The following set of coordinates most specifically represents which figure? (−5, 6), (−1, 8), (3, 6), (−1, 4) (6 points) Paralle

Vladimir [108]

Answer:

Rhombus

Step-by-step explanation:

The given points are A(−5, 6), B(−1, 8), C(3, 6), D(−1, 4).

We use the distance formula to find the length of AB.

$|AB|=\sqrt{(-1--5)^2+(8-6)^2}$

$|AB|=\sqrt{16+4}$

$|AB|=\sqrt{20}$

The length of AD is

$|AD|=\sqrt{(-1--5)^2+(6-4)^2}$

$|AD|=\sqrt{16+4}$

$|AD|=\sqrt{20}$

The length of BC is:

$|BC|=\sqrt{(-1-3)^2+(8-6)^2}$

$|BC|=\sqrt{16+4}$

$|BC|=\sqrt{20}$

The length of CD is

$|CD|=\sqrt{(-1-3)^2+(6-4)^2}$

$|CD|=\sqrt{16+4}$

$|CD|=\sqrt{20}$

Since all sides are congruent the quadrilateral could be a rhombus or a square.

Slope of AB $=\frac{8-6}{-1--5}=\frac{1}{2}$

Slope of BC $=\frac{8-6}{-1-3}=-\frac{1}{2}$

Since the slopes of the adjacent sides are not negative reciprocals of each other, the quadrilateral cannot be a square. It is a rhombus

Kamal sells 240 ice creams for a total of £640

Free_Kalibri [48]

Answer:

2.10

Step-by-step explanation:

# of large ice creams: 240/3 = 80

# of small ice creams: 240 - 80 = 160

Total large ice cream cost: 80*3.8 = 304

Total small ice cream cost: 640 - 304 = 336

Cost of one small ice cream: 336/160 = 2.1

Suppose that the functions p and q are defined as follows.<br> HELP PLEASE

nadezda [96]

Answer:

25, 9

Step-by-step explanation:

(p . q)(8) means do q first to 8 then do p to that, which is the same as writing p(q(8)). Then just plug the numbers in.

q(8)=√8+8=√16=4

p(4)=4^2+9=16+9=25

The second one is the opposite order but same reasoning.

p(8)=8^2+9=64+9=73

q(73)=√73+8=√81=9

Answer the question in the picture

aleksklad [387]

Answer:

The y-intercept of Function A is <u>GREATER</u> than the y-intercept of Function B

Step-by-step explanation:

First we need to find the y-intercept for Function A and B

To find the y-intercept we need to get the graph into slope-intercept form

(Which is y=mx+b with "m" being slope and "b" being y-intercept)

First we need to find the slope or "m":

The formula for slope is m= y2-y1/x2-x1

We can use the points from Function A as our x1, x2, y1, and y2

I will use (1,9) and (2,13) as they are the easiest

Since (1,9) is more above the graph it is the x1 and y1

With (2,13) being x2 and y2

13-9/2-1

Which is 4

Thus the slope is 4

The equation now looks like this:

y=4x+b

Now we need to find the y-intercept, and to do that we will need to substitute one of the points (their x and y values)

Using (1,9) we can substitute the x and y with 1 and 9

9=4+b

Subtract 4 on both sides:

5=b

Thus the y-intercept is 5

Now that we know the y-intercept of Function A we will need to find the y-intercept for Function B

To find the y-intercept we just need to find the number ON THE Y-AXIS (And with x=0) that the line intercepts to.

From the graph we can see that 2 is on the y-axis that the line intercepts, thus 2 is the y-intercept

Since 5 is greater than 5 The y-intercept of Function A is greater than the y-intercept of Function B

Hope this helps!
