Answer:

7 f(t)

Step-by-step explanation:

So, our f(t) is the number of liters burned in t days. If t is 1, f(t)=f(1) and so on for every t.

w(r) id the number of liters in r weeks. This is, in one week there are w(1) liters burned.

As in one week there are 7 days, we can replace the r, that is a week, by something that represents 7 days. As 1 day is represented by t, one week can be 7t (in other words r = 7t). So, we have that the liters burned in one week are:

w(r) = w[7f(t)]

So, we represented the liters in one week by it measure of days.

So, we can post that the number of liters burned in 7 days is the same as the number of liters burned 1 day multiplied by 7 times. So:

w (r) = w[7 f(t)] = 7 f(t)

Here we hace the w function represented in terms of t instead of r.

<u>Given</u>:

The line segments are AB, DB, AB, OB and BC

We need to determine the given line segments are radius, chord, diameter, secant or tangent of circle O.

<u>Line segment AB:</u>

A secant is a line segment that intersects the circle at two points.

Thus, the line segment AB is a secant.

<u>Line segment DB (</u>\overline{D B}<u>):</u>

The diameter of the circle is line that passes through the center and touches the two ends of the circle.

Thus, from the figure, the line segment DB passes through the center and touches the two ends of the circle.

Hence, the line segment DB is the diameter.

<u>Line segment AB (</u>\overline{A B}<u>):</u>

The line joining any two points on the circle is called the chord of the circle.

Thus, from the figure, the line segment AB touches the two points on the circle.

Hence, the line segment \overline{A B} is the chord of the circle.

<u>Line segment OB (</u>\overline{O B}<u>):</u>

The radius of the circle is any line from the center of the circle to any point on the circle.

Thus, from the figure, the line segment OB is a line from center of the circle to the point B on the circle.

Hence, the line segment \overline{OB} is the radius of the circle.

<u>Line segment BC:</u>

A tangent is a point that touches the exterior point of the circle exactly one time.

Thus, from the figure, the line segment BC is a touches the circle exactly once.

Hence, the line segment BC is the tangent of the circle.

What is the equation,in point slope form,for a line that goes through (8,-4) and has a slope of -5/6
AVprozaik [17]

The point-slope formula:

y-y_1=m(x-x_1)

We have

(8,\ -4)\to x_1=8,\ y_1=-4\\\\m=-\dfrac{5}{6}[/tx]Substitute:[tex]y-(-4)=-\dfrac{5}{6}(x-8)\\\\y+4=-\dfrac{5}{6}(x-8)
