Answer:
![62.4$ cm^2](https://tex.z-dn.net/?f=62.4%24%20cm%5E2)
Step-by-step explanation:
The net of the triangular pyramid is attached below.
Since each of the faces is an equilateral triangle of side 6cm, the base of the pyramid will also be an equilateral triangle of side lengths 6cm .
In the equilateral triangles
Therefore, the surface area of the pyramid formed from the net shown
= 4 X Area of One Triangular Face
![=4 (\frac12 \times bh)\\=4 (\frac12 \times 6\times 5.2)\\=4(15.6)\\=62.4$ cm^2](https://tex.z-dn.net/?f=%3D4%20%28%5Cfrac12%20%5Ctimes%20bh%29%5C%5C%3D4%20%28%5Cfrac12%20%5Ctimes%206%5Ctimes%205.2%29%5C%5C%3D4%2815.6%29%5C%5C%3D62.4%24%20cm%5E2)
If you marked the one on the left then you are correct. The initial value for this exponential function is 2. That is where x is 0 and y have some value. You could do this mathematically by replacing the x in the equation with a 0 and solving for y. Anything, whether it be a variable or a number, raised to the power of 0 is 1. y = 2 then when you raise 3 to the 0 power because 3^0 = 1 and 2*1 = 2.

I just took the quiz.
Answer:
-2y-18= 0
Then solve for y
Step-by-step explanation:
There are 25 identical squares arranged inside the 5 by 5 square matrix. From the drawing it's evident that the length of the side of any one of the smaller squares is just 1. Thus, the perimeter of this one smaller square is P = 4(1), or 4.
The desired perimeter is 4.
