Answer:
Step-by-step explanation:
Rotations are easy when its multiples of 90 degrees; 90,180,270,360. Treat them like they’re a complex number like [x+yi]*i=[-y,xi] so rotating by 90 degrees and 180 is i squared [-1]! So [-3,2] rot90 is [-2,-3].
Reflection about the y=x line is change places. [x.y]=[y,x].
So [-2.-3] reflected about the y=x line is [-2.-3]=[-3.-2],
Compile a list of these transform is best practice technique in this area.

Answer:
<u><em>The area of Triangle K is 160</em></u>
Step-by-step explanation:
First, the question explains how <u>Triangle K was a scale factor of 4</u>, with <u>Triangle J being the original</u>. To find the dimensions of Triangle K, you multiply Triangle J's measurements by 4:
4 x 4 = 16
5 x 4 = 20
Now we know the dimensions of Triangle K, it's time to find the area;
<em>Formula for finding area of a triangle:</em> (H x B) / 2
16 (Height) multiplied by 20 (Base) is <u>320</u>.
Now, we divide 320 by 2 to find our answer:
320 divided by 2 is <u>160</u>.
<u>160 will be your answer.</u>

Answer:
The probability of 10 heads after flipping a fair coin fairly, 10 times = 1/(2^10) = 1/1024 =.0009765625 ~ 0.1% and such an outcome suggests the coin may be skewed in favor of heads. If this particular coin is fair though, the probability of tossing a head after tossing 10 heads in a row remains = 1/2, the same as for a tail.
