Answer: One bag of peaches : $22
Step-by-step explanation:
Hi, to answer this question we have to write an equation for William and Sylvia.
- <em>William: 2 p + 3 a = 17
</em>
- <em>Silvia: 4p + 2 a =22
</em>
Where:
p = price of one bag of peaches
a= price of one bag of apricots
Solving for "a" in William's equation:
2p +3a =17
3a = 17-2p
a = (17-2p)/3
a= 17/3 -2/3 p
Replacing "a" in Silvia's equation
4p + 2 a =22
4p + 2 (17/3 -2/3p) =22
4p +34/3-4/3p =22
4p-4/3p =22-34/3
8/3 p =32/3
p =32/3 ÷8/3
p=4
Answer: Identify which of the following functions are eigenfunctions of the operator d/dx: (a) eikx, (b) cos kx, (c) k, (d) kx, (e) e−ax2
Step-by-step explanation: First, we going to apply the operator derivate to each item. Remember that a function f is an eigenfunction of D if it satisfies the equation
Df=λf, where λ is a scalar.
a) D(eikx)/dx= ik*eikx, then the function is a eigenfunction and the eingenvalue is ik.
b) D(cos kx)/dx= -ksen kx, then the funcion is not a eigenfunction.
c) D(k)/dx=0, then the funcion is not a eigenfunction.
d) D(kx)/dx=k, then the funcion is not a eigenfunction.
e) D(e-ax2)/dx= -2ax*e-ax2, then the function is a eigenfunction and the eingenvalue is -2ax
Answer:
The chances are 1/6 because 6-8 is 1/6 of the possible timings.
