Answer:
<h2>The answer is option A</h2>
Step-by-step explanation:
Area of a circle = πr²
where
r is the radius of the circle
From the question
r = 15.2 cm
The area of the circle is
A = (15.2)²π
= 231.04π
= 725.833566685386...
We have the final answer as
<h3>725.8 cm²</h3>
Hope this helps you
Answer:
-1.
Step-by-step explanation:
(tanx- secx) (tanx+ secx).
= tan^2 x + tanx sec x- tanx sec x - sec^2x
= tan^2 x - sec^2 x.
But sec^2 x = 1 + tan^2 x
so tan^2 x - sec^2 x = -1
Answer:
y = 1x +1
Step-by-step explanation:
1 is your b, you go up 1 over 1, 1/1, which equals 1. so your awnser is y=1x+1 :)

Answer:
- R'(-2, 2)
- F'(2, 2)
- G'(-2, -2)
Step-by-step explanation:
It can be useful to keep a list of the 90° rotation transformations.
(x, y) ⇒ (-y, x) . . . . . . 90° CCW, 270° CW
(x, y) ⇒ (-x, -y) . . . . . . 180°
(x, y) ⇒ (y, -x) . . . . . . . 270° CCW, 90° CW
__
1) (x, y) ⇒ (-x, -y) . . . . 180°
R(2, -2) ⇒ R'(-2, 2)
__
2) (x, y) ⇒ (-y, x) . . . . 90°
F(2, -2) ⇒ F'( 2, 2)
__
3) (x, y) ⇒ (y, -x) . . . . 270°
G(2, -2) ⇒ G'(-2, -2)
