c)
Scalar multiplication is a shortcut for repeated
addition of the same matrix.
Answer: 192 IS IRRATIONAL. I HOPE THIS ANSWER HELPS.
Step-by-step explanation:
It is an irrational number if it is not a perfect square. Since 192 is not a perfect square, it is an irrational number. This means that the answer to "the square root of 192?" will have an infinite number of decimals. The decimals will not terminate and you cannot make it into an exact fraction.
$25. 25 x 3 is 75. Plus the 100 is 175. 200 - 175 is $25
\left[x \right] = \left[ \frac{-1}{4}\right][x]=[4−1] = x*3 +3x*2+6) - (9x*2-5x+7
The answer is (-21, 13) for The second endpoint.
Let's start by calling the known endpoint L and the unknown K. We'll call the midpoint M. In order to find this, we must first note that to find a midpoint we need to take the average of the endpoints. To do this we add them together and then divide by 2. So, using that, we can write a formula and solve for each part of the k coordinates. We'll start with just x values.
(Kx + Lx)/2 = Mx
(Kx + 1)/2 = -10
Kx + 1 = -20
Kx = -21
And now we do the same thing for y values
(Ky + Ly)/2 = My
(Ky + 7)/2 = 10
Ky + 7 = 20
Ky = 13
This gives us the final point of (-21, 13)
