1. Write a two-column proof.
Alexandra [31]

Answer:

Check it below, please

Step-by-step explanation:

Hi there!

Let's prove segment AB is perpendicular to CD. Attention to the fact that a two column proof has to be concise. So all the comments can't be exhaustive, but as short as possible.

Let's recap: An isosceles triangle is one triangle with at least 2 congruent angles.

Statement                     Reason

\overline{AB} \cong \overline{AC}\\                     Given

\widehat{ACB} \:bisects\: \overline{AB}        Isosceles Triangle the altitude, the bisector coincide.          

\overline{AD} \cong \overline{DB}               Bisector equally divide a line segment into two congruent      

m\angle CDA =m \angle CBD=90^{\circ} Right angles, perpendicular lines.                  

\overline{CD}\perp \overline{AB}                    Perpendicular Line segment

What is the kinetic Energy of a camion of 5,000 kg and turn at 100km/h ?
Alex787 [66]

Step-by-step explanation:

Given

mass (m) = 5000 kg

velocity (v) = 100 km/h = 100* 1000/ 3600 = 27.78m/s

Now

Kinetic energy

= 1/2 mv²

= 1/2 * 5000 * 27.78²

= 1929321 joule

Write the equations after translating the graph of y = |x|: one unit up,
Tatiana [17]

Answer:

g(x) = |x| + 1

Step-by-step explanation:

Given

y = |x|

Required

Translate 1 unit up

Start by replacing y with f(x)

f(x) = |x|

To translate an the graph of an absolute function upward, you make use of the formula;

g(x) = f(x) + k

Where k is the number of units

In this case; k = 1

Hence;

g(x) = f(x) + k

Substitute k = 1

g(x) = f(x) + 1

Substitute  f(x) = |x|

g(x) = |x| + 1

<em>Hence, the resulting equation is </em>g(x) = |x| + 1<em></em>
