Answer:
Step-by-step explanation:
As the given expression is
And we have to determine the equivalent expression.
- As the distributive property is one of the most frequently properties used in Mathematics, especially solving algebraic expressions.
- The distributive property states that the product of a number for instance x and the sum (or difference) of two numbers for instance y and z, is equal to the sum (or difference) of the product of x and y and x and z. In other words: x(y + z) = xy + xz ; x(y - z) = xy - xz
So,
∵x(y - z) = x.y - x.z

Interest on interest, or compound interest, is the adding of interest to the principal sum of a loan or deposit. The amount that will be in the account after 10 years is $651.56.
<h3>What is compound interest?</h3>
Interest on interest, or compound interest, is the adding of interest to the principal sum of a loan or deposit. It's the outcome of reinvesting interest rather than paying it out so that interest is received on the principal plus previously collected interest in the next quarter.
The principal amount is $400 which is invested for a period of 10 years at an interest rate of 5% annually. Therefore, the amount in the account after 10 years will be,
Hence, the amount that will be in the account after 10 years is $651.56.

The tree died about 3357 years ago.
Explanation:
The half life of carbon - 14 is given by
where
Substituting these values in the above equation, we get,
Taking In on both sides of the equation, we get,
Since, only 66% of Carbon - 14 remains after the time T.
Thus, we have,
Taking In on both sides of the equation, we get,
Thus, the tree died about 3357 years ago.
