Answer:
The required vector parametric equation is given as:
r(t) = <3cost, 3sint>
For 0 ≤ t ≤ 2π
Step-by-step explanation:
Given that
f(x, y) = <2y, -sin(y)>
Since C is a cirlce centered at the origin (0, 0), with radius r = 3, it takes the form
(x - 0)² + (y - 0)² = r²
Which is
x² + y² = 9
Because
cos²β + sin²β = 1
and we want to find a vector parametric equations r(t) for the circle C that starts at the point (3, 0), we can write
x = 3cosβ
y = 3sinβ
So that
x² + y² = 3²cos²β + 3²sin²β
= 9(cos²β + sin²β) = 9
That is
x² + y² = 9
The vector parametric equation r(t) is therefore given as
r(t) = <x(t), y(t)>
= <3cost, 3sint>
For 0 ≤ t ≤ 2π
Answer:
0.714 free throws.
Step-by-step explanation:
Anna made 20 out of 28 free throws.
Free-throw average = 
= 0.7142857143 free throws.
This equals 0.714 free throws (answer rounded up to the nearest thousandths)
300 is 10 times as much as 30.
because if you do 30 x 10 you get 300
The formula for calculating the perimeter of the parallelogram is p/2-b=c.
The formula for calculating the perimeter of a parallelogram with sides b and c, for c.
<h3>
What is the perimeter of the parallelogram?</h3>
The perimeter of a parallelogram is the total distance enclosed by its boundary. Since the parallelogram is a type of quadrilateral, thus it has four sides.
Substracting 2b on both side
p = 2b+2c
-2b -2b
p -2b =2c
divide both sides by 2
p/2 -b =c
Therefore we get the formula for calculating the perimeter of the parallelogram is p/2-b=c.

Answer:
Reflexive
Step-by-step explanation:
When a=a, it is called the reflexive property
a=b then b=a is the symmetric property
a=b b=c then a=c is the transitive property
