Given matrix D below, which matrix represents -5D?
Answers
-5D means multiply all the elements of D by -5
i.e. -5 * -10 = 50
-5 * 10 = -50
-5 * -5 = 25
-5 * 15 = -75

Final answer:
To represent the elevation range for each type of plant life, write a compound inequality for each type using the minimum and maximum elevations.
Explanation:
To write a compound inequality to represent the elevation range for each type of plant life, we need to consider the minimum and maximum elevations for each type. Let's say Type A has a minimum elevation of 1000 ft and a maximum elevation of 3000 ft, and Type B has a minimum elevation of 2000 ft and a maximum elevation of 4000 ft. We can represent the elevation range for Type A as: 1000 ≤ x ≤ 3000, and for Type B as: 2000 ≤ x ≤ 4000.

or
x^3-8 = (x-2)(x^2+4x+4)
x³ = 0 + 8
x³ = 8
Take the cube root of both sides
∛x³ = ∛8
∛(x*x*x) = ∛(2*2*2)
x = 2

Answer:
The constant is 40
Step-by-step explanation:
According to the question we are given an equation that represents the given situation as d = 40t where;
d is the distance in km
t is the time in seconds.
The given function is a direct proportionality. For example if p is directly proportional to q, this is expressed as p ∝ q where ∝ is the proportionality sign. In order to remove the sign we will introduce a constant say "k". The equation will become;
p = kq (p and q are the variables)
A direct proportionality means that as a variable is increasing, the other is increasing and vice versa. Comparing p = kq with d = 40t, we can see that k is equal to 40 and d is directly proportional to t
Hence the constants of proportionality for the relationship between distance in kilometers and number of hours is 40 on comparing.
