How to find the surface area of a triangular prism

1 answer:

5 0

Answer: Surface area of a triangular prism = 2*Area of Base (triangle) + Perimeter of Base (triangle)*Height

Step-by-step explanation: The sum of the areas of all the sides of the triangular prism is equal to the surface area. Thus, if you add all the areas of the sides you will get the surface area. The equation above is a faster way to do it.

Write an<br> i explicit formula for an, the nth term of the sequence 200, 40, 8, ....

Ugo [173]

Answer:

$T_n = 200 * (\frac{1}{5})^{n-1$

Step-by-step explanation:

Given

$Sequence: 200,40,8$

Required

The nth term

The given sequence is a geometric sequence.

So, first we identify the first term

$a = 200$

Calculate common ration

$r = \frac{40}{200}$ or $r = \frac{8}{40}$

$r = \frac{1}{5}$

So, the nth term is:

$T_n = ar^{n-1$

$T_n = 200 * (\frac{1}{5})^{n-1$
