Answer:

622

Step-by-step explanation:

The n-th term of an arithmetic sequence is given by the formula ...

an = a1 +d(n -1)

where a1 is the first term (6), and d is the common difference (14-6=8).

Then the 78th term is ...

a78 = 6 + 8(78 -1) = 6 + 616 = 622

The 78th term is 622.

What is the circumference of circle P? Express your answer in terms of π.

Zolol [24]

Answer:

Circumference of a circle= $2\pi r$

Step-by-step explanation:

The circumference of any circle is the total length of its boundary which can be calculated by the formula:

Circumference of a circle= $2\pi r$

Where 'r' is the radius of the circle

For, the given circle the circumference can be find in terms of $\pi$ by putting some value of radius in the formula, which gives the circumference in terms of $\pi$ .

Set up a ratio of object height to shadow length.
So x/32=6/8
8(4)=32 so 6(4) would be 24.

If r(x) = 2 – x2 and w(x) = x – 2, what is the range of (w circle r) (x)?

VashaNatasha [74]

Answer:

$(-\infty, 0)$

Step-by-step explanation:

(w circle r) (x) is the composite function(w of r(x)), that is, w(r(x))[/tex]

We have that:

$r(x) = 2 - x^{2}$

$w(x) = x - 2$

Composite function:

$w(r(x)) = w(2 - x^{2}} = 2 - x^{2} - 2 = -x^{2}$

$-x^{2}$ is a negative parabola with vertex at the original.

So the range(the values that y assumes), is:

$(-\infty, 0)$
