Rewrite x^2 - 8x + 13 = 0 in the form ( x - a )^2 = b where a and b are integers to determine the a and b values

A.) a = 4 and b= 3

B.) a = 3 and b = 2

C.) a= 2 and b= 1

D.) a= 1 and b = 4

by definition, an arc subtended by a central angle of some given measure has the same measure. so .

boxplot e is the answer

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
