Point (a,a) lies on the graph of the equation 3y = 2x -4 find the value of a

Substituting (x, y) with (a, a), since we have:

3a=2a-4, which means that 3a-2a=-4, that is a=-4.

So, the point is (-4, -4).

Remark: a point which lies in the graph of an equation is a solution of that equation. So x=a, y=a satisfies the equation <span> 3y = 2x -4, which makes our substitution legitimate.

Answer: </span>(-4, -4).

A clown is shot out of cannon with a velocity of 200 feet per second at an angle of 24°

Nadusha1986 [10]

Answer:

Vertical component of velocity is $81.35 ft/sec.$

Horizontal component of velocity is $182.6 ft/sec$ .

Step-by-step explanation:

Horizontal component of velocity is defined as:

$v_{x} = v\times cos\theta$

Vertical component of velocity is defined as:

$v_{y} = v\times sin\theta$

Where $v_{x} , v_{y}$ are the horizontal and vertical components of velocity.

$v$ is the actual velocity and

$\theta$ is the angle with horizontal axis at which the object was thrown.

Here, we are provided with the following:

$v = 200 ft/sec$

$\theta = 24^\circ$

$v_{x} = 200 \times cos24^\circ\\\Rightarrow 200 \times 0.913\\\Rightarrow v_{x} = 182.6 ft/sec$

$v_{y} = 200 \times sin24^\circ\\\Rightarrow 200 \times 0.407\\\Rightarrow v_{y} = 81.35 ft/sec$

So, Vertical component of velocity is $81.35 ft/sec.$

Horizontal component of velocity is $182.6 ft/sec$ .
