Answer:
Remi needs 15 cm of wood to be cut for the shelf.
Step-by-step explanation:
We have drawn the triangle for your reference.
Now Given:
Base measure (BC) =30 cm
Slant height (AB) = 24 cm
Slant height (AC) = 18 cm
Also Given horizontal shelf halfway between the base and the top.
In the triangle drawn horizontal shelf is denoted by DE.
We need to find the measure of DE.
Now we know that horizontal shelf halfway between the base and the top.
Hence by Midpoint theorem which states that;
"The segment joining two sides of a triangle at the midpoints of those sides is parallel to the third side and is half the length of the third side."
Substituting the value we get;
Hence Remi needs 15 cm of wood to be cut for the shelf.
Answer:
The vertex form for a parabola is given by this expression:
By direct comparison we see that for this case:
And we know from the general expression that the vertex is:
So then the vertex for this case is:
Step-by-step explanation:
For this case we have the following function:
And we need to take in count that the vertex form for a parabola is given by this expression:
By direct comparison we see that for this case:
And we know from the general expression that the vertex is:
So then the vertex for this case is:
