Answer:

the answer is -19.4

Step-by-step explanation:

So -10 to the 2nd power would be -100. Then 3 + -100 = -97. -97 divided by 5 is -19.4.

I think this is correct but please inform me if it is not and I will try to fix it. Have a great day!

Find the maximum rate of change of f at the given point and the direction in which it occurs. f(x, y) = 2 sin(xy), (0, 5)
andrew-mc [135]

Answer:

<h2>10</h2>

Step-by-step explanation:

Given the function f(x, y) = 2 sin(xy) at (0,5), the maximum rate of change of the function at that point will occur in the direction \nabla f(0,5)

\nabla f(x, y) = \frac{\delta(2sin(xy)) }{\delta x} i + \frac{\delta(2sin(xy)) }{\delta y} j\\\\\nabla f(x, y) = 2ycos(xy)i + 2xcos(xy)j\\\\\nabla f(0, 5) =  2(5)cos(0*5)i + 2(0)cos(0*5)j\\\\\nabla f(0, 5) = 10cos0i+ 0j\\\\\nabla f(0, 5) = 10i+0j\\\\||\nabla f(0, 5)|| = \sqrt{10^2+0^2} \\\\||\nabla f(0, 5)||  = \sqrt{100} = 10

Hence, the magnitude of the maximum rate of the function at the point (0, 5) is 10

Plz help me I can't figure it out ​
lys-0071 [83]

Answer:

A.

\sqrt{500}

Step-by-step explanation:

when a value is outside of the root, then you can square it and put it back in. After you put it back in, you need to multiply it by the number that is remaining

In this case, you would square 10 which equals 100, and put it back into the root and multiply 100 by 5.

100x5=500

Therefore, the answer is A, root 500

How to solve 2x+4 = 6x - 10
mars1129 [50]

Answer:

Step-by-step explanation:

2x + 4 = 6x - 10

Minus 2x on both sides

4 = 4x - 10

Add 10 on both sides

14 = 4x

Divide by 4 on both sides

14/4 = x

x = 14/4

Simplify fraction

x = 7/2 or x = 3 1/2

Answer:

yes he is correct for 13

peyton hikes.  6  1/80

no it would not be a greater distance because if you do 9/10 times 3  and turn  the answer into a decimal the red trail is a greater distance.
