Answer:
x=21.38602241
Step-by-step explanation:
Given: sin(3x)cos(6x) - cos(3x)sin(6x) = -0.9
Rewrite as difference identity: sin(3x-6x)=-0.9
Combine like terms in parentheses: sin(-3x)=-0.9
Take the inverse sine of both sides: -3x=-64.15806724
Divide both sides by -3: x=21.38602241

Answer:
Each child should have 1.25 or 1 pizzas.
Step-by-step explanation:
5 ÷ 4 = 1.25
F(x)=-9/x which is equal to:
f(x)=-9x^(-1) So the power rule for differentiation is used...
Power rule: f(x)=x^e, df/dx=ex^(e-1) so:
df/dx=-9(-1)x^(-1-1)
df/dx=9x^(-2) or if you prefer...
df/dx=9/x^2
df/dx(6)=9/36=1/4
Answer:
The price is x = $2.779
Step-by-step explanation:
From the question we are told that
The revenue is
The cost of production is
Generally at break even point the cost of production is equal to the revenue
So
=>
Using the quadratic formula to solve this equation we have that
x = $2.779
