Answer:
- circumscribed circle
- The center of a circle circumscribing the triangle connecting the 3 cities will be equidistant from all three cities.
Step-by-step explanation:
The circumscribed circle or <em>circumcircle</em> of a polygon is a circle that passes through all the vertices of the polygon. The center of the circle, the circumcenter, is equidistant from all of the polygon's vertices.
The center is found at the point of intersection between the perpendicular bisectors of any two (non-parallel) chords of the circle. That is, <em>the perpendicular bisectors of any two of the sides of the triangle joining the cities will intersect at the circumcenter</em>.
The method of locating the center of the circle this way is simple and effective.
Answer:
D. 9%
Step-by-step explanation:
1.04 / 2 = 0.52
2.52 / 4 = 0.63 best 1
4.32 / 8 = 0.54
9.12 / 16 = 0.57 best 2
if base on the best deal 1 - 0.63
(0.63 - 0.57) / 0.63 = 0.0952 (≈ 0.09 i.e 9%)
Answer:
0.033 ft
Step-by-step explanation:
Let g = 32.2 ft/s2 and h be the maximum height that water can be filled before the sides shatter.
Pressure is distributed from 0 to maximum at the bottom like the following equation:

So the force generated by water pressure on the side of the tank is

where s = 6ft is the side length of the tank. This force cannot be larger than 200lb



Answer:
50 years
Step-by-step explanation:
use the simple interest formula :
PRT/100
P is the principle (5000)
R is the rate of interest (4)
T is the time taken (x- unknown)
the amount at the end is double the amount invested = 5000*2 = 10000
(5000*4 * x )/100 = 10000
20000x/100=10000
20000x = 100*10000
20000x = 1 000 000
x= 1 000 000/ 20 000
x = 50
it will take<u> 50 years </u>
