Answer:

S = 62.9

Step-by-step explanation:

Since this is a right triangle, we can use trig functions

tan S = opp side / adj side

tan S = sqrt(42)/ sqrt (11)

tan S = sqrt(42/11)

Taking the inverse tan of each side

tan ^ -1( tan S) =  tan ^-1(sqrt(42/11))

S=62.89816

Rounding to the nearest tenth

S = 62.9

Suppose a publishing company estimates that its monthly cost is C(x) = 600{x^2} + 300xC(x)=600x 2 +300x and its monthly revenue
Leto [7]

Answer:

the answer is A,

P(x) = -0.4x³+100x²-900x+500

Step-by-step explanation:

monthly cost:

c(x) = 600x {}^{2}  + 300x

monthly revenue:

r(x) =  - 0.4 {}^{3}  + 700x {}^{2}  - 600x + 500

profit function:

p(x) = r(x) - c(x)

p(x) = ( - 0.4x {}^{3}  + 700 {x}^{2} - 600x + 500) - (600x {}^{2}   + 300x)

i) remove the first bracket

p(x) =  - 0.4x {}^{3}  + 700x {}^{2} - 600x + 500 - (600 {x}^{2}   + 300x)

ii) there is a negative sign, '-' in front of the second bracket. so, change the sign of each term of the expression inside the bracket

p(x) =  - 0.4x {}^{3}  + 700 {x}^{2}  - 600x + 500 - 600x {}^{2}  - 300x

iii) collect like terms

p(x) =  - 0.4x {}^{3}  + 700 {x}^{2}  - 600 {x}^{2}  - 600x - 300x + 500

iv) simply the like terms

p(x) =  - 0. 4{x}^{3}  + 100 {x}^{2} - 900x + 500
