Answer:
Car 1 slope = 35
Car 2 slope = 40
Red line(car 2) is steeper than the blue line(car 1)
slope is miles per gallon
Step-by-step explanation:
Slope formula is
To find slope, pick two points from graph of Car 1
(4,140) (6,210)
= 35
To find slope, pick two points from graph of Car 2
(3,120) (5,200)
= 40
When slope is larger then line is steeper
slope of Car 2 is greater than slope of Car1
So Red line is steeper than the blue line.
Slope is change is y over change in x
It means Change in miles over change in gallons
So slope is miles per gallon
Area of a circle is directly proportional to the square of radius of the circle while the circumference is proportional to the radius of the circle. This means that if the radius of a circle is increased x times, then its area will be increased to x^2 times the original area, and the circumference will increase to x times the original circumference.
Thus when the radius is doubled, or in other words if radius mad 2 time the original radius, the area of circle will become 2^2 = 4 time the original area. The circumference will become 2 times the original circumference.
We can calculate exact area and circumference of a circle from its radius using the following equations:
Area of circle = (pi/4)*r^2
Circumference of circle = 2*pi*r
Where r is the radius of the circle.
I know this is a lot, sorry.
Answer:
D
Step-by-step explanation:
1. The domain is all x values for the function.
2. Since the line starts at the x value of 3, it is included and since it goes to the right, it also includes all the values greater than 3.
3. Therefore, x>_3
