Based only on the given information, it is guaranteed that ad is congruent to db. i need ? what’s the answer, apex.

The correct option is A.

Step-by-step explanation:

Given information: In ΔABC, AB⊥CD, ∠ACD≅∠BCD.

In triangle ΔACD and ΔBCD,

            (Given)

                (Common side)

            (Given)

By ASA postulate of congruent triangles,

The corresponding parts of congruent triangles are congruent.

                    (CPCTC)

It can be written as

Therefore the statement AD≅DB is true and the correct option is A.

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

slope= 1

y-inter slope= 0
