Answer:
(x, y) ⇒ (-x, -y)
Step-by-step explanation:
There are a couple of ways you can go at this.
1) Rotation by 180° in either direction is the same as reflection across the origin. That reflection is identical to reflection across both the x- and y-axes, in either order, so negates both coordinates. The transformation rule is ...
(x, y) ⇒ (-x, -y)
__
2) The rule for a general rotation by angle α is ...
(x, y) ⇒ (x·cos(α) -y·sin(α), x·sin(α) +y·cos(α))
For α = 180°, sin(α) = 0 and cos(α) = -1. This makes the rule for rotation by 180° be ...
(x, y) ⇒ (-x, -y)
732.4 because just put in a decimal before a # and then do place value to a whole #.
Answer:
a. 7.54385 in^2
Step-by-step explanation:
surface area equation = 3.14 * r^2
diameter is 2 times radius
x=3.14 (1.55^2)
x=7.54385 in^2
p^1
q^4
r^2
Is this what your asking for and also can you please mark me as brainlist. Thank you
