35 4's were used when writing this book
4300×.30 = 1290
Her costs should be no more than $1290
So this can be solve by solving the distance of the plane
and the town to the west and also the distance of the plane to the town to the
east.
So the town with an angle of depression of 34 degrees
Let x be the distance of the plane and town
Cos 34 = x / 8
x = 8 cos 34
x = 6.63 km
So the town with an angle of depression of 49 degrees
Let y be the distance of the plane and town
Cos 49 = y / 8
y = 8 cos 49
y = 5.25 km
<span>so the distance of the towns is 5.25 + 6.63 = 11.88 km</span>
-4/5 < -7/9 < -5/8 < -3/7
(btw, an easy way to figure this out is to divide the fraction, such as -5 divided by 8 which equals -0.625... if you turn the fraction into a decimal then you can easily figure it out.

Differentiate the exponential equation.
