20, 100
Step-by-step explanation:
You look at the tens column, in this case the numbers would be "7" in the "671" and the "3" in the "32". If you're rounding the tens column you look at the ones column and if the number is bellow 5 you round down, if its 5 nd over you round up. Since the number is 1 in the ones column that means the 7 will round down so it would be "670", for "32" the number is "2" (which is bellow 5) so we will round down again to "30". This will leave you with the equation 670×30 which is 20, 100.
Calculate it up and it shall be the anwser
Answer:
(x + 3)^2 + (y - 5)^2 = 17
Step-by-step explanation:
To find the radius: distance from point (-2,1) to the center from point (-3,5).
d = sqrt [(-2 - -3)^2 + (1 -5)^2]
d = sqrt [(-2 + 3)^2 + (1 -5)^2]
d = sqrt (1)^2 + (-4)^2 = sqrt 17
Radius = sqrt 17
Equation of the circle:
(x - h)^2 + (y - k)^2 = r^2
h = 3, k = 5, r = sqrt 17
(x - -3)^2 + (y - 5)^2 = (sqrt 17)^2
(x + 3)^2 + (y - 5)^2 = 17
A square root is Is a number times it's self. Like 2 is the square root of 4, because 2*2=4. 3 is the square root of 9, because 3*3=9....... And 7 is the square root of 49, because 7*7=49.
Try 55, hope this helped.. If not I’ll come back
