−3(10−(3−8)+4−2²-−3(4−9))

=−3(10−(−5)+4−2²-−3(4−9))

=−3(15+4−2²-−3(4−9))

=−3(19−2²-−3(4−9))

=−3(19−4−3(4−9))

=−3(15−3(4−9))

=−3(15−(3)(−5))

=−3(15−(−15))

=(−3)(30)

=−90

Which composition of transformations maps figure EFGH to figure E"F"G"H"?

Lady bird [3.3K]

The transformations would map EFGH to ${\text{E''F''G''H''}}$ is a reflection across line k followed by a translation down. Option (a) is correct.

Further explanation:

Given:

The compositions of transformations from EFGH to ${\text{E''F''G''H''}}$ are as follows,

(a). A reflection across line k followed by a translation down.

(b). A translation down followed by a reflection across line k.

(c). A ${180^ \circ }$ rotation about point G followed by a translation to the right.

(d). A translation to the right followed by a ${180^ \circ }$ rotation about point G.

Explanation:

Translation can be defined as to move the function to a certain displacement. If the points of a line or any objects are moved in the same direction it is a translation.

Rotation is defined as a movement around its own axis. A circular movement is a rotation.

Composition of the functions is <br> ____ commutative.

Aleksandr [31]

Answer:

See below.

Step-by-step explanation:

Composition of the functions is sometimes commutative.

Under certain circumstances, they can be the same. However, most of the time, they are not commutative.

For instance, if we have f(x)=x^2 and g(x)=x^3, then:

$f(g(x))=(x^3)^2=x^6\text{ and}\\g(f(x))=(x^2)^3=x^6$
