Look at the figure shown below: cb is a segment on which a perpendicular bisector ad is drawn. d is the midpoint of cb. which step should be used to prove that point a is equidistant from points c and b? triangle abd is congruent to triangle acd. prove that segment ad is perpendicular to bc. triangle abd is similar to triangle acd. prove that segment ad is equal to segment bc.

ΔABD ≅ ΔACD    CPCTC follows this step to complete the proof

AD ⊥ BC                already given information

ΔABD ~ ΔACD      this proves ratio, not congruency

AD = BC                this might be a false statement, we only know that CD = DB

A) ΔABD ≅ ΔACD

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 1 becuz if it were 1.0 that would rip apart the entire so ya. : )
