Answer:
It's 50 percent right
Step-by-step explanation:
there are many colors and they could all be different
we have
using a graph tool
see the attached figure
<u>The vertex of the quadratic equation is the point </u>
That means that the maximum height of an arch is equal to
<u>The zeroes of the function are the points </u>
That means that the width of the arch at its base is equal to difference between the zeroes
therefore
<u>the answer is </u>
The width of the arch at its base is equal to the difference between the zeroes
The volume of a cone by definition is given by:
V = (pi * r ^ 2 * h) / (3)
Where,
r: radio
h: height
Clearing the height of the original cone we have:
h = (3 * V) / (pi * r ^ 2)
Substituting values:
h = (3 * 1875) / (pi * (40) ^ 2)
h = 1.119058194
We now look for the scale factor:
K = 16/40
Simplifying:
K = 4/10
K = 2/5
We apply the scale factor to the new volume:
V '= ((k ^ 3) * (pi * r ^ 2 * h)) / (3)
Substituting:
V '= (((2/5) ^ 3) * (pi * (16) ^ 2 * (1.119058194))) / (3)
V '= 19.2 cm ^ 3
Answer:
the volume of a similar cone with a radius of 16 cm is:
V '= 19.2 cm ^ 3
Answer:
12.5 pages
Step-by-step explanation:
32/2= 16 min per page
200/16= 12.5 pages
or
200/x = 32/2
200/32= 6.25
6.25*2= 12.5
Answer:
-3, -3/2, 0, 5, 11
Step-by-step explanation:
-3/2 = -1.5
-3, -3/2, 0, 5, 11
