Answer:

3x + 2y = 6        ⇒      (0,3)

-5x + y = -10       ⇒      (1,-5)

x - 4y = 8          ⇒      (4,-1)    

-6x - 5y = 30     ⇒      (0,-6)

Step-by-step explanation:

We are given four equation and four solution. We need to match the column

First we make table of equation and ordered pair

  Equation                     Ordered Pair

3x + 2y = 6                     (0,-6)

-5x + y = -10                    (0,3)

x - 4y = 8                        (4,-1)

-6x - 5y = 30                   (1,-5)

We find the solution of equation if point satisfy the equation.

In ordered pair we are given x-values 0,1,4 . Now we find y-value for each value of x

  Equation                        x=0             x=1              x=4            Solution

3x + 2y = 6                       y=3             y=3/2          y=-3              (0,3)

-5x + y = -10                      y=-10           y=-5            y=10             (1,-5)

x - 4y = 8                          y=-2            y=-7/4         y=-1              (4,-1)

-6x - 5y = 30                     y=-6           y=-36/5        y=-54/5       (0,-6)

Correct Match

3x + 2y = 6        ⇒      (0,3)

-5x + y = -10       ⇒      (1,-5)

x - 4y = 8          ⇒      (4,-1)    

-6x - 5y = 30     ⇒      (0,-6)

3x + 2y = 6....solution (0,3) 

-5x + y = -10...solution (1,-5)

x - 4y = 8...solution (4,-1)

-6x - 5y = 30...solution (0,-6)

A golfball is hit from the ground with an initial velocity of 200 ft/sec. The horizontal distance that the golfball will travel,
algol13

Answer:

The golfball launched with an initial velocity of 200ft/s will travel the maximum possible distance which is 1250 ft when it is hit at an angle of \pi/4.

Step-by-step explanation:

The formula from the maximum distance of a projectile with initial height h=0, is:

d(\theta)=\frac{v_i^2sin(2\theta)}{g}

Where v_i is the initial velocity.

In the closed interval method, the first step is to find the values of the function in the critical points in the interval which is [0, \pi/2]. The critical  points of the function are those who make d'(\theta)=0:

d(\theta)=\frac{v_i^2\sin(2\theta)}{g}\\d'(\theta)=\frac{v_i^2\cos(2\theta)}{g}*(2)\\d'(\theta)=\frac{2v_i^2\cos(2\theta)}{g}

d'(\theta)=0\\\frac{2v_i^2\cos(2\theta)}{g}=0\\\cos(2\theta)=0\\2\theta=\pi/2,3\pi/2,5\pi/2,...\\\theta=\pi/4,3\pi/4,5\pi/4,...

The critical value inside the interval is \pi/4.

d(\theta)=\frac{v_i^2sin(2\theta)}{g}\\d(\pi/4)=\frac{v_i^2sin(2(\pi/4))}{g}\\d(\pi/4)=\frac{v_i^2sin(\pi/2)}{g}\\d(\pi/4)=\frac{v_i^2(1)}{g}\\d(\pi/4)=\frac{(200)^2}{32}\\d(\pi/4)=\frac{40000}{32}\\d(\pi/4)=1250ft

The second step is to find the values of the function at the endpoints of the interval:

d(\theta)=\frac{v_i^2sin(2\theta)}{g}\\\theta=0\\d(0)=\frac{v_i^2sin(2(0))}{g}\\d(0)=\frac{v_i^2(0)}{g}=0ft\\\theta=\pi/2\\d(\pi/2)=\frac{v_i^2sin(2(\pi/2))}{g}\\d(\pi/2)=\frac{v_i^2sin(\pi)}{g}\\d(\pi/2)=\frac{v_i^2(0)}{g}=0ft

The biggest value of f is gived by \pi/4, therefore \pi/4 is the absolute maximum.

In the context of the problem, the golfball launched with an initial velocity of 200ft/s will travel the maximum possible distance which is 1250 ft when it is hit at an angle of \pi/4.
