Same shape just has opposite degrees
9514 1404 393
Answer:
-π
Step-by-step explanation:
The midpoint is the average of the end point values:
(-3π +π)/2 = (-2π)/2 = -π
The midpoint between -3π and π is -π.
The right answer for the question that is being asked and shown above is that: "C. Low." The <span>word that best describes the degree of overlap between the two data sets is low. The overlap is not that big enough or nothing at all. It is just low.</span>
Considering balloon to be an spherical object
Volume of sphere = , where r is the radius of sphere.
After 19 minutes ,If radius of balloon changes from r to R, the Volume changes from V to V'.
V'= ,
As given,rate at which the air leaked out of the balloon (in liters of air per minute) was half of the rate at which Vavilen inflated the balloon.
Also,
Now, again the radius changes from R to r.So, Volume changes from V' to Back to V.
Time taken by the balloon to deflate = 38 minutes
But there is no relation between time and volume of Balloon.
So, we can't predict at which rate balloon is deflating or inflating.Apart from the statement given in Question:
