3.2-5.7=-2.5 so its have to be a negative because a smaller number subtract a bigger number have to be equal to a negative number.
Answer:
<h3>No it is not in scientific notation</h3>
Step-by-step explanation:
The standard form of a scientific notation is expressed as:
A * 10^n where;
A is any number from between 1 and 10
Given the expression 33.4 × 10^ − 2
Comparing with the general formula, you will see that A = 33.2
Since the value of A does not fall between 1 and 10, hence the expression 33.4 × 10^-2 is not a scientific notation

Answer:
Step-by-step explanation:
In this problem, we have:
H = 452 m is the height of the Petronas tower
h = 1.75 m is the height of the woman
d = 120 m is the distance between the woman and the base of the tower
First of all, we notice that we want to find the angle of elevation between the woman's hat the top of the tower; this means that we have consider the difference between the height of the tower and the height of the woman, so
Now we notice that and are the two sides of a right triangle, in which the angle of elevation is . Therefore, we can write the following relationship:
since
H' represents the side of the triangle opposite to
d represents the side of the triangle adjacent to
Solving the equation for , we find the angle of elevation:
