Step-by-step explanation:

Given the points J (1,-10) and K (7, 2)

From the section formula

$(x,y)=\left(\dfrac{mx_2+nx_1}{m+n}, \dfrac{my_2+ny_1}{m+n}\right)$

The y-coordinates of the point that divides the directed line segment from J to K into a ratio of 5:1 is obtained using the formula:

$y=\dfrac{my_2+ny_1}{m+n}\\m=5, n=1, y_1=-10, y_2=2\\Therefore:\\y=\dfrac{5*2+1*-10}{5+1}\\=\dfrac{10-10}{6}\\=0$

The y-coordinates of the point that divides the directed line segment from J to K into a ratio of 5:1 is 0.

Can someone help me with this

V125BC [204]

Answer: Period = 4

Amplitude = 3

Step-by-step explanation:

Period is the interval of one "cycle" before the pattern repeats.

If you notice that when x = 0, y = -4.

When does the pattern repeat (reach -4 again)?

Answer: when x = 4.

So the interval of one "cycle" is 4 units --> Period = 4.

$Amplitude=\dfrac{Max-Min}{2}=\dfrac{2-(-4)}{2}=\dfrac{6}{2}=\bold{\large\boxed{3}}$
