The answer is the option D.
You have to use implicit derivative
1) dy / dx = y'
2)
5x(8-3)+3x-2
use the distributive property on 5x(8-3)
40x - 15x + 3x - 2
simplify
28x - 2
there's your answer
Answer:
It should be 13
Step-by-step explanation:
Answer: Bob can make it to base camp in about 1.6 hours.
If I am understanding the problem correct, Bob must drive 10 km to get to the road through the desert. Then, 45 km on the road. And finally, another 10 km off the road to get to the base camp.
We end to find the time for each section of the trip.
Start with the formula: d = rt or t = d/r
Now, we can divide to determine the amount of time for each section.
1) 10 / 30 = 0.333 hours
2) 45/50 = 0.9 hours
3) 10/30 = 0.333 hours
Add up all the times, and you get about 1.6 hours.
Answer:
35
Step-by-step explanation:
Breakeven quantity are the number of units produced and sold at which net income is zero
Breakeven quantity = fixed cost / price – variable cost per unit
Fixed costs are costs that do not vary with output. e,g, rent, mortgage payments
If production is zero or if production is a million, Mortgage payments do not change - it remains the same no matter the level of output.
Hourly wage costs and payments for production inputs are variable costs
Variable costs are costs that vary with production
fixed cost = $2450
Variable cost = $75
price = $145
(2450) / (145 - 75) = 35
