What rule will represent the function, (0,0), (1,1), (2,4), (3,9), (4,16)

a(n) = (n-1)^2

Step-by-step explanation:

Notice that each of the y-values {0, 1, 4, 9, 16, ... } is a perfect square.  Thus,

the rule is a(n) = (n-1)^2.

Check:  if n = 0, is (n-1)^2 = 0?  yes

             if n = 3, is (3-1)^2 = 4?  yes

answer: the 4 kilogram bag

step-by-step explanation: this is because if you divide the number of kilograms into the total it will tell you how much each individual kilogram would be worth. 2 kilos is 7 and change 3 would be around 6 ish and the 4 kilo would be 4.6 and change and the 5 kilos would be like 4.88

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,
