Answer:
Step-by-step explanation:
y & x
y = kx
When y = 6 , x = 72
6 = 72k
k = 6/72
k = 1/12
:- y = x/12
When x = 8
y = 8/12
y = 2/3
Hey there!
As according to the mathematical acronym SOH CAH TOA (Sin Opposite Hypotenuse, Cos Adjacent Hypotenuse, Tan Opposite Adjacent), the correct answer would be the first choice,

.
The reason behind this is because the tangent value of an angle is always the length value opposite of given angle over the value adjacent (or right next to) the given angle.
In this case, the question is asking for Tan D. The side value opposite of angle D would be 12, and the length value that is adjacent to angle D is 5.
Therefore, the value of tan D would be

.
Hope this helps and I hope you have a marvelous day! :)
The answer is B. an = 13 + 14(n-1)
8.9% is equal to 0.089 because a percent is over a 100. So, you can just multiply the ROI by the investment to get:

Your answer is:
$712.
Answer:
y =
- 8
Step-by-step explanation:
The given line passes through (-4, 4) and (4, -2)
The slope of this line will be given by: Change in y ÷ change in x
Slope =
=
= 
The slope of the given line times the slope of the perpendicular line = -1
Let's say the slope of the perpendicular line is p
Then,
× p = -1
p = -1 ÷
= 
The perpendicular line passes through point (6, 0)
Taking another point (x, y) on the perpendicular line;
= 
Cross multiplying this gives the equation of the perpendicular line to be:
y =
- 8
