Two quadrilaterals are similar. The length of the row longest sides of the first quadrilateral are 40in and 60in. The lengths of

Andreyy89

Answer:

The sides of the first quadrilateral are 60 in, 40 in, 30 in and 12,5 in

The sides of the second quadrilateral are 24 in, 16 in, 12 in and 5 in

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its corresponding sides is proportional, and this ratio is called the scale factor

Arrange the sides of each quadrilateral from largest to smallest

First quadrilateral Second quadrilateral

Longest side=60 in Longest side=c in

Second side=40 in Second side=16 in

Third side= a in Third side= 12 in

Fourth side=b in Fourth side=5 in

$\frac{60}{c}=\frac{40}{16}=\frac{a}{12}=\frac{b}{5}$

Find the value of c

$\frac{60}{c}=\frac{40}{16}$

$c=60(16)/40$

$c=24\ in$

Find the value of a

$\frac{40}{16}=\frac{a}{12}$

$a=40(12)/16$

$a=30\ in$

Find the value of b

$\frac{40}{16}=\frac{b}{5}$

$b=40(5)/16$

$b=12.5\ in$

Is the relationship between the variables in the table a direct variation, an inverse variation, or neither? If it is a direct o

inn [45]

Answer: neither direct variation nor inverse variation.

Explanation:

1) The relation between two variables, y and x, is a direct variation if and only if the quotient between them, y/x, is constant. This is: y / x = k or, equivalently, y = kx.

Note that if y / x is constant, x / y is also constant.

In a direct variation, when x increases, y increases, and when x decreases, y decreases.

2) The relation between two variables, y and x, is an inverse variation if and only if their product, y×x is constant. This is: y × x = k or, equivalently y = k /x or x = k / y.

In an inverse variation when one of the variables increases the other decreases.

3) Writhe the given table and study whether the conditions for direct or inverse variation are met:

x y y/x y×x

-6 -72 -72/(-6) = 12 (-6)(-72) = 432

-4 -47 -47 / (-4) = 11.75 (-4)(-47) = 188

-3 -36 -36 / (-3) = 12 (-3)(-36) = 108

1 12 12 / 1 = 12 (1)(12) = 12

Conclusions;

a) Since neither y / x nor y×x have the same result for every pair, the relation is neither direct nor inverse.

b) Note that if the third pair were (-4, -48) instead of (-4, -47), y / x would be 12, which make a direct variation. In this case the function that modeled it would be:

y = 12x.

I WILL GIVE BRAINLIEST. HURRY PLEASE

notsponge [240]

Answer:

Concept: Linear Algebra

Let us pick -5 and -4 which are one unit apart.
We will find the difference by finding the slope: -3-(-11)/-4-(-5)= 8
Next for 2 units apart we will choose 1 and 3
We do the same thing: 53-37/3-1= 16/2=8
Next we will pick something 2 units apart. Let's pick 0 and 3
Hence we will do the same: 53-29/3-0= 24/3=8
No matter what difference we pick, whether that be one, two or three units, the difference is the same and consistent.
