hay multiplocalo y bxa no se ingles solo español
Answer:
Step-by-step explanation:
- Let the speed of the boat be x
- Speed against the current in the river is x - 2
<u>Time in the river:</u>
<u>Time in the lake:</u>
<u>The difference:</u>
Solve for x to find the speed of the boat
<u>Multiply both sides by x(x - 2) to clear the fraction:</u>
- 6x = 15(x - 2) - x(x - 2)
- 6x = 15x - 30 - x² + 2x
- x² - 11x + 30 = 0
- (x - 5)(x - 6) =0
- x -5 = 0, x - 6 = 0
- x = 5 km/h, x = 6 km/h
Answer:
Step-by-step explanation:
Given that a small business assumes that the demand function for one of its new products can be modeled by
Substitute the given values for p and x to get two equations in c and k
Dividing on by other we get
Substitute value of k in any one equation
b) Revenue of the product is demand and price
i.e. R(x) = p*x = 
Use Calculus derivative test to find max Revenue
R'(x) = 
EquateI derivative to 0
1-0.000589x =0
x = 1698.037
When x = 1698 and p = 16.56469
Answer:
75 inches
Step-by-step explanation:
there are 12 inches in each foot multiply 6 * 12 then multiply .25 or 1/4 by 12 and add them together.
The y-intercept is found by letting x = 0 and finding / calculating y. That would be (0, -10).
The x-int. is found by letting y = 0 and finding x. That would be (10,0).
