Look at the pentagonal numbers. Use finite differences to determine which function represents the pattern. f(x) = 1.5x - 0.5x

f(x) = 1.5x^2 + 1.5x

f(x) = 1.5x^2 - 0.5v

f(x) = 0.5x^2 + 0.5x

the answer is 0.5 mpm

step-by-step explanation:

the line goes half way through the square each time (which is 0.5 or half of course) so that would mean its 0.5 mpm.

y=1/4x-4

step-by-step explanation:

3/20

step-by-step explanation:

well, there are 20 outcomes, and 3 of them you want. so, 3/20

60: 45 =12: 9 =4: 3 so the answer is 4: 3
