(1 pt) find a parametrization of the ellipse centered at the origin in the xy-plane that has major diameter 14 along the x-axis, minor diameter 10 along the y-axis, and is oriented counter-clockwise. your parametrization should make the point (7,0) correspond to t=0. use t as the parameter for all of your answers.

Step-by-step explanation:

The parametrization of an ellipse center at origin and counter-clockwise is given by the formulas:

Where “a” is the radius of the major axis along the x-axis and “b” is the radius of the minor axis along the y-axis. Since the major diameter along the x-axis is 14 then its radius is its half, thus a=7. Similarly, since the minor diameter along the y-axis is 10, then its radius is half of it, thus b=5

Therefore, the parametric equations for the ellipse become:

Notice at t=0 we get:

which satisfies that the parametrization at t=0 makes the point (7,0)

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm

sure i'm up for it
