2. Vectors u and v are given by: u=5i-4j+ pk v=2i+tj-3k (a) Express p in terms of t when u and v are perpendicular. ​
Sindrei [870]

If u and v are perpendicular, then their dot product is zero:

\vec u \cdot \vec v = (5\,\vec\imath-4\,\vec\jmath+p\,\vec k) \cdot (2\,\vec\imath+t\,\vec\jmath - 3\,\vec k) = 10 - 4t - 3p = 0

Solve for p :

10 - 4t - 3p = 0

3p = 10 - 4t

\boxed{p = \dfrac{10-4t}3}

If $500 is put into a savings account at 9% interest compounded continuously, how much will it be worth at the end of 3 years? H
Digiron [165]

Answer:

$654.98

Around 7.7 years

Step-by-step explanation:

Value = P × e^(rt)

= 500 × e^(0.09×3)

= 500 × e^(0.27)

= 654.9822254

Double: 500 × 2 = 1000

1000 = 500 × e^(0.09t)

e^(0.09t) = 2

Use ln both sides

0.09t × lne = ln2

t = ln2 ÷ 0.09

t = 7.70163543
