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

$A' = (3,-1)$

$B' = (4,1)$

$C' = (5,-2)$

What is the coeffieent of (x^4)(y^4) in the expansion of (x+y)^8

kap26 [50]

ANSWER

The coefficient is 70.

EXPLANATION

The given binomial expression is

$(x+y)^8$

The specific term of a binomial expansion can be determined using the formula,

$T_{r+1}= nC_ra^{n-r}b^r$
where

$n=8,r=4,a=x,b=y$

We substitute these values into the formula to get,

$T_{4+1}= 8C_4x^{8-4}y^4$

We simplify to get,

$T_{5}= 70x^{4}y^4$

Hence the coefficient is 70.
