Aphone company charges for service according to the formula: c(n)=10+0.08n, where n is the number of minutes talked and c(n) is the monthly charge, in dollars what is the slope?

The slope of a linear equation is the coefficient that you find in front of the variable.

In this case the variable is n, and its coefficient is 0.08, so that's the slope.

15.5

step-by-step explanation:

5

∑

n = 1

substitute n = 1, 2, 3, 4, 5 and sum the terms

= + + + 2² + 2³

= 0.5 + 1 + 2 + 4 + 8

= 15.5

(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
