Emergency test! will make brainliest! triangle mno is rotated 180 using the origin as the center of rotation. which sequences of transformations will produce the same results? check all that apply. a reflection over the x-axis and then a reflection over the y-axis a reflection over the y-axis and then a reflection over the x-axis a 90 clockwise rotation about the origin and then a 90 counterclockwise rotation about the origin a translation 6 units right and then a reflection over the x-axis a translation 4 units down and then a reflection over the y-axis

a reflection over the x-axis and then a reflection over the y-axis  

and

a reflection over the y-axis and then a reflection over the x-axis

Step-by-step explanation:

The third one would just have it end up where it started.

The fourth and fifth one would not work because simply translating the triangle would not provide the symmetry along the axis' and essentially the two triangles are x-axis and y-axis reflections  

a reflection over the x-axis and then a reflection over the y-axis

a reflection over the y-axis and then a reflection over the x-axis

Step-by-step explanation:

Just took the test got it right

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions

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.
