Perpendicular lines, slope is opposite and reciprocal. so if the slope of line c is -4 then the slope of line d will be 1/4
Hope it helps

The equation of a circle in standard form is
+=
where (a , b) are the coordinates of the centre and r is the radius
The centre is at the midpoint of the endpoints and the radius is the distance from the centre to either of the 2 endpoints
Using the midpoint formula
midpoint = [(x+, (+
where (,=(3,8) and (,=(-7,2)
centre = ((3-7),(8+2)) = (-2,5)
Calculate r using the distance formula
r = √(-)²+(-)²)
= √((3+2)²+(8-5)²) = √(25+9) = √34 ⇒ r² =(√34)² = 34
equation of circle is : (x+2)²+(y-5)² = 34
Answer:
A- 462.86
Step-by-step explanation:
Final result is 3.
Quotient = (60 + 30) / 10
= 90/10
= 9.
Difference of quotient and 3
= 9 - 3
= 6
6 / 2 = 3.
