Answer:
I'm pretty sure it's +(-6).
Step-by-step explanation:
Basically for these, you find the slope. The slope equation is y1-y2/x1-x2.
Pick two points.
I'll just do (1,15) and (2,9).
15-9/1-2 = 6/-1 = -6.
I don't know if you were taught it this way, but my math teacher always told us that the rate of change had to be positive.
So you'd say the rate of change is +(-6), not -6.
Hope that sorta helped lol

Answer:
The other sides of triangles are 8.72 in and 8.72 in
Step-by-step explanation:
In a triangle ABC. Please find the attachment for figure.


Side BC=a = 10 in
Using sine law of trigonometry,

Substitute the given value into formula.


Cross multiply and we get

in
It is a isosceles triangle. Therefore, b=c=8.72 in
Hence, The other sides of triangles are 8.72 in and 8.72 in
Let the side length of the square be x, then A = x^2
but diagonal (z) = sqrt(2x^2)
z^2 = 2x^2
x^2 = 1/2 z^2
Thus, A = 1/2 z^2
dA/dz = 1/2 (2z) = z
The rate of change is z.
When z = 4, the rate is 4.
