What is the average rate of change of f(x) from 3 to 6?

It's 13.

Step-by-step explanation:

Average rate = [f(6) - f(3) ] / (6-3)

= [ (6^2 + 3(6) + 2 - (3^2 + 3(2) + 2) ] / 3

=  (56 - 17)/ 3

= 39 / 3

= 13 .

7.9m and 4.3°

step-by-step explanation:

let east be +x and north be +y, x = distance * cos θ, y = distance * sin θ  

for 3.5 south, y = -3.5  

for 8.2, x = 8.2 * cos 30 and y = 8.2 * sin 30  

for 15 west, x = -15  

total x = 8.2 * cos 30 – 15 ≈ -7.9  

total y = -3.5 + 8.2 * sin 30 = 0.6  

magnitude = [(8.2 * cos 30 – 15)^2 + 0.6^2)]^0.5  

the magnitude is approximately 7.9 m  

tan θ = y/x = 0.6/-7.9  

the angle is approximately 4.3˚ north of west
