Answer:
the root of -1 is -1
Step-by-step explanation:
When multiplied by itself, the root is typically a specified number of times gives a specified number or quantity. So -1 × -1 = -1
So there you go
Answer:
first do 58-4 which is 54 then do 54/ 9 which is 6 so the number is 6
<span>The Sears Tower is about 443.2 meters tall.
To convert from feet to meters, simply multiply by 0.3048. So
1454 * 0.3048 = 443.1792 meters.
Since we only have 4 significant figures, the result should also be rounded to 4 significant figures, so we get 443.2 meters.</span>
Answer:
(x+9)^2 + (y+1)^2 = 100
Step-by-step explanation:
Since the question says diameter, we know the boundary in a circle. Therefore, we just need to find the center and radius.
The center is the midpoint of the two endpoints on a diameter.
Here, it is (-9, -1).
Therefore, the left part of the equation is (x- -9)^2 + (y - -1)^2 = (x+9)^2 + (y+1)^2.
The radius: sqrt(8^2 + 6^2) = 10
So the equation is (x+9)^2 + (y+1)^2 = 100
The answer is 14.9 or you can say <span>14 </span><span>9/10.</span>
