Answer:
it would take 20 miles and cost 10 dollars.
Step-by-step explanation: Like up the equations so that 50x=40x+200. When you solve for x (number of miles) you find that x=20. Use 20 in either equation (0.5x or 0.4x+2) to get 10 (total cost).
We will use the product rule:
d/dx( f(x) · g(x) ) = f´( x ) g( x ) + g´( x ) f( x ) ( and after that the chain rule )
y´ = ( x ) ´· e^(-x/2) + ( e^(-x/2)´ · x) =
=
Answer:
- 10/10 on two tracks ⇒ 1/2 + 5/10
- 10/10 on three tracks ⇒ 1/2 + 1/10 + 4/10
- 10/10 on four tracks ⇒ 3/10 + 2/10 + 1/10 + 4/10
Step-by-step explanation:
As 10/10 is the fraction card. We can move it in many ways.
- 10/10 on two tracks ⇒ 1/2 + 5/10
- 10/10 on three tracks ⇒ 1/2 + 1/10 + 4/10
- 10/10 on four tracks ⇒ 3/10 + 2/10 + 1/10 + 4/10
Verification:
- 10/10 on two tracks ⇒ 1/2 + 5/10
As LCM is 10
<em>10/10 on two tracks ⇒ 1/2 + 5/10 = </em><em>(5 + 5)/10 = 10/10</em>
- 10/10 on three tracks ⇒ 1/2 + 1/10 + 4/10
As LCM is 10
10/10 on three tracks ⇒ 1/2 + 1/10 + 4/10 ⇒ (5 + 1 + 4)/10 = 10/10
- 10/10 on four tracks ⇒ 3/10 + 2/10 + 1/10 + 4/10
As LCM is 10
10/10 on 4 tracks ⇒ 3/10 + 2/10 + 1/10 + 4/10 ⇒ (3 + 2 + 1 + 4)/10 = 10/10
