A transformation maps a preimage triangle to the image triangle shown in the coordinate plane below.
If the preimage triangle is reflected over the y-axis to get the image triangle, what are the coordinates of the vertices of
the preimage triangle?
Answers
The coordinates of the vertices of the preimage triangle = (4, 1), (6,1) and (6, -6).
Given the figure of the image triangle.
The coordinates of the image triangle are (-4, 1) , (-6,1) and (-6, -6).
We are asked to find the coordinates of the preimage triangle.
The preimage triangle was reflected over the y-axis .
The image triangle is lying on the 2nd and 3rd quadrants.
So the preimage triangle will lie on the 1st and 4th quadrants.
Then the coordinate (-4,1) will be the image of (4,1).
(-6, 1) will be the image of (6,1) and (-6,-6) will be the image of (6,-6).
Hence the coordinates of the vertices of the preimage triangle = (4, 1), (6,1) and (6, -6).

the sides of a triangle are of lengths 13, 14, and 15. the altitudes of the triangle meet at point h
Answers
The ratio HD:HA is 5/11 when the sides of a triangle are of lengths 13, 14, and 15.
What do you mean by heron's formula?When the lengths of all three sides are known, the geometry formula Heron's formula, which bears Hero of Alexandria's name, determines the area of a triangle. There is no need to first determine the angles or other distances in the triangle, unlike other triangle area formulas. Heron of Alexandria is credited with developing the Heron's formula, which determines the area of a triangle in terms of the lengths of its sides. If the side lengths are represented by the symbols a, b, and c: Area is equal to the square root of (a + b + c)/2, where s is half the perimeter.
By Heron's Formula, the area of this triangle is 84 Thus the height perpendicular to AB has a length of 11.2, and by the Pythagorean Theorem, AE and EB have lengths 6.6 and 8.4, respectively. These lengths tell us that C is at.
The slope of BC is (0-11.2)/(15-6.6)=-4/3, and the slope of AD is 3/4 by taking the negative reciprocal of -4/3. Therefore, the equation of line AD can best be represented by y=(3/4) x.
We next find the intersection of CE and AD . We automatically know the x -value; it is just 6.6 because CE is a straight line hitting (6.6,0). Therefore, the y -value is at (3/4)* 6.6=4.95. Therefore, the intersection between CE and AD is at (6.6,4.95) .
We also need to find the intersection between BC and AD . To do that, we know that the line of AD is represented as y=3/4x, and the slope of line BC is -4/3. We just need to find line BC 's y-intercept. So far, we have y=-4/3x+b, where b is a real y-intercept. We know that B is located at (15,0), so we plug that into the equation and yield b=20. Therefore, the intersection between the two lines is
(3/4)x=-(4/3)x+20
⇒9x=-16x+240
⇒25x=240
⇒x=9.6
Now y=(3/4)*x=(3/4)*9.6=7.2
⇒y=7.2
After that, we use the distance formula: HA has a length of
√(6.6-0)²+(4.95-0)²=√(1089/25)+(9801/400)
=√(1089*16+9801)/400
=√27225/400=√1089/16=33/4=8.25
and HD has a length of
√(9.6-6.6)²+(7.2-4.95)²=√(3)²+(36/5-99/20)²
=√(9)+(81/16)
=√225/16=15/4=3.75
So the ratio os HD:HA is
⇒3.75/8.25=15/33=5/11

What is Pythagorean theorem?The Pythagorean theorem, sometimes known as Pythagoras' theorem, is a fundamental relationship in Euclidean geometry between the three sides of a right triangle. It states that perhaps the area of something like the square on which side would be the hypotenuse is equivalent to the sum of something like the areas of the squares on each of the other two sides.
What Is the Pythagorean Theorem Formula Good For?The Pythagorean theorem is only valid for right-angled triangles. When any two numbers are known, we can use Pythagoras' theorem to compute the unknown sides of something like the triangle. Other real-world applications of Pythagoras' theorem include engineering and architecture.
According to the given information:The first ship travels north at 20 kilometers an hour, while the second travels west at 15 miles per hour.
equation for the given distance between boats after t hours:
Using Pythagoras formula:C² = a² + b²
C = √(a² + b²)
a = dist. traveled in t hrs. of the 1st ship.
b = dist. traveled in t hrs. by 2nd ship.
c = dist. between the two ships after t hrs. (d)
Using formula Distance = speed * time (t)
d = √((20t)²+(15t)²)
d = √(625t²)
d = 25t is the distance between the ships after t hrs.

KL=3x + 7, and
JK = 8x + 8,
Find KL.

Answers
Answer:
KL = 10
Step-by-step explanation:
Given:
[tex]JL=26[/tex]
[tex]KL=3x+7[/tex]
[tex]JK=8x+8[/tex]
From inspection of the given diagram:
[tex]JK+KL=JL[/tex]
Substitute the given values into the found equation and solve for x:
[tex]\implies 8x+8+3x+7=26[/tex]
[tex]\implies 11x+15=26[/tex]
[tex]\implies 11x+15-15=26-15[/tex]
[tex]\implies 11x=11[/tex]
[tex]\implies \dfrac{11x}{11}=\dfrac{11}{11}[/tex]
[tex]\implies x=1[/tex]
Substitute the found value of x into the expression for KL:
[tex]\implies KL=3(1)+7[/tex]
[tex]\implies KL=3+7[/tex]
[tex]\implies KL=10[/tex]
Formula we use,
→ JK + KL = JL
Now the value of x will be,
→ (8x + 8) + (3x + 7) = 26
→ 11x + 15 = 26
→ 11x = 26 - 15
→ x = 11/11
→ [ x = 1 ]
Then the value of KL will be,
→ 3x + 7
→ (3 × 1) + 7
→ 3 + 7 = 10
Hence, the value of KL is 10.

Answer: 5/6
Step-by-step explanation:
Probability is the likelihood or chance that an event will occur.
It will land on 1, Prob (land on 1) = 1/6
It will not land on 1, the probability will be given as:
Prob (not land on a 1) = 1 - 1/6
Prob (not land on a 1) = 5/6

Step-by-step explanation:
[tex]\boxed{\begin{minipage}{4.3 cm}\underline{Circumference of a circle}\\\\ $C=\pi d$\\\\where $d$ is the diameter\end{minipage}}[/tex]
From inspection of the given diagram:
Diameter of the larger circle = 5 + 14 + 4 = 24 cmDiameter of the smaller circle = 14 cmThe perimeter of a two-dimensional shape is the distance all the way around the outside.
Therefore, the perimeter of the given shaded region is the sum of half the circumference of the larger circle, half the circumference of the smaller circle, and the two 5 cm ends.
[tex]\begin{aligned}\sf \implies Perimeter & = \sf \dfrac{1}{2} \pi (24) + \dfrac{1}{2} \pi (14) + 5 + 5\\& = \sf \dfrac{1}{2}(3.14)(24) + \dfrac{1}{2}(3.14)(14) +10\\& =\sf 37.68+ 21.98+10\\& =\sf 69.66\:\:cm\end{aligned}[/tex]
Therefore, the perimeter is 69.66 cm.
The perimeter of the shaded region is 12.56 times the radius of one of the semicircles.
To find the perimeter of the shaded region, we need to find the total length of all the boundaries.
The shaded region consists of two semicircles, so we can start by finding the circumference of each semicircle.
The formula for the circumference of a circle is C = 2πr.
Since we have two semicircles, we need to find the radius for each and then add the two circumferences together to get the total perimeter.
Let's say the radius of each semicircle is r.
Using the given value of π as 3.14,
the circumference of one semicircle is 2 * 3.14 * r = 6.28r.
Therefore, the total perimeter is 6.28r + 6.28r = 12.56r.
So, the perimeter of the shaded region is 12.56 times the radius of one of the semicircles.
