If triangle ABC is dilated using a scale factor of 2, what will be the coordinates of A after the transformation

harkovskaia [24]

Answer:

$A' = (-4,4)$

Step-by-step explanation:

Given

$A = (-2,2)$ $B = (1,3)$ $C = (1,0)$

$k =2$ --- scale factor

Required

Determine A'

This is calculated as:

$A' = A * k$

$A' = (-2,2) * 2$

$A' = (-2 * 2,2 * 2)$

$A' = (-4,4)$

(30a^2 -11a+15)(5a-6)^-1

denis-greek [22]

$(30a^2-11a+15)(5a-6)^{-1}= (30a^2-11a+15)/(5a-6)\(5a-6)(6a+5)/(5a-6)\6a+5$

The final simplified answer is 6a + 5.

EFGH is a rhombus. Given EG = 16 and FH = 12, what is the length of one side of the rhombus?

Black_prince [1.1K]

Answer:

Step-by-step explanation:

It is given that EFGH is a rhombus and EG = 16 and FH = 12.

We know that the diagonals of the rhombus are the perpendicular bisectors, therefore OF=6, OH=6, OE=8 and OG=8.

Now, using the Pythagoras theorem in ΔOFG, we have

$(FG)^{2}=(OG)^{2}+(OF)^{2}$

$(FG)^{2}=(8)^{2}+(6)^{2}$

$(FG)^2=64+36$

$FG=\sqrt{100}$

$FG=10$

Thus, the value of the side of the rhombus will be 10 units.

Hence, option C is correct.
