Answer:

Given a rectangle with length l and width w, the formula for the area is: A = lw (rectangle). That is, the area of the rectangle is the length multiplied by the width. As a special case, as l = w in the case of a square, the area of a square with side length s is given by the formula: A = s2 (square).

Consider the expression: (x + 3)•(y + 1)•(x + 2)
emmainna [20.7K]

Answer:

Step-by-step explanation:

First we multiply x through (y+1). This equals xy +x.

Second we take 3 through (y+1). This equals 3y+3.

Next we take xy + x through (x+2). This equals 2x squared, y + 2x squared.

Fourth we take 3y+3 through (x+2). This equals 6xy + 6x.

Ines has saved $5. She doubles the amount she saves each week. Does the function have a constant difference or a constant ratio?
salantis [7]

Answer:

The function have a constant ratio

No, it does not represent an exponential function.

Step-by-step explanation:

As given,

Ines has saved $5. She doubles the amount she saves each week.

⇒ In first week she saved = $5

   In second week she saved = 2×$5 = $10

   In third week she saved = 2×$10 = 20

  In fourth week she saved = 2×$20 = 40

and so on..

∴ we get the series

5, 10, 20, 40 ,.......

If the series is given as a, b, c, d, ..... , then

The common difference is defined as d = b-a = c-b

The common ration is defined as r = \frac{b}{a} = \frac{c}{b}

Here, in the given question

The series is - 5, 10, 20, 40

This has no common difference , d =   10 - 5 (= 5 )≠ 20 - 10 (= 10)

As 5 ≠ 10

So the function does not define common difference .

Now,

This has common ratio , r =  \frac{10}{5} (=2) = \frac{20}{10}(=2)

As 2 = 2

So, the function represent common ratio

Now,

The function does not represent an exponential function because it is increased by common ratio.

Which transformation would create an image and a pre image that are similar figures?
Crank

Answer:

Dilation

Step-by-step explanation:

A dilation changes the size of a figure by enlarging the figure of making the figure smaller.  The sides will be proportional and the angles will be congruent making the figures similar.
