Answer:
(x-7)² + (y+1)² = 4² or (x-7)² + (y+1)² =16
Step-by-step explanation:
1) coordinates of the center
x0=(x1+x2)/2=(7+7)/2=7
y0=(y1+y1)/2=(3-5)/2 = -1
(7, -1) - coordinates of the center
2) radius of the circle
length of the diameter =√((x2-x1)²+(y2-y1)²)=√((7-7)²+(-5-3)²)=√(8)²= 8
r = length of the radius = length of the diameter / 2 = 8/2 = 4
3) the equation of the circle
(x-x0)² + (y-y0)²= r²
(x-7)² + (y+1)² = 4²=16
9a+5b you need to distribute the numbers in parenthesis
Answer:
r = 0.05 or 5%
Step-by-step explanation:
3450 = 3000 + (3000 · r · 3)
450 = 9000 · r
450/9000 = r
r = 0.05 or 5%
Answer:
Thus, option “c” 10% is correct.
Step-by-step explanation:
The percentage of students that like dubstep = 30%
The percentage of students that like trance music = 25%
The percentage of student that wants only house music = 20%
The percentage of students that like bot dubstep and trance = 15%
Now we have to find the percentage of students that like trance music but nor dubstep.
The percentage of students that like the trance music but nor dubstep = 100% - 30% – 25 % - 20% - 15%
The percentage of students that like trance music but nor dubstep = 10%
Thus, option “c” 10% is correct.
