We know, if we multiply a number x by its multiplicative inverse, the result is 1. So, 0.3 is the multiplicative inverse of 313.

Yes, 0.3 is the multiplicative inverse of 3 1/3 since 0.3 * 3/13 = 1.

Step-by-step explanation:

Multiplicative inverses, also called reciprocals, are two numbers whose product is 1.

What number multiplied by 3 1/3 equals 1?

3 1/3 * x = 1

10/3 x = 1

3/10 * 10/3 x = 1 * 3/10

x = 3/10 = 0.3

Yes, 0.3 is the multiplicative inverse of 3 1/3 since 0.3 * 3/13 = 1.

for the friend request.

when a figure, such as triangle (xyz) is reflected over the line y = x to create x'y'z' the x-coordinates and y-coordinates of the original image (pre-image) will be reversed for the image. (e.g., (x, y) > (y, x)) this means that the pre-image position of the x- and y-coordinates switch places which in turn provides a mirror like image of the original xyz.  

i notice that when i draw a line segment from x to x', that the points are parallel from each other -- they are exactly across from each other and do not intersect with any other points.  

yes, think i would see the same characteristic if you drew the line segment connecting y with the reflecting line and then y' with the reflecting line because of the essence of reflections. because it is a mirror image, each point was effected the same way which leads me to conclude that they same would apply to y and y'.

11.2

step-by-step explanation:

when doing tangent the tangent of the angle is equal to the opposite side from the angle over the adjacent side to the angle.

tan43 = x / 12

move 12 over by multiplying each side by 12

12tan43 = x

x = about 11.2
