Integral of 11 ln(cube root(x)) dx?

Leno4ka [110]

$\bf \int [11\ ln\left( \sqrt[3]{x} \right)]dx\qquad 
\begin{cases}
ln\left( \sqrt[3]{x} \right)\implies ln\left( x^{\frac{1}{3}} \right)
\\ \quad \\
\frac{1}{3}ln(x)
\end{cases}\qquad thus
\\ \quad \\\\ \quad \\
\int [11\ ln\left( \sqrt[3]{x} \right)]dx\implies \int[11\cdot \frac{1}{3}ln(x)]dx\impliedby \textit{scalars to the left}
\\ \quad \\
11\cdot \frac{1}{3}\int[ln(x)]dx\implies \cfrac{11}{3}\int[ln(x)]dx$

and I'm pretty sure you know what that is

Roger can run one mile in 18 minutes. jeff can run one mile in 15 minutes. if jeff gives roger a 1 minute head start, how long w

gladu [14]

Alright, lets get started.

Roger can run one mile in 18 minutes.

Jeff can run one mile in 15 minutes.

Suppose in x minutes, they both will catch up.

Roger runs in 18 minutes = 1 mile

So, Roger will run in 1 minute = $\frac{1}{18}$ miles

So, Roger will run in x minutes = $\frac{x}{18}$ miles

Jeff runs in 15 minues = 1 mile

So, Jeff will run in 1 minute = $\frac{1}{15}$ mile

As Jeff gives roger a 1 minute head start, means Jeff will have x-1 minute time to run

So, Jeff will run in (x-1) minute = $\frac{x-1}{15}$

As both are cathing up means they both runs same distance, means

$\frac{x}{18} =\frac{x-1}{15}$

Cross Multiplying

$15 x = 18x - 18$

$3 x = 18$

x = 6 minutes

So for calculating distance = $speed * time$

Distance = $\frac{1}{18} *6 = \frac{1}{3}$ miles

It means it will take 1/3 or 0.33 miles before jeff catches up to roger. : Answer

Hope it will help :)

Ok let’s solve it

5(x-2)^2-20=0

first let’s foil (x-2)

5(x^2-4x+4) -20=0

now distribute the 5

5x^2 -20x +20 -20 = 0

combine like terms

5x^2-20x=0

take the gcf

5x(x-4)=0

x=0, 4

solutions are (4,0) and (2, -20) because the original vertex form a(x-h)^2+k

The average number of hours of sleep per night was 9.46 hours for a sample of 104 five to seven year-old children. The number 9.

alexgriva [62]

Answer:

Statistic

Step-by-step explanation:

Since, a characteristic of a sample is called statistic. It is used to estimate the value of a population parameter and can be computed from the sample.

Here, the sample is 104 children,

For which the average number of hours of sleep per night was 9.46 hours,

∵ 9.46 is the number that can be computed from the sample of 97 children.

Hence, the number 9.46 is a Statistic
