Answer:
(x + 1)² + (y + 5)² = 48
Step-by-step explanation:
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
here (h, k) = (- 1, - 5) and r = 4, so
(x - (- 1))² + (y - (- 5))² = (4 )², that is
(x + 1)² + (y + 5)² = 48 ← equation of circle
Answer:
2 cubic feet
Step-by-step explanation:
Convert all the lengths to feet round them to tenths then multiply them.
The answer you have got should be also correct as you have multiplied all the lengths then converted to cubic feet. Since your instructor has said that this is wrong this seems to be the only option remaining.
1 feet = 12 inches
Answer:
18,432 Km/ h
Step-by-step explanation:
Using the conversions
• 1 Km = 1000 m
• 1 hour = 60 × 60 = 3600 seconds
Then
5120 m = = 5.12 Km and
5.12 Km × 3600 = 18,432 Km / hour
