Find the missing term. If y = 1 + i, then y3 − 3y2 + (-3y) (-3y + 1) (3y) (3i ) − 1 = -i .

1 answer:

7 0

Filling in y=1+i without the missing term yields -3-4i.

-3-4i = -3(1+i) - i

So we have to add 3(1+i) to get to -i.

3(1+i) = 3y, so 3y is the answer.

A recipe will make 10 pancakes that are 8 inches in diameter. If you decide to

pashok25 [27]

10 pancakes produces 8 inches in diameter.
The area of 1 pancake is
Area = pi * r^2
Area = pi * 4^2
Area = 50.27 in^2
Then multiply it by 10
Total area = 502.65 in^2

A smaller pancake
Area = pi * r^2
Area = pi * 2^2
<span>Area = 12.56 in^2

Divide 502.65 by 12.56
= 502.65 / 12.65
= 39.74

So there are 39 pancakes.

Identify the surface with the given vector equation. r(u, v) = 2 sin(u) i + 5 cos(u) j + v k, 0 ≤ v ≤ 5 plane hyperbolic parabol

olchik [2.2K]

Note that this just produces three parametric equations:

$x(u) = 2 \sin(u)$
$y(u) = 5 \cos(u)$
$z(v) = v$

In the $x-y$ plane, this is just he parametric equation for an ellipse (as a function of u). The z is simply a linear function.

The surface is then an ellipse extruded along the z-axis. We get a elliptic cylinder.
