A rigid transformation takes place when it preserves the shape and size of an object. To add up, it is also called "isometry" which maintain the length of the plane. Included in the rigid transformation are "combinations and reflections." On the other hand, non-rigid transformation involves altering the size.

The rate at which a duck gains weight is proportional to the difference between its adult weight and its current weight. At time

kogti [31]

DB/dt = 1/5(100 - B)
5/(100 - B) dB = dt
-5 ln (100 - B) = t + C
Since B(0) = 20, then
-5 ln (100 - 20) = C
i.e. C = -5 ln 80

Thus -5 ln (100 - B) = t - 5 ln 80
or t = 5 ln 80 - 5 ln (100 - B) = 5 ln (80 / (100 - B))

When the weight = 40 grams
t = 5 In (80 / 100 - 40) = 5 In (80 / 60) = 5 ln (4/3) = 1.438 days
Rate of weight gain = 40 / 1.438 = 27.8 grams per day

When the weight = 70 grams
t = 5 ln (80 / 100 - 70) = 5 ln (80 / 30) = 5 ln (8/3) = 4.9 days
Rate of weight gain = 70/4.9 = 14.27 grams per day.

Therefore, the duck gains weight faster when it weighs 40 grams.

Congruent distance is a term used for distance with equal measurements. EA and EB are congruent; FA and FB are also congruent

I've added as an attachment, the image of the complete question.

From the attached image of the circles, we have the following observations

Points A and B are at the centers of both circles
Point E is at the exact point of intersection of both circles
Point F is also at the exact point of intersection of both circles (opposite point E).

These observations mean that:

The distance from A to E and B to E are the equal (congruent)
The distance from A to F and B to F are the equal (congruent)

Hence,

<em>Distance EA and distance EB are congruent;</em>
<em>Distance FA and distance FB are congruent;</em>
