Let me know if it doesn't, I can make it right.

The formed triangle is not right angled triangle. The area of circle is 19.64 square units.

The general equation of a straight line is -

[y] = [m]x + [c]

where -

[m] is slope of line which tells the unit rate of change of [y] with respect to [x].

[c] is the y - intercept i.e. the point where the graph cuts the [y] axis.

The area of circle is -

A = πr² = π(d/2)²

A vector is represented by -

A = A[x] i + A[y] j + A[z] k

We have the following problem -

The corners of triangle PQR lie on a circle. PQ = 3i + 4j and PR = -8i + 6j.

|PQ| = 5 units

|PR| = 10

PR + RQ = PQ

RQ = PQ - PR

RQ = 11i - 2j

|RQ| = 11.18

It can be seen that it is not a right angled triangle.

Equation of the diameter of the circle -

y = 4/3x {Assuming it pass through origin}

Diameter length = 5

Radius length = 5/2

Area of circle = 22/7 x 5/2 x 5/2 = 19.64 square units.

Therefore, the formed triangle is not right angled triangle. The area of circle is 19.64 square units.

Answer:

A. 8

Step-by-step explanation:

The angle shown is a 90 degree right angle (shown by the box where the vertex is)

We see that the first angle inside the right angle is 50 degrees, so the other angle must be 40 because the degrees must add up. We can set up an equation here.

[tex]5x=40[/tex]

After dividing both sides by 5, we get x = 8

Answer:

The 4th shape (rectange) is a parallelogram.

Step-by-step explanation:

Rectangle also has opposite sides equal and parallel. The difference between the two is that sides of rectangles form 90° while that of parallelogram don't. So rectangle can be called a parallelogram because they fulfill all the requirement of a parallelogram.

Answer:

120

Step-by-step explanation:

5 factorial

There are total 120 ways to arrange the letters of word "COUNT".

A permutation is a mathematical technique that determines the number of possible arrangements in a set when the order of the arrangements matters.

[tex]nP_{r} =\frac{n!}{(n-r)!}[/tex]

Where,

P is the number of arrangements.

r is the of objects selected.

n is the total numbers of object.

According to the question.

We have a word "COUNT".

Total number of letters in word "COUNT" is 5.

⇒ Total number of objects, n = 5

Since, we have to form different words by using 5 letters of count.

⇒ Total number of objects we have to select, r = 5

Therefore, the total number of ways to arrange the letters of "COUNT" is given by

[tex]5P_{5}=\frac{5!}{(5-5)!}[/tex]

⇒[tex]5P_{5} =\frac{5!}{0!}[/tex]

⇒[tex]5P_{5} =\frac{5!}{1}[/tex]      (because,0! = 1)

⇒[tex]5P_{5} = 5(4)(3)(2) = 120 ways[/tex]

Hence, there are total 120 ways to arrange the letters of word "COUNT".

The area of the composite figure is 70 cm^2

The area of the figure = area of rectangle + area of a triangle

Area of rectangle = length * width
Area of rectangle = 10 * 5
Area of rectangle = 50 square centimeters

Area of triangle = 0.5(5)(8)

Area of triangle = 20 square cm

Area of the figure = 50 + 20
Area of the figure  = 70 square cm

Hence the area of the composite figure is 70 cm^2

A 2-column table that has 3 rows. The first column is labeled x with entries 0, 1, 2. The second column is labeled P x (x) with entries 0. 25, 0. 5, 0. 25.

The probability helps us to know the chances of an event occurring.

[tex]\rm{Probability=\dfrac{Desired\ Outcomes}{Total\ Number\ of\ outcomes\ possible}[/tex]

We know about the probability, therefore, let's find the probability of each of the cases.

When the number of success of the spinner landing on blue is none, therefore, the spinner does not land on the blue color at all.

[tex]\rm{Probability=\dfrac{Desired\ Outcomes}{Total\ Number\ of\ outcomes\ possible}[/tex]

Now, as it is given that there is only one case when the spinner does not land on the blue side(RR) in the set, S = {RR, RB, BR, BB}. therefore,

[tex]\rm{Probability(X=0)=\dfrac{1}{4} = 0.25[/tex]

When the number of success of the spinner landing on blue is just once, therefore, the spinner does land on the blue color only once out of the two spin.

[tex]\rm{Probability=\dfrac{Desired\ Outcomes}{Total\ Number\ of\ outcomes\ possible}[/tex]

Now, as it is given that there are two cases when the spinner does land on the blue side(RB, BR) in the set, S = {RR, RB, BR, BB}. therefore,

[tex]\rm{Probability(X=1)=\dfrac{2}{4} = 0.25[/tex]

When the number of success of the spinner landing on blue is twice, therefore, the spinner does land on the blue color both the times the spinner is spun.

[tex]\rm{Probability=\dfrac{Desired\ Outcomes}{Total\ Number\ of\ outcomes\ possible}[/tex]

Now, as it is given that there is only one case when the spinner does land on the blue side twice(BB) in the set, S = {RR, RB, BR, BB}. therefore,

[tex]\rm{Probability=\dfrac{1}{4} = 0.25[/tex]

Now, if we draw the table of the data and the probability we will get the following table,

x             P(X)

0           0.25

1            0.50

2           0.25

Hence, the table that is correct is table A, which is  A 2-column table that has 3 rows. The first column is labeled x with entries 0, 1, 2. The second column is labeled P x (x) with entries 0. 25, 0. 5, 0. 25.

Answer:

x = 55° (nearest degree)

Step-by-step explanation:

Trig ratios:

[tex]sin(\theta)=\dfrac{O}{H} \ \ \ cos(\theta)=\dfrac{A}{H} \ \ \ tan(\theta)=\dfrac{O}{A} \ \ \[/tex]

where [tex]\theta[/tex] is the angle, O is the side opposite the angle, A is the side adjacent to the angle, and H is the hypotenuse of a right triangle

Given:

[tex]\implies cos(x)=\dfrac{3.3}{5.7}[/tex]

[tex]\implies x=\arccos \dfrac{3.3}{5.7}=54.623459...[/tex]

⇒ x = 55° (nearest degree)

Answer:

54.6° OR 55° rounded up.

Step-by-step explanation:

So it is a fact that 3.3 is adjacent to x. And 5.7 is the hypotenuse.

Now, let's think of SOHCAHTOA: *Always remember that*

SOH: Sin = Opp/Hyp

CAH: Cos = Adj/Hyp

TOA: Tan = Opp/Adj

We will be using CAH since we have the adjacent and the hypotenuse.

Now, you need to plug in the numbers to the correct placement, in this case, it will look like this:

Cos(x) = 3.3/5.7

*If I were you, I'd use a Cosine calculator online or just your handy-dandy standard calculator because you can't just plug in 3.3/5.7 like that and expect to get the answer.*

*In order to find the cosine on a regular calculator, you must press the inverse button, followed by the cos button. Or just use the "arccos" button if it's on there*

Clockwise from the top left, the angles are ∠1, ∠2, ∠3, ∠4, ∠5, ∠6, ∠7, ∠8 are 96°, 84°, 96°, 84°, 56°, 124°, 56°, 124° respectively. Then the correct option is A.

Angle is the space between the line or the surface that meets.  And the angle is measured in degree. For complete 1 rotation, the angle is 360 degrees.

Supplementary angle - Two angles are said to be supplementary angles if their sum is 180 degrees.

Vertically opposite angle - When two lines intersect, then their opposite angles are equal.

In the diagram, the measure of angle ∠8 is 124°, and the measure of angle ∠2 is 84°.

Angle ∠1 and ∠2 are supplement angles.

∠1 + ∠2 = 180°

∠1 + 84° = 180°

        ∠1 = 96°

Similarly, angles ∠7 and ∠8 are supplement angles.

∠7 + ∠8 = 180°

∠7 + 124° = 180°

          ∠7 = 56°

By the property of the opposite angles, we have

∠1 = ∠3 = 96°

∠2 = ∠4 = 84°

∠5 = ∠7 = 56°

∠6 = ∠8 = 124°

Clockwise from the top left, the angles are ∠1, ∠2, ∠3, ∠4, ∠5, ∠6, ∠7, ∠8 are 96°, 84°, 96°, 84°, 56°, 124°, 56°, 124° respectively.

Then the correct option is A.
