This is fill in the blanks

This is a bit hard to fill in the blanks for, so I'm just gonna explain what is happening in the proof...

First, the proof used If parallel, then alternate interior angles are congruent.  Then it uses vertical angles are congruent.  Then it uses C as a midpoint to get two segments congruent.  Then you can get that the triangles are congruent by Angle, Side, Angle.  The with CPCTC(Corresponding Parts of Congruent Triangles Congruent) to get BC congruent to DC.

Hope it helps <3

Step-by-step explanation:

1) AB // DE                  Given

2) AC = CE                 Definition of midpoint

3) ∠ABC = ∠EDC      Alternate interior angles are congruent

4)∠ACB = ∠ECD       Vertically opposite angles are congruent

5) ΔACB ≅ ΔECD      SAA Congruent of triangles

6) BC ≅ DC                CPCT --> corresponding Part of Congruent Triangle

answer: c, the green line

step-by-step explanation:

there is no black line, eliminate b.

simple interest implies periodic payments, but the red line shows no payments, eliminate d.

simple interest has equal payments. if paid say every day, the graph is about a straight line (actually a stairstep).

the yellow line is not straight, eliminate a.

check: the green line is straight, answer is c.

simple interest with positive interest rate gives a straight line sloping up to the right. green line:

g(t) = $100 + ($200-$100) ÷ (20 years) × (t years)

= $100 + (4%/year) × ($100)(t years)

incidentally, the yellow line curving upward represents continuously compounded interest

y = $100 × 2^(t years / (14 assuming the yellow line hits $200 at 14 years. 2^0 is 1, so y(0) = $100; 2^(14/14) is 2, so y(14) = $200.

the answer is: d) o, f, and kr.

atomic radius of bromine (br) is 114 pm.

atomic radius of oxygen (o) is 73 pm.

atomic radius of fluorine (f) is 72 pm.

atomic radius of krypron (kr) is 112 pm.

the atomic radius of a chemical element is a measure of the size of its atom.

the atomic radius varies with increasing atomic number, but usually increases because of increasing of number of electrons.

the atomic radius decreases across the periods because an increasing number of protons, because greater attraction between the protons and electrons.
