The answer to that would be 48
In a scientific notation, you have to put a decimal right after the first number (unless it is a zero). How many times you move the decimal from its original spot determines the answer. If you move the decimal
forward that means you put a
negative number

0.00000123 = 1.23 (moved the decimal point
forward 6 times, so the answer is --->)

Applying precedence of operations, the result of the expression is of 161.
<h3>What is the precedence of operations?</h3>
Power operations are done before multiplication/division, which are also done before addition/subtraction.
Operations inside brackets or parenthesis also take precedence.
In this problem, the operation is:
[3 x 2^5 + 13 x (-2)] + 7[8 - (4 - 9)]
First the power:
[3 x 32 + 13 x (-2)] + 7[8 - (4 - 9)]
Now the multiplications on the first bracket, and the subtraction on the second:
[96 - 26] + 7[8 - (-5)]
Then, applying the parenthesis to the negative number, we have that:
[96 - 26] + 7[8 - (-5)] = 70 + 7 x 13 = 161.

First let us calculate for his salary this year. We know
that 3000 is only 8% of his salary, hence:
0.08 * salary = 3000
salary = 3000 / 0.08
salary = 37,500
Therefore his previous salary is:
previous salary = 37,500 + 2,000
<span>previous salary = $39,500</span>
Answer:
Step-by-step explanation:
The easiest way to tell if a relation is a function is to look at the x coordinates. If none of them are the same in the set, then the relation is a function. If any of the x values are used more than once in the set, it is only a relation. This set uses -3 two times, so it is a relation.
