Answer:

10i

Step-by-step explanation:

multiply the parentheses

to get (2+i+2i+i^2) x (3+i)

i^2=-1

(2+i+2i-1) x (3+i)

collect like terms (1+3i) x (3+i)

multiply this out

3+i+9i+3i^2

3+10i+3(-1)

3+10i-3

10i

Find an equation of the tangent to the curve at the point corresponding to the given value of the parameter. x = cos(θ) + sin(4θ

dybincka [34]

The line tangent to the curve at $(x(0),y(0))$ has slope

$\dfrac{\mathrm dy}{\mathrm dx}\bigg|_{\theta=0}=\dfrac{\mathrm dy}{\mathrm d\theta}\dfrac{\mathrm d\theta}{\mathrm dx}\bigg|_{\theta=0}=\dfrac{\cos\theta-4\sin4\theta}{-\sin\theta+4\cos4\theta}\bigg|_{\theta=0}=\dfrac14$

Then the tangent line has equation

$y-y(0)=\dfrac14(x-x(0))$

$y-1=\dfrac14(x-1)$

$\boxed{y=\dfrac{x+3}4}$

What is the equation of the line? Please help asap!!!! First Correct answer will get brainestttttt !!

faust18 [17]

Answer:

3y= -2x-6

Step-by-step explanation:

The two points on the line are (-3,0) and (0,-2)

so you first get the gradient;

gradient= change in y

change in x

= -2-0

0-(-3)

= -2

so the answer above is the gradient

then pick one point that you used to get the gradient with, so as for me I'll pick (-3,0) and then a general point which is always (x, y)

since you have the gradient you can easily get the equation by doing this

y-0. = -2

x-(-3). 3

then crossmultiply to get the equation of the line

3y= -2(x+3)

3y= -2x-6
