At which value(s) is the expression 1/x undefined?

1 answer:

When a function/expression is "undefined", their denominator would equal to zero.

When would f(x)=1/0? When x=0!

Therefore, when x=0, the function would become undefined.

If you have a more complex function such as 1/2x+3 and you want to find the point it becomes undefined,

Make 2x+3=0 and find x.

2x+3=0
2x=-3
x=-3/2 (at this point it becomes undefined)

Hope I helped :)

A circle with area 36pi has a sector with a central angle of 48°. what is the area of the sector?

Elza [17]

Answer:4.8π

Step-by-step explanation:

Φ=48°

Area of circle=36π

Area of circle=π x r^2

36π=πr^2

Dividing both sides by π we get

r^2=36π/π

r^2=36

Take them square root of both sides

√(r^2)=√(36)

r=6

Area of sector=Φ/360 x π x r x r

Area of sector=48/360 x π x 6 x 6

Area of sector=(48xπx6x6)/360

Area of sector=1728π/360

Area of sector=4.8π

The dot plot showed the number of flowers on a rosebush: 18, 18, 18, 18, 20, 20, 22, 23 The number 19 is used to summarize the d

Darya [45]

Answer:

19 measures the median

Step-by-step explanation:

The dot plot is not shown, but the question can still be answered.

We have:

$Samples: 18, 18, 18, 18, 20, 20, 22, 23$

$n = 8$

Calculate the median position using:

$Median = \frac{n + 1}{2}th$

$Median = \frac{8 + 1}{2}th$

$Median = \frac{9}{2}th$

$Median = 4.5th$

4.5th means the median is the mean of the 4th and 5th item.

We have:

$4th = 18$

$5th = 20$

So:

$Median = \frac{18 + 20}{2}$

$Median = \frac{38}{2}$

$Median = 19$
