Answer:

\sqrt{7}

Step-by-step explanation:

Using the rule of radicals

\sqrt{\frac{a}{b} } ⇔ \frac{\sqrt{a} }{\sqrt{b} }

\frac{\sqrt{21} }{\sqrt{3} } = \sqrt{\frac{21}{3} } = \sqrt{7}

Write the explicit formula that represents the geometric sequence-2, 8, -32, 128
maks197457 [2]
Well,  since we know is a geometric sequence, we can always get the common ratio  of it by simply dividing one value by the one behind it... so let's do so, with say hmm -32 and 8  -32/8 = -4  <-- our common ratio

the first term is -2

\bf n^{th}\textit{ term of a geometric sequence}\\\\&#10;a_n=a_1\cdot r^{n-1}\qquad &#10;\begin{cases}&#10;n=n^{th}\ term\\&#10;a_1=\textit{first term's value}\\&#10;r=\textit{common ratio}\\&#10;----------\\&#10;a_1=-2\\&#10;r=-4&#10;\end{cases}\implies a_n=-2(-4)^{n-1}

Help me please i need it rn
umka2103 [35]

Step-by-step explanation:

Multiply 12600 by -3/4 to determine the amount earned.

*12600 can be put over 1.

<u>Multiply:</u>

\frac{12600}{1}  \times  \frac{ - 3}{4}  =  \frac{37800}{4}

<u>Simplify by dividing the fraction by 4:</u>

\frac{ - 37800 \div 4}{4 \div 4}  =  \frac{ - 9450}{1}
