Let n=2:
a2=2c+c2
Let n=8, using the above equation we have:
a8=8c+c2=2a2=4c+2c2
Let n=11
a11=18
a11=11c+c2
But a11−a8=(11c+c2)−(8c+c2)=3c
Hence, a11=3c+a8
a11=3c+4c+2c2=18
a11=3c+8c+c2=18
2 bc you can’t write it as a fraction
