jarptica [38.1K]
<h3><u>given</u><u>:</u></h3>

circumference= 24 feet

<h3><u>to</u><u> </u><u>find</u><u>:</u></h3>

the radius of the circle.

<h3><u>solution</u><u>:</u></h3>

c = 2\pi \: r

r =  \frac{c}{2\pi}

r =  \frac{24}{2 \times \pi}

r = 3.81972

r = 3.8 \: ft

<u>therefore</u><u>,</u><u> </u><u>the</u><u> </u><u>radius</u><u> </u><u>of</u><u> </u><u>the</u><u> </u><u>circle</u><u> </u><u>is</u><u> </u><u>3.8</u><u> </u><u>feet</u><u>.</u>

Which is the solution set of the compound inequality 3.5 x -10&gt; -3 and 8x -9 &lt;39
aivan3 [116]
3.5x-10>-3  add 10 to both sides

3.5x>13  divide both sides by 3.5

x>26/7

x=(26/7, +oo)

...

8x-9<39  add 9 to both sides

8x<48  divide both sides by 8

x<6

x=(-oo,6)

Since this is a compound inequality with AND the solution set will be the union of the two intervals found above.

x=(26/7, 6)

The number of bacteria in a certain population increases according to a continuous exponential growth model, with a growth rate
nikdorinn [45]
Log(2)/log(1.064) ≈ 11.17 . . . . hours

_____
The population can be given by
  p(n) = p₀×1.064ⁿ . . . . where n is the number of hours
You want to find n whe p(n) = 2*p₀.
  2p₀ = p₀×1.064ⁿ . . . . . . . . . . . . substitute the given information
  2 = 1.064ⁿ . . . . . . . . . . . . . . . . . divide by p₀
  log(2) = n×log(1.064) . . . . . . . . take logs to make it a linear equation
  log(2)/log(1.064) = n . . . . . . . . divide by the coefficient of n
