Using proportions, the multiplication expression to determine the total change in the value of these cars at the dealership is given by:
T = -1,200 x 42.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.
For this problem, we have that one car depreciated on average -$1,200. We want to find the amount relative to 42 cars, and this amount can be found by the following<em> rule of three</em>.
1 car - -$1,200.
42 cars - $T
Applying cross multiplication, the expression is given by:
T = -1,200 x 42.

tanX is 12/5.
Given:
In a right triangle,
The length of the side <em>XY</em> = 13.
The length of the side <em>YZ</em> = 12.
The length of the side <em>XZ</em>= 5.
The objective is to find tan <em>X</em>.
In a right angled triangle the largest side is always hypotenuse.
Sinec tan <em>X</em> is required to solve, then, the side <em>YZ </em>is opposite side and the side <em>XZ</em> is adjacent side.
By the trigonometric ratios, the value of tan <em>X</em> can be calculated as,
Hence, the value of tanX is 12/5.

Answer:
The y-coordinate of the point is approximately 2.42.
Step-by-step explanation:
From the figure attached below the statement we derive the following equation to calculate the y-coordinate (
), dimensionless, of the point in terms of the x-coordinate (
), dimensionless, and angle of the line (
), measured in sexagesimal degrees:
(1)
If we know that 
and 
, then the y-coordinate of the point is:
The y-coordinate of the point is approximately 2.42.
Answer:
He is asking about the power not the answer. I did a small calculation like 8*3 should be a 2 digits number. Took 10^1 out & simply 10^1*10^12*10^2= 10^15
