please solve the question and show your work so pluto is the farthest planet from the sun it also the slowest planet. plutos ave

allsm [11]

Knowing that pluto is travelling at 10,604 and the Earth travels 6.28 times faster;

6.28x=10,604 mph (where x is the speed of the earth)
x=10,604/6.28
x=1688.53 mph for the Earth

Double check by multiplying the answer found by 6.28 to see if it gives pluto's speed.

1688.53×6.28=10, 604 mph

Therefore, our solution is correct.

Hope I helped :)

The revenue for a company producing widgets is given by y = -20x2 - 50x + 200, where x is the price in dollars for each widget.

lisov135 [29]

Answer:

The price is x = $2.779

Step-by-step explanation:

From the question we are told that

The revenue is $y = - 20x^2 - 50 x + 200$

The cost of production is $y = 30 x - 10$

Generally at break even point the cost of production is equal to the revenue

So

$-20x^2 -50x + 200 = 30x-10$

=> $20x^2 +20 -210 = 0$

Using the quadratic formula to solve this equation we have that

x = $2.779
