Simple Interest:
I = P x r x t
I = 8000 x 0.15 x 2
I = 2400
Compound Interest:
A = P(e^rt)
where e is the Euclid’s constant
and A is the total amount with interest
A = 8000(e^0.15(2))
A = 10799 (rounded up)
Therefore compound interest is 2799.
The difference:
compound - simple = 2799 - 2400
Answer is rs 399.
It’s 11 24/64 i did this too
<u>Differentiate using the Quotient Rule</u> –

According to the given question, we have –
- f(x) = x^3+5x+2
- g(x) = x^2-1
Let's solve it!

The expression that represents Lonnie's final number is 2(x + 3) - 6
<h3>Writing an expression</h3>
From the given information, we are to write the expression that represents Lonnie's final number
From the given information,
"<em>kristy asks lonnie to think of a number, add 3 to it</em>"
Let the number be x
Then,
The statement becomes
x + 3
<em>"multiply the sum by 2</em>" we get
2×(x +3)
= 2(x + 3)
"<em> subtract 6</em>",
The expression becomes
2(x + 3) - 6
This is the expression that represents Lonnie's final number
Hence, the expression that represents Lonnie's final number is 2(x + 3) - 6
