Step-by-step explanation:

=  \lim \limits_{x \to0} \frac{x -  \sin(2x) }{x +  \sin(3x) }

=  \lim \limits_{x \to0} \frac{ \frac{d}{dx}(x -  \sin(2x) ) }{ \frac{d}{dx} (x +  \sin(3x) )}

=  \lim \limits_{x \to0} \frac{1 -  2\cos(2x) }{1 + 3 \cos(3x) }

=  \lim \limits_{x \to0} \frac{ \frac{d}{dx}(1 + 2 \cos(2x) ) }{ \frac{d}{dx} (1 + 3 \cos(3x) )}

=  \lim \limits_{x \to0} \frac{ - 4 \sin(2x) }{ - 9 \sin(3x) }

=  \frac{ - 4.2}{ - 9.3}

=  \frac{ - 8}{ - 27}

=  \frac{8}{27}

Ann car can go 117 miles on 3 gallons of gas. During a drive last weekend, Ann used 8 gallons of gas. How far did she drive?
Nitella [24]

Answer:

Ann drove 312 miles in 8 gallons.

Step-by-step explanation:

Distance covered by Ann's car = 117 miles

Gallons of gas spent by Ann's car to cover 117 miles = 3 gallons

Unit rate = 117 miles / 3 gallons

               = 39 miles per gallon

so Ann's car can go 39 miles in one gallon of gas.

  • Given that Ann used 8 gallons of gas.

Therefore,

Distance covered by Ann's car in 8 gallons = 39 × 8

                                                                         = 312 miles

Therefore, Ann drove 312 miles in 8 gallons.
