Your opening balance this month was $1,664.00. In the last thirty days you made the following purchases: $27.35, $54.15, and $12

Viktor [21]

Answer:

$1661.41875

Step-by-step explanation:

Since you purchased the following

$27.35,$54.15,$125

So let's add up

27.35+54.15+125

206.5

So let's determine the interest

1.25% of 206.5

1.25/100 ×206

258.125/100

2.58125

So we will have to deduct 2.58125 from the initial amount

1664-2.58125

1661.41875

So the amount left is $1661.41875

The components of a vector are Ax = –10 units and Ay = 8 units. What angle does this vector make with the positive x axis? g

Mandarinka [93]

Answer:

This vector make an angle of 141° with the positive x axis

Step-by-step explanation:

Refer the attached figure

Components of vector :

$A_x=-10 \\A_y = 8$

We are supposed to find What angle does this vector make with the positive x axis

$tan \theta =\frac{A_y}{A_x}\\tan \theta =\frac{8}{-10}\\\theta =tan^{-1}(\frac{8}{-10})\\\theta =tan^{-1}(\frac{8}{-10})=-38.65^{\circ}$

Now ,

$\alpha = 180-38.65=141.35^{\circ}$

So, this vector make an angle of 141° with the positive x axis
