Hey guys please help

zimovet [89]

Answer:

$7.98 \:m$

Step-by-step explanation:

Area of a triangle is base times height divided by 2.

$A= \frac{bh}{2}$

$69.6= \frac{b \times 17.45}{2}$

$69.6 \times 2= b \times 17.45$

$139.2=b \times 17.45$

$\frac{17.45b}{17.45}=\frac{139.2}{17.45}$

$b=\frac{2784}{349}$

$b=7.97707$

The appropriate unit is meters.

anyanavicka [17]

If Mike has 15.68 pounds of aluminum, and he wants to take at least 50 pounds of said item, then he would need to collect 34.32 more pounds of aluminum. (50 - 15.68 = 34.32)

Find the sum of a finite geometric sequence from n=1 to n=8, using the expression -2(3)^n-1

MissTica

$\bf \qquad \qquad \textit{sum of a finite geometric sequence}
\\\\
S_n=\sum\limits_{i=1}^{n}\ a_1\cdot r^{i-1}\implies S_n=a_1\left( \cfrac{1-r^n}{1-r} \right)\quad 
\begin{cases}
n=n^{th}\ term\\
a_1=\textit{first term's value}\\
r=\textit{common ratio}
\end{cases}
\\\\\\
\sum\limits_{n=1}^{8}~-2(3)^{n-1}~~
\begin{cases}
n=8\\
a_1=-2\\
r=3
\end{cases}\implies S_8=-2\left( \cfrac{1-3^8}{1-3} \right)
\\\\\\
S_8=\underline{-2}\left( \cfrac{1-6561}{\underline{-2}} \right)\implies s_8=1-6561\implies S_8=-6560$
