Answer:
(4 , 1) ; (7 , 4) ; (11 , 1)
Step-by-step explanation:
Each of these are 3 points away from the original point, ( 7 , 1)
(7 - 3, 1) = (4 , 1)
(7 , 1 + 3) = (7 , 4)
(7 + 3 , 1) = (11 , 1)

Answer:
cos(2x) = 2cos²(x)-1
Step-by-step explanation:
We know the trigonometry identity as follows :
cos(2x) = cos²(x) – sin²(x) ....(1)
Also, sin²(x)+cos²(x) = 1
or
sin²(x) = 1-cos²(x)
Put the value of sin²(x) in equation (1)
cos(2x) = cos²(x) – (1-cos²(x))
= cos²(x) –1+cos²(x)
cos(2x) = 2cos²(x)-1
Hence, 2cos²(x)-1 is equal to cos(2x).
Answer:
Alberto is incorrect. Perimeter is 42 units.
Step-by-step explanation:
Given:
The vertices of the triangle are
Perimeter of a triangle of length and width is given as:
Here,
Distance between two points and is given as:
So, the length ST is,
Width TU is,
Therefore, the perimeter is given as:
Perimeter = units.
Hence, the perimeter written by Alberto is incorrect as perimeter is not 18 units bu 42 units.
Answer:
h = r
Step-by-step explanation:
x = (r-h)/y
h + x y = r
x = r/y - h/y
r = h
y ≠ 0
