Isabella backed cookies for 3 hours. She spent the same amount of time baking each batch. It took her one eighth an hour to bake
katovenus [111]

I believe it is 24 batches:

because there are 8/8 in one hour, so you multiply that by three. which would give you 24!

Describe the set of points z in the complex plane that satisfy the given equation; |z-2|=Re(z).
OLEGan [10]

Answer:

Parabola with vertex at point (1,0) that goes to the right (see attached diagram).

Step-by-step explanation:

Let the complex number z be

z=x+iy,

then

z-2=x+iy-2=(x-2)+iy\\ \\Re\ (z-2)=x-2\\ \\Im\ (z-2)=y\\ \\|z-2|=\sqrt{Re^2\ (z-2)+Im^2\ (z-2)}=\sqrt{(x-2)^2+y^2}

and

Re\ z=x

Thus,

\sqrt{(x-2)^2+y^2}=x

Square it:

(x-2)^2+y^2=x^2\\ \\x^2-4x+4+y^2=x^2\\ \\-4x+4+y^2=0\\ \\y^2=4x-4\\ \\y^2=4(x-1)

This is the equation of parabola with vertex at point (1,0) that goes to the right.

I'm having a hard time on this problem. Plz help. Will mark brainliest.
Grace [21]

Answer:

<h2>y = 31</h2>

Step-by-step explanation:

We know: opposite angles in a parallelogram have the same measure.

Therefore we have the equation:

x+y=87+y            <em>subtract y from both sides</em>

x=87

We know: the sum of the angle measures in the triangle is 180°.

Therefore we have the equation:

42+(x+y)+20=180          <em>subtitute x = 87</em>

42+87+y+20=180

149+y=180              <em>subtract 149 from both sides</em>

y=31
