Apples are on sale for $3.12 per kilogram. is the total cost of the apples proportional to the total mass?

Yes

Tc = 3.12m

Therefore, total cost of apple is directly proportional to the total mass with a proportionality constant of 3.12.

Step-by-step explanation:

The total cost of the apples is proportional to the total mass. The product of the mass and the cost per mass ($3.12) gives the total cost.

It can be shown using the equation below

Tc = c×m

Where Tc = total cost

c = cost per unit mass

m = total mass in kilogram

Tc = 3.12m

Therefore, total cost of apple is directly proportional to the total mass with a proportionality constant of 3.12.

i want to die

what the hell man, i just want the points lol

arithmetic sequence

step-by-step explanation:

given that a sequence has terms as

19, 15, 11,

this is represented on a graph

the pattern indicates that the sequence is an arithmetic sequence with i term

a=19 and common difference d =-4

any general term

thus the sequence is reduced by 4 for each successive term starting from 1 and nth term is

24-5n.

first negative term would start after 5th term

5th term =24-25< 0

from 5th term onwards the sequence would be negative.
