Answer:

v = (-4, -5)

Step-by-step explanation:

v2 + 9v + 13 = -7

v2 + 9v + 20 = 0

(v + 4)(v + 5) = 0

v = (-4, -5)

Answer:

-4,-5

Step-by-step explanation:

first set the equation equal to 0, v^2+9v+20, factor v^2+4v+5v+20, v(v+4) 5(v+4), so the 2 factors are (v+5) and (v+4), set both equal to that 0. v+5=0 v=-5 and v+4=0 v=-4, so the answer is -4 and -5

If the straight-line distance from her home to the university is 10. 3 km in a direction 25. 0° south of east, what was her aver
DIA [1.3K]

The average velocity in km/h is: 34.3km/hr

<h3>What is average velocity?</h3>

Average velocity refers to speed at which the time intervals (t) change in position or displacement happens, divided by the change in position or displacement (x).

=> Average velocity = \frac{displacement}{time}

Now,

The time taken is missing in the question; the time taken = 18 mins = \frac{18}{60} hours.

The distance of her home to the university = 10.3 km

As, average velocity = \frac{displacement}{time}

=> Velocity = \frac{10.3\times60}{18} = 34.3 km/hr

Hence, the average velocity = 34.3 km/hr
