In the first row of an augmented matrix, we put all the slope constants there.
[3/4
[-8
We have no terms for the next column, so we'll put 1's there.
[3/4 1
[-8 1
Finally, we put the y intercepts in the last column.
[3/4 1 | -6]
[-8 1 | 2] (Choice B, Choice 2)

From what I remember, hear is an example cuz idk how to really explain... there are 3 yellow cubes, 4 green, and 2 blue cubes all in one bag. You add the total number of cubes (3+4+2=9) let’s say I want to know what is the probability of grabbing a yellow cube. There is a total of 3 yellow cubes in the bag so just put that over 9 in a fraction (3/9) so that would be your fraction probability and if you want a percentage you just divide the numerator (3) by the denominator (9) which would be .33 so there is a 33% chance of grabbing a yellow cube. I’m so sorry if this didn’t help x-x
Answer:
a) clockwise sense
b) x² + y² = 1
c) y ∈ [0,1]
Step-by-step explanation:
a) x = cos (t) y = -sin (t)
for t ∈ [ 0 , 2π ]
for t = 0 point P is x = cos (0) = 1 y = -sin (0) y = 0
The point is on the x axis
Now let´s see what happens for t = π/4
x = cos (π/4) x = √2/2 and y = - sin (π/4) y = - √2/2
Note π/4 is 45°
The coordinates of the new point P ´(t = π/4) are in the fourth quadrant
that means the point is moving clockwise sense.
b) x = cos(t)
y = -sin(t)
Squaring on both sides of each equation we get:
x² = cos²t
y² = sin²(t)
Adding side by side
x² + y² = cos²t + sin²t
x² + y² = 1
Values for y are y ( 0 , 1)
