Aaron owns a basketball card. He bought the card for $7.50 in 1987 and it’s value increases by 6% each year. Write and use an exponential growth function to find the baseball cards value in 2015.

The exponential growth is given by the growth rate of subsequent period

raised to power of time.

The given parameter are;

The amount Aaron buys the basketball card in 1987, a = $7.50

The rate at which the value increases each year, r = 6%

To write the exponential growth function.

A general form of the exponential growth function is;

Where;

a = The starting amount = $7.50

r = The growth rate = 6% = 0.06

t = The time duration of the growth = 2015 - 1987 = 28

The time duration, t = 28 years

The exponential growth function to find the basketball card's value in 2015 is therefore;

Which gives;

f(28) = 7.5 × (1 + 0.06)²⁸ ≈ 38.34

Part 1)

Part 2)

Step-by-step explanation:

Part 1) Write an exponential growth function

we know that

The equation of a exponential growth function is given by

where

y is the baseballs card value

x is the number of years since 1987

a is the initial value

r is the rate of change

we have

substitute

Part 2) Find the baseball cards value in 2015.

Find the value of x

substitute the value of x in the equation

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

step-by-step explanation:

given   that triangle lno is congruent to triangle lnm.

we have to fill up the blanks in the given question.

according to above order of congruency   kept in mind we can say that

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

ln ≅ ln due to common in both.

hence, by sas congruency,

the side angle side rule   states that if two sides and the included angle of one triangle are congruent to another triangle, then these two triangles are congruent.
