Answer:
Step-by-step explanation:
The slope-intercept form is 
, where m is the slope of the line and c is where the line crosses the 
-axis.
To calculate 
we can use the formula 
where 
is the difference in between two points and 
is the difference between 
.
Information we can get from the graph given: 
. Since 
is the point at which the line crosses the -axis.
To find let's get two points from the graph.
Point 1: 
Point 2: 
Now use the equation .
.
Now we have and , let's put them back into the general equation.
If m and n are two positive real numbers whose product is 10, what is the minimum value of m + 2n
2 + 2(4)
Skylar went 13ft per second
Rodrigo went 13 1/2 ft per second
So, 1/2 a ft per second
Step-by-step explanation:
the volume of a cylinder is as for any other regular 3D object :
ground area ×height
the ground area of a cylinder is a circle, so it is
pi×radius² × height
the radius is always half of the diameter (of the diameter is airways twice the radius).
radius = 6/2 = 3 ft.
the volume is then
pi × 3² × 9 = pi × 9 × 9 = pi × 81 ft³
so, the answer is 81pi ft³.
