Which function represents g(x), a reflection of f(x) = 6 (1/3)^3 across the y-axis? O g(x) = -6( 1/3)^x
O g(x) = -6(1/3)^-x
O g(x) = 6(3)^x
O g(x) = 6(3)^-x​

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840

its b) 840✌✌✌

i dont know sorry

step-by-step explanation:

correct answer:

b.(19,-2)

answer: 204

step-by-step explanation:

we are told that the revenue is

x⋅(4080−10x)=−10x^2+4080x

this is a quadratic function, so to maximize it we should find the x-value of its vertex. recall that the x-value of the vertex of the parabola ax^2+bx+c is given by the formula −b/2a.

so in this case, we have a=−10 and b=4080, so the x-value of the vertex is

−b/2a= −(4080)/2(−10)=204
