[ please help! ] The graph below shows a line segment PQ.

Tpy6a [65]

Answer:

Slope of the line segment PQ is 1/2.

Step-by-step explanation:

We are given with a line connecting two points P and Q.

The coordinates of P are (4,4) and the coordinates of Q are (-2,1).

Slope of line joining two points $(x_{1},y_{1})$ and $(x_{2},y_{2})$

is given by the formula $\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

Hence the slope of the line PQ is $\frac{1-4}{-2-4}=\frac{-3}{-6}= \frac{1}{2}$

Therefore correct option is 'C' that is 1/2.

Which equation represents the formula for the general term, gn, of the geometric sequence 3, 1, 1/3, 1/9, . . .?

dedylja [7]

Answer:

Explicit form: $g_n=3(\frac{1}{3})^{n-1}$

Recursive form: $g_n=\frac{1}{3}g_{n-1}$ with $g_1=3$ .

Step-by-step explanation:

The first term is 3 and we are dividing by 3 each time.

Another way to say we are dividing by 3 each time is to say we are multiplying by factors of 1/3.

If the first term is $a$ and $r$ is the common ratio then the geometric sequence in explicit form is:

$a_n=a(r)^{n-1}$

$g_n=3(\frac{1}{3})^{n-1}$

The recursive form for a geometric sequence is $a_n=ra_{n-1}$ with $a_1=a$ where $r$ is the common ratio and $a$ is the first term.

So the recursive form for our sequence is $g_n=\frac{1}{3}g_{n-1}$ with $g_1=3$ .

The rectangle below has an area of 35x^3 square meters and a width of 5x meters.

Artemon [7]

$a = lw$

$35 {x}^{3} = l(5x)$

$\frac{35 {x}^{3} }{5x} = l$

$7 {x }^{2} = l$

The length is 7x²
