Answer:
Missing x:0
Missing y:1
Hence, option b is correct.
Step-by-step explanation:
Given the table
x y
-9 3
-6 2
-3 missing
missing 0
As we know that the linear function has a constant common difference between the x values and y values.
From the table, it is clear that the x values have the same common difference, and the consecutive x values are separated by -3.
i.e. -9-(-6)=-3
-6-(-3)=-3
So the missing x value will be:
-3-(x)=-3
-3-(0)=-3
Therefore, the missing x value wil be: 0
From the table, it is clear that the x values have the same common difference, and the consecutive x values are separated by 1.
i.e.
3-2=1
2-y=1
y=1
Therefore, the missing y-value will be 1.
Therefore,
Missing x:0
Missing y:1
Hence, option b is correct.
Answer:
7x(y - 7)(y + 7)
Step-by-step explanation:
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)
10% of 76.5 is 7.65
x3 to get 30% so 22.95
Take this away from original because discount
76.5-22.95=$53.55
