Suppose a body with weight W is pulled along a flat plane by a drag force which acts alongside a string fixed to the body. If the string creates an angle θ with the flat plane, then the drag force is F = μW μ sin θ + cos θ where the coefficient of friction is denoted by μ. Note that μ and W are constants. Determine such a θ for which F is minimum. Also evaluate that minimum value.

answer: $34.31

step-by-step explanation:

$11.99 x 3 = $35.97

$35.97 - 10% = $32.37

$32.37 + 6% = $34.31

step-by-step explanation: yes

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743
