Undefined at the x- intercepts, +1 and -1. (apex)

Answer:

Hence, the values of x for which the expression is not defined is equal to 1 or -1.

Step-by-step explanation:

We are asked to find for which values of x is the rational expression:

\dfrac{x+5}{3x^2-3} is undefined.

We know that a rational expression is undefined when the denominator term is equal to zero.

Hence, we could represent the algebraic expression as:

\dfrac{x+5}{3x^2-3}=\dfrac{x+5}{3(x^2-1)}\\\\\dfrac{x+5}{3x^2-3}=\dfrac{x+5}{3(x-1)(x+1)}

Hence, clearly from the expression we could observe that:

the expression is not defined when x=1 or x=-1.

( since the denominator will be zero if x receives any of the above two values or both)

Hence, the values of x for which the expression is not defined is equal to 1 or -1.

Find all polar coordinates of point P = (9, 75°).
zubka84 [21]

Answer:

1) (9, 75+360n)

2) (−9, 255+360n)

Step-by-step explanation:

(9, 75) is same as (9, 75 + 360)

so it would be (9, 435)

It can also be expressed as (-9, 75 + 180 degrees)

so (-9,255) degrees

In general, (9,75+360 n) for n≥0 represents half of the possible ways of representing the point : (9,75)

Find the value of X round your number to the nearest tenths<br><br><br> Explain it please
Anarel [89]

In this case, we must use trigonometry to find the value of x:

        tan(\alpha )=\frac{side-opposite-angle}{side-beside-angle} \\tan(70) = \frac{x}{3} \\3*tan(70) = x\\x = 3*tan(70)\\x = 8.24

Thus the value of x rounded to the nearest tenth is <u>8.2</u>

<u></u>

Hope that helps!
