Answer:

z = 13 degrees

Step-by-step explanation:

1.) Those two angles add up to 90 degrees, so we can say that 5z - 6 + 2z + 5 = 90

2.) Simplify both sides to get 7z - 1 = 90.

3.) Isolate Variable by adding 1 on both sides to get 7z = 91.

4.) Divide by 7 on both sides to find that z = 13 degrees.

Answer:

z = 13

Step-by-step explanation:

5z - 6 + 2z + 5 = 90

7z - 1 = 90

7z = 91

z = 13

Hope this helps!

What are the horizontal and vertical asymptotes of r(x)=(6x+1)/(16x^2)+1?
Mazyrski [523]
Horiz. asy.:  experiment with letting x grow larger and larger (without bound).  Eventually the given expression will approach some limiting value.

If we continue to increase x in <span>(6x+1)/(16x^2), the fraction will approach 0.  Try it!  

If we continue to increase x in </span><span>(6x+1)/(16x^2) + 1, the expression will approach 0 + 1, or 1.
</span>
Which one did you mean?

Thus, the horiz. asy. would be y=0 or y=1. 

Vertical asy.:  Identify the x-value, if any, at which the denominator of this fraction = 0.

If you meant <span>(6x+1)/(16x^2)                 (without the +1), the fraction is undefined at x=0.  Thus, the vert. asy. is the vertical line x=0.</span>

You start driving north for 12 miles, turn right, and drive east for another 16 miles. How many miles must you travel to return
aleksley [76]

The driver has to drive 20 miles to come back to the starting point directly

Step-by-step explanation:

The driver has driven in the form of two legs on a right-angled triangle where the vertical side (perpendicular) is 12 miles and the horizontal side (base) is 16 miles.

Now as the driver has to return back to the starting point directly, it will form a right-angled triangle making the direct path a hypotenuse

So,

B = 16

P = 12

H = ?

we have to find the hypotenuse

As the triangle is a right angled triangle, we can use the Pythagoras theorem to find the length of hypotenuse So,

H^2 = B^2 + P^2\\H^2 = (16)^2 + (12)^2\\H^2 = 256+144\\H^2 = 400

taking Square root on both sides

\sqrt{H^2} = \sqrt{400}\\H = 20

So

The driver has to drive 20 miles to come back to the starting point directly

Find the slope of the line that passes through the points (5,8) and (9,20)
ankoles [38]

Answer:

Slope = 3

Step-by-step explanation:

the points (5,8) and (9,20)

A point is always written in the form (x, y)

(5,8) and (9,20) is in the form (x1, y1)  and (x2, y2)

Slope =( y2 - y1) / (x2 - x1)

x1=5, x2=9,y1= 8, y2 = 20

Slope = (20 - 8) / (9 - 5)

Slope = 12/4

Slope = 3

A ____ can only display numerical data , while a ______ can display categorical data?
zlopas [31]

Option B

Histogram shows quantitative data. Histograms are used to show the distribution of numerical data. In histogram , the bars are continuous that is adjacent to each other so it is used to represent numerical data.

Bar graphs always shows qualitative data. Bar graph describes the type of categories being compared. There are gaps between the bars. So Bar graphs are used to display categorical data.

A histogram can only display numerical data , while a bar graph can display categorical data
