Tatami mats are used as a floor covering in Japan. one possible layout uses four identical rectangular mats and one square mat.

Basile [38]

So by definition, area is equal to the length (x) times the width (y). The area of the square mat is = x × y, or xy
If the area of<span> the rectangular mat is twice that of the square mat, the area of the rectangular mat would have to be = 2 </span>× x × y<span>
This can be written as 2x </span>× y, making the length of the rectangular mat twice that of the square mat's length, and the width the same as the square mat's width.<span>

Which function could be a stretch of the exponential decay function shown on the graph?

dezoksy [38]

Answer:

f(x) = $(\frac {1}{2})^{(6x)}$

Step-by-step explanation:

The given options are,

a) f(x) = $2^{(6x)}$

b) f(x) = $(\frac {1}{2})^{(6x)}$

c) f(x) = $2 \times (\frac {1}{6})^{x}$

d) f(x) = $\frac {1}{2} \times (\frac {1}{6})^{x}$

Now, clearly a) is a monotonically increasing function, hence discarded, and both of c) and d) don't pass through (0, 1) hence they are also discarded.

Only b) is a decay function which does also pass through (0, 1), hence, b) is the correct option.

The length of a rectangle is 3cm more than the width. The area is 70cm^2. Find the dimensions of the rectangle

Rom4ik [11]

Let width be x
Length would be x + 3
Area = L * W
Make an equation
(x) * (x+3) = 70
x^2 + 3x = 70
x^2 + 3x - 70 = 0
Quadratic formula
(-3 +/- rt 3^2 - 4 * 1 * (-70))/(2 * 1)
x1 = (-3 + 17)/2, x2 = (-3-17)/2
x = 7, x = -10
Dimension cannot be negative

Solution: width = 7
Length = 10
