Answer:

Statements 1, 3, and 5

1) Two rays joined at the same end point form an angle.

3) A continuous section of the circumference of a circle is a circular arc.

5) A circle is the locus of all points a fixed distance from a given center point.

Step-by-step explanation:

Statement 2 is false because it says that intersecting lines that form right angles are <u>parallel</u> lines.  Actually, intersecting lines that form right angles are perpendicular lines.

Statement 4 is false because it says that lines that never intersect of cross each other are <u>perpendicular</u>.  Actually, lines that never intersect or cross each other are parallel.

Step 1: Choose a point on the line, such as (2, 5).
AlekseyPX

The step of Talia that's incorrect is: C. step 3 because the slope ratio she calculated is incorrect.

<h3>What is the Slope?</h3>

The slope of a line (m) = rise/run = change in y / change in x.

Calculating the slope using two points on the line, (2, 5) and (1, 3), we should have:

Slope (m) = (5 - 3)/(2 - 1)

Slope (m) = (2)/(1)

Slope (m) = 2

This shows that the ratio of the slope calculated by Talia was wrong. The step that is incorrect is: C. Step 3

When drawn in standard position, an angle a has a terminal ray that lies in the second quadrant and whose sine is equal to 9/41.
Semenov [28]

Answer:

\frac{40}{41}

Step-by-step explanation:

We have the angle in standard post has a sine ratio of

\frac{9}{41}

This means the opposite side length of the corresponding right triangle is 9 units and the hypotenuse is 41 units.

Using Pythagoras Theorem, the adjacent side length can be found using:

{x}^{2}  +  {9}^{2}  =  {41}^{2}

This implies that:

{x}^{2}  =  {41}^{2}  -  {9}^{2}

{x}^{2}  =  1600

x =  \pm \sqrt{1600}

x =  \pm40

The cosine ratio is adjacent over hypotenuse.

=  \frac{ \pm40}{41}

Since we are in the second quadrant, the cosine ratio is negative;

=  -  \frac{40}{41}

Use the circle graph to determine how many hours per day Becky spends on each activity.
Oduvanchick [21]
404 error: graph not found

anyway, the graph was not included. since the sleep time was included, I will assume that the circle graph is worth 24 hours

all we need to do is to convert the percentages to fractions and multiply that by 24 to find out how many hours per activity


percent means parts out of 100 so x%=x/100


so we have
School
Eating
Sleep
Homework
Free Time

School=25%
25%=25/100=1/4
1/4 times 24=6
School: 6 hours


Eating=10%
10%=10/100=1/10
1/10 times 24=2.4
Eating: 2.4 hours


Sleep=40%
40%=40/100=4/10=2/5
2/5 times 24=48/5=9.6
Sleep: 9.6 hours


Homework=10%
10%=10/100=1/10
1/10 times 24=2.4
Homework: 2.4 hours


Free Time=15%
15%=15/100=3/30
3/20 times 24=72/20=36/10=3.6
Free Time: 3.6 Hours

Answers:
School: 6 hours
Eating: 2.4 hours
Sleep: 9.6 hours
Homework: 2.4 hours
Free Time: 3.6 Hours

What is the perimeter of a polygon with the vertices at (-2,1),(-2,7),(1,11),(4,7) and (4,1) enter your answer in the box do not
earnstyle [38]

Answer:

  28

Step-by-step explanation:

It helps to plot the points on a graph. It is easy to see that three of the sides are of length 6, and the remaining two are the hypotenuse of a 3-4-5 triangle, hence length 5.

  3×6 +2×5 = 28

The perimeter of this polygon is 28 units.
