Answer:
B. 5, 20, 80, 320.
Step-by-step explanation:
f(1) = 5
After the first rem, each term id 4 times the previous term, so:
f(2) = 4f(1) = 4*5 = 20.
f(3) = 4f(2) = *20 = 80
f(4) = 4(f3) = 4*80 = 320.
In the general case, it is (x, y+3), where y = f(x).
Answer:
37°
Step-by-step explanation:
By definition all internal angles of a triangle add up to 180°
Hence,
98° + 45° + x = 180°
x = 180° - 98° - 45° = 37°
I think it’s always because the absolute value is always positive.
