The equation of the polar curve
is an even cosine function.
<h3>Polar curves</h3>
In geometry, polar curves are curves that are represented by the polar coordinates such that they are drawn around a fixed point
The equation of the polar curve is given as:

To graph the polar curve, we make use of the following representations:
- r represents the y-axis
represents the x-axis
Using the above representation, we can graph the polar curve
See attachment for the graph that represents

Function is given in the form: f ( 2 ) = 12. There is x = 2, which means the presence of bacteria after 2 hours.
Answer : C) The total number of the bacteria present in the sample after 2 hours is 12.
The solution
m = s + 5
<span>m - 4 = (3s) - 3 </span>
<span>(s + 5) - 4 = 3s - 3 </span>
<span>s + 1 = 3s - 3 </span>
<span>s = 3s - 4 </span>
<span>-2s = -4 </span>
<span>s = 2 </span>
<span>m = 7 </span>
<span>Check this: </span>
<span>m - 4 = 3s - 3 </span>
<span>7 - 4 = 3(2) - 3 </span>
<span>3 = 6 - 3 </span>
<span>3 = 3 </span>
<span>So Sandy is 2 and Megan is 7.</span>
2.56 times 0.03 is 0.0768 then round to hundredth is 0.08 i think
