Part 1 out of 2 For today's homework, you will need to recreate work the teacher did last night on their computer. The teacher drew a triangle with vertex A at (1, 4) and vertex B (3, 2). The teacher then transformed it to produce the triangle shown below. You need to find the teacher's original triangle and the transformations they used to create this image. Choose the correct way to find the transformations. Select all that apply. (Hint: It is a rigid transformation.)

A Translate by 〈2, 5〉, then reflect over the line x = 3.
B Translate by 〈2, 5〉 then reflect over the line x = 5.
C Rotate 180° about (4, 2), then reflect over the line y= 5.
D Reflect triangleABC over the line x = 3 then translate by 〈2, 5〉.

Step-by-step explanation:

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

step-by-step explanation:

one of the most important purposes of surface treatment is to alter surface properties according to the requirement of specific applications. for example, hydrophobic coating has been utilized on windshield and eyeglasses. gold atom monolayer on substrate has become a popular surface bioconjugation strategy.
