Ahuman hair was measured to be 8.0×10−4 inch thick. a cat hair was measured to be 4.0×10−1 inch thick. how much greater is the thickness of the cat hair than the human hair? write the answer in standard form.

Human hair:  8.0 x 10-4  =  0.00080

Cat hair:        4.0 x 10-1  =  0.40

Subtracting:   0.40  -  0.00080  =  0.3992

Using rules of precision, the answer becomes 0.40

Step-by-step explanation:

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

the answer is 1 becuz if it were 1.0 that would rip apart the entire so ya. : )
