Ronjeev is paddling a kayak across a river. he wants to paddle the kayak straight across the river from east to west at a velocity of 12 kilometers per hour. however, there is a current flowing south that is pushing his kayak downstream at a velocity of 5 kilometers per hour. what is the actual velocity, in kilometers per hour, of the kayak? a 7 b 12 c 13 d 17

Option C is the correct answer.

Step-by-step explanation:

Refer the figure.

We need to find resultant of two perpendicular vectors, that is the actual velocity.

Velocity of Ronjeev = 12 kilometers per hour

Velocity of River = 5 kilometers per hour

Option C is the correct answer.

you need to show us the graph.

step-by-step explanation:

-7

step-by-step explanation:

x^2 + 18x + 74 = (x + 9)^2 - 81 + 74

= (x + 9)^2 - 7.

so q = -7.
