Write the coordinates of the vertices of a triangle A'B'C' that results from a translation of triangle ABC two units to the righ
gayaneshka [121]

Answer:

A'(4,-6) , B'(0,1), C'(-2,-2)

Step-by-step explanation:

From the given graph the coordinates of ΔABC area A (2,-2), B(-2,5) and C(-4,2)

If a translation is applied on ΔABC two units to the right and four units down  to create ΔA'B'C'.

Then to find the coordinates of ΔA'B'C' will be we need to apply the translation rule

(x,y)\rightarrow(x+2,y-4)

Now, A(2,-2)\rightarrow A'(2+2,-2-4)=A'(4,-6)

B(-2,5)\rightarrow B'(-2+2,5-4)=B'(0,1)

and C(-4,2)\rightarrow C'(-4+2,2-4)=C'(-2,-2)

The length of a rectangle is 3 feet more than the width. If the perimeter is 82 feet, what are the length
Tems11 [23]

Answer:

L=22feet

w=19feet

Step-by-step explanation:

Perimeter(p)=82

Length=(L)

Width=(w)

P=2L+2w

2L+2w=82 .......(1)

L-w=3........(11)

From (11) L=3+w

Substitute L=3+w in (1)

2(3+w)+2w=82

Clearing brackets

6+2w+2w=82

6+4w=82

Collect like terms

4w=82-6

4w=76

w=76/4

w=19

Substitute w=19 in (11)

L-19=3

Collect like terms

L=3+19

L=22

If a bird is sitting 30m along the first wall and a cat is 34m along the top of the other wall, how far apart are the cat and th
Varvara68 [4.7K]
Draw a right triangle. The cat represents a side, the bird represents a side. Then just use the Pythagorean Theorem to find the hypotenuse. a^2 + b^2 = c^2. Let a = cat; b = bird; then solve for c.
