Answer:
see explanation
Step-by-step explanation:
I will begin with part two, first.
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius.
Given
x² - 18x + y² - 10y = - 6
Using the method of completing the square
add ( half the coefficient of the x/ y terms )² to both sides
x² + 2(- 9)x + 81 + y² + 2(- 5)y + 25 = - 6 + 81 + 25, that is
(x - 9)² + (y - 5)² = 100 ← in standard form
with centre = (9, 5 ) and r = = 10
The answer is B, I believe.
Step-by-step explanation:

- Length ( l ) = 4 cm
- Width ( w ) = 2 cm
- Height ( h ) = 5 cm

Answer:
the answer to your problem is c
Answer:
The anchor is 12 feet far from the point directly below the boat.
Step-by-step explanation:
Given that:
Length of rope connecting the dive boat to an anchor = 13 feet
Depth of water = 5 feet
Here,
The rope connecting the dive boat to the anchor will serve as hypotenuse of a right angle triangle, depth of water will be the height of triangle and distance from anchor to point directly below the boat will be base of triangle.
Using Pythagorean theorem;
a = 5 , c = 13
Taking square root on both sides
Hence,
The anchor is 12 feet far from the point directly below the boat.
