Answer:
48%
Step-by-step explanation:
96 out of the 200 species of birds have been seen nesting. To make it easier, let's make it out of a hundred. Just divide both numbers by 2, this will result in the ratio being 48 out of 100. Now, we have our percentage, 48%.
Y= mx +b slope intercept form.
b= 60, now do rise over run to find m
4/4= 1, m=1
Final equation: y=1x+60
Answer:Length and angle measure
Step-by-step explanation:
The length measure is the distance along the curve (arc) and the angle measure is the angle that the arc makes with the center of the circle.

The vertex of the given parabola is the point (3, 25).
<h3>
How to get the vertex of the parabola?</h3>
If the parabola has roots x₁ and x₂, then the vertex of the parabola is at:
xₙ = (x₁ + x₂)/2
Here the parabola is:
y = (-2 - x)*(x - 8)
We can rewrite that to:
y = -(x + 2)*(x - 8)
Then the two roots are:
x = -2 and x = 8
Then the vertex is at:
xₙ = (8 - 2)/2 = 6/2 = 3
To get the y-value of the vertex, we evaluate the equation in x = 3:
y = -(3+ 2)*(3 - 8) = -5*(-5) = 25
The vertex is (3, 25).
