Mrrafil [7]

7 + 1.25t = 43.25 <== ur equation
1.25t = 43.25 - 7
1.25t = 36.25
t = 36.25 / 1.25
t = 29 <== he was jumping for 29 minutes

Describe the motion of a particle with position (x, y) as t varies in the given interval. (For each answer, enter an ordered pai

DerKrebs [107]

Answer:

The motion of the particle describes an ellipse.

Step-by-step explanation:

The characteristics of the motion of the particle is derived by eliminating $t$ in the parametric expressions. Since both expressions are based on trigonometric functions, we proceed to use the following trigonometric identity:

$\cos^{2} t + \sin^{2} t = 1$ (1)

Where:

$\cos t = \frac{y-3}{2}$ (2)

$\sin t = x - 1$ (3)

By (2) and (3) in (1):

$\left(\frac{y-3}{2} \right)^{2} + (x-1)^{2} = 1$

$\frac{(x-1)^{2}}{1}+\frac{(y-3)^{2}}{4} = 1$ (4)

The motion of the particle describes an ellipse.

What type of triangle is formed by joining the points D(7, 3), E(8, 1), and

KiRa [710]

D(7, 3), E(8, 1), and F(4, -1)

We calculate the squared distances between the points:

$DE^2 = 1^2 + 2^2 = 5$

$EF^2=4^2+2^2=20$

$DF^2=3^2+4^2=25$

Since $DF^2=DE^2+EF^2$ we have a right triangle with hypotenuse DF.
