Classify the sequences of transformations based on whether or not they prove the congruency of the shapes by mapping shape Ionto shape Il 1.a reflection across the y-axis, followed by a 90° clockwise rotation about the origin, and then a translation left 18 units

2. a 90° clockwise rotation about the origin and then a translation left 18 units

3. a 90° counterclockwise rotation about the origin, followed by a reflection across the w-axis, and then a translation left 18 units

4. a 90° clockwise rotation about the origin, followed by a reflection across the y-axis, and then a translation right 2 units

5. a 180° rotation about the origin, followed by a reflection across the y-axis, and then a 90° clockwise rotation about the origin

6. a reflection across the v-axis, followed by a 90 counterclockwise rotation about the origin, and then a translation right 2 units

group 1 maps shapes l onto shapes ll

group 2 does not map shape l onto shape ll

That number goes with what group​

answer: yes i agree that you should not put it on/p>

step-by-step explanation: the reason for this is that it wastes other peoples time and also make them fail as well and that is never good.

answer: ratio of volume of cone (with 3 times the height and equal diameter) to volume of cylinder is 2 to 1. the value of π is not used.

step-by-step explanation:

radius is diameter/2 = 4.

area of circle is π r^2.

volume of cylinder is height × area of base = hπr^2 = 3(4^2) π = 48π cubic inches.

not knowing the formula for volume of cone, i calculate it using calculus (which is for calculating things).

volume of cone is integral 0 to h area(y) dy. area(y) is π r(y)^2. r(y) runs r to zero as y runs zero to h, r(0) = r, r(h) = 0.

r(y) = r - r/h y

area(y) = π (r - r/h y)^2 = π (r^2 - 2r^2y/h + r^2y^2/h^2) = π r^2(1-2y/h+y^2/h^2)

antiderivative area(y) = π r^2 (y-y^2/h+y^3/(3h^2))

integral 0 to h = π r^2(h-h^2/h+h^3/(3h^2) - (0)) = π r^2(h - h + h/3) = π r^2(h/3) = π/3 r^2 h

volume of this cone is π/3(4^2)18 cubic inches.

= 6 16 π = 96π cubic inches.

cone has twice the volume, 96/48.

cone height is 6 times the cylinder.

ratio of volume formula: π r^2 cancels.

cone over cylinder ratio is 6h/3 to h, 2 to 1.
