Let check your computations:
Recall the formula:
$Curl(f)=(R_y-Q_z)i+(P_z-R_x)j+(Q_x-P_y)k\\\text{Wherein:}\\P=8xye^z\\Q=0\\R=yze^x\\\text{Compute the partial derivative:}\\R_y-Q_z=ze^x-0=ze^x\\P_z-R_x=8xye^z-yze^x\\Q_x-P_y=-8xe^z\\\textbf{Conclusion:}\\Curl(f)=ze^xi+(8xye^z-yze^x)j-8xe^zk\\\textbf{Divergence:}\\\nabla f=P_x+Q_y+R_z=8ye^z+ye^x$

Mark works at a shoe store for 30 hours a week and earns $8.75. During one week Mark sold $480 in shoes. If he receives a 5% com

polet [3.4K]

I'm assuming you mean he earns $8.75 an hour.

So first we have to find out how much money Mark gets without any commission. We do this by multiplying 30 and 8.75 and getting $262.50 .

Then, we have to find the commission. 5% as a decimal is .05, and in order to get 5% of a number, we multiply the 5% and the number together. In other words, we now have to multiply .05 and 480 together, which results in 24.

In conclusion, as a total salary, Mark earns $262.50 + $24, or $286.50

-3r + 7 - 3r - 12 in simplest form

Akimi4 [234]

Since the co-efficient or "r" is "-3" and "-3", it will simplify to "-6" as -3-3= -6.
then the two constant terms with are "7" and "-12" will simplify to "-5" as 7-12=-5. therefore, the simplest form is -6r -5

hope it helped!
