Answer:

What is the difference between constructing a square and constructing a regular hexagon?

The diameter of the circle is used for the square construction, but the radius of the circle is used for the regular hexagon construction.

The radius of the circle is used for the square construction, but the diameter of the circle is used for the regular hexagon construction.

The square will need two arcs along the circle, but the hexagon will need two arcs above and two arcs below the diameter of the circle.

The square will need six arcs along the circle, but the hexagon will need two arcs above and two arcs below the diameter of the circle.

Answer:

this is what I found "The bearing of a point is the number of degrees in the angle measured in a clockwise direction from the north line to the line joining the centre of the compass with the point. A bearing is used to represent the direction of one point relative to another point."

I can't really make sense of it though...

What is the sum of the finite arithmetic series?

mariarad [96]

The underlying arithmetic progression is

-15, 0, 15, 30, ...

starting with $a_1=-15$ and with a common difference of $d=15$ between terms. Recursively, this sequence is given by

$\begin{cases}a_1=-15\\a_n=a_{n-1}+15&\text{for }n>1\end{cases}$

So we have

$a_2=a_1+15$

$a_3=a_2+15=a_1+15\cdot2$

$a_4=a_3+15=a_1+15\cdot3$

and so on, so that the explicit rule for the sequence is

$a_n=a_1+15(n-1)=15n-30$

for $n\ge1$ .

The series consists of 15 terms, since

$195=15n-30\implies15n=225\implies n=15$

So we have

$-15+0+15+\cdots+195=\displaystyle\sum_{n=1}^{15}(15n-30)=15\cdot\frac{15\cdot16}2-30\cdot15=1350$

and the answer would be B.

But, remember, you're rounding to the nearest hundreth...
