Olivia needs $36 to buy a coat. she has saved $8 and plans to work as a babysitter to earn $7 per hour. which inequality shows the minimum number of hours, n, that olivia should work as a babysitter to earn enough to buy the coat? (5 points) 7n ≥ 36 + 8, so n ≥ 6.3 8 + 7n ≤ 36, so n ≤ 4 7n ≤ 36 + 8, so n ≤ 6.3 8 + 7n ≥ 36, so n ≥ 4

Sketch the vector field vector f( vector r ) = 8vector r in the xy-plane. select all that apply. the length of each vector is 8. the lengths of the vectors decrease as you move away from the origin. all the vectors point away from the origin. all the vectors point in the same direction. all the vectors point towards the origin. the lengths of the vectors increase as you move away from the origin.
