What is the value of the fourth term in a geometric sequence for which a1 = 30 and r = 1/2?.

Mariana [72]

$\bf n^{th}\textit{ term of a geometric sequence}\\\\
a_n=a_1\cdot r^{n-1}\qquad 
\begin{cases}
n=n^{th}\ term\\
a_1=\textit{first term's value}\\
r=\textit{common ratio}\\
----------\\
a_1=30\\
r=\frac{1}{2}\\
n=4
\end{cases}\implies a_4=30\left( \frac{1}{2} \right)^{4-1}$

Answer:

x = 5/4

Step-by-step explanation:

5x - 6 = 4 - 3x

8x - 6 = 4

8x = 10

x = 5/4

The error is that -3x is moved across the = in an incorrect manner. You instead need to add the 3x across the = ending up with 5/4. Adding this across negates the negative which makes it 8x, the rest of the step are as follows.

Need help with math question

Marrrta [24]

ANSWER

$x = 22 \: units$

EXPLANATION

The length of the two chords in the diagram are the same because equal chords are equal distance from the center.

We can see that the two chords are all 12 units from the center.

The line from the center meeting the chords at right angles bisects these chords.

Therefore

$x = 2 \times 11$

$x = 22 \: units$
