Answer:

Step-by-step explanation:

Polygon #1

40 + 33 + 23 + 25 + 30 = 151 ft

CD = 175 - 151 = 24 ft

Polygon #2

65 + 57 + 66 = 188 ft

SV = 259 - 188 = 71 ft

If n and k are positive integers, is n divisible by 6 ? (1) n = k(k + 1)(k – 1) (2) k – 1 is a multiple of 3.
xz_007 [3.2K]

Answer: yes, it is

Step-by-step explanation:

A number is divisible by 6 if it is divisible by 2 and 3 simultaniously.

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

If k-1 is a multiple of 3, n is divisible by 3, so one of the requirements is ok.

Now, if k-1 is a multiple of 3, it can be even or odd.

if k-1 is even, then it is divisible by 2 and as it is divisible by 3 as well, n is divisible by 6

if k-1 is odd, then k and k+1 is even, hence, divisible by 2.

As n = k(k+1)(k-1), n is also divisible by 6.

What are the zeros of the graphed function
Sphinxa [80]

Answer:

Step-by-step explanation:

The zeros are where the graph intersects the x-axis

x = 0

x = 2

x = 4

------------------------

Extra Credit

Note x = 2 is a double zero since it touches, but does not cross the x-axis

The equation is

y = -x(x - 2)²(x - 4)
