I think the answer is letter D.
:) have a good day
The line of sight is the hypotenuse of a right triangle with short leg 400 m, 90 degree angle where the short leg meets the ground, an 83 degree angle at the top, and a 7 degree angle across from the right angle on the ground. Because this 7 degree angle is an alternate interior angle with the angle of depression, they are the same degree measure. Looking for the hypotenuse, we use the sin ratio: sin (7) = 400/x.
Answer:
-3 1/4 + 4 3/4
Step-by-step explanation:
Answer:

Step-by-step explanation:
We have been given that a certain function is an inverse proportion. We are asked to find the formula for the function if it is known that the function is equal to 12 when the independent variable is equal to 2.
We know that two inversely proportional quantities are in form
, where y is inversely proportional to x and k is constant of variation.
Upon substituting
and
in above equation, we will get:

Let us solve for constant of variation.


Now, we will substitute
in inversely proportion equation as:

Therefore, the formula for the given scenario would be
.
The second answer is correct because in order for the ordered pairs to represent a function, there can only be 1 y value for every x value. The second option has 2 different y values for x = 3 so it is not a function.
The answer is the second option.
