Answer: (- 15, 20)
Step-by-step explanation:
In the format (x – h)² + (y – k) = r², the center of the circle is at point (h, k).
-> The negatives in the first equation, bolded and underlined, means we change the sign of positive to negative or negative to positive.
(x <u>-</u> h)² + (y <u>-</u> k) = r²
(x + 15)² + (y - 20)² = 100
(x <u>-</u> 15)² + (y <u>+</u> 20)² = 100
(x <u>- 15</u>)² + (y + <u>20</u>)² = 100
(- 15, 20)
We can also see this with graphing. See attached.
The center of the circle will be at point (- 15, 20).

The Fahrenheit scale is now usually defined by two fixed points: the temperature at which pure water freezes into ice is defined as 32 °F and the boiling point of water is defined to be 212 °F, both at sea level and under standard atmospheric pressure (a 180 °F separation).
Answer:
Density of steel = 80.73 gm/
Step-by-step explanation:
The figure is made up of cuboid and square pyramid.
Height of cuboid, h = 9 cm
Length of cuboid, l = 6 cm
Width of cuboid, w = 6 cm
Volume of cuboid is given by the formula:
Density of Wood , 
= 0.68g/
We know that formula of Density is:
Putting the values:
Total weight = 
970 = 220.32 
= 749.68 gm
Volume of pyramid is given as:
Base is a square with side 6 cm
Density of Steel/Pyramid:
It is 90 yds squares because formula for a triangle for area is (length times width) divided by 2. So it would be 180 divided be 2 which is 90 :)
The answer will be 190.76 square inches. Hope it help!
