Answer:
A = 97.968 cm^2 = 98.0 cm^2
Step-by-step explanation:
A = (78/360)*3.14*12^2
A = (78/360) * 3.14 * 144
A = (78/360) * 452.16
Answer:
y=x+3
(0,3)(1,4)
y=x+2
(0,2)(1,3)
Step-by-step explanation:
- For Y=X+3 it could be any point for Y as long as X is 3 less than Y.
- For Y=X+3 it could be any point for X and long as Y is 3 more than X.
- For Y=X+2 it could be any point for Y as long as X is 2 less than Y.
- For Y=X+2 it could be any point for X and long as Y is 2 more than X.
Answer:
The graph of the system in the attached figure
Step-by-step explanation:
we have
isolate the variable y
----> equation A
This is the equation of a vertical parabola open down (because the leading coefficient is negative)
The vertex represent a maximum
the vertex is the point (0,2)
---> equation B
This is the equation of a circle centered at (0,0) with radius 3 units
The solution of the system of equations is the intersection points both graphs
using a graphing tool
The solutions are the points (-2.05,-2.19) and (2.05,-2.19)
see the attached figure
5/8 * 125/125 = 625/1,000 = 0.625
62.5 percent
Solution: 62.5%
