The value of the the car is given by:
V=L(1-d.n)
thus, the value of v when L=$21000 and d.n=0.7 will be:
V=21000(1-0.7)
V=21000×0.3
V=$6300
Answer: Present value of the car is $6300
I'm pretty sure it'd just be a parabola with is axis at 0 facing upwards and the inverse would be facing downwards
Find the area of the triangles and smal ler square and add them together ; and find the area of the complete square and set them equal to each other (these are known truths)
triangle: l×w /2
square: s^2
There are 4 triangles so
4 (1/2ab)+c^2= (a+b)(a+b)
simplify
2ab+c^2= a^2+2ab+b^2
-2ab both sides
c^2=a^2+b^2
tada!! it's proven :)
A) the only mistake is changing the mixed number to an improper fraction .
