NO LINKS!!! Find the equation of the PARABOLA with a vertex at (-2, 6) and passing through the point (1, -3)​
levacccp [35]

General equation of parabola

  • y=a(x-h)²+k

for vertex(h,k)

Now

\\ \rm\Rrightarrow y=a(x+2)^2+6

  • Put (1,-3) and find a

\\ \rm\Rrightarrow -3=a(1+2)^2+6

\\ \rm\Rrightarrow -9=a(3)^2

\\ \rm\Rrightarrow -9=9a

\\ \rm\Rrightarrow a=-1

So

equation of parabola

\\ \rm\Rrightarrow y=-(x+2)^2+6

Which rational graph has a minimum near x=-2 and a horizontal asymptote at y=1?
Arada [10]

Answer:

Graph A.

Step-by-step explanation:

The graph has a local minimum around x=-2 since it slightly curves downwards around this region. Moreover, the graph of the rational function has a horizontal asymptote at y=1 since the graph approaches this horizontal line but never touches nor crosses it

Find the product of z1 and z2, where z1 = 7(cos 40° + i sin 40°) and z2 = 6(cos 145° + i sin 145°).
Oduvanchick [21]
For two complex numbers z_1=re^{i\theta}=r(\cos\theta+i\sin\theta) and z_2=se^{i\varphi}=s(\cos\varphi+i\sin\varphi), the product is

z_1z_2=rse^{i(\theta+\varphi)}=rs(\cos(\theta+\varphi)+i\sin(\theta+\varphi))

That is, you multiply the moduli and add the arguments. You have z_1=7e^{i40^\circ} and z_2=6e^{i145^\circ}, so the product is

z_1z_2=7\times6(\cos(40^\circ+145^\circ)+i\sin(40^\circ+145^\circ)=42(\cos185^\circ+i\sin185^\circ)=42e^{i185^\circ}
