Answer: x^4X\sqrt{x}

Step-by-step explanation: x9" was replaced by "x^9".

Rules for simplifing variables which may be raised to a power:

  (1) variables with no exponent stay inside the radical

  (2) variables raised to power 1 or (-1) stay inside the radical

  (3) variables raised to an even exponent: Half the exponent taken out, nothing remains inside the radical. examples:

     (3.1) sqrt(x8)=x4

    (3.2) sqrt(x-6)=x-3

   (4) variables raised to an odd exponent which is  >2  or  <(-2) , examples:

     (4.1) sqrt(x5)=x2•sqrt(x)

    (4.2) sqrt(x-7)=x-3•sqrt(x-1)

Applying these rules to our case we find out that

     SQRT(x9) = x4 • SQRT(x)  

Simplified Root :

x4 • sqrt(x)

Answer:

Answer is 3^4/5*a^2*b*c^2

Answer:

x = 26

Step-by-step explanation:

The sum of the angles around point O = 360°, thus

x + 3x + 256 = 360 , that is

4x + 256 = 360 ( subtract 256 from both sides )

4x = 104 ( divide both sides by 4 )

x = 26

Answer:

See below:

Step-by-step explanation:

A. y = 30 + 12.50x

Let x be the number of people. It costs 12.50 per person, so y = 12.50x. Notice how the delivery fee is not per person, meaning that the delivery fee is not impacted by the amount of people buying it. Thus, y = 12.50x + 30

B. c = 0.12m + 8.00

See explanation of A:

C. 2

The slope of a line in y-intercept form ( y = mx + b ), is the number before the x. In this case, there is a 2 before the x.

D. y = 2/3x - 3

In slope intercept form, y = mx + b. Plug in the values of m ( slope ) and b( y-intercept ) and you get y = 2/3x - 3

E. y = 1/2x

The slope can be found by dividing the change of y by the change of x. Our points are (0,0) and (2,1). The change in y is 0-1, which is -1; the change in x is (0 - 2), which is -2. -1/-2 is 1/2 so the slope of the line is 1/2. Because when x = 0, y = 0 too, there is no y-intercept, so the equation of the line is y = 1/2

Answer:

The answer is B.

Step-by-step explanation:

Y = the holiday meal costs

If they’re charging a holiday meal per person the equation would be 12.50x = y

But we also have a $30 delivery fee so it would be

12.50x + 30 = y

So the equation represents

A holiday meal costing 12.50 is ordered for an x amount of people. There is also a $30 delivery fee. The meal costed y amount of dollars.

(a) Based on the given data, there appear to be short-term fluctuations in the sales of the ice-skating rink. The sales figures vary from quarter to quarter, with some quarters showing higher sales and others showing lower sales. This suggests the presence of short-term or seasonal trends in the data. For example, there is a notable increase in sales in quarters 1, 5, and 6, followed by a decrease in quarters 3, 4, and 8. This pattern indicates a possible seasonal or cyclical trend in the sales of the ice-skating rink.

(b) To calculate the 3-period moving averages, we take the average of the sales data over a window of three consecutive quarters and compute the average for each subsequent quarter. The moving averages smooth out the fluctuations in the data and provide a clearer picture of the underlying trend.

Quarter 1: (7555 + 6695 + 5415) / 3 = 6555

Quarter 2: (6695 + 5415 + 4150) / 3 = 5420

Quarter 3: (5415 + 4150 + 7310) / 3 = 5625

Quarter 4: (4150 + 7310 + 7015) / 3 = 6158.33

Quarter 5: (7310 + 7015 + 5435) / 3 = 6586.67

Quarter 6: (7015 + 5435 + 3885) / 3 = 5445

Quarter 7: (5435 + 3885 + 0) / 3 = 3106.67

Quarter 8: (3885 + 0 + 0) / 3 = 1295

(c) The moving averages can be plotted on a graph with the x-axis representing the quarters and the y-axis representing the sales figures. Each moving average value is plotted in the corresponding quarter.

(d) Based on the calculated moving averages, we can make a prediction for the sales taken in the following two quarters. The prediction will be the average of the sales figures for the last three quarters.

Prediction for Quarter 9: (7015 + 5435 + 3885) / 3 = 5445

Prediction for Quarter 10: (5435 + 3885 + 0) / 3 = 3106.67

Therefore, the prediction for the sales taken in the following two quarters is £5,445 for Quarter 9 and £3,107 for Quarter 10.

Answer:

x = 2/3 or x = -2/3

Step-by-step explanation:

Solve for x over the real numbers:

9 x^2 = 4

Hint: | Divide both sides by a constant to simplify the equation.

Divide both sides by 9:

x^2 = 4/9

Hint: | Eliminate the exponent on the left-hand side.

Take the square root of both sides:

Answer:x = 2/3 or x = -2/3

The developer can have a maximum of 40 lots on the 16-acre subdivision.

To calculate the number of lots the developer can have on the 16-acre subdivision, we need to subtract the area occupied by streets and common areas from the total area and then divide it by the minimum lot size.

1 acre is equal to 43,560 square feet, so 16 acres is equal to 16 * 43,560 = 696,960 square feet.

The streets and common areas will take up 30% of this overall area:

30% of 696,960 = 0.3 * 696,960 = 209,088 square feet.

Now we subtract the area occupied by streets and common areas from the total area to find the area available for the lots:

696,960 - 209,088 = 487,872 square feet.

Since the minimum lot size is 12,000 square feet, we divide the available area by the minimum lot size to find the number of lots:

487,872 / 12,000 = 40.656.

Since we cannot have a fraction of a lot, the developer can have a maximum of 40 lots on this property.

As a result, the 16-acre subdivision may only accommodate a maximum of 40 lots from the developer.

Answer:

average speed   = distance / time

60 =  distance /   (13.20 - 10.40)

13.20 - 10.40  =  2 hours 40 minutes  =  2 2/3  hours

60 = distance / 8/3  = 3 d / 8     (where d = distance)

3d = 480

d = 480/3  = 160 miles

The distance between the station in Boston and the one in Stamford is 160 miles.

Distance is calculated by the formula:

= Speed x Time

The Speed is 60 mph as given.

The time is:

= 1:00 pm  - 10:20AM

= 2 hrs 40 minutes

In decimals this is:

= 2 + 40/60 minutes

= 2 + 2/3

= 2.67 hours

The distance is therefore:

= Speed x Time

= 60 x 2.67

= 160 miles

Answer:

12 girls

Step-by-step explanation:

So the ratio of girls to boys is 4:3 and if there are 9 boys you multiply the number 3 by 3 to get 9 and do the same to the other side to get 12

Distribute 4 through the parentheses.

4x + 12 = 4x + 12

Subtract 12 from both sides.

4x + 12 - 12 = 4x + 12 - 12

Subtract twice.

4x = 4x

Subtract 4x again.

4x - 4x = 4x - 4x

According to the diagram provided, Kyle is creating a frame for a model car by placing two rods together. To justify why AB equals 10, we can use the Segment Addition Postulate.

The Segment Addition Postulate states that if three points A, B, and C are collinear (meaning they lie on the same line), then point B is between points A and C if and only if the sum of the lengths of segments AB and BC is equal to the length of segment AC. In this case, the diagram shows points A, B, and C on a line, where A is the left endpoint, B is the midpoint, and C is the right endpoint. Since point B is the midpoint of segment AC, it divides the segment into two equal parts. Therefore, the length of segment AB is equal to the length of segment BC, and since the lengths are equal, we can conclude that AB is equal to 10 units. Hence, the justification for AB being 10 is based on the Segment Addition Postulate, as it guarantees that point B is the midpoint of segment AC.

Where;

a > 0 and b > 0

The location of the x-intercept is given by the values of x when y = 0 which are obtained as follows;

When y = 0, y = a·cos(b·x) = 0

The total Distance between all points is 15. This is the shortest distance between all points, so it is the time needed to travel between them

In order to calculate the time needed, we need to consider the distances between each point.

This can be done using the Pythagorean Theorem, which states that the hypotenuse of a right triangle is equal to the square root of the sum of the squares of the other two sides.

For this problem, we can treat each segment as the hypotenuse of a right triangle, where the other two sides are the distances between each point.Using this method,

we can calculate the distances between each point:b1 to b2: distance = sqrt((b2 - b1)^2) = sqrt((8 - 10)^2) = 2b2 to b3: distance = sqrt((b3 - b2)^2) = sqrt((15 - 8)^2) = 7b3 to a: distance = sqrt((a - b3)^2) = sqrt((15 - 15)^2) = 0b3 to b: distance = sqrt((b - b3)^2) = sqrt((10 - 15)^2) = 5b4 to b: distance = sqrt((b - b4)^2) = sqrt((10 - 9)^2) = 1

Now that we have the distances,

we can add them up to get the total distance:2 + 7 + 0 + 5 + 1 = 15

Therefore, the total distance between all points is 15. This is the shortest distance between all points, so it is the time needed to travel between them.

So, the answer is we should take the shortest way, not the longest way.
