What is the best estimate of the distance between the point (-25, 10) and the origin? 8 units , 15 units , 23 units or 27 units

  27 units

Step-by-step explanation:

As an estimate, the distance will be somewhere between the maximum magnitude of the two coordinates (25) and the sum of that and about 4/10 of the minimum of the two (25+.4×10 = 29). The only answer choice in that range is 27.

___

The actual distance is found using the Pythagorean theorem (or the distance formula):

  d = √(25² +10²) = √725 ≈ 26.926 ≈ 27 . . . units

all group life insurance is term insurance. actually it is annual renewable term and it is rated on the average age and claims experience of the entire group, which is called "experience rating." remember, this type of insurance has a 31-day grace period and is convertible to whole life upon leaving employment. a contributory group plan requires that both the employer and the employees pay part of the premium. at least 75% of those eligible must participate, so the group is sure to get most of the healthy employees as well as those that are sick.
