Answer:

aₙ = a₁ + (n-1)d

where:

aₙ = nth term

a₁ = first term

d = common difference

The sequence 8,9,10,-10 is not an arithmetic sequence.

Given the triangle below, which of the following is a correct statement? Right triangle ABC with AB measuring 5, AC measuring 6,
Elanso [62]
Drawing a diagram to match this figure, BC would have to be the hypotenuse as it is the longest side of the triangle.  Angle A would have to be the right angle.  
For the first choice, \cot B = \frac{1}{ \tan B} &#10;\\ = \frac {1}{\frac {6}{5}}&#10;\\ = 1 \div \frac{6}{5} = \frac{1}{1} \div \frac{6}{5}&#10;\\ = \frac{1}{1} * \frac{5}{6} = \frac{5}{6}.  The first choice is not correct.
The second choice gives us \csc C= \frac{1}{ \sin C}= \frac{1}{\frac {5}{8}}&#10;\\ = 1 \div \frac{5}{8} = \frac{1}{1} \div \frac{5}{8}&#10;\\ = \frac{1}{1} * \frac{8}{5} = \frac{8}{5}.  The second choice is not correct either.
The third choice gives us

Can somebody explain this to me when 2du = 16xdx ???
tamaranim1 [39]
When you set u=4x^2+4, you end up with the differentials \mathrm du=8x\,\mathrm dx. Multiplying both sides by 2 gives 2\,\mathrm du=16x\,\mathrm dx.

Then the integral is

\displaystyle\int_0^1\frac{16x}{(4x^2+4)^2}\,\mathrm dx=\int_4^8\frac2{u^2}\,\mathrm du=-\frac2u\bigg|_{u=4}^{u=8}=-2\left(\frac18-\frac14\right)=\frac14

They all can be split up to 6 groups because 12+18=30 so each group will have 5 kids in it.
