You basically have to add the like terms together.
7k+8k & 3f+15f
=15k. = 18f
Now your just left with 15k+18f because you can’t add them because they don’t have like terms
So they answer is 15k+18f
Hope this helped!

This is a question on my partial fractions homework, but no matter what I try I can't figure it out..

Ierofanga [76]

$\dfrac{x^2+x+1}{(x+1)^2(x+2)}=\dfrac{a_1x+a_0}{(x+1)^2}+\dfrac b{x+2}$
$\implies\dfrac{x^2+x+1}{(x+1)^2(x+2)}=\dfrac{(a_1x+a_0)(x+2)+b(x+1)^2}{(x+1)^2(x+2)}$
$\implies x^2+x+1=(a_1+b)x^2+(2a_1+a_0+2b)x+(2a_0+b)$
$\implies\begin{cases}a_1+b=1\\2a_1+a_0+2b=1\\2a_0+b=1\end{cases}\implies a_1=-2,a_0=-1,b=3$

So you have

$\displaystyle\int_0^2\frac{x^2+x+1}{(x+1)^2(x+2)}\,\mathrm dx=-2\int_0^2\frac x{(x+1)^2}\,\mathrm dx-\int_0^2\frac{\mathrm dx}{(x+1)^2}+3\int_0^2\frac{\mathrm dx}{x+2}$
$=\displaystyle-2\int_1^3\dfrac{x-1}{x^2}\,\mathrm dx-\int_0^2\frac{\mathrm dx}{(x+1)^2}+3\int_0^2\frac{\mathrm dx}{x+2}$

where in the first integral we substitute $x\mapsto x+1$ .

$=\displaystyle-2\int_1^3\left(\frac1x-\frac1{x^2}\right)\,\mathrm dx-\frac1{1+x}\bigg|_{x=0}^{x=2}+3\ln|x+2|\bigg|_{x=0}^{x=2}$
$=-2\left(\ln|x|+\dfrac1x\right)\bigg|_{x=1}^{x=3}-\dfrac23+3(\ln4-\ln2)$
$=-2\left(\ln3+\dfrac13-1\right)-\dfrac23+3\ln2$
$=\dfrac23+\ln\dfrac89$

A ladder 15 feet long leans against the top of a structure at a 60 degree angle to the ground. What is the height of the buildin

Goshia [24]

Answer:

height of the building is 12.99 feet.

Step-by-step explanation:

given, try to analyse:

ladder 15 feet long.
60 degree angle to the ground.

the height of the building is opposite to the angle 60° and given hypotenuse, the ladder of 15 feet long.

using sine rule:

$sin(x) = \frac{opposite}{hypotenuse}$

$sin(60) = \frac{opposite}{15}$

$opposite = sin(60) *15$

$opposite = 12.99feet$

Therefore the height of the building is 12.99 feet.

What Is a Liberal Arts College?

While many colleges and universities grant liberal arts degrees, a liberal arts college offers a focused liberal arts education.
These colleges generally emphasize small class sizes and a curriculum centered on the humanities, arts, social sciences, and natural sciences.

What's the difference between a liberal arts college and a regular college?

Most liberal arts colleges do not offer graduate school programs, unlike other universities.
They also tend to have small campuses and class sizes; in fact, many classes have fewer than 20 students.
Evans says some students find comfort in the sense of community that these more intimate settings can create.
