The coordinates of the vertices of △PQR are P(1, 4) , Q(2, 2) , and R(−2, 1) . The coordinates of the vertices of △P′Q′R′ are P′

butalik [34]

ANSWER

The correct answer is option B

EXPLANATION

When we analyse carefully we can see that PQR is mapped on to P'Q'R' by the rule

$(x,y)\rightarrow (-x,y)$

$P(1,4)\rightarrow P'(-1,4)$

$Q(2,2)\rightarrow Q'(-2,2)$

$R(-2,1)\rightarrow R'(2,2)$

That is to say the x-coordinates are negated. Hence y-axis is the mirror line.

Since reflection is a rigid motion, the two triangles are congruent. That means the two triangles PQR and P'Q'R' are equal in all respect.

amm1812

the population of squirrels in a forest after 3x years: f(x) = 30(1.03)3x
By multiplying 1.03 with 3 will make it 3.0900.This will not effect the parent function and thus the equivalent expression for the given function will be f(x) = 30(3.0900)x
f(x) = 30(1.03)3x ====> f(x) = 30(3.0900)x
