Rotate triangle ABC 90° clockwise around the origin given the vertices A(1,3)B(-1,4)C(2,5) what are the new vertices for triangl

fgiga [73]

Answer:

$A' = (3,-1)$

$B' = (4,1)$

$C' = (5,-2)$

Step-by-step explanation:

Given

$A = (1,3)$

$B = (-1,4)$

$C = (2,5)$

Rotation: 90 degrees clockwise

Required

Determine A'B'C'

When a point $P (x,y)$ is rotated 90 degrees in the clockwise direction, the new coordinates is: $P' (y, -x).$

So, we have:

$A = (1,3)$

$B = (-1,4)$

$C = (2,5)$

Becomes

$A' = (3,-1)$

$B' = (4,1)$

$C' = (5,-2)$

F = uv/u + v make u the subject

never [62]

I'm assuming that you mean

$\dfrac{uv}{u+v}$

because if you meant

$\dfrac{uv}{u}+v$

then u would simplify and you couldn't make it the subject.

Under this assumption, we start with

$F=\dfrac{uv}{u+v}$

We multiply both sides by $u+v$

$F(u+v)=uv$

We expand the left hand side:

$Fu+Fv=uv$

We move all terms involving u to the left and all terms not involving u to the right:

$Fu-uv=-Fv$

We factor u on the left hand side:

$u(F-v)=-Fv$

We divide both sides by $F-v$

$u=\dfrac{-Fv}{F-v}$
