We can solve it by Pythagoras Theorem:

C² = 4² + 3²

√(C)² = √(4² + 3²)  note: the rootsquare cancels the power.

C = √(16 + 9)

C = √25

C = 5

What is the 6th term of the geometric sequence where a1 = -4096 and a4 = 64?
Akimi4 [234]
\bf \begin{array}{llccll}
term&value\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
a_1&-4096\\
a_2&-4096r\\
a_3&-4096rr\\
a_4&-4096rrr\\
&-4096r^3\\
&64
\end{array}\implies -4096r^3=64
\\\\\\
r^3=\cfrac{64}{-4096}\implies r^3=-\cfrac{1}{64}\implies r=\sqrt[3]{-\cfrac{1}{64}}
\\\\\\
r=\cfrac{\sqrt[3]{-1}}{\sqrt[3]{64}}\implies \boxed{r=\cfrac{-1}{4}}\\\\
-------------------------------

\bf n^{th}\textit{ term of a geometric sequence}\\\\
a_n=a_1\cdot r^{n-1}\qquad 
\begin{cases}
n=n^{th}\ term\\
a_1=\textit{first term's value}\\
r=\textit{common ratio}\\
----------\\
r=-\frac{1}{4}\\
a_1=-4096\\
n=6
\end{cases}
\\\\\\
a_6=-4096\left( -\frac{1}{4} \right)^{6-1}\implies a_6=-4^6\left( -\frac{1}{4} \right)^5

Negative 1X minus 4X equals -4 minus 4X +4+5
Bond [772]

Answer:

X = - 5

Step-by-step explanation:

The above word problem is mathematically interpreted thus:

-1X - 4X = -4 - 4X + 4 + 5

-5X = - 4 - 4X + 4 + 5

-5X = - 4 - 4X + 9

Collect like terms

-5X + 4X = - 4+ 9

-X = 5

X = - 5
