Answer:
Step-by-step explanation:
We have been given an equation and we are asked to find the constant of proportionality in the given equation.
If two variables are proportional, there is always a constant ratio between them. This constant is called the constant of proportionality.
Since we know that a directly proportional equation in in form: , where k is constant of proportionality.
Upon comparing our given equation with the directly proportional equation we can see that , therefore, constant of proportionality in our given equation is
.

We have been given that side length of pyramid the square base is 12 cm and its slant height is 10 cm. We are asked to find the height of the pyramid.
We will use slant height of a pyramid formula to solve our given problem.
,where,
s = Slant height,
h = Height,
a = Each side of square base.
Upon substituting our given values in above formula, we will get:
Switch sides:
Let us square both sides:
Now we will take positive square root of both sides.
Therefore, the height of the pyramid is 8 cm and option 'b' is the correct choice.
