Answer:

(x, y) -----> (-x, y).

(Please mark as brainliest)

Step-by-step explanation:

We are given to write a rule that describes a transformation across the y-axis. We know that if a point is reflected across the y-axis, then the sign before the x co-ordinate changes. That is, if the point (x, y) is reflected (transformed) across the y-axis, then its new co-ordinates will be (-x, y).

Thus, the required transformation rule is given by (x, y) -----> (-x, y).

In the diagram, point X is the centroid. If<br> EX=8, what is the length of XC ?

Phoenix [80]

Answer:

Step-by-step explanation:

If X is the centroid that means that EC is a median along with the other lines that intersect inside the triangle. Medians drawn from a triangle have a special rule; this rule is that all medians have a 2:1 ratio between the different sections of one median. For example, EC is one median with the two sections XC and EX. Therefore XC and EX have a 2:1, with the 2 representing the longer section closest to the vertex. This means that XC is double EX, so to find XC simply double EX measurement, which is 8. So XC must equal 16.

if you deposit $8000 into an account paying 9% annual interest compunded semi anually how long will it take for your money to do

Anna007 [38]

Answer:

7.87 years

Step-by-step explanation:

#First we determine the effective annual rate based on the 9% compounded semi annual;

$i_m=(1+i/m)^m-1\\\\=(1+0.09/2)^2-1\\\\=0.09203$
