Answer:

  both figures are parallelograms

Step-by-step explanation:

The diagonals of a quadrilateral bisect each other if and only if that quadrilateral is a parallelogram. Hence, the left figure is a parallelogram.

The opposite angles of a quadrilateral are congruent if and only if that quadrilateral is a parallelogram. Hence the right figure is a parallelogram.

__

<em>Additional comment</em>

Proofs of these conditions can be offered, but these are the conclusions of the respective proofs. The bisected diagonals form pairs of triangles, provably congruent using SAS. (left figure) The angles total 360°, so any adjacent pair must total 180°, making opposite sides parallel. (right figure)

Which is the graph of the given function?
Schach [20]

ANSWER

The correct choice is A.

EXPLANATION

The given cosine function is:

f(t) = 2 \cos( - 4t)

This function has an amplitude of 2.

Hence it must have range,

-2≤f(t)≤2

It has a period of

\frac{\pi}{2}

Hence the function must complete one cycle on the interval,

[0,½π],

[½π,π],

etc.

The negative sign shows a reflection in the y-axis but since the cosine function is even, the function retraces itself.

The correct choice is A

X⁴+5x²-6=0 solve for x
Snowcat [4.5K]
Let u = x², then we would have u² + 5u - 6 = 0

From here, we can factor it and get us (u-1)(u+6) = 0

So our solution for u is u = -6 or 1.

Now substitute u back to x².

x² = -6 or 1

x = ±√(-6) or ±√1

Since ±√(-6) is not real number, we ignore it.

Which leave us x = ±√1 = <span>±1

So our real solution is x = -1 or 1.</span>

-3x - 10 =5

-3x = 15

x = -5


2x + 6 = -8

2x = -14

x = -7
