Answer:

(1+3/2x^4)(1-3/2x^4) = (1+1.5x^4)(1-1.5x^4)

Step-by-step explanation:

2.25 = 9/4

putting decimals into fractions will make this easier

9/4 = 3/2 * 3/2

a²-b² = (a+b)(a-b)

1 - 2.25x^8 = 1²-(3/2x^4)² = (1+3/2x^4)(1-3/2x^4) = (1+1.5x^4)(1-1.5x^4)

An element with mass 800 grams decays by 8.2% per day. How much of the element is remaining after 15 days,

Serjik [45]

Given:

The initial mass of an element is 800 grams.

Decay rate = 8.2% per day

Number of days = 15

To find:

The remaining element after 15 days.

Solution:

The exponential decay model is

$y=a(1-r)^t$

Where, a is the initial value r is the rate of interest and t is time period.

Putting $a=800,r=0.082,t=15$ in the above formula, we get

$y=800(1-0.082)^{15}$

$y=800(0.918)^{15}$

$y=221.68188$

$y\approx 221.7$

Therefore, the mass of the remaining element is 221.7 grams.
