Circumference is simply:
2*r*π or d*π

r = radius
d= diameter
C = circumference (perimeter of circle)

If d = 5m then C is d*π = 5π meters

If r = 2m then C is 2*r*π = 2*2*π = 4π meters

If d = 3m then C is d*π = 3π meters

If r = 3m then C is 2•r•π = 2*3*π = 6π meters

If d =2m then C is d*π = 2π meters

Okay so if the line goes through half of the circle it's called the radius. If it goes through the whole thing it's the diameter. The equation to find the circumference is pi times diameter. So the first one is 5pi, second is 4pi, third is 3pi, fourth is 6pi, and the last one is 2pi.

Can some help me with this problem
Svetlanka [38]

Answer:


Step-by-step explanation:

So let's find the equation of the line for f(x). We know the y-intercept, also known as b in the equation of the line for f(x), is 3. (b = y-intercept = 3)

y = mx + <u>b</u>

y = mx + <u>3</u>

Now, to find the slope you must use the formula of...

(y₂ - y₁) / (x₂ - x₁)

We have two points of the line already shown. We will now use the formula to find out the slope.

(3 - 1) / (0 - 1) = 2 / -1 = -2, the slope is -2. (m = slope = -2)

y = <u>m</u>x + 3

y = <u>-2</u>x + 3

Now check the following statements and see which ones are true.

A is <em>not </em>a true statement.

B is <em>not </em>a true statement because a slope of -6 is steeper than -2. The negative slope only changes the direction of the line.

C is <em>not </em>a true statement because the slope of f(x) is not undefined.

D <u>is</u> a true statement because the line of f(x) is less steep than the slope of g(x).

KEEP IN MIND THE SLOPE IS M IN THE EQUATION OF A LINE.

Can I get some help we just started this today
Alja [10]

Answer:

-2

Step-by-step explanation:

The slope of a line tells us how y responds to a change in x.  If the slope is 2, it means that for every time x increases by 1, will will go up by 2.

We can calculate slope from a line, or with two given points.  I used points (0,4) and (3,-2).  Slope is the "Rise/Run."

The Rise:  (-2 - 4) = -6

The Run:  (3 - 0) = 3

Slope = Rise/Run = (-6/3) = -2

Norgestrel and ethinyl estradiol tablets are available containing 0.5 mg of norgestrel and 50 μg of ethinyl estradiol. How many
Bogdan [553]

Answer:

5g of norgestel are used in making 10,000 tablets.

0.5g of ethinyl estradiol are used in making 10,000 tablets.

Step-by-step explanation:

This problem can be solved as a rule of three problem.

In a rule of three problem, the first step is identifying the measures and how they are related, if their relationship is direct of inverse.

When the relationship between the measures is direct, as the value of one measure increases, the value of the other measure is going to increase too.

When the relationship between the measures is inverse, as the value of one measure increases, the value of the other measure will decrease.

Unit conversion problems, like this one, is an example of a direct relationship between measures.

First step: Grams of norgestrel

Each tablet contais 0.5mg of norgestrel. How many miligrams are in 10,000 tablets?

1 tablet - 0.5 mg

10,000 tablets - x mg

x = 10,000*0.5

x = 5,000 mg

Now we have to convert 5,000 mg to g. Each g has 1,000 mg. So:

1g - 1,000 mg

xg - 5,000 mg

1,000x = 5,000

x = \frac{5,000}{1,000}

x = 5g,

5g of norgestel are used in making 10,000 tablets.

Final step: Grams of ethinyl estradiol

50ug = 0.05 mg.

So

1 tablet - 0.05mg

10,000 tablets - xg

x = 10,000*0.05

x = 500 g

Now we have to convert 500 mg to g. Each g has 1,000 mg. So:

1g - 1,000 mg

xg - 500 mg

1,000x = 500

x = \frac{500}{1,000}

x = 0.5g,

0.5g of ethinyl estradiol are used in making 10,000 tablets.
