Answer:

275 but that only depends what you are estimating  to if you are estimating to whole numbers then it is 275

Step-by-step explanation:

186.231 the two is lower then four so the eight stays the same

88.941 the nine is above five so it makes the eight go to nine

four and below stay the same and five and above give it a shove

186+89=275

Vector u has a magnitude of 4 with a direction of 50°. Vector v has a magnitude of 6 with
Luda [366]

Answer: <8.01, 5.60>.

Step-by-step explanation:

Vector:

v= (r\cos\theta,r\sin\theta)

, where r = magnitude and \theta = angle .

As per given,

u=(4\cos 50^{\circ}, 4\sin 50^{\circ})\\\\\approx(4(0.64),4(0.77))\\\\=(2.56, 3.08)

v=(6\cos 25^{\circ}, 6\sin 25^{\circ})\\\\\approx(6(0.91),6(0.42))\\\\=(5.46, 2.52)

Consider

u+v=(2.56,3.08)+(5.46,2.52)\\\\=(2.56+5.46,3.08+2.52)\\\\=(8.02,\ 5.60)

Hence, the correct option is <8.01, 5.60>.
