Find the arc length if the measure of the central angle is 80° and the radius
is 8 inches.

Answers

Answer 1

Answer:

[tex]\frac{32\pi }{9}[/tex] or [tex]11.17[/tex]

Step-by-step explanation:

The formula for arc length is [tex]2\pi r( \frac{x}{360} )[/tex] where "r" stands for radius and "x" stands for your angle

[tex]2\pi 8(\frac{80}{360} )[/tex]

[tex]=16\pi (\frac{80}{360} )[/tex]

[tex]=16\pi (\frac{2}{9})[/tex]

[tex]=\frac{32\pi }{9}[/tex]

Answer:

  (3, 1)

Step-by-step explanation:

We assume you want the solution to the system ...

2x−3y=3x=y+2

The second equation gives a nice expression for x, so we can use that in the first equation.

  2(y+2) -3y = 3 . . . . substitute for x in the first equation

  2y +4 -3y = 3 . . . . . eliminate parentheses

  -y = -1 . . . . . . . . . . . collect terms, subtract 4

  y = 1 . . . . . . . . . . . . multiply by -1

  x = 1 +2 = 3 . . . . . . substitute for y in the second equation

The solution is (x, y) = (3, 1).

Step-by-step explanation:

Simplificando

6x + -2 + 2x = -2 + 4x + 8

Reordenar los términos:

-2 + 6x + 2x = -2 + 4x + 8

Combinar términos semejantes: 6x + 2x = 8x

-2 + 8x = -2 + 4x + 8

Reordenar los términos:

-2 + 8x = -2 + 8 + 4x

Combinar términos semejantes: -2 + 8 = 6

-2 + 8x = 6 + 4x

Solving

-2 + 8x = 6 + 4x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-4x' to each side of the equation.

-2 + 8x + -4x = 6 + 4x + -4x

Combine like terms: 8x + -4x = 4x

-2 + 4x = 6 + 4x + -4x

Combine like terms: 4x + -4x = 0

-2 + 4x = 6 + 0

-2 + 4x = 6

Add '2' to each side of the equation.

-2 + 2 + 4x = 6 + 2

Combine like terms: -2 + 2 = 0

0 + 4x = 6 + 2

4x = 6 + 2

Combine like terms: 6 + 2 = 8

4x = 8

Divide each side by '4'.

x = 2

Simplifying

x = 2

What is the average rate of change over the interval 1≤x≤3?

Answers

Answer:

the answer is 3

Step-by-step explanation:

just guessed and got it right since it wasn't 1 or 2 because i tried searching up the answer and they were around 2 but rlly close to 3

The rate of change of y with respect to x is 3.

We have a graph of a Non - linear function.

We have to determine the average rate of change over the interval

1 ≤ x ≤ 3.

What do you understand by the Average rate of change of two quantities plotted along X and Y axis respectively?

It indicates the rate of change of y with respect to x. Mathematically -

[tex]$r=\frac{dy}{dx}[/tex]

or

[tex]$r =\frac{y(2)-y(1)}{x(2) -x(1)}[/tex]

According to the question -

The coordinate points plotted area s follows -

X    Y

1    -2

2    0

3    4

Now, the average rate of change →

[tex]$r =\frac{y(2)-y(1)}{x(2) -x(1)}[/tex]

[tex]$r =\frac{4-(-2)}{3-1}[/tex]

r = 3

Hence, the rate of change of y with respect to x is 3.

Number line graph with open circles on 0 and 24 and shading in between.
Number line graph with closed circles on 0 and 24 and shading in between.

Answers

Answer:

Number line graph with closed circle on 24 and shading to the right.

Step-by-step explanation:

First, the graph has to have a closed circle on only 24.

Since she has $61 and needs at least $85 to buy a skateboard, she needs to have at least $24 saved to buy one.

This means the last 2 answer choices are wrong, because there cannot be shading in between.

The first answer choice is also wrong because it puts a open circle, instead of a closed one, on 24.

So, the correct answer is Number line graph with closed circle on 24 and shading to the right.

If you know that a denominator in your ratio table is 12 and one of
the other ratios is 1/3, what numerator should you apply to your
12 denominator to make that ratio have the same value?

Answers

Answer:

the numerator is 4

Step-by-step explanation:

1/3 = ?/12

How did the values of the denominator change from 3 in the fraction 1/3 to 12 in the fraction ?/12? 3 was multiplied by 4 to get 12.

Then, since 12 is 4 times 3, then the missing numerator must be 4 times 1.

1/3 = 4/12

3 times the length of a field increased by 4 times the width gives 24 units. Two times the length decreased by 3 times the width is -1 unit. Find the dimensions

Answers

Answer:

width = 3

length = 4

Step-by-step explanation:

Ok so you can form a system of equations where w is the width and l is the length:

3l + 4w = 24

2l - 3w = -1

you want to eliminate one of the variables and then solve, so you can first take the top equation and multiply both sides by 2:

6l + 8w = 48

next, multiply the second equation by 3:

6l - 9w = -3

now that both include 6l, you can subtract the two equations

6l + 8w = 48

- (6l - 9w = -3)

17w = 51

divide both sides by 17

w = 3

Plug w = 3 into the equation 3l + 4w = 24:

3l + 4 * 3 = 24

3l + 12 = 24

subtract 12 from both sides

3l = 12

divide both sides by 3

l = 4
