Write an equation for the vertical translation y=-2/9 |x| -7; 1 units down
klasskru [66]

Answer:

y = -2/9 |X| - 8

Step-by-step explanation:

I'm not certain whether the -7 is part of the |X| or it's just out of the equation. But shifting an equation up or down is very intuitive.

If you want to move an equation up a certain unit, you just add that many units (positive) onto the end of an equation. The same goes for moving a unit down, where you subtract that many units you want to go down.

Use the Fundamental Theorem of Line Integrals to calculate ∫c F⃗ ⋅dr⃗ exactly, if F⃗ =3x2/3i⃗ +ey/5j⃗ , and C is the quarter of
nignag [31]

It looks like the vector field is

<em>F</em><em>(x, y)</em> = 3<em>x</em> ^(2/3) <em>i</em> + <em>e</em> ^(<em>y</em>/5) <em>j</em>

<em></em>

Find a scalar function <em>f</em> such that grad <em>f</em> = <em>F</em> :

∂<em>f</em>/∂<em>x</em> = 3<em>x</em> ^(2/3)   =>   <em>f(x, y)</em> = 9/5 <em>x</em> ^(5/3) + <em>g(y)</em>

=>   ∂<em>f</em>/∂<em>y</em> = <em>e</em> ^(<em>y</em>/5) = d<em>g</em>/d<em>y</em>   =>   <em>g(y)</em> = 5<em>e</em> ^(<em>y</em>/5) + <em>K</em>

=>   <em>f(x, y)</em> = 9/5 <em>x</em> ^(5/3) + 5<em>e</em> ^(<em>y</em>/5) + <em>K</em>

(where <em>K</em> is an arbitrary constant)

By the fundamental theorem, the integral of <em>F</em> over the given path is

∫<em>c</em> <em>F</em> • d<em>r</em> = <em>f</em> (0, 1) - <em>f</em> (1, 0) = 5<em>e</em> ^(1/5) - 34/5

Please help me I’m stuck
Gre4nikov [31]

Answer:

x = 3.7

Step-by-step explanation:

We can find the side of the hypotenuse by applying pythagorean theorem.

{5}^{2}  +  {5}^{2}  =  {x}^{2}

25 + 25 =  {x}^{2}

50 =  {x}^{2}

x = 5 \sqrt{2}

Now we can apply pythagorean theorem on the other triangle

(5 \sqrt{2} ) {}^{2}  +  {x}^{2}  =   {8}^{2}

50 +  {x}^{2}  = 64

{x}^{2}  = 14

x =  \sqrt{14}

x = 3.7
