A15-m2 wooded area has the following: 30 ferns, 150 grass plants, and 6 oak trees. what is the population density per m2 of each of the above species?

How to solve: divide the number of specimen over the total area they take over. Then, divide both denominator and numerator by the total area.

1. Ferns: 30 ferns/15 m² --> divide by 15 to both --> 2 ferns/m²

2. Grass plants: 150 grass/15 m² --> divide by 15 to both --> 10 grass/m²

3. Oak trees: 6 tree/15 m² --> divide by 15 to both --> 0.4 tree/m²

hello :

70y^8 + 30y^6 = 2 ( 35 y^8 + 15y^6)

the lenght is : 35 y^8

the width is : 15y^6

for this pair of functions g(x)=x-2 and f(x)=|x| is (g o f)(a)= |a| -2

step-by-step explanation:

g(x)=x-2

f(x)=|x|

(g o f)(a)=?

(g o f)(x)=g(f(x))

(g o f)(x)=g(|x|)

(g o f)(x)=|x|-2

(g o f)(a)=|a|-2
