Gary had a 40% discount for car speakers. The sale price of the speakers was $96.25. What was the original price of the speakers
Ostrovityanka [42]

Answer:

Step-by-step explanation:

If the price after the discount is subtracted is $96.25 then this is what you do

u times 0.40 x 96.25 which is 38.5 so since you are wanting to know what the price was before the discount you would add 38.5 to 96.25 and when you do that your answer is 134.75

but if you are just trying to get the discount from 96.25 you subtract 38.5 from 96.25

Find the maximum rate of change of f(x,y,z=x y/z at the point (2, -3, 5 and the direction in which it occurs. maximum rate of ch
kherson [118]
f(x,y,z)=x+\dfrac yz
\implies \nabla f(x,y,z)=\left(1,\dfrac1z,-\dfrac y{z^2}\right)
\implies \nabla f(2,-3,5)=\left(1,\dfrac15,\dfrac3{25}\right)

The maximum rate of change is then

\|\nabla f(2,-3,5)\|=\dfrac{\sqrt{659}}{25}

which occurs in the direction of \nabla f(2,-3,5) above.
