2.What is the solution of the solution of the equation 5^3x=15? Round to the nearest ten thousandth.

sveta [45]

Hmm
remember
$a^c=b$ can translate to $log_a(b)=c$
so

$5^{3x}=15$ can translate to $log_5(15)=3x$
divide both sides by 3
$(1/3)log_5(15)=x$
$log_5(15^{1/3})=x$
use calculator, if you can't use change of base formula to do it
$log_a(b)= \frac{log_c(b)}{log_c(a)}$ so
$log_5(10^{1/3})= \frac{log_{10}(15^{1/3})}{log_{10}(5)}=x$
evaluate using base 10 on your calculator
0.560869=x

How much would you pay for 115 minutes?

melomori [17]

Answer:

Answer is A - $43.40

Step-by-step explanation:

For 115 minutes, we would be in the middle territory and so will need to use the middle equation:

$c(x)=0.35x+3.15\\c(115) = 0.35(115)+3.15\\c(115)=40.25+3.15\\c(115)=43.40$

Was this a fair test? is it representative of the effectiveness of the test substance

ArbitrLikvidat [17]

No. The test is not a fair test. The test is artificial. Testing the disinfectant against bacteria in a test tube is not representative of the effectiveness of the disinfectant against microbes in the environment. Test tube tests test for efficacy. Effectiveness can only be tested out in the environment.
