jose is hiking a trail that is 2 /4 miles long. he hikes 1 5/8 miles before resting how much farther does he have left

Yanka [14]

The number of miles that Jose will have left after resting will be 1 1/8 miles.

Total distance to be covered = 2 3/4 miles

Distance traveled = 1 5/8 miles

Therefore, in order to get the distance that's left for Jose to complete his journey, we've to subtract the distance traveled from the total distance and this will be:

= 2 3/4 - 1 5/8

= 2 6/8 - 1 5/8

= 1 1/8

Therefore, he has 1 1/8 miles left to travel.

An acute angle θ is in a right triangle with sin θ = six sevenths. What is the value of cot θ?

inysia [295]

$\sin \theta =\dfrac{6}{7}\\
\cot \theta=\dfrac{x}{6}\\
x^2+6^2=7^2\\
x^2=49-36\\
x^2=13\\
x=\sqrt{13}\\
\boxed{\cot \theta =\dfrac{\sqrt{13}}{6}}$

Integrala x la a treia ori ln la a doua dx va rog

Studentka2010 [4]

I don't speak Romanian, but the closest translation for this suggests you're trying to compute

$\displaystyle \int x^3 \ln(x)^2 \, dx$

Integrate by parts:

$\displaystyle \int x^3 \ln(x)^2 \, dx = uv - \int v \, du$

where

u = ln(x)² ⇒ du = 2 ln(x)/x dx

dv = x³ dx ⇒ v = 1/4 x⁴

$\implies \displaystyle \int x^3 \ln(x)^2 \, dx = \frac14 x^4 \ln(x)^2 - \frac12 \int x^3 \ln(x) \, dx$

Integrate by parts again:

$\displaystyle \int x^3 \ln(x) \, dx = u'v' - \int v' du'$

where

u' = ln(x) ⇒ du' = dx/x

dv' = x³ dx ⇒ v' = 1/4 x⁴

$\implies \displaystyle \int x^3 \ln(x) \, dx = \frac14 x^4 \ln(x) - \frac14 \int x^3 \, dx$

So, we have

$\displaystyle \int x^3 \ln(x)^2 \, dx = \frac14 x^4 \ln(x)^2 - \frac12 \left(\frac14 x^4 \ln(x) - \frac14 \int x^3 \, dx \right)$

$\displaystyle \int x^3 \ln(x)^2 \, dx = \frac14 x^4 \ln(x)^2 - \frac18 x^4 \ln(x) + \frac18 \int x^3 \, dx$

$\displaystyle \int x^3 \ln(x)^2 \, dx = \frac14 x^4 \ln(x)^2 - \frac18 x^4 \ln(x) + \frac18 \left(\frac14 x^4\right) + C$

$\displaystyle \int x^3 \ln(x)^2 \, dx = \frac14 x^4 \ln(x)^2 - \frac18 x^4 \ln(x) + \frac1{32} x^4 + C$

$\boxed{\displaystyle \int x^3 \ln(x)^2 \, dx = \frac1{32} x^4 \left(8\ln(x)^2 - 4\ln(x) + 1\right) + C}$

chubhunter [2.5K]

$\bf \textit{lateral surface area of a cylinder}\\\\
A=2\pi r h\qquad \begin{cases}
r=radius\\
h=height\\
-----\\
r=2.4\\
h=11
\end{cases}\implies A=2\pi (2.4)(11)\implies A=52.8\pi$

2x + 5 > 9 and 5x less than or equal to 30

tatuchka [14]

2x + 5 > 9
so 2x > 9-5
2x > 4
x > 2

5x <= 30
x <= 6

answer is 2 < x <= 6

or interval notation it is (2, 6]
