Answer:
Step-by-step explanation:
The equation 
is a <em>linear equation</em>. By definition, the independent term on this equation (that is, the number that is not being multiplied by 
) is the <em>y-intercept</em>, which is a fancy way of saying "the point where the line crosses the y-axis".
By looking at the equation, we know that our y-intercept is <em>c. </em>By looking at the graph, we can see that the y-intercept is -3. Therefore, 
and we get the complete version of our linear equation:
Now, looking at the graph we can see that the point 
lies on the line of the equation, which means that the point is a solution to our equation. All we have to do is replace and 
by the values of the given point (which are 
and 
, respectively), and then solve for :
And we are done!

A tetrahedron is a triangular pyramid. It has four triangular faces and four vertices.
In the question, we are told that the length of the edges are all equal = 20m and the length from one corner to the center of the base = 11.5m
We sketch a diagram of a tetrahedron with the given measurement as shown below
To find the height, we will use the Pythagoras theorem
20² = h² + 11.5²
h² = 20² - 11.5²
h² = 267.75
h = √267.75
h = 16.36 (rounded to two decimal places)
