Answer:
A)
B) There are more species of plants as the number of species of birds that have been sighted in Everglades National Park is 280
Step-by-step explanation:
Total number of species of birds that migrate = 200
We are given that of all the species of birds are sighted in the park
a)Write an equation to find the number of species of birds that have been sighted in Everglades National Park.
Let y be the number of species of birds that have been sighted in Everglades National Park.
We are given that of all the species of birds are sighted in the park
So,
y=280
B)There are 600 species of plants in Everglades National Park. Are there more species of birds or plants in the park?
So, There are more species of plants as the number of species of birds that have been sighted in Everglades National Park is 280
Answer:
(a.a)-(b.b)=|a|²-|b|²=0
As the dot product of the diagonals is 0, the diagonals must be perpendicular.
Step-by-step explanation:
- All the sides are equal in lengths and the sides that are opposite to each other and parallel so it can be expressed as the same vectors.
- These diagonals can be expressed by equation a+b and a-b
- Take the dot product of the diagonals and simplify.
(a+b).(a-b)=(a.a)-(b.b)
4. A vector dotted with itself is its length squared, and we know that the
side lengths are equal to each other.
(a.a)-(b.b)=|a|²-|b|²=0
