alekssr [168]

Answer:

Step-by-step explanation:

Common ratio (r) = 2nd term / 1st term = 15/3 = 5

Recursive formula:

a_{n}=a_{n-1}*r \\\\a_{n}=a_{n-1}*5\\=5a_{n-1}

Explicit formula:

a = first term = 3

a_{n}=ar^{n-1}\\\\a_{n}=3*(5)^{n-1}\\

Can somebody please help me find the volume of this triangular prism?
Bas_tet [7]

Check the picture below.

the volume of the prism will simply be the product of the triangular area and its length, it has a length of 8, thus

\bf \stackrel{\textit{area of a triangle}}{A=\cfrac{1}{2}bh}~~ \begin{cases} b=9\\ h=6 \end{cases}\implies A=\cfrac{1}{2}(9)(6)\implies A=27 \\\\\\ \stackrel{\textit{volume of the triangular prism}}{V=27\cdot 8}\implies V=216
