Answer:

For x = 0 and x=2, the expression is undefined.

Step-by-step explanation:

We have been given that

V = (5-x) cubic feet

w = x feet

l = (x-2) feet

And the height is given by the expression

h=\frac{5-x}{x(x-2)}

Now, we know that a rational function is not defined if the denominator is zero. Hence, in order to the expression for height to be defined, we have

x(x-2)\new 0\\x\neq 0,2

Hence, for x = 0 and x=2, the expression is undefined.

A rational expression is undefined when the denominator is zero.
V=\dfrac{5-x}{x(x-2)}
is undefined when x=0 or x=2.

Find the value of x. (Type an integer or decimal.)
SOVA2 [1]

Answer:

70

Step-by-step explanation:

An angle formed by 2 tangent lines is equal to one half the measure of the major arc minus the measure of the minor arc.

we are given the minor arc ( 110 ) however we are not given the major arc.

Because circles make a 360 degree rotation we can find the major arc by subtracting the measure of the minor arc from 360

Thus, major arc = 360 - 110 = 250

Now that we have identified the major and minor arc we can find x

Recall that x = 1/2 ( major arc - minor arc )

Thus, x = 1/2 ( 250 - 110 )

250 - 110 = 140

140 / 2 = 70

Hence, x = 70

Hey there!

Okay let's get cracking :D

The equation is....  (2x/3) - 6 = 9

2x/3 = 15
2x = 45

Point A is at (3, 2.5) and point B is at (3, 1.4) on a coordinate grid. The distance between the two points is ____. Input numbe
andriy [413]
The points have the same x-coordinate, so they lie on a horizontal line. The distance between them is the difference between their y-coordinates.

2.5 - 1.4 = 1.1

The distance between the two points is 1.1
