Answer:

Step-by-step explanation:

a) Let's x the length of the side of the small square.

Thus,

x^{2}  + (\sqrt{40})^2 = (\sqrt{50})^2

x^{2}  + 40 = 50

x^{2}  = 50 - 40

x^{2}  = 10

x = \sqrt{10}

x=3.16

b) Now, the area of the small square is

A= x^{2}

A=(3.16)^2

A=9.99

Make a function table to represent his total savings for 2,4,6,8 and 10 months.
OlgaM077 [116]
Well, let's say that bananas cost $1.60 per pound. That means that at step 0 the value is 0, at step 1 the value is$1.60, at step 2 the value is $$3.20 and so on. To make a table from this we'd need two columns and four rows. On the top row we right step followed by amount. In the step column, we list the numbers 0-2. In the amount column we list 0, $1.60, and $3.20. In the end, a function table looks like this:

I really need help <br> Dz,2 of X is<br> (0-4)<br> (2,-2)<br> (6,2)

Answer:

  (6,2)

Step-by-step explanation:

As is often the case with multiple-choice problems, you don't actually need to know the detailed working. You just need to know what the answer looks like.

When point X is dilated by a factor of 2 with point Z as the center of dilation, it will move to a location twice as far from Z. You can tell by looking at the graph that X' will be in the first quadrant, above and to the right of the location of X. The only sensible answer choice is ...

  X' = (6, 2)

_____

<em>Additional comment</em>

X is a distance of X-Z = (4, 0) -(2, -2) = (2, 2) from Z Doubling that will put the image point a distance of 2(2, 2) = (4, 4) from Z. When this is added to Z, we find ...

  X' = Z + (4, 4) = (2+4, -2+4) = (6, 2)
