Answer:
Geometric sequence
Step-by-step explanation:
Since the accidents increase by 5% this represents that the number is increasing exponentially . So the sequence is geometric sequence. The geometric sequence can be represented by: a, ar, ar^2, ar^3...
Step-by-step explanation:
The volume of a hemisphere is given by :

Taking differentiation,

So,

Put r = 21 m and dr = 0.03 cm = 0.0003 m

Hence, this is the required solution.
Answer:
The x is the x-axis, which is a horizontal line. The y is the y-axis, which is a vertical line. The y-axis goes up or down, while the x-axis goes left or right.
hope this helped.
have a great day!
