Center of the circle: C=(3,8)=(h,k)→h=3, k=8
Radius of the circle: r=5
Standard form of the equation for the circle:
(x-h)^2+(y-k)^2=r^2
(x-3)^2+(y-8)^2=5^2
(x-3)^2+(y-8)^2=25
General for of the equation for the circle:
(x)^2-2(x)(3)+(3)^2+(y)^2-2(y)(8)+(8)^2=25
x^2-6x+9+y^2-16y+64=25
x^2+y^2-6x-16y+73=25
x^2+y^2-6x-16y+73-25=25-25
x^2+y^2-6x-16y+48=0
Answer: The general form of the equation for the circle is:
x^2+y^2-6x-16y+48=0
Answer:
0.454...
Step-by-step explanation:
58 to x should be the ratio of 6/3 or 1/2 if they are similar.
Find out how much bigger 58 is compared to 6, the matching side on the other polygon.
58/6 = ~9.7
The x side should be half of this, just like it is on the smaller polygon.
9.7/2 = 4.85
4.85 x 3 = 14.55

<u>Problems given:</u>
- - 2000 + 20.5 = - 1979.5 ≈ -1980.0 ⇒ 3 significant figures
- - 106.2 + 54.07 = - 52.13 ≈ -52.1 ⇒ 3 significant figures
Zeros at the end are not counted as significant figures
