Vector V is in standard position and makes an angle of 50° with the positive x-axis. Its magnitude is 18. Write V in component f

Umnica [9.8K]

Answer:

11.57 units east, 13.79 units upwards

11.57i + 13.79j

Step-by-step explanation:

V = 18 units at an angle of 50° to the positive x-axis

In component Form, this is how each component is calculated

a = 18cos50° = 11.57 units east

b = 18sin50° = 13.79 units upwards

check if your answer is correct

$\sqrt{11.57^{2} +13.79^{2} } = 18.0$

In vector component form ai + bj = 11.57i + 13.79j

If you bought something for $372.60 including an 8% tax, what was the price before the tax?

Dvinal [7]

Answer:

$345

Step-by-step explanation:

Let the price before tax be x, then we have:

x + 8% = 372.60
x + 0.08x = 372.60
1.08x = 372.60
x = 372.60 / 1.08
x = 345

The initial price was $345
