The discriminante :
b^2-4ac

1^2 - 4 * -2 * -28 = 1 - 224 = -223

When the discriminant (b^2-4ac) is less than 0, the equation had no real solutions.

-223<0, so, 2x^2+x-28 = 0 has no real solutions.


Hope that helps :)

A jacket cost £70 but is reduced by 12% in a sale. What is its new price

How do you write an exact angle measure without approximating to a decimal value?
dimulka [17.4K]

an exact angle measure without approximating to a decimal value is given below.

Step-by-step explanation:

Since an angle of 2 has degree measure 360° it follows that an angle of 1 radian has degree measure (180/ )°. Likewise, an angle of size 1° has radian measure /180. We now can easily obtain a formula to convert from degrees to radians and vice-versa. To convert from degrees to radians, multiply the angle by /180.

convert decimal degrees to DMS :

  • For the degrees use the whole number part of the decimal.
  • For the minutes multiply the remaining decimal by 60. Use the whole number part of the answer as minutes.
  • For the seconds multiply the new remaining decimal by 60.
