Answer:
-5,12 because its to the right obviously you rflect it to the left because its y axis and boom -5,12
Step-by-step explanation:
Lets calculate the taxes that would been payed at each city:
city1 = 12000(7%) = 12000(0.07) = 840
city2 = <span>12000(8.5%) = 12000(0.085) = 1020
So if you go to city1 instead of city2, you save 1020 - 840 = 180
So you would save $180 from $12000, that is:
180 out of 12000
= 180/12000
= 0.015
and that is the 1.5%, that is what you could save</span>
The top one too. It is perfect.
Answer:
Midpoint =1.5,1
radius 4.71699
C = 29.623
A =69.865
Step-by-step explanation:
To find the midpoint, add the endpoint coordinates together and divide by 2
M = (x1+x2)/2, (y1+y2)/2
= (-1+4)/2, (5+-3)/2
= 3/2 , 2/2
=1.5,1
Once we know the midpoint, we can find the radius from one endpoint to the midpoint
d = sqrt( (x2-x1)^2+ (y2-y1)^2)
sqrt( (1.5--1)^2+ (1-5)^2)
sqrt(( 1.5+1)^2 + (4)^2)
sqrt( 2.5^2 +16)
sqrt(6.25 +16)
sqrt(22.25)
4.71699
The circumference is given by
C = 2*pi*r
= 2* (3.14) * 4.717
= 29.623
The area of a circle is given by
A = pi r^2
= 3.14 * 4.717^2
=69.865
