Segment XY is transformed using rigid transformation to get segment X′Y′ as shown in the graph. Segment X Y with endpoints X (1,6), Y (5, 0), & segment X prime Y prime with endpoints X prime (0, negative 6), Y prime (negative 4, 0).

Which series of transformations correctly maps XY¯¯¯¯¯¯¯¯ to X′Y′¯¯¯¯¯¯¯¯¯¯¯¯?
a reflection across the x-axis and a rotation 90∘ clockwise about the origin
a rotation 180∘ clockwise about the origin and a translation right 1 unit
a rotation 180∘ clockwise about the origin and a translation left 1 unit
a reflection across the y-axis and a rotation 90∘ clockwise about the origin

huh? im pretty sure it is in 199

step-by-step explanation:

step-by-step explanation:

the answer is $42.96

step-by-step explanation:

the solution of the equation is 2.23 ⇒ answer b

step-by-step explanation:

* lets revise the meaning of exponential function

- the form of the exponential function is y = ab^x, where a ≠ 0, b > 0 ,  

  b ≠ 1, and x is any real number

- it has a constant base b

- it has a variable exponent x

- to solve an exponential equation, take the log or ln of both sides,  

  and solve for the variable

* lets solve the problem

∵

- the base is 7 and the exponent is x

- insert ㏑ in both sides

∴

- use the rule

∴ x ㏑(7) = ㏑(77)

- to find x divide both sides by ㏑(7)

∴

* the solution of the equation is 2.23 to the nearest 2 decimal places
