Marco starts with a population of 10 bacteria that doubles every day for a number of days, d. he writes the expression 10(2d) to find the number of bacteria after d days. isabella starts with a population of 1 bacterium that increases 20% every day for a number of days, d. she writes the expression (1 + 0.2)d to find the number of bacteria after d days. use the drop-down menus to explain what each part of marco's and isabella's expressions mean.

Step-by-step explanation:

∠1≅∠2 by the alternate exterior angles theorem.

step-by-step explanation:

given, a ∥ b and ∠1 ≅ ∠3 .we have to prove that e ∥ f

we know that ∠1≅∠3 and that a || b because they are given. we see that by the alternate exterior angles theorem. therefore, ∠2≅∠3 by the transitive property. so, we can conclude that e || f by the converse alternate exterior angles theorem.

we have to fill the missing statement.

transitivity property states that if a = b and b = c, then a = c.

now, given ∠1≅∠3 and by transitivity property ∠2≅∠3 .

hence, to apply transitivity property one angle must be common which is not in result after applying this property which is ∠1.

the only options in which ∠1 is present are ∠1 and ∠2, ∠1 and ∠4

∠1 and ∠4 is not possible ∵ after applying transitivity we didn't get ∠4.

hence, the missing statement is ∠1≅∠2.

so, ∠1≅∠2 by the alternate exterior angles theorem.

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
