Marissa has a photograph that measures 2 in. by 4 in. She has mounted the picture on a mat so that there is a border that measures 1 in. around the picture. The graph shows a representation of the photograph and the mat on the coordinate grid. Marissa has decided to dilate the picture and the mat by a scale factor of 2. Draw the new image for the picture and mat on the coordinate grid.

Answer from: Hellokittyjam35

The new size of the picture is $4\times 8$ and the new size of the mat is $6\times8$ This is shown in attached images.

Given-

The size of the photograph is 2 by 4 in.

Marissa's photograph original size is 2 by 4 in. This is shown in the graph with image one.The boundary required for the mat is 1 in after the photograph applied. Thus the length of the mat must be 3 by 5 in. Refer Image two.When Marissa decided to the picture by the scale factor two she need to multiply its dimension with two.

Thus the new dimension of the Picture is,

$=2\times(2,4)$

=(4,8)

Hence the new size for the picture is 4 by 8 in. This is shown in graph in image three.When Marissa decided to dilate the mat by the scale factor two she need to multiply its dimension with two.

Thus the new dimension of the mat is,

$=2\times(3,5)$

=(6,10)

Hence the new size for the mat is 6 by 10 in. This is shown in graph in image four.

Hence the new size of the picture is 4 by 8 and the new size of the mat is 6 by 10. This is shown in attached images.

Answer from: rebecca7415

Step-by-step explanation:

The initial image of the photo is 2 in by 4 in. The mat is 4 in by 6 in.

The new image is dilated by a scale of 2. So we double the dimensions. The new photo is 4 in by 8 in. The new mat is 8 in by 12 in.

Answer from: Quest

whole numbers.

step-by-step explanation:

we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.

as we can see m is taken for the number of months for years 1900-2009.

we know that number of months can't be a negative number or decimal number or a fraction.

so, the number of months could be only positive whole numbers.

therefore, whole numbers is more appropriate for the domain of r.

Answer from: Quest

if you are looking for the unit rate then the answer would be 9 because unit rate is distance divided by time.
