Answer:
Step-by-step explanation:
I think the first part of that is asking for the equation for the line of symmetry, although I do not have access to your drop down menu to know for sure! The axis of symmetry is the equation that splits the parabola into 2 parts that are mirror images of each other. In this type of parabola, it will be an "x = " equation. The line that splits the parabola in half is the line x = -2. The function is increasing where the y values are going up. This happens in the interval (-∞, -2].
The function is decreasing where the y values are going down. This happens in the interval [-2, ∞)
The argument is valid by the law of syllogism
Answer:
200.96 units
Step-by-step explanation:
Use the formula for the volume of a cone 
Plug in the values (
=3.14) and multiply them all out
Question 1: The y-intercept is where the line crosses the y-axis. The increments of the y-axis is by 20, and the y-intercept is at (0, 20).
The slope is the change in y over the change in x. Find two points:
(0, 20) and (2, 80)
Now:
(80 - 20)/(2 - 0) = 60/2 = 30
Slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept.
So:
y = 30x + 20
Question 2: Again, look for the y-intercept, which is pretty clear. It's (0, 60).
Now find two points:
(0, 60) and (2, 40)
Find the slope:
(40 - 60)/(2 - 0) = -20/2 = -10
So, the equation is:
y = -10x + 60
And, there you go!
