ΔCAR has coordinates C (2, 4), A (1, 1), and R (3, 0). A translation maps point C to C' (3, 2). Find the coordinates of A' and R
shutvik [7]

Answer:

A'= (2,-1) and R'=(4,-2) under this translation.

Step-by-step explanation:

A translation in R^{2} is a mapping T from R^{2} to R^{2}  defined by T(x,y) = (x + v_1,y+v_2), where v=(v_1,v_2) is a fixed vector in R^{2}.

From the problem we know that T(2,4)=(3,2), so we need to find the values v_1 and v_2 such that  T(2,4) = (2 + v_1,4+v_2)=(3,2), so 3=2 + v_1 and 4+v_2=2, thus v_1=1 and v_2=2.

Then T(x,y) = (x + 1,y-2) and  

T(1,1)=(1+1,1-2)=(2,-1)=A'

T(3,0)=(3+1,0-2)=(4,-2)=R'

Therefore A'= (2,-1) and R'=(4,-2). The triangles CAR and C'Q'R' are shown in the figure below.

algol [13]

According to the graph, Neha's income is has_5 thousand dollars per month_, and she has_ 10 dinners out per month_.

<h3>How to complete the blanks?</h3>

Here we want to complete:

According to the graph, Neha's income is has_______, and she has_______.

We know that the blue point on the graph shows Neha's data. The horizontal axis shows the income, and the vertical axis shows the quantity (dinners per month).

Now, if the coordinates of the blue point are (5, 10). This means that her income is 5 thousand dollars per month, and that she has 10 dinners out per month, then:

According to the graph, Neha's income is has_5 thousand dollars per month_, and she has_ 10 dinners out per month_.
