One x-intercept for a parabola is at the point

Mathematics
1 answer:
ra1l [238]3 years ago
3 0

Answer:

x=-1 or (-1,0)

Step-by-step explanation:

(-4 +- sqrt(4^2-4(5)(-1)))/2*5

(-4 +- sqrt(16+20))/10

(-4 +- sqrt(36))/10

(-4 +- 6)/10

x= (-4+6)/10 = 2/10 = 1/5 = 0.2

x= (-4-6)/10 = -10/10 = -1

x-intercepts: (0.2,0), (-1,0)

How would you convert an angle in degrees to an angle in radians?
Scilla [17]
For reference, one full circle is 360 degrees or 2pi radians.

If we were to convert 360 degrees to radians, we could set up the following equation:

360k = 2pi

where k is a constant. By solving for k, we can find what value we must multiply any angle in degrees by to get its radian counterpart.

Divide both sides by 360:

k = 2pi/360

Reduce:

k = pi/180

So to convert an angle from degrees to radians, multiply it by pi/180. For example, 120 degrees would be:

120 * pi/180 = 2pi/3 radians
