<h2>Answer:</h2>

The statement that is true about the point and planes is:

The line that can be drawn through points D and E is contained in plane γ.

<h2>Step-by-step explanation:</h2>

We know that if two points lie in a plane that the line connecting those two points will also lie in the same plane and hence all the points above that line are in the same plane.

and if two points are in different plane which are perpendicular than the line connecting those two points lie outside both the planes.

Hence, from the above points we have:

The line that can be drawn through points D and E is contained in plane γ.

How many real solutions exist for this system of equations?

Rom4ik [11]

Answer:

One

Step-by-step explanation:

Set each equations equal to each other

${x}^{2} + 4 = 4x$

${x}^{2} - 4x + 4$

Find the discrimant.

${ - 4 {}^{2} - 4(1)(4) } = 0$

This means there is one real solution. Since the discramnt equal 0.

For the function y = -2+5sin(pi/12(x-2)), what is the maximum value?

myrzilka [38]

To get the function y = <span>-2+5sin(pi/12(x-2)), the maximum value can be determined by differentiating the function and equating it to zero. The value of x will give the maximum value of the function.
dy/dx = 5 cos (pi/12 (x-2)) (pi/12)
dy/dx = 5 pi/12 cos(pi/12 (x-2))

Equate to zero</span>:
<span>5 pi/12 cos(pi/12 (x-2)) =0
pi/12 (x-2) = 3pi/2
x = 8

Substituting,
y= -2 + 5sin( pi/12 (8-2)
y = -1.86

Find AE in the parallelogram, if BD = 12, and AC = 18

Liono4ka [1.6K]

See the picture in the attached figure

we know that

There are six important properties of parallelograms to know:

<span>1) Opposite sides are congruent (AB = DC).
2) Opposite angels are congruent (D = B).
3) Consecutive angles are supplementary (A + D = 180°).
4) If one angle is right, then all angles are right.
5) The diagonals of a parallelogram bisect each other.
<span>6) Each diagonal of a parallelogram separates it into two congruent triangles.

so
if t</span></span>he diagonals of a parallelogram bisect each other
then
AE=EC
AC=AE+EC------> AC=2*AE----> AE=AC/2----> AE=18/2----> AE=9 units

the answer is
AE=9 units
