What is the difference between the Commutative Property and Associative Property of addition?

Answer:

First choice

y = 3ˣ

Step-by-step explanation:

It is easier if you examine the obviously wrong choices

Choice 2, y = 9x is incorrect because at x = 0, y = 9x should be 0, instead it is 1

Choice 3 , y = 3x is incorrect for the same reason

Choice 4 y = x³ is incorrect because at x = 0, x³ should be 0, instead it is 1

Correct choice is the first one: y = 3ˣ

Let's check:

x = 0,  y = 3⁰  = 1 because any number raised to the power 0 is 1

x = 1, y = 3¹ = 3; because any number raised to the power 1 is 1itself

x = 2; y = 3² = 9 ; so fts

Answer:

The equation that can be used to find y, the height of the first bounce, in inches, when the ball is dropped from a height of x inches is y=x/2. This can be determined by analyzing the data in the table:

-When the ball is dropped from a height of 10 inches, the height of the first bounce is 5 inches (y=5).

-When the ball is dropped from a height of 20 inches, the height of the first bounce is 10 inches (y=10).

-When the ball is dropped from a height of 30 inches, the height of the first bounce is 15 inches (y=15).

In all these cases, the height of the first bounce is half the height of the drop, meaning that the equation y=x/2 is the correct one

Answer:

B) y = x/2

Step-by-step explanation:

When the ball is dropped 10 inches, the ball bounces 5 inches

5 = 10/2

When the ball is dropped 20 inches, the ball bounces 10 inches.

10 = 20/2

When the ball is dropped 30 inches, the ball bounces 15 inches.

15 = 30/2

Value of R = 1.72×10¹¹ meter

The correct option is B.

Expressions in math are mathematical statements that have a minimum of two terms containing numbers or variables, or both, connected by an operator in between. The mathematical operators can be of addition, subtraction, multiplication, or division.

For example, x + y is an expression, where x and y are terms having an addition operator in between.

Given, expression

R = √[1/{1/(149×10⁹)² - 1/(298×10⁹)²}]

R = √[1/{1/(149×10⁹)² - 1/(298×10⁹)²}]

R = √[1/{(6.71×10⁻¹²)² - (3.36×10⁻¹²)²}]

R = √[1/{4.50×10⁻²³ - 1.13 × 10⁻²³}]

R = √[1/3.37×10⁻²³]

R = √2.97×10²²

R = 1.72×10¹¹ meter

Hence, 1.72×10¹¹ meter is value of R.

The radius of the cylinder is r=50.129

The radius of the cylinder is the radius of a base. The altitude of the cylinder is a perpendicular segment from the plane of one base to the plane of the other and the height of the cylinder is the length of the altitude. The axis of a cylinder is the segment containing the centers of the two bases

The volume of a cylinder is 600,000.

The height is 76cm and the radius is unknown. How do you solve it?

The volume of a right cylinder can be determined by πr²h,

Answer:

  7:48 p.m.

Step-by-step explanation:

You want to know when lights with periods 36 s, 64 s, and 110 s will change simultaneously again if they do so at 11 a.m..

The lights will change simultaneously after a time that is the least common multiple (LCM) of the periods of the lights.

The least common multiple is the product of the unique factors in each of the numbers:

  36 = 2² · 3²

  64 = 2⁶

  110 = 2 · 5 · 11

The unique factors are 2⁶, 3², 5, and 11. Their product is 31680. The lights will change simultaneously again after 31680 seconds.

We can convert this to hours, minutes, and seconds by repeated division by 60:

  31680 / 60 = 528 r 0

  528 / 60 = 8 r 48

31680 seconds is 8 hours, 48 minutes, and no seconds.

Adding that time to 11 a.m. gives a clock time of ...

  11:00 +8:48 = 19:48 = 7:48 p.m.

The lights will change simultaneously again at 7:48 p.m..

Step-by-step explanation:

To calculate the percentage of the down payment to the purchase price, you can use the following formula:

(down payment / purchase price) x 100

So in this case:

(20000 / 200000) x 100 = 0.1 x 100 = 10

Therefore, the down payment of 20000 is 10% of the purchase price of 200000.

Therefore , the solution of the given problem of circle comes out to be

angle is 5π /6 .

A circle is created when every point as in plane that is specific distance apart from another point does so (center). As a result, it is a curve made up of points that are spaced apart from one another in the plane. It is rotationally symmetrical about the center at all angles. Every pair of endpoints in the plane that make up a circle are evenly spaced away from the "center" and form a closed, two-dimensional object. A specular symmetries line is produced by a line that passes through the circle. It is rotationally symmetrical about the center at all angles.

Answer: 69

Step-by-step explanation:

In the equation 692 = 4,761, we can see that 692 is being multiplied by some number to get 4,761. To find that number, we can divide 4,761 by 692:

4,761 / 692 = 69.

So, 4,761 / 69 = 69

In this case, 692 is being multiplied by 69 to get 4,761, so 69 is the value we get when we divide 4,761 by 69.

An equation is represented by the table is y= -4x+3. Therefore, option B is the correct answer.

The general equation of a straight line is y=mx+c, where m is the gradient, and y = c is the value where the line cuts the y-axis. This number c is called the intercept on the y-axis.

From the given table, we have coordinates (0, 3) and (1, -1)

The cafe served 49 regular coffees.

You can use the proportion of regular coffees to the total number of coffees to find out how many regular coffees were served.

If 70% of the coffees served were regular, that means that 100-70 = 30% of the coffees served were decaffeinated.

To find out how many regular coffees were served, you can use the following proportion:

(Number of regular coffees) / (Total number of coffees) = 70% / 100%

You can then cross-multiply and solve for the number of regular coffees:

Number of regular coffees = (70/100) * (Total number of coffees)

Given the Total number of coffees = 70, you can substitute that and get:

Number of regular coffees = (70/100) * 70 = 49

The periodic fixed costs of the company, based on the cost function, are $1,000.

The fixed costs refer to the period costs that do not change in total concerning the production or activity level and they relate to a financial period.

The fixed cost per unit decreases as more units are produced and vice versa.  However, within the relevant range, the fixed cost for the period remains the same.

A cost function is a model or formula that shows the total costs based on different cost behaviors (fixed and variable) and the relationship of costs to the production quantity.

Cost functions can be used to predict the total costs to be incurred under different production levels.

In this situation, the cost function, C = 1000 + 3.75q, shows that the fixed cost per period is $1,000 and $3.75 per unit (variable).

Answer:

Step-by-step explanation:

First, we will use the property of radicals that states that (a √b) * (c √d) = (ac) √(bd). Since the expression has both multiplication and addition, we will break the expression down into its components and simplify each component separately.

6√x+7√(54) = 6√x + 7√(27*2) = 6√x + 7√27 * 7√2 = 6√x + 7√27 * (2*√2) = 6√x + 14√27 * √2 .

Next, we will simplify the second component of the expression: 12√(6) = 12√(2*3) = 12√2 * 6√3 = (4*3)√2 * 6√3 = 12√2 * 6√3.

Finally, we can combine the two separate parts of the expression to get the simplified version: 6√x + 14√27 * √2 - 12√2 * 6√3 = 6√x + 14√27 * √2 - 12√6.

The simplified version of the expression is 6√x + 14√27 * √2 - 12√6, in exact terms (no decimals).
