Tim uses his lorry to deliver turf. You can use this graph to find the delivery costs for different distances. 100- 80- For each delivery, there is a fixed charge plus a charge for distance. a) How much is the fixed charge? E 60 Delivery cost (E) 20 Tim makes two deliveries of turf The distance of one delivery is 20 miles m e than the distance of the other delivery. ) What is the difference between the two delivery costs? 3 (2) Total marks: 3 O 10 20 30 40 50 Distance (miles

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.

the answer is 13 cm

step-by-step explanation:

for volume, add base x height x width
