5 because you go down 1, right 5 , and move 0
Answer:
Quadratic, Linear, Exponential.
Step-by-step explanation:
You can find the average difference between rows. For example, in the first one, between the ys, it changes by 1, then 3, then 5, then 7. If you look at the changes between these you get 2 each time. Because you had to look at the differences twice, its quadratic. It's linear if you had to look at it once. Exponential you can just see if you can multiply the same constant between each row.
A) If 9 students sharpen 18 pencils in 2 minutes,Then if the time is halved, it will take twice as many men to sharpen 18 pencils.Hence it will take 18 students to sharpen 18 pencils in one minute B) y & 1/x. Then y = K/x where K is our constant of proportionality.Then K = yx. When x = -64 and y = -16 then K = -64 * -16 = 1024. Option DC) When x = 3 y = 8. So for an inverse variation K as calculated from B = 3 * 8 = 24.Then when K = 24 and y = 6; we have 24 = 6x. Hence x = 4. Option A
Answer:
- Seat 1: Peter
- Seat 2: Lia
- Seat 3: Kenny
- Seat 4: Jennie
- Seat 5: Harvey
- Seat 6: Joyce
- Seat 7: Rick
- Seat 8: Mark
Step-by-step explanation:
From Rule 6: Jennie is at Seat 4 and next to Harvey; and by rule 1 (Harvey has a higher seat number than Jennie)
- Seat 4: Jennie
- Seat 5: Harvey
From Rule 2: Peter is across from Harvey.
Since Seat 5 is across from Seat 1
From Rule 7: Peter is next to Lia.
Therefore, Lia can either be in Seat 2 or Seat 8, but by Rule 3 (Neither Joyce nor Lia is in seat 8), therefore, Lia is in Seat 2.
By Rule 5: Lia is next to Kenny, therefore:
From Rule 4: Rick is across from Kenny, and Rick is also next to Joyce.
Seat 7 is across from Seat 3, therefore:
Since Rick is also next to Joyce (and by Rule 3, Joyce cannot be on Seat 8)
Therefore, we have:
Seat 1: Peter
Seat 2: Lia
Seat 3: Kenny
Seat 4: Jennie
Seat 5: Harvey
Seat 6: Joyce
Seat 7: Rick
Since Mark has the remaining seat, Mark is on Seat 8.
