36.47 ÷ 0.7 show your work, please!

Lelechka [254]

Answer:

52.1

Step-by-step explanation:

When dividing decimals, convert the divisor to an integer by moving the decimal point a suitable number of places. Move the decimal point in the dividend the same number of places in the same direction. Make sure the decimal point in the quotient is aligned with the new location of the decimal point in the dividend.

36.47 ÷ 0.7 = 364.7 ÷ 7 = 52.1

Solve for p.<br> 2(p+ 1) = 24<br> What is the answer?

kicyunya [14]

Answer:

p=11

Step-by-step explanation:

Distribute: 2p+2=24

Subtract 2 from both sides: 2p=22

Divide both sides by 2 (to get p by itself): p=11

Find the equation of the tangent line to the curve <br> 2exy=x+y at (0,2).

DiKsa [7]

Answer:

The equation of the tangent line to the curve

3 x - y = 2

Step-by-step explanation:

<u><em>Step(i):-</em></u>

Given function = f(x,y) = $2e^{xy} -x-y=0$ ...(i)

Differentiating equation (i) with respective to 'x' , we get

$2 e^{xy} \frac{d}{d x} (x y) -1 -\frac{dy}{dx} =0$

apply formula

$\frac{d}{dx} (UV) = UV^{l} +V U^{l}$

<u><em>step(ii):-</em></u>

⇒ $2 e^{xy} (x(\frac{d}{d x} ( y))+y(1)) -1 -\frac{dy}{dx} =0$

⇒ $2 e^{xy} (x(\frac{d}{d x} ( y))+ 2e^{xy} y(1)) -1 -\frac{dy}{dx} =0$

Taking common d y/d x

$(2 e^{xy} (x) -1)\frac{dy}{dx} =1- 2e^{x y} y(1))$

$\frac{dy}{dx} =\frac{1- 2e^{x y} y(1))}{(2 e^{xy} (x) -1)}$

put At (0,2)

$\frac{dy}{dx} =\frac{1- 2e^{0} 2(1))}{(2 e^{0} (0) -1)}=\frac{1-4}{-1} =3$

slope of the curve m = 3

<u><em>Step(iii)</em></u>:-

The equation of the tangent line to the curve

$y-y_{1} =m(x-x_{1} )$

y - 2 = 3 ( x - 0 )

3 x - y = 2

<u><em>Final answer:-</em></u>

The equation of the tangent line to the curve

3 x - y = 2
