Choose the correct simplification of the expression (3x)^4.
81x^4
12x^5
81x^5
12x^4

Step-by-step explanation:

The given expression:

The law of exponent says that

Therefore by applying the above law we get the given expression as:

Since,

Therefore,

Hence, the correct simplification of the expression

a. -0.3 > -0.33

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
