IRINA_888 [86]

$\sin q+\cos q\cot q=\sin q+\cos q\cdot\dfrac{\cos q}{\sin q}=\sin q+\dfrac{\cos^2q}{\sin q}\\\\=\dfrac{sin^2q}{\sin q}+\dfrac{\cos^2q}{\sin q}=\dfrac{\sin^2q+\cos^2q}{\sin q}=\dfrac{1}{\sin q}=\csc q\\\\Used:\\\cot q=\dfrac{\cos q}{\sin q}\\\\\sin^2q+\cos^2q=1\\\\\csc q=\dfrac{1}{\sin q}$

The function M(s) = 225 + 0.65s represents the material cost of manufacturing gardening scissors when s scissors are produced. T

Llana [10]

Answer:

$\frac{279 + 1.8s}{s}$

Step-by-step explanation:

The material cost of manufacturing gardening scissors when s scissors are produced : $M(s) = 225 + 0.65s$

The labor cost for producing s scissors: $L(s) = 54 + 1.15s$

So, total cost of producing s scissors = $M(s)+L(s)$

= $225 + 0.65s+54 + 1.15s$

= $279 + 1.8s$

So, total cost for s scissors = $279 + 1.8s$

So, manufacturing cost for 1 scissor= $\frac{279 + 1.8s}{s}$

Hence the manufacturing cost per scissors is $\frac{279 + 1.8s}{s}$
