Lerola and her younger sister Kiara are jogging around a circular track. Lerola jogs far enough from the center of the circle th

xxTIMURxx [149]

Circumference of circular track, C = 0.5 miles = 0.5×5280 feet = 2640 feet.

We know, circumference in circle is given by :

$C = 2\pi r$

( Here, r is radius i.e distance of centre from track )

Putting values in above equation :

2 × 3.14 × r = 2640

6.28 × r = 2640

r = 420.38 feet

Therefore, distance between centre and track is 420.38 feet .

Hence, this is the required solution.

Researchers recorded that a certain bacteria population declined from 120,000 to 200 in 36 hours. At this rate of decay, how man

quester [9]

Answer: There will 486 bacteria in 31 hours.

Step-by-step explanation:

The population decay in bacteria is exponential.

Exponential function : $y=Ab^x$ , where A = initial population, b multiplication decay factor, t= time:

As per given:

Initial population: $A=120,000$

After 36 hours, population = $120000(b^{36})=200$

Divide both sides by 120,000 we get

$b^{36}= 0.00167$

Taking natural log on both sides , we get

$36\ln b=\ln 0.00167\\\\\Rightarrow\ b=e^{\left(\frac{\ln0.00167}{36}\right)}=0.83724629\approx0.8372$

At x= 31,

$y=120000(0.8372)^{31}=120000\times0.00405234\approx486$

Hence, there will 486 bacteria in 31 hours.
