Answer:

D is the answer.

$16x {}^{2} - 81 = 0 \\ (4x - 9) \times (4x + 9) = 0 \\$

$4x - 9 = 0 \\ 4x = 9 \\ x = \frac{9}{4} \\ or \\ 4x + 9 = 0 \\ 4x = - 9 \\ x = - \frac{9}{4}$

Rachel took a two-day road trip last weekend. She drove 65 miles less on Sunday than she did

Sav [38]

Answer:

I believe the answer is 186.5 miles were driven on Sunday and 251.5 miles on Saturday. The total amount of miles driven was 483 miles

Step-by-step explanation:

So if Rachel drove 65 miles less than she did on Saturday and Twice the miles she drove on Sunday was 373, we would divide 2 from 373 which gives us 186.5 miles on Sunday. Because she drove 65 miles less on Sunday than she did Saturday, then she drove 251.5 miles on Saturday. If you needed the total amount of miles she drove then we would just add 186.5 miles to 251.5 miles to get an answer of 483 total miles.

A scientist counts 25 bacteria present in a culture and finds that the number of bacteria triples each hour. The function y = 25

Ksju [112]

$y = 25\cdot~3^x\\ \\ 1170 = 25\cdot~3^x\\ \\ \frac{1170}{25} = 3^x\\ \\ \frac{243}{5} = 3^x\\ \\ log\ \frac{243}{5} = log~3^x\\ \\ log~243-log~5=x~log~3\\ \\ 
 log~3^5-log~5=x~log~3\\ \\ 5~log~3-log~5 = x~log~3\\ \\ 5(0,48)-0,70= 0,48x\\ \\ 2,4-0,7 = 0,48x\\ \\ 1,7=0,48x\\ \\ x=\frac{1,7}{0,48}\\ \\ \large{\boxed{x=3,54\ h}}$
