Answer:
A)![\frac{4}{7} y = 200](https://tex.z-dn.net/?f=%5Cfrac%7B4%7D%7B7%7D%20y%20%3D%20200)
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, ![\frac{4}{7} y = 200](https://tex.z-dn.net/?f=%5Cfrac%7B4%7D%7B7%7D%20y%20%3D%20200)
![y = \frac{200 \times 7}{4}](https://tex.z-dn.net/?f=y%20%3D%20%5Cfrac%7B200%20%5Ctimes%207%7D%7B4%7D)
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:
sin(arccos(-4/√25)) = 0.6
Step-by-step explanation:
The expression you want to evaluate is
sin(arccos(-4/√25))
= sin(arccos(-4/5))
We place this expression into a calculator and get the result
arccos(-4/5) = 2.498 rads = 143.1°
then
sin(143.1°) = 3/5
sin(143.1°) = 0.6
sin(arccos(-4/√25)) = 0.6
