Amari claims that a rectangle is sometimes a parallelogram but a parallelogram is always a

Mathematics
1 answer:
Maslowich3 years ago
6 0

Answer:

The statement is false.

Step-by-step explanation:

A parallelogram is a figure of four sides, such that opposite sides are parallel

A rectangle is a four-sided figure such that all internal angles are 90°

Here, the statement is:

"A rectangle is sometimes a parallelogram but a parallelogram is always a

rectangle."

Here if we found a parallelogram that is not a rectangle, then that is enough to prove that the statement is false.

The counterexample is a rhombus, which is a parallelogram that has two internal angles smaller than 90° and two internal angles larger than 90°, then this parallelogram is not a rectangle, then the statement is false.

The correct statement would be:

"A parallelogram is sometimes a rectangle, but a rectangle is always a parallelogram"

What is the equation of the line that is perpendicular to the given line and passes through the point (5, 3)
zysi [14]
First, put the equation of the line given<span> into slope-intercept form by solving for y. You get y = 2x +</span>5<span>, so the slope is –2. </span>Perpendicular lines<span> have opposite-reciprocal slopes, so the slope of the </span>line<span> we want to find is 1/2.

A parabola can be drawn given a focus of (-6,3) and a directrix of x = -4. Write
elena55 [62]

Answer:

(y-3)^2=-4(x+5)

Step-by-step explanation:

Given the directrix is vertical, the parabola must have a horizontal axis since it's perpendicular to the directrix.

Therefore, we can use the form (y-k)^2=4p(x-h) where the focus is (h+p,k) and the directrix is x=h-p.

Therefore:

h+p=-6

h-p=-4

2h=-10

h=-5

So:

x=h-p

-4=-5-p

1=-p

-1=p

This means that the parabola opens to the left since p. Remember that p describes the distance between the vertex and focus point.

We can tell that k=3 given the focus point

In conclusion, the equation of the parabola is (y-3)^2=-4(x+5)
