Answer:
A
Step-by-step explanation:
Time Distance
0 0
2 2*25 = 50
4 4*25 = 100
6 6*25= 150
8 8 * 25 = 200
Since 1 foot is equal to 12 inches, 12 inches x 2 feet = 24 inches
2 feet = 24 inches
30 inches is longer
Answer:
C(5,-9) and r=8.
Step-by-step explanation:
C(p, q) - center
r=radius
k:x^2 +y^2 +dx+ey+f=0
x^2+y^2 - 10x+18y+42=0
d=-10, e=18, f=42
p=-d/2=-(-10)/2=10/2=5
q=-e/2=-18/2=-9
r^2 =p^2+q^2-f
r^2 =5^2 +(-9)^2 - 42
r^2=25+81-42
r^2 =106-42
r^2 =64
r=sqrt(64)
r=8
C(p,q)=C(5,-9) r=8
