Answer:
$195311
Step-by-step explanation:
Given the expression yˆ=20646*0.86x
Given that the number years 11
And x represent the number of years
Substituting x=11 in the expression for the cost we have
yˆ=20646*0.86(11)
yˆ=20646*9.46
yˆ=20646*9.46
yˆ=195311.16
From the analysis he purchased the car fro $195311

Option (4)
Step-by-step explanation:
Area of a triangle = ![\frac{1}{2} (a.b.\text{Sin}\theta)](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D%20%28a.b.%5Ctext%7BSin%7D%5Ctheta%29)
Where a and b are the sides of a triangle and θ is the angle between the sides a and b.
By this rule,
Area of ΔWZY = ![\frac{1}{2}(\text{WZ}).(\text{YZ}).\text{Sin}(115)](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D%28%5Ctext%7BWZ%7D%29.%28%5Ctext%7BYZ%7D%29.%5Ctext%7BSin%7D%28115%29)
45 = ![\frac{1}{2}(\text{YZ}).(10).\text{Sin}(115)](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D%28%5Ctext%7BYZ%7D%29.%2810%29.%5Ctext%7BSin%7D%28115%29)
9 = (YZ).Sin(115)°
YZ = ![\frac{9}{\text{Sin}(115)}](https://tex.z-dn.net/?f=%5Cfrac%7B9%7D%7B%5Ctext%7BSin%7D%28115%29%7D)
YZ = 9.93
Perimeter of parallelogram WXYZ = WX + XY + YZ + WZ
= 9.93 + 10 + 9.93 + 10
= 39.86
≈ 40 units
Therefore, perimeter of the parallelogram is 40 units.
Option (4) is the answer.
