Answer:
A: ∠W'Z'Y' = 60°; angles aren't changed by rotation
B: W'(-3, 6), X'(9, 6), Y'(8, 1), Z'(-4, 1)
Step-by-step explanation:
<u>Part A</u>:
Angle WZY is the supplement of the given angle ZWX, so is ...
∠WZY = 180° -120° = 60°
Rotation about the origin (or anywhere else) does not change angles. The new parallelogram will have ...
∠W'Z'Y' = 60°
__
<u>Part B</u>:
The transformation right 2 and up 3 can be described by ...
(x, y) ⇒ (x +2, y +3)
Then the translated vertices are ...
W(-5, 3) ⇒ W'(-3, 6)
X(7, 3) ⇒ X'(9, 6)
Y(6, -2) ⇒ Y'(8, 1)
Z(-6, -2) ⇒ Z'(-4, 1)
Answer:
11/7 feet
Step-by-step explanation:
the perimeter of a circle is πr²
and a semi circle is half of a circle then the formula would be 1/2 πr²
1/2×22/7×1 (it is 1 because we have divided the diameter to get radius
so we derived at 11/7
Answer:
The equation is y = 6x - 5
Step-by-step explanation:
The equation is y = mx + b
7 = 2m + b
-5 = b (since x = 0)
Plug back in the first.
7 = 2m - 5
2m = 12
m = 6
