Which statement about and is true? A picture shows triangle A B C and triangle D E F. Triangle A B C: Side A B is 5. Side B C is 8. Side C A is 6. Triangle D E F: Side D E is 10. Side E F is 16. Side F D is 12.

They are not similar because is more than , while is more than .

They are similar because is twice as long as , is twice as long as , and is twice as long as .

They are congruent.

They are not similar because corresponding sides are not proportional.

the answer to the question is a  

it has the same slope and the same y-intercept.

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)

-4, -2, 1, 4

step-by-step explanation:

domain = x values

range = y values
