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
(x + 4)² + (y + 6)² = 16 is in this form
with r² = 16 ⇒ r = = 4
---------------------------------------------------------------
given (h, k) = (5, 2) and r = 20, then
(x - 5)² + (y - 2)² = 400 ← represents the delivery area
Answer:
, 9.9 ounces of water remaining.
Step-by-step explanation:
<u>Given:</u>
Dylan drank 5.2 ounces of water before soccer practice, and 12.9 ounces after practice.
Before he drank any water, there were 28 ounces of water in the container.
<u>Question asked:</u>
Which expression can be used to find the amount of water remaining?
<u>Solution:</u>
Let the amount of water remaining.
Total quantity of water in the container = 28 ounces
Before practice, Dylan drank = 5.2 ounces
After practice, Dylan drank = 12.9 ounces
Remaining amount of water = Total quantity of water in the container - Amount of water is drunk before practice - Amount of water is drunk before practice
Thus, 9.9 ounces of water remaining in the container.
