On The Unit Circle, An Arc Of Length 2 Subtends An Angle, . What Is The Radian Measure Of ?

Answers

Answer 1

Answer:

[tex](d)\ \beta = 2\ rad[/tex]

Step-by-step explanation:

Given

[tex]L =2[/tex] -- length of the arc

[tex]r = 1[/tex] --- radius of a unit circle

[tex]\beta =[/tex] the subtended angle

Required

Find [tex]\beta[/tex]

The length of an arc is:

[tex]L = r * \beta[/tex]

This gives:

[tex]2 = 1 * \beta[/tex]

[tex]2 = \beta[/tex]

Make [tex]\bets[/tex][tex]\beta[/tex] the subject

[tex]\beta = 2[/tex]

Hence:

[tex]\beta = 2\ rad[/tex]

Answers

Answer:

Step-by-step explanation:

this is about the volume of each size of candle.  so the area of the circle , times the height of the candle is the amount of wax needed or it's volume.  

area of a circle is  = [tex]\pi[/tex][tex]r^{2}[/tex]

then the big candle is [tex]\pi[/tex][tex]2^{2}[/tex] = 12.56637

times 10 for it's height = 125.6637

so that's the big candles volume

then make 20 of those = 2513.27

a small candle is [tex]\pi[/tex][tex]1.5^{2}[/tex] = 7.068583471

and it's 6 cm tall so times 6 = 42.41150082

Now divide the small candle volume into the 20 big ones to see how many small ones can be made

2513.27 /  42.41150082 = 59.259

so just a bit over 59 small candles can be made from 20 big candles

Answer:

  work shown is incorrect

Step-by-step explanation:

An equal sign is a sacred symbol. It needs to be treated with respect. The equal sign can only be used legitimately when the expression on one side is actually equal to the expression on the other side.

Here, you seem to have ...

  16 -7 = 11 . . . . . FALSE

  9 ≠ 11 . . . . . . . . why the equal sign should not be used

So, the inequality you're trying to solve depends on which of the "equal" values you intend.

7 + x < 16 - 7

Subtracting 7 from both sides gives ...

  x < 2

This graphs as an open circle at x=2 and shading of the number line to the left from there. See the attachment for the graph.

__

7 + x < 11

Subtracting 7 from both sides gives ...

  x < 4

This graphs as an open circle at x=4 and shading of the number line to the left from there. The graph is similar to the one attached, but has the point at x=4 instead of x=2.

__

Your solution

Somehow you have concluded that x < 11. If that is correct, and you want to graph that, you need to draw an open circle at x=11 (not x=12), and shade the number line to the left from that point. A solid dot at x=12 and a line left of that does not represent the inequality x < 11.

A solid dot is used only for the "or equal to" case. You have graphed x ≤ 12.

Find the circumference and area of a circle A with a diameter of 26 inches.
Please I need the answer ASAP. Thank you very much.

Answers

Answer:

Circumference: 81.681 in; Area: 530.929 in

Step-by-step explanation:

To find circumference we use the formula pi x diameter. Which in this case is pi x 26 in, or approximately 81.681 in.

For the area, we use pi x r^2. r = 1/2 d, so r = 13in. Therefore, the area is equal to 169 x pi in, which is about 530.929 in.
