Focus of a parabola:
where vertex (h,k) p is the distance from vertex to focus
<h3><u>Radius as function of volume is:</u></h3>
<em><u>Solution:</u></em>
<em><u>The volume of cone is given as</u></em>:
Where,
r is the radius
h is the height
From given,
height = 20 inches
From formula,
Rearrange , so that r is alone in left side of equation
Substitute h = 20
Thus, radius as function of volume is:
9514 1404 393
Answer:
k = 7
m = 8
Step-by-step explanation:
The diagonals bisect each other, so each half is equal to the opposite half.
k +4 = 11 . . . . down-sloping diagonal
k = 7
__
m = 8 . . . . up-sloping diagonal
Answer:
Part a)
Part b)
Step-by-step explanation:
Part a) Set up a proportion to show the relationship between the distance in miles and the size of the map
we know that
The scale on a map is equal to
That means
1 inch on a map represent a 15 miles in real life
Part b) How far apart are the cities in real life?
Let
x -----> the distance in real life
using proportion
