What the algebraic rule for a dilation with a scale factor of 3

Mathematics
1 answer:
Marianna [84]4 years ago
7 0

Step-by-step explanation & answer:

When a dilation in the coordinate plane has the origin as the center of dilation, we can find points on the dilated image by multiplying the x and y coordinates of the original figure by the scale factor.

For example, if the scale factor is "k", the algebraic representation of the dilation is

(x, y) → (kx, ky)

For enlargements, k > 1 and for reductions, k < 1.

Hope this is what you needed:)

Joelle wants to place an oversized image which is 30.51 cm wide so that it appears centered on the page. The width of the page i
Naya [18.7K]

-4.46cm

Step-by-step explanation:

The horizontal midpoint of the page is;

The horizontal midpoint of the image is given as;

For the image to be centered, these to midpoints must be on the same point in the axis.

If we take the leftmost edge of the paper to be point zero on the axis, then, the distance accommodated by the paper is 10.795cm.  The distance that goes beyond this leftmost edge is computed as;

On the axis, this is on the negative side. Therefore, the horizontal position for the left edge of the image that Joelle should use to center the image is -4.46cm.

"determine the ratio of the volume of a" cone to the volume of a cylinder with the same height and base radius:
hichkok12 [17]
Volume of cone is 10
if the radius is r and height is h
while volume of cylinder is pi r 2nd power h,
volume of cone is 1/3 pi r 2nd power h.
hence with same r and h the volume of cone is one-third of that of cylinder and hence 
volume of cone is 10.

X + 2y = -3 x - y = -12
Nastasia [14]

Answer:

x = -9, y =3

Step-by-step explanation:

x + 2y = -3

x - y = -12

Subtract to two equations to eliminate x

x + 2y = -3

-x + y = 12

---------------------

   3y = 9

Divide each side by 3

3y/3 = 9/3

y = 3

Now we can find x

x-y =-12

x - 3 = -12

Add 3 to each side

x-3+3 = -12+3

x = -9

A client is withdrawing $105.83. He would like $40 in $10 bills and the rest in the fewest number of bills and coins possible. S
Gennadij [26K]

Answer:

Step-by-step explanation:

The client starts with 105.83 dollars

He requests 40 of which to be subtracted in denominations of 10, meaning 4 10 dollar bills are being removed.

After this he has 65.83 more dollars to withdraw, the next biggest bill denomination is a 50, so lets subtract 50 from our account.

Now he is left with 15.83, subtract another 10 dollar bill.

That leaves us with 5.83, subtract one 5 dollar bill.

Leaving us with 0.83, subtract 3 quarters

That leaves us with 8 cents, lets subtract one nickel, leaving us with 3 cents.

Now with those 3 cents we can subtract 3 pennies.

Meaning the least amount of denominations required is:

1 50-Dollar bill

5 10-Dollar bills

1 5-Dollar bill

3 Quarters

1 Nickel

3 Pennies
