Sandra already owns 1 hairband, and additional hairbands are priced at 1 for a dollar. How much money does Sandra need to spend on new hairbands inorder to own a total of 41 hairbands?

$40 dollars

Step-by-step explanation:

$1 (how much hairbands cost) x 40 (how many she needs to make 41 because she already owns 1 hairband) = $40

(n^3 - n)

= n(n-1)(n+1)

since it is divisible by 3 and 2 ,because it is a multiple 3 consecutive number

if, n-1 is odd then n+1 is also odd, then it is a multiple of 9

but if, n-1 is even then n+1 is also even, then it is a multiple of 4

so, largest multiple = max(9*2, 4*3) = max(18, 12) = 18

(0,,,0)

step-by-step explanation:

the table of x and y values is shown in the attached pic(part of question)

we have to decide according that graph

given points are (0, 0) (–1, 0), (2, 0)

when we graph these points on graph they show an increasing line as shown in the attached pic
