VERY URGENT?? 1) The explicit formula for a sequence is
an=−2+32(n−1)
What is the 21st term of the sequence?

2)The explicit formula for a sequence is
an=12−5(n−1)
What is the 30th term of the sequence?

3)The explicit formula for a sequence is

an=−1+3(n−1)

What is the 55th term of the sequence?

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6

answer:

step-by-step explanation:

here, the total dishes = 10

dishes having meat = 3 ( chicken, meatloaf and hamburger )

thus, the probability of having meat on the chosen dishes = number of dishes having meat / total dishes

=

therefore, the probability of not having meat = 1- the probability of having meat on the chosen dishes

=

=

=

⇒ option b is correct.

  answer:

  write 548 as 500 + 40 + 8. multiply each addend by 5. then add the three products to get 2,740.
