A plane intersects one cone of a double-napped cone such that the plane is parallel to the generating line.

1 answer:

6 0

The conic section that would be best formed on the way the double-napped cone gets cut would be a parabola. By definition, a parabola is a conic section in which it is mostly characterised of having a U-shape wherein it is symmetrical and an open plane curve.

If the points (–2, –1), (–1, 0), (2, 3), and (–3, –2) are joined to form a straight line, at what point does the line intersect

Snowcat [4.5K]

Answer:

Step-by-step explanation:

Pick 2 points and use the slope formula

(–1, 0), (2, 3)

Slope =(y2−y1)/(x2−x1)

(3−0)(2−−1)

3/3

y=1x

Angie read 22 pages during a 30-minute study hall. At this rate, how many pages would she read in 45 minutes

frosja888 [35]

45 minutes is equal to 1.5 times 30:

1.5*30=45

so she will also read 22*1.5 pages, which is 22+11=33

so she will read 33 pages

a student found the slope of a line that passes through the points (1,14) and (3,4) to be 5. what mistake did she make?

SSSSS [86.1K]

M = (y2-y1)/(x2-x1)
= (4-14)/3-1
= -10/2
= -5
