Step-by-step explanation:
use pythagorean theorem
15,640 * 7.2% = 1,126.80 Sales tax
Total cost:
cost of an item: 15,640 - 2,500 = 13,140.00
sales tax 1,126.80
registration fee <u> 106.00</u>
14,372.80 2nd option.
(6n^2-4)+(-2n^2+9)
6n^2-4-2n^2+9
4n^2+5
Hope this helps!
I believe it would be 1% of change

The distance of plane from the starting point is 69.46 km.
Given that the plane first flies 35 km in the direction N30W and then 60 km in the direction N60E.
We have to find the distance of plane from starting point.
We have to use pythagoras theorem in this which says that the square of hypotenuse is equal to sum of squares of the base and perpendicular.

From the figure we can say that P=35 km .and B=60 km
In this we have to find the value of H when P=35 and B=60

=1225+3600
=6946
H=69.46
Hence the distance of plane from starting point is 69.46 km.
