The equation is
R=100(1/2)^(d/5)
After one day the remaining is
R=100×(1÷2)^(1÷5)
R=87.06 remaining
It decreased by 12.94 (100−87.06)
So the daily percent of decreases is 12.94%
Answer:
C=31.41592654
Step-by-step explanation:
C=2πr
r=5
C=2π(5)
Therefore C= 10π or C=31.41592654
Yes, it’s a solution. First you plug in -2 for x and -4 for y. 5(-2) is -10 and -2(-4) is positive 8. Add -10 to 8 and you’ll get -2 which is what you should get if the ordered pair is a solution. Hope this helps
<span>It is estimated that 5000 live bacteria existed in the sample before treatment. After each day oftreatment, 40% of the sample remains alive. Which best describes the graph of the function thatrepresents the number of live bacteria after x days of treatment? f(x) = 5000(0.4)x, with a horizontal asymptote of y = 0 f(x) = 5000(0.6)x ...</span><span>
