Answer:
The most common methods are wind, water, animals, explosion and fire. Dandelion seeds float away in the wind.
Step-by-step explanation:
Because plants cannot walk around and take their seeds to other places, they have developed other methods to disperse (move) their seeds.
The average rate of change of the function over the given interval is 9
Here, we want to calculate the average rate of change of the function within the given interval
Mathematically, given a function f(x) , the average rate of change of the function within the interval a ≤ x ≤ b is given below;
withe respect to this question;
a = 1
b = 4
f(a) = f(1) = 12
f(b) = f(4) = 39
The average rate of change within the given interval is thus;
A they are at 90° angles and that is the definition of being perpendicular.
Let a ∈ A. Then a is some integer that is divisible by 4, so we can write a = 4k for some integer k.
We can simultaneously rewrite a as a = 2•2k, so 2 clearly divides a, which means a ∈ B as well.
Therefore A ⊆ B.
