Answer:

135

Step-by-step explanation:

Using the given recursive rule, then

a_{2} = a_{1} (- 9) = \frac{5}{3} (- 9) = - 15

a_{3} = a_{2} (- 9) = - 15 × - 9 = 135

take 25% off the original. now take off an additional 10% and calculate the new sales cost of this item. what is your total perc
Aneli [31]

x = original price, or 100%

if we take off 25% from 100% what's left is 75%, that's the discounted price.

let's then take 10% of that.

\bf \begin{array}{|c|ll} \cline{1-1} \textit{a\% of b}\\ \cline{1-1} \\ \left( \cfrac{a}{100} \right)\cdot b \\\\ \cline{1-1} \end{array}~\hspace{5em}\stackrel{\textit{75\% of "x"}}{\left( \cfrac{75}{100} \right)x\implies 0.75x} \\\\[-0.35em] ~\dotfill\\\\ \stackrel{\textit{10\% of 0.75x}}{\left( \cfrac{10}{100} \right)0.75x\implies 0.075x}~\hfill \stackrel{\textit{total percent savings}}{0.75x-0.075x\implies 0.675x} \\\\[-0.35em] ~\dotfill

\bf \stackrel{\textit{changing that to percent format}}{0.675\cdot 100\implies 67.5\%}

Which is the greatest common factor of the expression below?<br> 32a²b2 + 36a²c2 – 16ab3
yKpoI14uk [10]

Answer:

Step-by-step explanation:

32a²b²  = 2 * 2*2*2*2 * a² * b²

36a²c² = 2 * 2 * 3 * 3 * a² * c²

16ab³  = 2 * 2 * 2* 2 * a * b³

Greatest common factor =  2*2*a = 4a

32a²b² + 36a²c² - 16ab³ = 4a*(8ab² + 9ac² - 4b³)
