Answer:

A'(4,-2) B'(0,-5) C'(-2,-2) D'(2,1)

Step-by-step explanation:

The given parallelogram has coordinates A(1, 1), B(5, 4), C(7, 1), and D(3, -2).

The rotation of 180\degreeabout the origin  has the mapping;

P(x,y)\rightarrow P'(-x,-y)

This implies that;


A(1,1)\rightarrow (-1,-1)


B(5,4)\rightarrow (-5,-4)


C(7,1)\rightarrow (-7,-1)


D(3,-2)\rightarrow (-3,2)


A translation of  5 units to the right and 1 unit down has the mapping;


P(x,y)\rightarrow P'(x+5,y-1)


We apply this to the resulting coordinates to obtain;

A(1,1)\rightarrow (-1,-1) \rightarrow (-1+5,-1-1)=A'(4,-2)


B(5,4)\rightarrow (-5,-1) \rightarrow (-5+5,-4-1)=B'(0,-5)


C(7,1)\rightarrow (-7,-1)\rightarrow (-7+5,-1-1)=C'(-2,-2)


D(3,-2)\rightarrow (-3,2)\rightarrow (-3+5,2-1)=D'(2,1)

List the sides of each triangle from shortest to greatest
Lelechka [254]
In every triangle, the largest side, is opposite the largest angle.

Also, the smallest side, is opposite the smallest angle.


a.70^o\ \textgreater \ 60^o\ \textgreater \ 50^o so |RQ|\ \textgreater \ |PR|\ \textgreater \ |PQ|, 

because RQ is opposite angle P, the largest,
PR is opposite angle Q , the middle
and PQ is opposite angle R, the smallest.

Greatest side: RQ


b. The sum of the measures of the interior angles of any triangle is 180°, 

so 

m(A)+m(B)+m(C)=180^o\\\\50^o+45^o+x=180^o\\\\x=180^o-50^o-45^o=85^o

thus, m(C) is the largest angle. This means the largest side is the side AB.



Answers:

a) RQ
b)AB

A building measure 8.4m wide by 9.3 the rest is in picture
Bad White [126]

Answer:

26.309932 MN  if gravity was normal gravity force and on basis salt water was 1030 kg/m3

Step-by-step explanation:

The rule below is something I just found.

To calculate the force of gravity of an object, use the formula: force of gravity = mg, where m is the mass of the object and g is the acceleration of the object due to gravity. Since g is always 9.8 m/s^2, just multiply the object's mass by 9.8 and you'll get its force of gravity

Find the domain in interval notation.
Nady [450]

Answer:

<em>x ∈ ( - ∞ , - 8 ) ∪ ( - 8 , 0 ) ∪ ( 0 , 8 ) ∪ ( 8 , ∞ ) </em>

Step-by-step explanation:

x³ - 64x = x( x² - 64 ) ≠ 0 ⇒ x ≠ 0 and x ≠ ± 8

<em>x ∈ ( - ∞ , - 8 ) ∪ ( - 8 , 0 ) ∪ ( 0 , 8 ) ∪ ( 8 , ∞ )</em>
