Answer:
Step-by-step explanation:
When talking about reflection, we usually mean reflecting across a line, or axis. Reflecting a shape means looking at the mirror image on the other side of the axis. Consider the point (x,y), if you reflect this point across the y-axis you should multiply the x-coordinate by -1, so you get:
For triangle ABC we have:
Therefore, the reflecting points are:
Both the original triangle and the reflected one are shown below.
Answer:
To the power 3 means cube.
Whenever you cube an even number it is a multiple of 8.
Whenever an exponent is used on 4, the number is always a square.
Answer: C. 324 units^3
Step-by-step explanation:
The answer is option b because by substituting the values corresponding to x = -2 and x = -3 then the result of the equation is zero. Therefore, it is shown that for this equation both roots of the polynomial are correct.
The probability to choose letter n is
. After drawing letter n there left 25 letters and the probability to choose the letter w is
. After drawing two letters n and w there left 24 letters and then the probability to choose letter b is
. After drawing three letters n, w and b there left 23 letters, so the probability to choose letter t is
.
Using the product rule for probabilities, you can obtain that
.
