In a quadratic equation , we use the quadratic formula to find the solutions x = (-b ± √(b2 - 4ac)) / 2a where a, b, and c are coefficients of the equation ax2 + bx + c = 0 Since x=6 is the only x-intercept, the equation would be (x - 6)(x - 6) = 0 Expanding this out, we get x2 - 12x + 36 = 0 In this equation, a = 1b = -12c = 36 Now the discriminant is the square-root part of the formula: b2 - 4ac Now plug in the values of a,b, and c into the discriminant. (-12)2 - 4(1)(36) = 144 - 144 = 0 This number is under the square-root. The square-root of 0 is 0. Your answer is (A).
(I had the same question in math last week)
The rate is 0.30 km/min. The rate in linear functions, which must be assumed with only two given points can be traced to calculating the slope (m) of the line or rate.
m= (y2-y1) / (x2-x1)
with our two given points (x,y) we fill out the equation as:
M= (12 - 0) / (40 - 0) or M = 12/40 = 0.3
keeping our units intact 12 km / 40 min so the answer is 0.3 km/min
<span>This intersection produces a line. However, if the angle of the plane is less than the cone's angle, then the intersection produces a point. If the angle of the plane is greater than the angle of the cone, then the intersection is two lines intersecting at the vertex. If the plane intersects at some point other than the vertex, then the intersection is a circle if the plane is perpendicular to the cone's axis. It is an ellipse when the plane's angle is less than the cone's angle. It's a parabola when the planes's angle equals the cone's angle.</span>

Answer:
11,550
Step-by-step explanation:
1200- 675( because its descending) + 250 ( its ascending) - 525 = 11,550
