Answer:
(3.2, 0.6)
Step-by-step explanation:
means a translation of (x, y) → (x - 5.2, y + 1.4)
Suppose X has coordinates (a, b), after the translation is applied, X' has coordinates (a - 5.2, b + 1.4). X' is located at (-2, 2), therefore:
a - 5.2 = -2
a = -2 + 5.2
a = 3.2
b + 1.4 = 2
b = 2 - 1.4
b = 0.6
Cos M = 40/76
Cos M = 10/19
M = 58 degrees

Answer:
B) 72
Step-by-step explanation:
The n-th term of an arithmetic sequence An = a1 + (n - 1) d
Given :
a28 = 423/4 and d = 5/4
So
a28 = a1 + (28 - 1)5/4
Now plug in a28 = 423/4
423/4 = a1 + 27(5/4)
a1 = 423/4 - 27(5/4)
= 423/4 - 135/4
a1 = (423-135)/4
a1 = 288/4
a1 = 72
