Vector u has a magnitude of 5 units, and vector v has a magnitude of 4 units. which of these values are possible for the magnitude of u + v? select all correct answers.1 unit9 units11 units13 units

Step-by-step

The maximum and minimum values are the positive sum and difference of the two magnitudes.  The magnitude of u+v can range between these two limits, namely 5+4=9, and 5-4=1.

Therefore among the given choices, the possible values of u+v are 1 unit and 9 units.  11 and 13 are greater than the maximum so do not apply.

15% chance.

step-by-step explanation:

3/10 times, the 5 year old will get a tablet. 5/10 times, the 13 yer old will get a tablet. multiply both fractions to get 15/100 times, both would have a tablet.
