Artyom0805 [142]

Answer: $\$ 6371.12$

Step-by-step explanation:

We have the following data:

Bianka's credit line = $8,000

Bianka's previous balance = $567.91

Payments = $1,200

Total purchases = $986.79

Finance charge = $10.00

Well, firstly we have to find Bianka's current balance, which is her previous balance minus all her payments, purchases and charges:

Bianka's current balance = Bianka's previous balance - (Payments + Total purchases + Finance charge)

Bianka's current balance = $567.91 - ($1,200 + $986.79 + $10.00)

Bianka's current balance = -$1628.88

Now we can find her available credit, which is her credit line with the addition of the calculated current balance:

Bianka's available credit = Bianka's credit line + Bianka's current balance

Bianka's available credit = $8,000 + (-$1628.88)

Finally we have:

Bianka's available credit = $6371.12

(b) Find the angle between u and v to the nearest degree.

yulyashka [42]

Question 1 (b)

$u \cdot v=11\\\\|u|=\sqrt{3^{2}+(-1)^{2}}=\sqrt{10}\\\\|v|=\sqrt{4^{2}+1^{2}}=\sqrt{17}$

So,

$\cos \theta=\frac{11}{\sqrt{10}\sqrt{17}}\\\\\theta=\cos^{-1} \left(\frac{11}{\sqrt{10}\sqrt{17}} \right) \approx \boxed{32^{\circ}}$

Question 2 (b)

$u \cdot v=22\\\\|u|=\sqrt{5^{2}+2^{2}}=\sqrt{29}\\\\|v|=\sqrt{4^{2}+1^{2}}=\sqrt{17}$

So,

$\cos \theta=\frac{22}{\sqrt{29}\sqrt{17}}\\\\\theta=\cos^{-1} \left(\frac{22}{\sqrt{29}\sqrt{17}} \right) \approx \boxed{8^{\circ}}$
