All real numbers
Step-by-step explanation:
The domain is where the graph touches all of the x-coordinates. This parabola touches all x-coordinates from -infinity to +infinity (all real numbers) because it continues outward forever.
Answer:
9.8 degree + 80.2 degree
As both need to add up to 90 degree to be complementary.
Step-by-step explanation:
Complementary angle means adds up to 90 degree.
Therefore- 90-80.2 = 9.8 degree
Answer:
( x + 3)² + ( y + 7)² = 361
Step-by-step explanation:
The equation of a circle written in standard form is ( x – h)² + ( y - k)² = r². The center is (h, k) and the radius is r.
With the given information of center (-3, -7) and radius 19, we get
[ x – (-3)]² + [ y - (-3)]² = (19)²
( x + 3)² + ( y + 7)² = 361
