Find the coordinates of the vertices of a triangle after a 90 degree rotation counterclockwise about the origin.

Mathematics
1 answer:
Oksana_A [137]3 years ago
7 0

Step-by-step explanation:

The rule for a 90 degree counterclockwise is

(x,y) -> (-y,x)

so

C(-1,2) -> C'(-2,-1)

D(3,5) -> D'(-5,3)

E(1,2) -> E'(-2,1)

Quick!!!<br> If the side lengths of a triangle are 23, 16, and 7; what type of triangle is it?
ololo11 [35]
<h3>No it does not form a triangle!~</h3>

Let's prove it by pythogoras theorem,

  • Hypotenuse = 23
  • Base = 7
  • Perpendicular = 16

\bf \: H^{2} =P^{2} +B^{2}

\sf \:  {23}^{2}  =  {16}^{2}  +  {7}^{2}

\sf \: 529 = 256 + 49

\sf \: 529  \cancel= 305

<h3>Hence (Proved) </h3>

Write an equation for the parabola whose vertex is at (3, 6) and which<br> passes through (4, 4).
34kurt

Answer:

<h3>            f(x) = -2 (x - 3)² + 6</h3>

Step-by-step explanation:

The vertex form of the equation of the parabola with vertex (h, k)  is:

f(x) = a(x - h)² + k

so the equation of parabola with the vertex (3, 6) is

f(x) = a(x - 3)² + 6  

passes through the point (4, 4) means: if x=4 then f(x)=4

4 = a(4 - 3)² + 6  

4 -6 = a(1)² + 6 -6

-2 = a

Therefore the equation of parabla is:

                                 <u> f(x) = -2 (x - 3)² + 6  </u>
