the points j(-8,9) and k(-2,-5) are endpoints of a diameter of circle C. What equation would represent circle C
Answers
The equation of circle C will be;
⇒ (x + 5)² + (y - 2)² = 7.61²
What is Circle?
The circle is a closed two dimensional figure , in which the set of all points is equidistance from the center.
Given that;
The points j(-8,9) and k(-2,-5) are endpoints of a diameter of circle C.
Now,
Since, The points j(-8,9) and k(-2,-5) are endpoints of a diameter of circle C.
Hence, The diameter of circle = √(- 2 - (-8))² + (- 5 - 9)²
= √ 6² + 14²
= √36 + 196
= √232
= 15.23
Thus, The radius of circle = 15.23 / 2
= 7.61
And, The center of the circle = (- 8 + (-2)) / 2 , (9 + (-5))/2
= (- 5, 2)
So, The equation circle C is,
⇒ (x - (-5))² + (y - 2)² = 7.61²
⇒ (x + 5)² + (y - 2)² = 7.61²

Answer: The width of the field = 160 feet
Step-by-step explanation:
We are given that , A field is yards wide.
That means , The width of the field = yards
Since , the fraction is in mixed for , so first we convert this into improper fraction.
Therefore , the width of the field = yards
Since 1 yard = 3 feet.
⇒ the width of the field = feet
Therefore , the width of the field = 160 feet

Answer:
Thor is the best deal.
Step-by-step explanation:
Thor is $10.35, Lemon is $11.73, Patrick is $14.66, and Sarah is $16.63.
For Thor, multiply $1.15(2)=$2.30. Then multiply $1.15(7)=$8.05. Add these together to get $10.35.
For Lemon, multiply 17($1.15)=$19.55. Then subtract by $7.82 to get $11.73.
For Patrick, use the equation we already did 17($1.15) and subtract $4.89 from it to get $14.66.
Last, For Sarah multiply our $19.55 (.15) to find 15% and get 2.934. Then subtract $19.56 - 2.934 to get $16.626. Round to $16.63.
Hope this helped!
