Answer:
64 units squared
Step-by-step explanation:
If you put the points on a graph you can see the shape is a trapezoid. The left and right sides are the bases, the bottom is the height. The area formula is to average the bases and times by the height. see image. You could do a lot of distance formula and slope calculations, but on the graph you can count the squares to find side lengths.
Answer:
Step-by-step explanation:
we know that
The total area or surface area of the regular pyramid is equal to the area of the triangular base plus the area of its three lateral triangular faces
so
step 1
Find the area of the triangular base B
Is an equilateral triangle
Applying the law of sines
step 2
Find the area of the lateral triangular faces
Find the height
Applying the Pythagorean Theorem
Find the area of the lateral triangular faces
therefore
The total area is
Answer:
and
Step-by-step explanation:
The function is given as
<em>to find inverse, we follow the steps shown below:</em>
<em>1. write "y" in place of "f(x)"</em>
<em>2. interchange "x" and "y"</em>
<em>3. solve for the new "y"</em>
<em>4. replace y with f^-1(x)</em>
<em />
Let's do this:
These 2 are the inverse functions.
