Explain how to determine which numbers must be excluded from the domain of a rational expression. Please provide an example with
Katarina [22]

Answer:

  • When we are having a rational expression i.e. a expression of the type:

\dfrac{f(x)}{g(x)}

Where f(x) and g(x) are polynomial functions.

Now the domain of this rational expression is whole of the real numbers except the points where the function g(x) will be zero.

Hence we have to exclude the points where the given denominator quantity is zero.

  • Let us consider an example as:

  Let R(x) denote the rational function as:

R(x)=\dfrac{x^2}{(x-2)(x-3)}

Now the domain of this rational function will be whole of the real line minus the points where the denominator is zero.

We know that (x-2)(x-3) is zero when x=2 or x=3.

Hence, the domain of R(x) is: R- {2,3}.

A rugby player passes the ball 7.75 m across the field, where it is caught at the same height as it left his hand. At what angle
prisoha [69]

<u>Answer-</u>

<em>At 15.91° the ball was thrown.</em>

<u>Solution-</u>

<em>In the question it is given that the ball was released and caught from the same height.</em>

We know that,

R=\frac{u^{2}\sin 2\Theta}{g}

Where,

R = Range of the projectile = 7.75 m,

u = Initial speed = 12 m/s

θ = Angle at which it was released

g = Acceleration due to gravity = 9.8 m/s²

Putting all the values,

\Rightarrow 7.75 = \frac{12^{2}\sin 2\Theta}{9.8}

\Rightarrow \sin 2\Theta=\frac{7.75 \times 9.8}{144} =0.5274

\Rightarrow 2\theta=\sin^{-1} 0.5274=31.83 \ or \ 148.17

\Rightarrow \theta=\frac{31.83}{2} \ or \ \frac{148.17}{2} =15.91 \ or \ 74.08

\Rightarrow \theta=15.91^{\circ} \ (smaller \ angle)

Solve the system
konstantin123 [22]
Use substitution. 

y = 2 - x and y = 4x + 7 can become

2 - x = 4x + 7

Now solve for x

-5 = 5x

-1 = x

Now plug -1 for x in either equation.

y = 2 - x -> y = 2 - (-1) -> y = 3
y = 4x + 7 -> y = 4*-1 + 7 -> y = -4 + 7 -> y = 3

So C) is the correct answer.
