Answer:
B
Step-by-step explanation:
Radioactivity can be said to be a physics or chemistry topic which involves calculating the value of a substance after a period of time using power of exponents and log.
Projectile motion can be well explained using trigonometry in mathematics and this makes it easier during calculations.
<h3>Radioactivity</h3>
This is another non-math topic where the knowledge of a math topic will come in handy in order to explain it
In radioactivity, we are either calculating the half-life of a sample, the amount of a sample left after a period of time or even the the disintegration constant of the sample. This is made possible through the knowledge of exponential increase or decrease as well as logarithmic functions.

Based on the calculations, the length of side AB is equal to 13.93 units.
<h3>How to find the length of AB?</h3>
Since the points of tangency are at A and B, we would determine the side length of the point lying between side A and D as follows:
AM = AD - BC
AM = 7 - 2
AM = 5 units.
Now, we can determine the length of side AB by applying Pythagorean's Theorem:
AB² = BM² + AM²
AB² = 13² + 5²
AB² = 169 + 25
AB = √194
AB = 13.93 units.

X=21
-10x= -210
------- -------
-10 -10
X= 21
The line under the -10x and -210 is a division line you would divide -10x by -10 which would cancel out the -10 and divide -210 by -10 which when you divide a negative by a negative you would get a positive which leaves you with 21.
