Answer: 8 (The second option).

Step-by-step explanation:

1. To solve this exercise you draw a line to a point O, this lines will bisect the angle of Z∠60°. Then will obtain two into two right triangles with two angles of 30° at the point Z.

2. The lenght XY will be twice the lengt XO or YO.

3. Let's calclate XO as following:

$sin(30)=\frac{XO}{8}\\XO=4$

4. Then, XY is:

$XY=2XO\\XY=2*4\\XY=8$

You throw three darts in a numbered region of the dart board that has the scores of 2, 5, and 8. How many different sums are pos

givi [52]

Answer:

12 different sums

Step-by-step explanation:

there's three darts and three numbers.

if you use the factorial 3! for both the number of darts and the score numbers and add the two together, you would get twelve :

( 3! = 3*2*1 = 6 ) * 2

6 + 6 = 12

or you could just write out all the combinations like this :

2+2+2

2+2+5

2+5+5

2+5+8

2+8+8

5+5+2

5+5+5

5+5+8

5+8+8

8+8+2

8+8+5

8+8+8

Please help, I don't understand part a or b.

Serggg [28]

Part A
25-9=16
16/2=8
The length of the rope holding the top right corner of the banner to the post is 8 feet long

Part B
13-9-2= 2 for width
25-8=16 16/2=8 for length
Use the Pythagorean Theorem
$a^{2}$ + $b^{2}$ = $c^{2}$
$8^{2}+ 2^{2}= c^{2}$
64+4= $c^{2}$
68= $c^{2}$
$\sqrt{68}= \sqrt{c}$
34=c
The length of the rope from the bottom right corner of the banner to the post is 34 feet

Answer:

10) The equation of a line parallel to $y=-3$ passing through the coordinate (2,6) is $y=6$

11) The equation of a line perpendicular to $y=-3$ passing through the coordinate (2,6) is $x=6$

12) The equation of a line parallel to $x=4$ passing through the coordinate (-2,3) is $x=-2$

13) The equation of a line perpendicular to $x=4$ passing through the coordinate (-2,3) is $y=3$

Step-by-step explanation:

For any line parallel to X-axis the equation we have

$y=a$

where a is the y coordinate.

∴ The equation of a line parallel to $y=-3$ passing through the coordinate (2,6) is $y=6$

For any line parallel to Y-axis the equation we have

$x=b$

Where b is the x coordinate.

∴ The equation of a line parallel to $x=4$ passing through the coordinate (-2,3) is $x=-2$

For any line perpendicular to X-axis is parallel to Y axis therefore the equation we have

$x=b$

∴ The equation of a line perpendicular to $y=-3$ passing through the coordinate (2,6) is $x=6$

For any line perpendicular to Y-axis is parallel to X axis therefore the equation we have

$y=a$

∴ The equation of a line perpendicular to $x=4$ passing through the coordinate (-2,3) is $y=3$
