Use implicit differentiation to find an equation of the tangent line to the curve at the given points. (x2 + y2)2 = 3x2y − y3;

Andrew [12]

Answer:

a. $y+1=0$

b. $2x+4y=1$

Step-by-step explanation:

We are given that

$(x^2+y^2)^2=3x^2y-y^3$

a.(0,-1)

Differentiate w.r.t x

$2(x^2+y^2)(2x+2yy')=6xy+3x^2y'-3y^2y'$ .....(1)

Substitute x=0 and y=-1 in equation (1)

$2(0+1)(-2y')=-3y'$

$-4y'+3y'=0$

$-y'=0$

$y'=0$

$m=y'=0$

Point-slope form:

$y-y_0=m(x-x_0)$

Using the formula

$y+1=0$

This is required equation of tangent line to the given curve at point (0,-1).

b.(-1/2,1/2)

Substitute the value in equation (1)

$2(1/4+1/4)(-1+y')=6(-1/2)(1/2)+3(1/4)y'-3(1/4)y'$

$2(2/4)(-1+y')=-3/2+3/4y'-3/4y'$

$-1+y'=-3/2$

$y'=-3/2+1=\frac{-3+2}{2}=-\frac{1}{2}$

$m=y'=-1/2$

Again using point-slope formula

$y-1/2=-1/2(x+1/2)$

$\frac{2y-1}{2}=-\frac{1}{4}(2x+1)$

$2y-1=-\frac{1}{2}(2x+1)$

$4y-2=-2x-1$

$2x+4y=2-1$

$2x+4y=1$

In getting the average of all the measurement you give you need first to sum all the measurements and also make sure that you do it properly. Then divide the sum with the number of measurements. By calculating the answer is 10.288

Todd bought a guitar practice amplifier for $229.99 he paid $30 down and $25 a month for nine months what's his total cost

lana [24]

Wouldn't the total cost be the cost of the amp? Which is 229.99$
Doesn't matter how he paid it - he still had to pay that total amount
