Answer:
y=5*3^x
Step-by-step explanation:
y=5*3^(-1) =5/3
y=5*3^0=5*1=5
y=5*3^1=5*3=15

We can see that two sides of that triangle area equal
so, their corresponding angle will also be equal
now, we know that
sum of all angles in any triangle is always 180
so, we can get equation as
now, we can solve for x
so, option-C..............Answer
The lateral area would be 298.7 cm².
The lateral area is the area of all of the lateral faces of the pyramid. There are 8 triangles making up the lateral faces. Each has a base of 6.6. The formula for the area of a triangle is
A=1/2bh,
so we still need the height of the triangle.
The height of each lateral triangle is the slant height of the pyramid. The slant height of the pyramid forms a right triangle with the height of the pyramid and the "radius" as it were of the pyramid. Thus we use the Pythagorean theorem:
8²+8²=h²
64+64=h²
128=h²
√128=√(h²)
8√2 = h
Substituting this into our area formula we have:
A=1/2(6.6)(8√2)
We will go ahead and multiply this by 8, since there are 8 lateral faces:
LA=8(1/2)(6.6)(8√2)
LA = 298.7
