We have that
<span>A' (2,1)

C(-2,2)-------> </span>Using the transformation-----> C' (-2+2,2+1)----> C' (0,3)

with 
A' (2,1) and C' (0,3)
find the distance <span>C'A'

d=</span>√[(y2-y1)²+(x2-x1)²]----> d=√[(3-1)²+(0-2)²]----> d=√8----> 2√2 units

the answer is
the distance C'A' is 2√2 units

He should use the Pythagorean Theorem to find the missing length.


Since KT is tangent to the circle and TL reaches the center of circle L, the measure of angle LTK is 90 degrees. This means that triangle LTK is a right triangle which means the Pythagorean Theorem can be used.

So,
TL²+(12)²=(13)²
=> TL²+144=169
=> TL²=25
=> TL = 5

Therefore, the radius of circle L is 5 feet.

If AB = 9 and BC = 12 then what is AC?
dimaraw [331]

Answer:

AC = 12 cm

Step-by-step explanation:

AB=9 centimeters, you figure out what times what is 9. in this case, it is 3 for A and B. Then you go to BC=12 and 3 for B and 4 for C making it 12 So AC would equal 3x4.

Which of these expressions are equivalent? Show your work
ivanzaharov [21]

Answer:

7(2+3x)-3x and 4(3+3x)+2(1+3x)

Step-by-step explanation:

7(2+3x)-3x

= 14 + 21x - 3x

= 18x + 14

2(6x+7)+10x

= 12x + 14 + 10x

= 22x + 14

4(3+3x)+2(1+3x)

= 12 + 12x + 2 + 6x

= 18x + 14

7(2+3x)-3x and 4(3+3x)+2(1+3x) are equal expressions.
