You can plug them each of them into a graphing calculator into y= and then check the table and compare which one is correct. Hope this helps
Summation of 3n + 2 from n = 1 to n = 14 = (3(1) + 2) + (3(2) + 2) + (3(3) + 2) + . . . + (3(14) + 2) = 5 + 8 + 11 + ... + 44 ia an arithmetic progression with first term (a) = 5, common difference (d) = 3 and last term (l) = 44 and n = 14
Sn = n/2(a + l) = 14/2(5 + 44) = 7(49) = 343
Therefore, the required summation is 343.
Answer:
(8,3)
Step-by-step explanation:
because its ON the line and the line is dotted. if the line was solid it would be a solution but it is not because the line is dotted
Answer:
The first store
Step-by-step explanation:
Given data
Let us find the unit cost on each sale
A price for pineapples is $5 for two pineapples
Unit cost per pineapple
=5/2
=$2.5 per pineapple
price for pineapple is $8 for four pineapples
Unit cost
=8/4
=$2 per pineapple
Hence the first store offers the lowest price per pineapple $2.5
