Line / is shown on the graph below. If another line is drawn, perpendicular to line I, what must be its slope?

Mathematics
1 answer:
juin [17]2 years ago
7 0

Answer:

Undefined

Step-by-step explanation:

The slope on the graph is horizontal so there's no slope and the answer is just y = 3

For a line to be perpendicular to a horizontal line, it is going to be a vertical line.

All vertical lines have an undefined slope.

Firstly, we have to find the mean. The mean is simply the average of the numbers, which we find by adding each number in the sequence and then dividing that result by the total amount of numbers.

<em>13.3 + 14.3 + 15.3 + 16.3 + 17.3 = 76.5</em>

<em>76.5 / 5 = 15.3

</em>Okay, so our average is 15.3.
<em>
Now, </em>we have to subtract the mean from each number and then square the result.

<em>(13.3 - 15.3)^2 = 4</em>
<em>(14.3 - 15.3)^2 = 1</em>
<em>(15.3 - 15.3)^2 = 0</em>
<em>(16.3 - 15.3)^2 = 1</em>
<em>(17.3 - 15.3)^2 = 4

</em>Now we have to find the mean of those numbers!
<em>
4 + 1 + 0 + 1 + 4 = 10

10 / 2 = 2

</em>Finally, we take the square root of that number and we have our standard deviation. =)<em>

The grassy area of a playground has a side length of x and a side of width of x + 3 what is the area of the playground?
Kipish [7]

Answer:

A

Step-by-step explanation:

We assume this playground is a rectangle. The area of a rectangle is of the form: A = lw, where l is the length and w is the width.

Here, the length is l = x and the width is w = x + 3. So, plug these in:

A = lw

A = x(x + 3)

Expand this out:

A = x² + 3x

The answer is thus A.

Number 9 !!!! please answer !!!! explain how u got the answer and the answer of cpurse
storchak [24]

answer:

90 degrees + 28 degrees= 118 degrees

180-118= Z is 62 degrees

13y-1 = 24                                     2x-7 = 39

+1           +1                                          +7     +7

13y = 25                                          2x = 46

/13      /13                                           /2     /2

y = 1.92                                            X = 23

Someone help find surface area of a right rectangular prism
Bond [772]

Answer:

51 square units

Step-by-step explanation:

First you act like each side is it’s separate rectangle.

Then you would multiply 2 and 4 to get 8, the area of one of the sides. Then you would multiply 2 and 2.5 to get 5, the area of another side. Then 2.5 times 5 to get 12.5, the last side. Now sense every side has a side the same size of itself you would take each answer and multiply it by to to get 8x2=16, 5x2=10, and 12.5x2= 25. You would add together 16, 10, and 25 to get 51 square units, the surface area.
