TOY has coordinates T (-3, 4), O (-4, 1) and Y (-2, 3). a translation maps point T to T' (-1, 1). find the coordinates of O' and

NeX [460]

Answer:

Answer: The correct option is (A) O' (−2, −2); Y' (0, 0).

Step-by-step explanation: Given that the co-ordinates of the vertices of ΔTOY are T(−3, 4), O (−4, 1), and Y (−2, 3). A translation maps point T to T' (−1, 1).

We are to find the co-ordinates of the points O' and Y'.

The given transformation from T to T' is

T(−3, 4) ⇒ T' (−1, 1).

Let, (−3 + x, 4 + y) = (-1, 1).

So,

and

That is, the transformation rule is

(a, b) ⇒ (a+2, b-3).

Therefore,

co-ordinates of O' are (-4+2, 1-3) = (-2, -2),

and

co-ordinates of Y' are (-2+2, 3-3) = (0, 0).

Thus, the required co-ordinates of O' and Y' are (-2, -2) and (0, 0) respectively.

Option (A) is correct.

Answer B Im confused

Finger [1]

Answer:

120 degrees

Step-by-step explanation:

interior angle of regular polygon = [ ( n − 2 ) × 180 ] / n

n = number of sides

hence, in b), n = 6

interior angle of regular polygon = [ ( 6 − 2 ) × 180 ] / 6 = 120

$\bf \begin{array}{ccll}
\stackrel{\textit{years since 2000}}{t}&\stackrel{population}{p}\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
2&29400\\
5&36000
\end{array}\\\\
-------------------------------\\\\
\begin{array}{lllll}
&x_1&y_1&x_2&y_2\\
% (a,b)
&({{ 2}}\quad ,&{{ 29400}})\quad 
% (c,d)
&({{ 5}}\quad ,&{{ 36000}})
\end{array}$

$\bf slope = {{ m}}= \cfrac{rise}{run} \implies 
\cfrac{{{ y_2}}-{{ y_1}}}{{{ x_2}}-{{ x_1}}}\implies \cfrac{36000-29400}{5-2}\implies \cfrac{6600}{3}
\\\\\\
2200
\\\\\\
% point-slope intercept
\stackrel{\textit{point-slope form}}{y-{{ y_1}}={{ m}}(x-{{ x_1}})}\implies \stackrel{y}{p}-29400=2200(\stackrel{x}{t}-2)
\\\\\\
p-29400=2200t-4400\implies p(t)=2200t+27200$

how many in 2007? well, 2007 is 7 years after 2000, thus set t = 7,to get p(t).
