Question:
Which of the following expressions represents the distance between 1.7 and −1/2 on a number line?
Choose 1 answer:
C. None of the above
Answer:
Step-by-step explanation:
Given
Numbers: 1.7 and -1/2
Required
Determine the distance
To calculate the distance, we start by calculating the difference between the given numbers;
Then, we calculate the distance;
<em>In this case, the distance is meant to be positive; So, we'll introduce the symbol for absolute value;</em>
Hence,
Substitute for Difference;
<em>Hence, the correct option is B</em>
Answer:
The last one .
Step-by-step explanation:
1) There are three trigonometric ratios for right-angled triangles.
In a right triangle, the hypotenuse, h, is the side opposite the right angle. Relative to the acute angle θ, check the attachment, the legs are called the opposite side, o, and the adjacent side a.
2) In this case, we are given a length and an angle to find x and y.
Let's find x first. To find x we need to use .
Find y.
Notice that, we can use the Pythagorean Theorem to find y.
3) Round them off to the nearest tenth.
Therefore, the correct choice is the last one .
