Answer:

Step-by-step explanation:

From the figure, it is given that AB≅ED, BC≅CD and ∠CAD≅∠CEB.

Now, from ΔACD and ΔECB, we have

Statements                                                      Reason

1. AB≅ED, BC≅CD                                           Given

2. ∠CAD≅∠CEB.                                              Given

3. AB=ED, BC=DC                     Definition of congruent segments

4. AB+BC=AC and                                Segment addition postulate

ED+DC=CE                          

5. ED+DC=AC and                                 Substitution property

ED+DC=CE

6. AC=CE                                                Substitution property

7. AC≅CE                                  Definition of congruent segments

8. ∠C≅∠C                                               Reflexive property

9. ΔACD≅ΔECB                           ASA rule of congruency

Hence proved.

Hence, option A is correct.

Determine whether f(x) = –5x^2 – 10x + 6 has a maximum or a minimum value.
Blizzard [7]

First,

We are dealing with parabola since the equation has a form of,

y=ax^2+bx+c

Here the vertex of an up - down facing parabola has a form of,

x_v=-\dfrac{b}{2a}

The parameters we have are,

a=-5,b=-10, c=6

Plug them in vertex formula,

x_v=-\dfrac{-10}{2(-5)}=-1

Plug in the x_v into the equation,

y_v=-5(-1)^2-10(-1)+6=11

We now got a point parabola vertex with coordinates,

(x_v, y_v)\Longrightarrow(-1,11)

From here we emerge two rules:

  • If a then vertex is max value
  • If a>0 then vertex is min value

So our vertex is minimum value since,

a=-5\Longleftrightarrow a

Hope this helps.
