Equation for a circle with center (0, −4) and radius 8 is x²+y²+8y-48 = 0</h2>
Step-by-step explanation:
Equation of circle with (h,k) as center and radius r is given by,
(x-h)²+(y-k)² = r²
Here we need to find equation for a circle with center (0, −4) and radius 8.
Center = (h,k) = (0, −4)
Radius = r = 8
Substituting in equation
(x-h)²+(y-k)² = r²
(x-0)²+(y-(-4))² = 8²
x²+(y+4)² = 64
x²+y²+8y+16 = 64
x²+y²+8y-48 = 0
Equation for a circle with center (0, −4) and radius 8 is x²+y²+8y-48 = 0
Answer: It would be 30.5 i hope this helps.
Answer:
8.3%
Step-by-step explanation:
A worker is paid from noon to 3 pm. So the worker works for 3 hours.
To find the percentage, we need to have the same units.
To do this, convert 3 hours to minutes and get 180 minutes.
We can now write a fraction (break minutes/total work time) to find the percent of the number of minutes in their break as a part of their whole paid shift.
This fraction is 15/180.
We can now simplify this fraction to 1/12.
Then convert into decimal form and get 0.0833.
Finally convert this decimal into a percentage by multiplying by 100 and get 8.3%
