1 answer:

3 0

Answer:

The segment connecting two corresponding points on the image and pre-image is a perpendicular bisector, so the line of reflection bisects the segment and the segment is perpendicular to the line of reflection, or intersects the line at a 90 degree angle. ... A transformation in which the image and pre-image are congruent.

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

Solve equation <br> √ 13x+27=√ 4x

natima [27]

What you have to do is rearrange the equation by subtracting what is on the right of the equal sign from both sides of the equation

so it would be 4*x-13*x-(27)=0
