Mathematics has helped organize patterns and consistencies in the world because one must know that there is always mathematics in almost everything in this world. An example is an arrangement or grouping that repeats.

Suppose you have line AB on a coordinate plane located at A(-3,-4) and B(5,-4). Under a dilation centered at (9,0), line AB

masya89 [10]

Answer:

$\dfrac{1}{4}$

Step-by-step explanation:

Center of dilation: O(9,0).

Line AB with A(-3,-4) and B(5,-4) is dilated with the scale factor k and center of dilation at O to form line A'B' with A'(6,-1) and B'(8,-1).

Then

$OB'=kOB\\ \\OA'=kOA$

Since

$OB'=\sqrt{(8-9)^2+(-1-0)^2}=\sqrt{1+1}=\sqrt{2}\\ \\OB=\sqrt{(5-9)^2+(-4-0)^2}=\sqrt{16+16}=4\sqrt{2},$

then

$\sqrt{2}=k\cdot 4\sqrt{2}\\ \\k=\dfrac{1}{4}$

Pls answer this questionnnn

pickupchik [31]

Jo makes 170 minutes call. There are 150 free ones
170 - 150 = 20
20 minutes are "what Jo has to pay"
Jo sends 182 texts. There are 150 free ones
182 - 150 = 32
32 texts are "what Jo has to pay"

Monthly charge = 16p, 13p for each extra minute, 15p for each extra text.
13(20) = 260p
15(32) = 480p

480p + 260p + 16 = 740p + 16

740p + 16 is your answer (if p = pounds, add 16 to it, i'm not sure what p stands for though. If it is cents, divide 100 from 740 and take out the p, then add total to 16 to get answer.)

hope this helps
