R(3, 2), s (5, -2), and t (6, 0) are the coordinates of a triangle's vertices. if the triangle is reflected over the y-axis, what are the coordinates of the image? r'(-3, 2), s'(-5, -2), t'(6, 0) r'(-3, 2), s'(-5, -2), t'(-6, 0) r'(-3, -2), s'(-5, 2), t'(-6, 0) r'(3, -2), s'(5, 2), t'(6, 0)

ANSWER

R'(-3, 2), S'(-5, -2), and T'(-6, 0).

EXPLANATION

The vertices of the given triangle are:

R (3, 2), S (5, -2), and T (6, 0).

We want to find the vertices of the image triangle after a reflection over the y-axis.

The mapping for a reflection over the y-axis is given by:

We just have to negate the x-coordinates.

Hence the image triangle will have coordinates

R'(-3, 2), S'(-5, -2), and T'(-6, 0).

answer: the answer is (b) amie should have multiplied

step-by-step explanation: given a sphere and a cylinder with same radius and height.

let, 'r' be the radius of the cylinder and sphere and 'h' be the height of the cylinder. according to the question,

r = h.

now, the volume of the sphere will be

and the volume of the cylinder will be

therefore, we have

thus, ammie should have multiplied the volume of the sphere
