The radius, r, of the circle is the distance from the center to any point on the circle.
r = √[(1-(-3))2+(5-2)2] = √25 = 5
An equation of the circle with center (h,k) and radius r is:
(x-h)2 + (y-k)2 = r2
So, in this problem, we have (x+3)2+(y-2)2=25.
To find a point on the circle with x-coordinate -7, replace x by -7 in the equation of the circle and solve for y:
(-7+3)2+(y-2)2 = 25
16 + (y-2)2=25
(y-2)2 = 9
y-2 = 3 or -3
So, y = 5 or -1
The points (-7,5) and (-7,-1) both lie on the circle.
Answer:
ta check the largest number to be x + 10 then the other number to be x then he quit x + 10 + x is equals to 52 collect the like terms x + x + 10 is equals to 52 2x + 10 is equals to 52 move channel to the equals sign so that it becomes 2 x is equals to 52 - 10 2 x is equals to 42 divide both sides by 2 x is equals to 21 so the largest number that was x + 10 now is 31 and the other number is 21
It is more than 100 yards. Take the equation a^2+b^2=c^2. plug in a(100) and b(53 1/3) and find the squares of those. then add them up. that should equal 12840.89. then find the square root of that which is 113.32 (rounded). so it is more than 100 yards.
