Answer:
Ok so first we subtract 11 on each side so we get a-11=4b-4c then we do-4b on each side to gets a-11-4b=-4c finally divide -4 to each side to get a-11-4b/-4=c
Step-by-step explanation:
Answer:
20
Step-by-step explanation:
The discriminant of a quadratic is the expression inside the radical of the quadratic formula.
b^2-4(ac)
Substitute in the values of a
, b
, and c
.
(-2)^2-4(1*-4)
Elevate the result to find the discriminant.
4+16
=20
Answer:
One hour and 16 minutes
Step-by-step explanation:
12 walls (divided by 12) 1 wall
---- → -----
14 hours (So here we should do the same) 1.16
The equation to represent a possible boundary of the hurricane's eye is (x - 80)² + (y - 26)² = 7.5²

Circle Equation</h3>
The standard equation of a circle is given by:
(x - h)² + (y - k)² = r²
Where (h, k) is the center of the circle and r is the radius.
Given that diameter = 15 miles, hence radius = 15/2 = 7.5. Also, center = (80, 26)
The equation of circle is:
(x - 80)² + (y - 26)² = 7.5²
The equation to represent a possible boundary of the hurricane's eye is (x - 80)² + (y - 26)² = 7.5²
