The difference between Pre-Image and Image is given as follows:

  • Image is the shape AFTER a transformation is the picture of the transformation.
  • A transformation's preimage is the shape BEFORE the change.

<h3>How do you define relationships between Image and Preimage?</h3>

Usually, the difference between image and pre-image is the way or method of transformation.

<h3>What is transformation in math?</h3>

A transformation is a broad phrase covering four distinct methods of changing the shape and/or location of a point, line, or geometric figure.

The Pre-Image is the original shape of the item, and the Image during the transformation is the final shape and location of the object.

The types of transformation in math are;

  • translation
  • rotation
  • reflection, and
  • dilation.

Ms. Nina has 10 lbs of 25% sugar syrup. How much water does she need to add to make 10% sugar syrup?
ryzh [129]
She has 10lbs of 25% syrup... so, in the 10lbs, 25% of that is syrup, the rest, namely the 75% remaining is water or other substances.

let's say she adds "x" lbs of water, to get "y" lbs for the 10% mixture.

how much is 25% of 10lbs?  well, (25/100) * 10, or 2.5.

the water has no sugar syrup in it, so is just pure water, so the amoun of syrup in it is 0%, how much is 0% of "x" lbs?  well, (0/100) * x, or 0.00x, which is just 0.

how much is 10% of "y" lbs?  well (10/100) * y, or 0.10y.

whatever "x" and "y" are, we know that 10 + x = y.

we also know that the syrup amount in that is also 2.5 + 0.00x = 0.10y, thus


\bf \begin{array}{lccclll}&#10;&\stackrel{lbs}{syrup}&\stackrel{concentration~\%}{syrup}&\stackrel{concentration}{amount}\\&#10;&------&------&------\\&#10;\textit{25\% syrup}&10&0.25&2.5\\&#10;\textit{pur water}&x&0.00&0.00x\\&#10;------&------&------&------\\&#10;\textit{10\% mixture}&y&0.10&0.10y&#10;\end{array}&#10;\\\\\\&#10;\begin{cases}&#10;10+x=\boxed{y}\\&#10;2.5+0.00x=0.10y\\&#10;----------\\&#10;2.5 = 0.10\left( \boxed{10+x} \right)&#10;\end{cases}&#10;\\\\\\&#10;2.5=1 + 0.10x\implies 1.5=0.10x&#10;\\\\\\&#10;\cfrac{1.5}{0.10}=x\implies 15=x

morpeh [17]

Diameter of each hemispheral holes = the diameter of a full sphere = side length of cube = 2 units.

<h3>What is a Hemisphere?</h3>

A hemishpere is half of a sphere. Thus, two hemispheres makes one full sphere.

Given the image as shown below, since the identical hemispheral holes are centered at the center of each fce and they touch each other at only one point, it means that two hemisphere meet to make one full sphere.

Therefore, the diameter of a full sphere = side length of cube.

Thus, diameter of each hemispheral holes = the diameter of a full sphere = side length of cube = 2 units.
