Which transformations can be used to show that circle s is similar to circle t? circle s: center (11, −5) and radius 81 circle t: center (11, 0) and radius 9 select each correct answer. circle s is congruent to circle t. circle s is a translation of circle t, 5 units down. circle s is a dilation of circle t with a scale factor of 72. circle s is a dilation of circle t with a scale factor of 9.

The answers are B and C.

I'm sorry I can't explain why but I just took the test and got the answers right, so... Also, Lemme recommend Desmos Graphing Calculator for a minute cause all I have to do is type in the equation and count from there. The graphing calculator is your friend. Embrace it.

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
