B- a tra asian between the two figures maps <c to <f

C- Air rotation mapping CB to FD and <B to <D

E- A reflection across CB mapping AC to EF, and <A to <E

Step-by-step explanation:

The rigid motion that verifies the triangles are congruent by SAS is reflection.

In Plane Geometry, a figure which is formed by two rays or lines that shares a common endpoint is called an angle. The two rays are called the sides of an angle, and the common endpoint is called the vertex.

here, we have,

we know that,

The angle of reflection simply means the angle that's formed between the normal ray and the reflected ray. It's the line that's perpendicular to the resulting surface at the point of incidence.

According to the law of reflection, the angle of reflection must be equal to the angle of incidence. Therefore, the rigid motion that verifies the triangles are congruent by SAS is reflection.

Hence, The rigid motion that verifies the triangles are congruent by SAS is reflection.

Answer:

Scale factor = 4

Step-by-step explanation:

Scale factor = [tex]\frac{\text{Dimension of the image}}{\text{Dimension of preimage or original}}[/tex]

Since, S is being dilated with a scale factor to form T,

So, the figure S is the preimage and figure T will be the image,

Length of one side of image T = 8

Length of one side of preimage = 2

Therefore, Scale factor = [tex]\frac{8}{2}[/tex]

                                       = 4

Scale factor by which figure S has been dilated to form figure T is 4.    

Answer:

The answer (in scientific notation) should be 1.8 x 10^2.

Step-by-step explanation:

(2 x 10^6) x (0.00009) = ?

(2 x 1,000,000) x (0.00009) = ?

2,000,000 x (0.00009) = 180

180 as a scientific notation is 1.8 x 10^2.

Answer:

Step-by-step explanation:

It would be helpful if you could share the diagram of the equilateral triangle.

All 3 sides are equal, as are all 3 angles.

The altitude is perpendicular to the base.  The altitude, h, is equal to

h = s*( (√3) / 2, where s is the length of one side of the triangle.

Answer:

a(7) = 21

Step-by-step explanation:

Using the recursive formula and a(1) = 0, a(2) = 1 , then

a(3) = a(2) + 2a(1) = 1 + 2(0) = 1 + 0 = 1

a(4) = a(3) + 2a(2) = 1 + 2(1) = 1 + 2 = 3

a(5) = a(4) + 2a(3) = 3 + 2(1) = 3 + 2 = 5

a(6) = a(5) + 2a(4) = 5 + 2(3) = 5 + 6 = 11

a(7) = a(6) + 2a(5) = 11 + 2(5) = 11 + 10 = 21

Answer:

each side 5

Step-by-step explanation:

with 2 equal internal base angles, we know this is an isosceles triangle

this being isosceles also tells us that the 2 opposite sides are also equal

Therefore: x + 2 = 3x - 4

solving for x

x - 3x = -4 -2

-2x = -6

x = -6 ÷ -2

× = 3

substituting x:

x +2 = 3 + 2 = 5

3x-4 = 9 - 4 = 5

Answer:

1) a≥−2.5

2) n<1.2

3) b≥−0.8

4) false,

5) r≤0.1

6) y≤0.8

Step-by-step explanation:

1) Divide both sides by -3.2.

−3.2a/-3.2 ≤ 8/-3.2

2) Flip the equation

- n+0.8<2

Subtract 0.8 from the sides

n+0.8−0.8<2−0.8

3) Add 4.2 to both sides.

b−4.2+4.2≥−5+4.2

4) inequality cannot be solved

5) Simplify both sides of the inequality.

−r+5.1≥5

Subtract 5.1 from both sides.

−r+5.1−5.1≥5−5.1

−r≥−0.1

Divide both sides by -1.

-r/-1 ≥ -0.1/-1

6) Flip the equation.

−1.8y≥−1.44

Divide both sides by -1.8.

−1.8y/−1.8 ≥ −1.44/−1.8

Answer:

angle A = 47°

angle B= 48°

Step-by-step explanation:

4x+ 4x+ 4+3+85=180°

8x+92=180°

8x= 180-92

8x= 88°

x= 11°

angle A = 4(11)+3= 47°

angle B = 4(11)+4= 48°

Answer:

6/15

Step-by-step explanation:

[tex] \underline{ \underline{ \text{Given}}} : [/tex]

[tex] \underline{ \underline{ \text{To \: find}}} : [/tex]

[tex] \underline {\underline{ \text{ Solution}}} : [/tex]

From equation ( i ) :

-4x - y = 19

-y = 19 + 4x

-y = - ( -19 - 4x )

y = -4x - 19 ------ Equation ( iii )

Substituting the value of y from equation ( iii ) in equation ( ii ) , we get :

[tex] \tt{x - 2y = - 7 }[/tex]

⇾ [tex] \tt{x - 2( - 4x - 19) = - 7}[/tex]

⇾ [tex] \tt{x + 8x + 38 = - 7}[/tex]

⇾ [tex] \tt{9x = - 7 - 38}[/tex]

⇾ [tex] \tt{9x = - 45}[/tex]

⇾ [tex] \tt{x = \frac{ - 45}{9}} [/tex]

⇾ [tex] \boxed{ \tt{x = - 5}}[/tex]

Substituting the value of x in equation ( i ) , we get :

⇾ [tex] \tt{ - 5 - 2y = - 7}[/tex]

⇾ [tex] \tt{ - 2y = - 7 + 5}[/tex]

⇾ [tex] \tt{ - 2y = - 2}[/tex]

⇾ [tex] \tt{y = \frac{ - 2}{ - 2}} [/tex]

⇾ [tex] \boxed{ \tt{y = 1}}[/tex]

The possible solution of the system is ordered pair ( x , y ) = ( -5 , 1 ) .

Answer:

It will cost them $8.32 to run their dishwasher for 52 weeks.

Step-by-step explanation:

With the information provided, you can say that the cost to run the dishwasher is equal to the cost per week for the number of weeks, which would be:

Total cost=$0.16*number of weeks

Since you want to determine the cost to run the dishwasher for 52 weeks, you can replace the number of weeks in the formula to get the answer:

Total cost=$0.16*52

Total cost=$8.32

According to this, the answer is that it will cost them $8.32 to run their dishwasher for 52 weeks.

          Value of constant 'k' = -0.041097

          Equation modeling the exponential decay → [tex]\text{ln}\frac{N}{N_0}=-0.41097t[/tex]

         [tex]\text{ln}\frac{N}{N_0}=-kt[/tex]

         Here, N = Amount remaining after 't' years

                   N₀ = Initial amount of the radioactive element
