Arada [10]

Answer:

  y = cos(x) -1

Step-by-step explanation:

The function has a maximum at x=0, a peak-to-peak amplitude of 2, and a period of 2π. It matches a cosine function that has been shifted down 1 unit.

  y = cos(x) -1

A hiker is hiking in a valley. The height of the valley is h(x,y)=4x2+y2 where x and y are the east-west and north-south distanc
Ainat [17]

Answer:

A. \frac{\partial{h}}{\partial{t}}=0

Step-by-step explanation:

A. The problems asked for 2 ways to solve it, expanding the equation with the substitution  x(t)=2 cos(t) and y(t)=4 sin(t) to differentiate it . The other way is by chain rule.

Expanding and differentiating:

We start by substituting x(t)=2 cos(t) and y(t)=4 sin(t) in h(x,y)=4x2+y2:

h(x,y)=4x^{2}+y^{2}= 4(2cos(t))^{2}+(4sin(t))^{2}\\h(x,y)=4(4cos^{2}(t))+(16sen^{2}(t))\\h(x,y)=16cos^{2}(t)+16sen^{2}(t)=16(sen^{2}(t)+cos^{2}(t))\\h(x,y)=16

So, in the path that the hiker chose:

\frac{\partial{h}}{\partial{t}}=0

Chain rule:

We start differentiating h(x,y) using chain rule as follows:

\frac{\partial{h}}{\partial{t}}= \frac{\partial{h}}{\partial{x}}\frac{\partial{x}}{\partial{t}}+\frac{\partial{h}}{\partial{y}}\frac{\partial{y}}{\partial{t}}

Now, it´s easy to find all these derivatives:

\frac{\partial{h}}{\partial{x}}=8x\\\frac{\partial{x}}{\partial{t}}=-2sin(t)\\\frac{\partial{h}}{\partial{y}}=2y\\\frac{\partial{y}}{\partial{t}}=4cos(t)

Now we replace them in the chain rule, with the replacement x=2cos(t) and y=4sin(t) in the x,y that are left and we operate everything:

\frac{\partial{h}}{\partial{t}}= 8x(-2sin(t))+2y(4cos(t)

\frac{\partial{h}}{\partial{t}}= 8(2cos(t))(-2sin(t))+2(4sin(t))(4cos(t)

\frac{\partial{h}}{\partial{t}}= -32cos(t)sin(t)+32sin(t)cos(t)

\frac{\partial{h}}{\partial{t}}= 0

This will be our answer

7x+8=-5x+32 can someone tell me what (x) is pls
WITCHER [35]

Hey there!

<u>Solve </u><u>the </u><u>equation </u><u>:</u>

  • Answer :

x = 2 ✅

  • Explanations:

7x + 8 = -5x + 32

<em>></em><em>></em><em> </em><em>Su</em><em>bstract </em><em>8</em><em> </em><em>from </em><em>e</em><em>ach </em><em>side </em><em>:</em>

7x + 8 - 8 = -5x + 32 - 8

7x = -5x + 24

<em>></em><em>></em><em> </em><em>Add </em><em>5</em><em>x</em><em> </em><em>to </em><em>both </em><em>sides </em><em>:</em>

7x + 5x = -5x + 24 + 5x

12x = 24

<em>></em><em>></em><em> </em><em>Divide </em><em>both </em><em>sides </em><em>by </em><em>1</em><em>2</em><em> </em><em>:</em>

12x / 12 = 24 / 12

x = 2

Therefore, your answer is x = 2
