Answer:
x^2 + y^2 = 49
Step-by-step explanation:
For center (h,k) and radius r, eqution of the respective circle is
(x-h)^2 + (y-k)^2 = r^2
Answer:
14%
Step-by-step explanation:
The item dropped from $50 to $43 .
Therefore,
Decrease = $50 - $43
= $7
To get the % decrease, divide the decrease by the initial price and multiply the result by 100%
That’s
$7/$50 x 100%
$0.14 x 100%
= 14%
The price of the item decreased by 14%
x + 16 = 64 |subtract 16 from both sides
x = 48
The correct answer would be c. hope this helps
14. The distance between the two points is 14.866.
Distance can be calculated with the following formula:
d=√(x₂-x₁)²+(y₂-y₁)²
d=√(12-2)²+(5-(-6))²
d=√10²+11²
d=√100+121
d=√221
d=14.866
15. The distance between the two points is 20.248.
Use the same formula to find the distance.
d=√(x₂-x₁)²+(y₂-y₁)²
d=√(4-(-3))²+(12-(-7))²
d=√7²+19²
d=√49+361
d=√410
d=20.248
