1) What is the product of the two polynomials? 15.
A) -3x2 - 22x - 24
B) 3x2 – 22x - 24
-3x2 - 14x - 24
D) -3x2 - 22x + 2

2) Subtract x+6 from -3x-4

a) -4x-10
b) 4x+10
c) -2x+2
d) -x+10

yes. we do proportions in probabilities.

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
