Test the set of polynomials for linear independence. if it is linearly dependent, express one of the polynomials as a linear combination of the others. (if the set is linearly independent, enter independent. if the set is linearly dependent, enter your answer as an equation using the variables f, g, and h as they relate to the question.) {f(x) = x, g(x) = 2x − x2, h(x) = 2x + 3x2} in

step-by-step explanation:

18.75 gallons

step-by-step explanation:

i think it will be zero as slope has a formula of difference between initial and final distance divided by itz time interval

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
