Find the arc length of the partial circle..

Answer:

B. Commutative Property

Step-by-step explanation:

A. Distributive property :

for example we take 256 × 1008

256 × 1008

256 ×(1000 +8)

(256 × 1000) + (256 × 8)

256000 + 2064

Answer : 258064

Distributive is distributing a number that contains 0's to make it easier for one self

B. Associative Property of Addition :

for example (230 + 125) + (390 + 460)

if we change it like this or in any order than particularly changes the grouping

(230 + 460) + (390 + 125)

D. Associative Property of Multiplication

(230 × 125) × (390 × 460)

it's the same as the previous example just in Multiplication

The equation demonstrates the commutative property of addition, which states that the order of addition does not affect the sum. Hence option C is the answer.

The equation a + (b + 7) = (b + 7) + a is an example of the commutative property of addition. This property states that the order in which two numbers are added does not change the sum.

In other words, for any numbers a and b, the equation A+B = B+A holds true. This principle applies to ordinary numbers; for example, adding 2 + 3 will give the same result as adding 3 + 2.

Answer:

1, 9 and 12

Step-by-step explanation:

55

(f ○ g )(2) = f(g(2) ← from table g(2) = 3, thus

f(g(2)) = f(3) = 1 ← from table f(3) = 1

57

(g ○ f )(3) = g(f(3)) = g(1) = 9

58

(g ○ f )(6) = g(f(6)) = g(9) = 12

59

(f ○ f)(4) = f(f(4)) = f(3) = 1

Answer:

right

Step-by-step explanation:

You would move it towards the right because that adds a place value while moving it to the left takes away a place value.

When you multiply a number by powers of 10, the decimal point moves to the right as many places as there are zeros in the multiplier. For example, multiplying 1.2 by 10 gives 12, because the decimal point moves one place to the right.

In mathematics, when you multiply a number by 10, 100, 1,000, and so forth (powers of 10), you move the decimal point to the right as many places as there are zeros in the multiplier. This is because you are increasing the value of the number by a factor of 10 for each move to the right.

For instance, if you multiply 1.2 by 10, the result is 12. The decimal point has moved one place to the right because there is one zero in 10. If you multiply 1.2 by 1,000, the result is 1,200. The decimal point has moved three places to the right because there are three zeros in 1,000.

This understanding makes it easier to handle multiplication of numbers by powers of 10. But remember, this only applies when multiplying. When dividing, the decimal point moves to the left.

Answer:

y = (-1)*2^(x + 1)

Step-by-step explanation:

This one is not a line. It is something raised to a power. In addition, there is an ugly minus sign somewhere.

First of all, every answer is some sort of power of 2. All of them are 2^x but we don't exactly know how x words. It is not a simple y = 2^x because the first one is - 4 not - 2.

So there is an extra power somehow.

Try

y = 2^(x + 1) That looks promising

x = 1

y = 2^(1 + 1)

y = 2^2

y = 4

===============

Try another one

x = 2

y = 2^(2 + 1)

y = 2^3

y = 8

==============

I think you'll find that the other two are well behaved. and come to the answer (except for the minus) as they should.

What about that minus.

y = (-1)*2^(x + 1) should give a minus y value for any term.

Step-by-step explanation:

A and A' does not mirror the image with reference to the given Line.

A pair of numbers called coordinates are used to locate a point or a form in a two-dimensional plane. The x-coordinate and the y-coordinate are two numbers that define a point's location on a 2D plane.

Given Two cartesian planes and we need to calculate if Points A and A' are mirror images with respect to the given reference line,

For graph 1,

Since the Given line is horizontal the normal distance between Point A and point A' is observable,

In our case,

Distance from point A to the line = Distance from A' to the line = 1 unit.

For graph 2,

Since the Given line is horizontal the normal distance between Point A and point A' is observable,

In our case,

Distance from point A to the line = 6 units

Distance from A' to the line = 3 units

Thus, A and A' does not mirror the image with reference to the given Line.

Step-by-step explanation:There is 6 pounds plus the the other pound then your left with 22-16=6 7 pounds times 16 112+6=118

Answer:

The total weight of the bowling ball in ounces is 173 ounces

Step-by-step explanation:

To find this, first change the pounds to ounces by multiplying by 16.

10lbs * 16 = 160 ounces

Now add the ounces to that.

160 + 13 = 173 ounces

The total weight of Nene's bowling ball is 10.8125 pounds, after converting 13 ounces to pounds (since there are 16 ounces in 1 pound) and adding it to the 10 pounds.

To find the total weight of Nene's new bowling ball, we must first recognize that the weight is given in two different units: pounds and ounces. There are 16 ounces in 1 pound.

Step 1: Identify the weight in pounds and ounces.

Weight in pounds: 10 pounds

Weight in ounces: 13 ounces

Step 2: Convert the ounces to pounds. Since there are 16 ounces in 1 pound, we divide 13 ounces by 16 to get the weight in pounds.

13 ounces / 16 = 0.8125 pounds

Step 3: Add the weights to get the total weight in pounds.

10 pounds + 0.8125 pounds = 10.8125 pounds

Therefore, the total weight of the bowling ball is 10.8125 pounds.

The domain of the function is the interval -------> [0,∞)

All real numbers greater than or equal to zero

The range of the function is the interval -----> [0,∞)

All real numbers greater than or equal to zero

see the attached figure to better understand the problem  

Answer:

The range of the graph is all real numbers greater than or equal to 0.

Step-by-step explanation:

Consider the provided function [tex]f(x)=\sqrt{x}[/tex].

Domain of the function is the set of all possible x values which a function can take.

Range of the function is the set of all output values or the values produced by the function.

Now, consider the provided function.

The value of x can not be a negative number because the square root of negative number is not a real number.

Thus, the domain of the function must be zero or greater than zero.

The graph of the function is shown in figure 1.

From the graph it can be observed that the values produced by that function is all real numbers greater than or equal to 0.

Therefore, the required answer is: The range of the graph is all real numbers greater than or equal to 0.

a=11,b=7

Step-by-step explanation:

To get to the result we firs multiply the figures on the left hand side.

multiplication of each term with its similar term is shown:

5×-4=-20

x⁷ₓx⁴=x¹¹. Here we add the powers because we are multiplying indices to the same base.

y²ₓ y⁵= y⁷

Thus the correct answer is a=11 and b=7

Answer:

[tex]a=11,b=7[/tex]

Step-by-step explanation:

The given equation is

[tex](5x^7y^2)(-4x^4y^5)=-20x^ay^b[/tex]

Recall that [tex]a^m\times a^n =a^{m+n}[/tex]

We simplify the left hand side to obtain;

[tex]-20x^{7+4}y^{2+5}=-20x^ay^b[/tex]

This implies that;

[tex]-20x^{11}y^{7}=-20x^ay^b[/tex]

Comparing exponents, we have

a=11,b=7

The first choice is correct.

The measure of side length x to the nearest tenth is approximately 2879.4 meters.

The figure in the image is a right triangle.

From the figure;

Angle θ is the complement of the given angle.

Ange θ = 90 - 10 = 80 degrees

Adjacent to angle θ = 500 m

Hypotenuse = x

To solve for the hypotenuse of the right triangle, we use the trigonometric ratio:

Note that;

cosine = adjacent / hypotenuse

Hence;

cos( θ ) = adjacent / hypotenuse

Plug in the values:

cos( 80 ) = 500 / x

Solve for x:

x × cos( 80 ) = 500

x = 500 / cos( 80 )

x = 2879.4 m

Therefore, the value of x is 2879.4 meters.

Answer:

(-1 + √2) and (-1 - √2)  

Step-by-step explanation:

Given in the question the equation

y = x² + 2x - 1

To find the x-intercept, substitute in 0 for y

0 = x² + 2x - 1

To find value of x use quadratic equation

x = -b ± √b²-4ac / 2a

  here a = 1

           b = 2

           c = -1

x1 = -2 + √2²-4(1)(-1) / 2(1)

   = -2 + 2√2 / 2

   = -1 + √2  

x2 = -2 - √2²-4(1)(-1) / 2(-1)

   = -2 - 2√2 / -2

   = -1 - √2  

There are many methods of doing this. This one finds the median; however, instead of halving, you can use quarters instead.

First order the data, ascendingly:

10, 17, 18, 18, 18, 20, 20, 25, 25, 30, 30

Find the median:

For an even number of values: The number of values / 2

For an odd number of values: The number of values + 1 / 2

11 is odd.

11 + 1 / 2

12 / 2 = 6

The median is at the 6th position.

10, 17, 18, 18, 18, 20, 20, 25, 25, 30, 30

The median is 20.

Other method:

You don't need this step.

Using the values lower than the median, exclusive, find the median of the lower values;

For an odd number of values: The number of values + 1 / 2

10, 17, 18, 18, 18

5 + 1 / 2 = 6 / 2 = 3

The median of the lower values is at position 3.

This is the lower quartile.

10, 17, 18, 18, 18

Other method:

For an odd number of values: The number of values + 1 / 4

11 + 1 / 4 = 12 / 4 = 3

10, 17, 18, 18, 18, 20, 20, 25, 25, 30, 30

Using the values greater than the median, exclusive, find the median:

For an odd number of values: The number of values + 1 / 2

20, 25, 25, 30, 30

5 + 1 / 2 = 6 / 2 = 3

The median of the upper values is at position 3.

20, 25, 25, 30, 30

This is 25.

This is the upper quartile.

Other method:

For an odd number of values: (The number of values + 1 / 4) * 3

(11 + 1 / 4) * 3 = (12 / 4)  * 3 = 3 * 3 = 9

10, 17, 18, 18, 18, 20, 20, 25, 25, 30, 30

Your interquartile range is 3 - 25

25 - 3 = 21
