Answer:

390 centimeters

Step-by-step explanation:

The length of a piece of fabric = 3.9 meters

We have to convert 3.9 meters in centimeters.

1 meter = 100 centimeters

Now we will multiply the length of 3.9 meters to 100 centimeters.

3.9 meters = 3.9 × 100

= 390 centimeters

This length in centimeters = 390 centimeters.

seropon [69]

Answer:

3125 cm

Step-by-step explanation:

The distance between two villages is 0.625 km. Find the length in centimetres between the two villages on a map with a scale of 1:5000.

We are given the scale of

1: 5000

This means

1 km = 5000 cm

Hence:

1 km = 5000cm

0.625 km = x cm

Cross Multiply

x cm = 0.625 × 5000 cm

x cm = 3125 cm

Therefore, the length in centimetres between the two villages is 3125cm

To produce a box plot, we need the lowest and highest value from the data set. We also need the lower quartile ( $Q_{1}$ ), median ( $Q_{2}$ ), and upper quartile ( $Q_{3}$ ).

All these data and the box plot is shown in the diagram below

Divide $-11 \frac{1}{5}$ by 5. Or multiply it by 1/5.

You get - 56/25 or $-2 \frac{6}{25}$ pounds per month.

Determine whether the improper integral converges or diverges, and find the value of each that converges.

Temka [501]

Answer:

It diverges.

Step-by-step explanation:

We are given the inetegral: $\int\limits^{\infty}_2 \frac{1}{x} (\ln x)^2 dx$

$\int\limits^{\infty}_2 \frac{1}{x} (\ln x)^2 dx=\int\limits^{\infty}_2 (\ln x)^2 d(\ln x)=\\\\=\lim_{t \to \infty} \int\limits^t_2 (\ln x)^2d(\ln x)=\lim_{t \to \infty} \frac{(\ln t)^3}{3} |^t_2=\infty-\frac{(\ln 2)^3}{3} =\infty$

So it is divergent.
