D is most likely right. Basically, I would turn them into decimals and divide using a graphing calculator.
V=<12,5>
Magnitude
|v| = sqrt(12^2+5^2) = 13
Direction
theta
= atan2(5,12)
= atan(5/12)
= 22.62 degrees
Answer:
b = 3 or -3 i suppose
Step-by-step explanation:
3.4×10⁻¹⁴ × 1.8×10²⁸
= (3.4 x 1.8) x 10⁽⁻¹⁴⁺²⁸⁾
= 6.12 x 10¹⁴
Answer is A.
Hope it helps!
The final point should end up at (-11,-4)
