The height of a sunflower can be modeled by the expression H (1.02)t where t represents the number of years since it was planted and H represents the height when the sunflower was planted. What is the yearly growth of the sunflower?

2%

Step-by-step explanation:

Giveb the model expression :

H = (1.02)^t

General relation:

H = (1 + rate)^t

Rate = yearly growth rate of sunflower

1 + rate = 1.02

Rate = 1.02 - 1

Rate = 0.02

Hence yearly growth rate of sunflower is :

0.02 * 100%

= 2%

2% growth per year.

Barb wants to divide the days in a year by a number.

Step-by-step explanation:

The given expression is  [365 divided by y], where y be any arbitrary number.

The given expression has numerator as 365 and denominator as y which can be any number.

We know that , the number of days in one year = 365

Hence, from the given option the right scenario which could be represented by the algebraic expression is "Barb wants to divide the days in a year by a number.
