Solve for k:
X^2 + (y - k)^2 = 21
Subtract X^2 from both sides:
(y - k)^2 = 21 - X^2
Take the square root of both sides:
y - k = sqrt(21 - X^2) or y - k = -sqrt(21 - X^2)
Subtract y from both sides:
-k = sqrt(21 - X^2) - y or y - k = -sqrt(21 - X^2)
Multiply both sides by -1:
k = y - sqrt(21 - X^2) or y - k = -sqrt(21 - X^2)
Subtract y from both sides:
k = y - sqrt(21 - X^2) or -k = -sqrt(21 - X^2) - y
Multiply both sides by -1:
Answer: k = y - sqrt(21 - X^2) or k = sqrt(21 - X^2) + y
Answer:
The answer is -48
Step-by-step explanation:
First step is to follow PEMDAS
So we start solving whatever is in the ( )
4^2 is in the ( ) 4^2 = 16 then we multiply
-3 * 16 which is -48

The velocity of the jogger will be 0.18 miles per minute.
<h3>What is velocity?</h3>
Velocity is defined as the ratio of the distance moved by the object in a particular time. The velocity is a vector quantity so it needs both the magnitude and the direction.
Given that:-
- It took the jogger 45 minutes to cover the 8 miles
The velocity will be calculated as:-
V = Distance ÷ Time
V = 8 ÷ 45
V = 0.18 miles per minute
Therefore the velocity of the jogger will be 0.18 miles per minute.

Answer:
4,450
Step-by-step explanation:
You muiltiply 250 times 15 then you add 700
600×3.5%=21. As a result, there are 21 phones that likely to be defective. Hope it help!
