Solve the following liner system.

Mathematics
1 answer:
blondinia [14]3 years ago
3 0
Answer: (6,13)

Work:
- set them equal to each other
2x + 1 = 1/2x + 10

- multiply both sides by 2 to get rid of fraction
4x + 2 = x + 20

- solve for x and you get x = 6

- plug in to solve for y
2(6) + 1 = y
13 = y

12. Let yo = O. Write parametric equations to represent the path of the ballsthrown by Sami and T'Aisha given the following cond
ira [324]

SOLUTION:

We want to write the x and y parametric equation for Sami and T'Aisha given their following data.

\begin{gathered} Sami:v_0=15\frac{ft}{s},\theta=35^o,y_0=5.4ft \\ T^{\prime}Aisha:v_0=19\frac{ft}{s},\theta=50^o,y_o=5.8ft \\ x_0=0 \end{gathered}

The parametric equations for x and y are given by;

\begin{gathered} x(t)=x_0+(v_0cos\theta)t \\ y(t)=y_0+(v_0sin\theta)t+0.5gt^2 \end{gathered}

Inserting, the values, we have; For Sami;

\begin{gathered} Sami: \\ x\left(t\right)=15cos35t, \\ y\left(t\right)=5.4+15sin35t-16t^2 \end{gathered}

For T'Aisha;

\begin{gathered} T^{\prime}Aisha: \\ x\left(t\right)=19cos50t, \\ y\left(t\right)=5.8+19sin50t-16t^2 \end{gathered}
