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

$A' = (3,-1)$

$B' = (4,1)$

$C' = (5,-2)$

Answer:

48∛9 ft²

Step-by-step explanation:

The length (L) and width (W) are given by:

$L = 4\sqrt[3]{24}\\ W= 6\sqrt[3]{3}$

Since this is a rectangular region, the area is given by:

$A=L*W=L \\A=4\sqrt[3]{24}* 6\sqrt[3]{3}\\A=24\sqrt[3]{72}\ ft^2$

The answer can be further simplified by factoring as follows:

$A=24\sqrt[3]{72} = \\A=24\sqrt[3]{2*2*2*3*3}= 24\sqrt[3]{2^3*9}\\A=48\sqrt[3]{9}\ ft^2$

The exact area is its simplest form is 48∛9 ft²

What is the coefficient of the c-term of the algebraic expression 14a - 72r - c - 34d? A) -34

natima [27]

When the coefficient of a term is 1 or -1, we don't write it, we just use the + or - sign. The coefficient of the c term is -1, because of the - sign in front of it and the lack of written coefficient. Any questions?
