Parts of a Circle

Mathematics
1 answer:
Leto [7]3 years ago
4 0

Answer:

radius

Step-by-step explanation:

From the attachment D is a point on the circumference of the circle and B is the center of the circle.

The question demands the name of line segment DB in circle B.

Any line from the center of a circle to the circumference is called a radius.

Therefore line segment DB is a radius.

The second choice is correct.

Which equations and/or functions represent the graphed line? Select four options. f(x) = 0.2x - 4
Vanyuwa [196]

Answer:

f(x) = 0.2x - 4  (incorrect)

f(x) = 0.5x + 2  (correct)

f(x) = 1/2x + 2      (correct)

y – 3 = 1/2(x – 2)     (correct)

y – 1 = 0.5(x + 2)

Step-by-step explanation:

<em>Step 1 : Find two coordinates</em>

(0, 2) (-4, 0)

<em>Step 2 : Find the slope</em>

Slope = m = Y2-Y1/X2-X1

m = 0-2/-4-0

m = -2/-4

m = 1/2 or 0.5

<em>Step 3 : Find the y-intercept</em>

Y-intercept is where the line intersects the y-axis

c = 2

<em>Step 4 : Form the equation y=mx + c</em>

<em>Given Equations and their slope intercept forms:</em>

1) f(x) = 0.2x - 4

This is incorrect because slope is 1/2 or 0.5 and y intercept is 2

2) f(x) = 1/2x + 2

y = 1/2x + 2

This is correct because slope is 1/2 or 0.5 and y intercept is 2

3) f(x) = 0.5x + 2

y= 0.5x + 2 (As m=0.5)

This is correct because slope is 1/2 or 0.5 and y intercept is 2

4) y – 3 = 1/2(x – 2)

Rearranging in slope intercept form:

y-3=1/2x - 1

y = 1/2x-1+3

y = 1/2x + 2

This is correct because slope is 1/2 or 0.5 and y intercept is 2

5) y – 1 = 0.5(x + 2)

y -1 = 0.5x+1

y = 0.5x +1+1

y = 0.5x + 2

This is correct because slope is 1/2 or 0.5 and y intercept is 2

The graph is attached, showing the intersection point at 13.5 years and populations of 235.2 for each population.

We only consider the portion of the graph from x=0 on, since negative time is illogical.  Tracing the graph we get the intersection point.

Suppose there's 0.01895 ml of propellant in one milliliter of spray paint. What's the amount of propellant rounded to the neares
ololo11 [35]

Answer:

The amount of propellant  is 52.770 ml of spray paint

Step-by-step explanation:

We are given

0.01895 ml of propellant in one milliliter of spray paint

so,

0.01895 ml of propellant = 1 milliliter of spray paint

We can divide both sides by 0.01895

\frac{0.01895}{0.01895} ml of propellant = \frac{1}{0.01895} ml of spray paint

1 ml of propellant = \frac{1}{0.01895} ml of spray paint

now, we can divide right side

and we get

1 ml of propellant = 52.770 ml of spray paint

The amount of propellant  is 52.770 ml of spray paint
