Answer:
Step-by-step explanation:
73/2 : 117/4
=73/2 . 4/117
=146/117
=1.247
Answer:
The answer is D
Step-by-step explanation:
You multiply by 2 19 x 2 = 38 38 x 2 = 76 76 x 2 = 152
then 152 x 2 = D 304
P = principal (initial amount), r = rate of interest, and t = time
So, A = 3000(1+0.025)^4
Answer: $3,311.44 (approximately)
Answer:
negative
Step-by-step explanation:
positive * positive = positive
negative * positive = negative
negative * positive = negative
U = - 4 i + 1 j
v = 4 i + 1 j
| u | = √ (-4)² + 1² = √ 17
| v | = √4² + 1² = √ 17
| u + v | = √(u + v)²=
= √( u² + 2 u v + v² )= ...
cos ( u, v ) = (-16+1) / (|u| |v|) = -15/17
...= √(17 + 2 · √17 · √17 · ( -15/17) +17) =
= √ 34 - 30 = √ 4 = 2
