Answer:

y=\left\{\begin{matrix}24x & x\leq 38 \\ 31x & x > 38\end{matrix}\right.

Step-by-step explanation:

Here, x represents the number of hours she works in a week and y represents the amount she is paid,

Since, for the hours less than equal to 38,

She is paid $ 24 per hours,

That is, y = 24 x for x ≤ 38,

Also, she is paid $ 31 per hours for the hours more than 38,

That is, y = 31 x for x > 38,

Hence, the piece wish function that shows the given situation is,

y=\left\{\begin{matrix}24x & x\leq 38 \\ 31x & x > 38\end{matrix}\right.

X \leq 38       ->     24x
x > 38        ->      31(x-38) + 912

912 = 24*38   (You will have to have 38 hours to be able to be in this part of the piece wise function)

Jackson runs a farm stand that sells bananas and grapes. Each pound of bananas sells for $1 and each pound of grapes sells for $
mars1129 [50]

Jackson sold 27 pounds of bananas and 12 pounds of grapes.

Given that Jackson runs a farm stand that sells bananas and grapes, and each pound of bananas sells for $ 1 and each pound of grapes sells for $ 2.25, and Jackson sold 15 more pounds of bananas than pounds of grapes and made $ 54 altogether, to determine the number of pounds of bananas sold and the number of pounds of grapes sold the following calculation must be performed:

  • 25 x 1 + 10 x 2.25 = 25 + 22.50 = 47.50
  • 26 x 1 + 11 x 2.25 = 26 + 24.75 = 50.75
  • 27 x 1 + 12 x 2.25 = 27 + 27 = 54

Therefore, Jackson sold 27 pounds of bananas and 12 pounds of grapes.

Hund’s rule of maximum multiplicity specifies that _____. A. electrons will fill orbitals of lower energy first, pairing up only
djverab [1.8K]

Answer:

A. electrons will fill orbitals of lower energy first, paring up only after each orbital of the same energy already has one electron

Step-by-step explanation:

The rule states that for a given electron configuration, the lowest energy term is the one with the greatest value of spin multiplicity. This implies that if two or more orbitals of equal energy are available, electrons will occupy them singly before filling them in pairs.
