Answer:
(x+1)²+(y-2)²= 20
Step-by-step explanation:
P = (-3,-2)
Q = (1, 6)
<u>Center (h, k)</u>
C = ((-3+1)/2 , (-2+6)/2)
C = (-2/2 , 4/2)
C = (-1 , 2)
Radius = Distance from the center to point Q
R = √((1-(-1))² + (6-(2))²)
R = √((2)² + (4)²)
R = √(4+ 16)
R = √20
Equation
(x-h)²+(y-k)²= R²
(x-(-1))²+(y-2)²= (√20)²
(x+1)²+(y-2)²= 20
Answer: 250 students
Step-by-step explanation:
since we know that 24% purchased their lunch, we know 76% brought their lunch from home. It is given that 190 students brought their lunch from home so we can create the proportion
then we use cross multiplication to solve for x and we get 250 students.
