Lily graphs segment LM. Then, she reflects the segment across the y-axis. Which statement compares the lengths of the segment LM

Free_Kalibri [48]

Solution

The reflection is a rigid transformation. This does not affect the length of a line segment.

Therefore, the line segments are equal.

Hence, LM = L'M'

Thank you. :)

Which of the following is a solution to the second order differential equation LaTeX: y''=-4y y ″ = − 4 y ? To answer this quest

Paraphin [41]

Answer:

y = sin(2t)
y = cos(2t)

Step-by-step explanation:

In the case of each of the answers listed above, the second derivative is equal to -4 times the function, as required by the differential equation.

For y = 2/3t^3, the second derivative is 4t, not -4y.

For y = e^(2t), the second derivative is 4y, not -4y.

The graph shows the sum of the second derivative and 4y is zero for the answers indicated above, and not zero for the other two proposed answers.

Hello,
The translation t is (x,y)->(x-2,y+3)
So its inverse t^(-1)=-t is (x,y)->(x+2,y-3)

B=-t(B')=(4+2,-8-3)=(6,-11)

Which equation is the inverse of y=7x^2 - 10

4vir4ik [10]

Answer:

Depends on domain of x, could be

-√(y+10)/7; √(y+10)/7 or no solutions

Step-by-step explanation:

You need to solve it for x:

y=7x^2-10

7x^2=y+10

x^2=(y+10)/7

In order for this equation to have an inverse, you need to check the domain of x. There needs to be only one solution for x^2=(y+10)/7 - either positive or negative, depending on the domain.
