Answer:

Step-by-step explanation:

We can prove ∠Q ≅ ∠U, by showing the triangles congruent.

Given that a pair of triangles, ΔSQR and ΔTUR, connected at the point R, in which QR ≅ RU, SR ≅ RT.

We need to prove that ∠Q ≅ ∠U,

So, to prove the same we will use the concept of congruent triangles, the type of triangles in their corresponding parts are congruent, by showing the triangles congruent we can prove ∠Q ≅ ∠U.

1) QR ≅ RU, SR ≅ RT (given)

2) ∠QRS ≅ ∠TRQ (vertical angles are congruent)

3) ΔSQR and ΔTUR (by SAS congruency rule)

4) ∠Q ≅ ∠U (CPCTC)

Hence proved.

Answer:

4 units

Step-by-step explanation:

(0, 0 ) and (4, 0 )

since the y- coordinates are equal  then the distance between the points is the difference of the x- coordinates, that is

| 4 - 0 | = | 4 | = 4 or

| 0 - 4 | = | - 4 | = | 4 | = 4

Answer:

t=2s

Step-by-step explanation:

This is saying that the turtles age is two times the stingrays age because no matter how old the stingray is, the turtle is 2 times older.

Answer: t=s+2

Step-by-step explanation:

The sea turtle is 2 years older than the stingray.

Sea turtle's age = 2 years + stingray's age.

t = s+2

Step-by-step explanation:-

The given line is 3x + 4y - 12 = 0

=> 4y = -3x + 12 ....(i)

=> y = -3x/4 + 3,

therefore, the slope of the line (i) = -3/4.

From P(-1,-2), draw PN perpendicular to the given line. (see attachment)

As we know,, m2 = -1/m1

So, the slope of the line PN = 4/3

the equation of the line through P(-1,-2) and having a slope 4/3 is :-

= > y - (-2) = 4/3 * (x - (-1))

= > 3y + 6 = 4x + 4

= > 4x - 3y - 2 = 0....(ii)

which is the required equation of the perpendicular from P to the given line. To find the coordinates of N (the foot of perpendicular), solve (i) and (ii) simultaneously. Multiplying (i) by 3 and

(ii) by 4, and on adding, we get

= > 25x - 44 = 0

= > x = 44/25

Multiplying (i) by 4 and (ii) by 3, and on subtracting, we get :-

= > 25y - 42 = 0

= > y = 42/25

Hence, the coordinates of the foot of the perpendicular are (44/25 , 42/25)

(44/25 , 42/25)

these are the points

Answer:

Step-by-step explanation:

17. Domain is all real numbers because the equation has a y-value for all x-values as far as we can see with the information given.

18. Range is 3< y <8, because the equation only has values for x where y is between those numbers.

19. Range is 3> y >-∞ (negative infinity) because the parabola's vertex has a y-coordinate of 3 and the parabola goes on forever in the negative direction (as seen by the arrows).

20. Domain is -∞ < x < 4 because the parabola's vertex has an x-coordinate of 4 and goes on forever in the negative x direction.

Answer:

0.267 square units (or 8/30 square units)

Step-by-step explanation:

width = 3 rectangles

length = 10 rectangles (left to right)

area = width * length = 30 rectangles

the striped rectangle is made up of 8 regular rectangles

thus, (area we want) / (total area) = 8/30 of the whole ≈ 0.267 of the whole

the whole is 1 square unit, so 0.267 of 1 square unit =  0.267 * 1 square unit = 0.267 square units

Answer:

x = 55

Step-by-step explanation:

the inscribed angle x is half the measure of its intercepted arc, that is

x = [tex]\frac{1}{2}[/tex] × 110 = 55

Answer:

y = -3, x = 5

Step-by-step explanation:

In the first equation, x = 2 - y, x is on one side. So we can try to isolate the variable x in the second equation by adding 2y + 11 on both sides to get:

x = 2y + 11

So now we have equations x = 2 - y and x = 2y + 11. Therefore 2 - y = 2y + 11.  Now we isolate variable y by adding y on both sides and subtracting 11 on both sides to get -9 = 3y. Divide by 3 on both sides to get y = -3.

Let's substitute that into x = 2 - y. Since y = -3, we now have x = 2 - (-3) = 5.

Step-by-step explanation:

a)

rate of change is rise over run: change in y / change in x.

function 1:

- i will use first 2 pairs of data

- change in y: 5 - 3 = 2

- change in x: -2 - (-1) = -1

-rate of change = 2/-1 = -2

function 2:

- same idea, but find two points on the graph!

- (0,4) and (-1,0) for example! pick easy points

- change in y is 4. chabge in x is 1

- rate of change is 4

b)

function b has greatest rate of change. 4 > -2

Answer:

d ≤ -3

Step-by-step explanation:

Given that:

−13d + 6 ≤ 45

Solve:

Subtracting 6 from both sides

−13d + 6 ≤ 45

       -6    -6

-----------------------

−13d ≤  39

Multiply both sides by -1 which reverse the inequality

13d ≤ -39

Now divide both sides by 13

13d/13 ≤ -39/13

d ≤ -3

Thus the Answer is:

d ≤ -3

Considerando la estatura de Fernando, la longitud de su sombra y la distancia con respecto a la lámpara, la altura de la lámpara encendida es de 7.20 metros. (Opción correcta: A)

En la geometría Euclídea el concepto de proporcionalidad está asociado con el concepto de semejanza entre triángulos. Esta relación subyace en el hecho que si tenemos garantizado que existen un número suficiente y conocido de valores y características comunes entre los dos triángulos, entonces podemos determinar los valores faltantes.

En esta pregunta tenemos dos triángulos rectángulos que son semejantes, por ende, proporcionales. Por la definición de proporcionalidad derivamos la siguiente expresión para la altura de la lámpara:

h/H = x/X     (1)

DURING A HOME #KACHA BADAM JAKE KAACHA BADAM HWADNA

Step-by-step explanation:

There are 3 cubes in the solid's length, 2 in its width, and 3 in its height. Therefore, the number of cubes = length * width * height = 3*2*3 = 18

The volume of a small cube , for a length l, is l³. The length is (1/3)m, so the volume is (1/3)³ = 1/27 m³

volume of solid = number of cubes * area of each cube = 1/27 * 18 = 18/27 m³. This is because we have to figure out the volume of 18 cubes together, and we can just add each cube to the volume 18 times for our answer

Answer:

  69.6 ft

Step-by-step explanation:

The arc length can be found as a fraction of the circumference. That fraction is the ratio of the central angle measure to the measure for the whole circle.

__

Central angle of remaining arc:

  360° -150° = 210°

Fraction of full circumference:

  210°/360° = 7/12

The circumference of the circle is ...

  C = 2πr = 2π(19 ft) = 38π ft.

Then the length of the remaining arc is ...

  (7/12)(38π) ft ≈ 69.6 ft
