Step-by-step explanation:

Answer:

It's a rectangle, but not a rhombus (or square).

Step-by-step explanation:

Let's see the vectors of each next vertex:

[tex]Q - P = (4, 5) - (-5, 2) = (9, 3)\\R - Q = (6, -1) - (4, 5) = (2, -6)\\S - R = (-3, -4) - (6, -1) = (-9, -3)\\P - S = (-5, 2) - (-3, -4) = (-2, 6)\\[/tex]

Firstly, we can notice that it's a parallelogram - because the Q-P side is parallel to the S - R side (if the x:y ratios are the same, the sides are parallel).

A rhombus needs the sides to be of the same length. But the length of a (x, y) vector is [tex]\sqrt{x^2 + y^2}[/tex] and [tex]\sqrt{9^2 + 3^2} > \sqrt{2^2 + (-6)^2}[/tex], we don't even have to compute it exactly. If it's not a rhombus, it's also not a square (every square is a rhombus).

The last thing left is to know if it's a rectangle - for it to be a rectangle, we need to check if the vectors are perpendicular.

We can compute the dot product of the vectors - perpendicular vectors always have a dot product equal to zero. The dot product of two vectors [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex] is equal to [tex]x_1x_2 + y_1y_2[/tex].

[tex](9, 3) \cdot (2, -6) = 9\cdot 2 + 3\cdot(-6) = 18 - 18 = 0[/tex]

So the sides are perpendicular, and as such - the figure is a rectangle.

Answer:

y = 2 yd

Step-by-step explanation:

2y = 2 × 24 /12 = 4 yd

y = 2 yd

second answer dont know sorry because I dont know about trapezoid. I hope someone will help you with that

Answer:

y = -a(x – 2)² – 4

a > 1

Example:

y = -2(x – 2)² – 4

Step-by-step explanation:

y = a(x – h)² + k

____________________

vetex: (h, k)

a: vertical reflection or stretch/compression

__________________________________

If it opens downward, has a vertex of (2, -4) and is narrower than y = x².

Then x² will have a negative coefficient of less than -1 and the input of x will be subtracted by the x value of the vertex which is 2, and the output will be added by the y value of the vertex which is -4.

Therefore y = -a(x – 2)² – 4 where a > 1

Answer:

360°

explanation:

the sum of interior angles of all quadrilaterals (polygons with four sides) is 360°. If you put a pen at any of the four corners and try to draw a line to any other corner, you'll find you can only make two triangles. And since the angle sum of triangles is 180°, 180 times 2 = 360

Answer: If the frequency is 0, it does not repeat.

Step-by-step explanation: A relative frequency table is a chart that shows the popularity or mode of a certain type of data based on the population sampled. When we look at relative frequency, we are looking at the number of times a specific event occurs compared to the total number of events.

Step-by-step explanation:

3rd root of 64=4

3rd root of 125=5

=-4/5 since there's a negative inside

Answer:

I think the answer is C.

Step-by-step explanation:

A triangle inside always has to add up to 180. So of you subtract 78 and 41 from 180 it wil give you 61

Answer: The Answer is 11.

Step-by-step explanation: You line up the least to the greatest so in this case, 8, 6 , 10 , 13 , 14 , and 15, and than you divide that amount by however many numbers there are you are working with. Which would be 6. When all divided and done, it is all equal to 11

Answer:

(32*5)/9

160/9 or approx 17.78

Answer:

$460.92

Step-by-step explanation:

First year monthly salary = $4,718

Second year annual salary = $62,147

Second year monthly salary = Annual salary / 12

= $62,147 / 12

= $5,178.92

How much more per month will you earn your second year?

Amount of increase in second year monthly salary = Second year monthly salary - First year monthly salary

= $5,178.92 - $4,718

= $460.92

Answer:

[tex]\frac{17}{20}[/tex]

Step-by-step explanation:

Answer:

1) -3a + 24b

2) 5x^2 + 2x +1

Step-by-step explanation:

1) (-a + -a+ -a) + (6b + 8b + 10b)

(-3a) + (24b)

-3a + 24b

2) (2x^2 + 3x^2) + (4x - 2x) + (7-6)

(5x^2) + (2x) + ( 1 )

5x^2 + 2x + 1
