Find the distance between K(9, 2) and L(-3, 9) to the nearest tenth

Answers

Answer 1

Answer:

≈ 13.9

Step-by-step explanation:

Calculate the distance d using the distance formula

d = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]

with (x₁, y₁ ) = K(9, 2) and (x₂, y₂ ) = L(- 3, 9)

d = [tex]\sqrt{(-3-9)^2+(9-2)^2}[/tex]

   = [tex]\sqrt{(-12)^2+7^2}[/tex]

   = [tex]\sqrt{144+49}[/tex]

   = [tex]\sqrt{193}[/tex]

   ≈ 13.9 ( to the nearest tenth )

Answer 2
Answer:

d=√(193)

Step-by-step explanation:

d=√((x_2-x_1)²+(y_2-y_1)²)

Points: (9, 2) & (-3, 9)

d=√((-3 - 9)²+(9 - 2)²)

d=√((-12)²+(7)²)

d=√(144)+(49)

d=√(193)

i think the answer would be 1/6 hope this helps!

Answer:

1/12

Step-by-step explanation:

Probability = # of events / # of possible outcomes.

We want to find the probability of flipping a tails and then rolling a two.

When flipping a coin there are only two possible outcomes, getting a head or a tails.

So the probability of flipping a tails would be 1/2.

When rolling a dice there are 6 possible outcomes.

So the probability of rolling a two is 1/6

We then multiply the two probabilities to get our answer.

[tex]\frac{1}{2} =\frac{1}{6} =\frac{1*1}{2*6} =\frac{1}{12}[/tex]

The answer is 1/12

X, Y, and Z are collinear and Y is between X and Z. If XY = 3x – 1, YZ = 5, and XZ = 5x – 8,

what is the value of x?

a. 6
b. 4
c. 10
d. 8

Answers

Answer:

6

Step-by-step explanation:

XY = 3x – 1, YZ = 5, and XZ = 5x – 8,

We know that XY + YZ = XZ, so

3x - 1 + 5 = 5x - 8

3x + 4 = 5x - 8

3x + 12 = 5x

12 = 2x

6 = x

The value of x from the given line segment XZ is 6. Therefore, the correct answer is option A.

Given that, X, Y, and Z are collinear and Y is between X and Z.

Collinear points are those that are on the same straight line or in the same plane. In Euclidean geometry, two or more points on a line that are close to or far from each other are said to be collinear.

So, here [tex]XZ=XY+YZ[/tex]

[tex]5x-8=3x-1+5[/tex]

[tex]5x-8=3x+4[/tex]

[tex]5x-3x=4+8[/tex]

[tex]2x=12[/tex]

[tex]x=6[/tex]

Therefore, the correct answer is option A.

Answers

The area of a sector is 339.336 cm²

The area of a sector is defined to be as the region of space bounded by a boundary from the center of the circle.

It can be determined by using the formula:

[tex]\mathbf{A = \dfrac{\theta }{360}\times \pi r^2 }[/tex]

Given that;

Radius r = 18 cmAngle θ =  120°

Then. the area of the sector can be calculated as:

Not for 5 points. Maybe for 10 points, but not 5.
Angles in a triangle add up to 180.
Angles on a straight line also add up to 180.

Using this knowledge, you can find angle OLW which lies on a straight line:

180 – (2x–48)

(Where 2x – 48 is the other angle which lies on the straight line)

180 – 2x + 48

228 – 2x

So angle OLW is 228 – 2x.


Now that you know all the angles in the triangle, add the sum of all the angles and make it equal to 180 to find the value of x (you make it equal to 180 because all angles in a triangle add up to 180).

180 = 228 – 2x + x + 32

180 = 260 – x

180 + x = 260

x = 260 – 180

x = 80

So the value of x is 80.


Substitute x = 80 into the expressions for the angles to find the sizes of the angles.

Angle FOW = x
Angle FOW = 80

Angle FLW = 2x – 48
Angle FLW = 2(80) – 48
Angle FLW = 160 – 48
Angle FLW = 112

Angle OLW = 180 – 80 – 32
Angle OLW = 68

Answers

Answer:

4√2 cm

Step-by-step explanation:

ABCD is a square.

Each side measures 8 cm.

So,

AB = BC = CD = AD = 8 cm

P, Q, R, and S are mid - points of ABCD.

P is the mid - point of AB.

So,

AP = PB

AP + PB = AB

AP + AP = AB

2AP = 8

AP = 8 / 2

AP = 4 cm

S id the mid - point of AD.

So,

DS = SA

DS + SA = AD

SA + SA = AD

2SA = 8

SA = 8 / 2

SA = 4 cm

Property of a square : The angle between two sides is 90°.

So,

The angle between side SA and AP is 90°.

So,

SA, AP and SP forms a right angled triangles.

By Pythagoras theorem,

( SP)² = ( SA )² + ( AP )²

( SP )² = 4² + 4²

= 16 + 16

( SP )² = 32

SP = √32

SP = 4√2 cm

Since PQRS is also a square.

In square, all sides are equal.

So,

PQ = QR = RS = SP

Since SP = 4√2 cm

Hence,

PQ = 4√2 cm

Therefore,

the length of PQ is 4√2 cm.

Answer: 5.7

Step-by-step explanation:

Midpoint means the middle of line. So to find the middle of the line I just need to divide the line by 2.

So the midpoint of AB is:

8/2=4 = BP

Since Q is also a midpoint so BQ is equal to 4.

We know BP=BQ=4. Looking at the diagram we can tell PBQ is a triangle.

The hypotenuse of the triangle is PQ.

Pythagoras's theorem helps us to find the hypotenuse. So we just plug in the values to find PQ.

P's Theorem : a²+b²=c²

basically in the case of this question it means:

(BP)²+(BQ)²=(PQ)²

now we just subsiture the values and solve for PQ:

4²+4²=(PQ)²

16+16=(PQ)²

32=(PQ)²

PQ=5.65...

= 5.7(rounded to one decimal place)
