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
Answer:
9043.2 in^3 of lead
Step-by-step explanation:
the formula is (4/3)(3.14)r^3
so,
(4/3)(3.14)(3^3) * 80
9043.2
3(n-8)=2n-2
3n-24=2n-2
Subtract 2n from both sides to get
n-24=-2
Adding 24 to both sides gives you
n=22. The number therefore is 22. Hope this helps!!!
Answer:
6
Step-by-step explanation:
4 / 2/3
Think of it like this.
4 / 2/3 (if this were in fraction form)
4 * 3/2 (Reciprocal)
12/2
