Holly's favorite book is about Johnny Appleseed, the American pioneer who planted apple trees all across the country. Inspired b

y the story, Holly plants an apple seed in her backyard and tends the seed as it slowly grows into a tree. The proportional relationship between the age of Holly's apple tree (in years), x, and the height of the tree (in feet), y, can be modeled by the equation y = 1.5x.
If the tree is 5.25 feet tall, how many years has the tree grown?

Answer:

3.5.

Explanation

The tree has grown for 3.5 years.

y = 1.5x → 5.25 = 1.5x → x =

Answer:

  3.5 years

Step-by-step explanation:

Fill in the given number and solve for x.

  y = 1.5x

  5.25 = 1.5x . . . . . . with given height in feet

  5.25/1.5 = x = 3.5 . . . . . divide by 1.5 to find age in years

The tree has grown for 3.5 years.

Rylee earns $5,4000 in her first year of teaching and earns a 3% increase in each successive year. Write a geometric series form
Stella [2.4K]

Answer: $1387800

Step-by-step explanation:

This is an sum of Arithmetic Progression with the formula

Sum of nth term

Sn = n/2( a + l ) --------------- 1

where l = a + ( n - 1 )d -------2

Now put (2) in 1

Sn = n/2{( a + a + (n - 1)d}

= n/2{( 2a + ( n -1 )d}

From the question

a = $5,4000 ( firs term )

d = 3% of $5,4000 ( common difference ), n = 20 years. Solution to question one therefore is.

First find 3% of $54000 = $1620, so the geometric series is

Sn = n/2{(2a + ( n - 1 )d

Second solution is substitution,

Sn. = 20/2 {(2 x 54000 + (20 -1)1620)}

= 10{ 108000 + 19 x 1620}

= 10{ 108000 + 30780 }

= 10{ 138780 }

= 1387800

Therefore, the total emoluments of Rylee for the past 20 years

= $1387800
