Given that the line y=c-2x is tangent to the curve y^2=kx where c and k are non-zero constants,express k in terms of c
Viktor [21]

Answer:

k = -8c.

Step-by-step explanation:

y^2 = kx

Find the slope of the tangent by differentiating:

y' 2y = k

y' = k / 2y = the slope of the tangent.

The given equation of the tangent is y = -2x + c so the slope = -2.

Therefore  k/2y =  -2  so k = -4y and y = -k/4

y^2 = kx so k^2/16 = kx giving x = k/16.

Substituting for x and y in y = -2x + c:

-k/4 = -2 k/16 + c

-k/4 = -k/8  + c

c = -k/4 + k/8 = -k/8.

So -k = 8c

k = -8c.

Ratling [72]

Answer:

No

Step-by-step explanation:

A linear equation is an equation of a straight line, which means that the degree of a linear equation must be

0 or 1 for each of its variables. In this case, the degree of variable y is 1

and the degree of variable x is 2.

Not Linear

. a. answers vary b. Yes; the taller the person is, the longer his or her reach. c. The independent quantities were represented by the x-axis, while the dependent _quantities were represented using the y-axis. d. A trend line can generalize the trend in the data. 1-18. a. The graph is in the first quadrant because negative lengths do not exist; the range of the data determines the kind of graph. b. Counting by 10’s makes the graph a reasonable size. c. In this situation, including the origin with the graph is not suggested. It is easier to see the trend line when the data are not bunched together, and this can be done by changing the range of the graph to exclude the origin. d. The graph should include the maximum height (that of Yao Ming) on the x-axis and the height of the tunnel on the y-axis. 1-21. a. b. c. d. e. f. g. h. 1-22. a. –8 b. 29 c
