Answer: The answer is 570.

Step-by-step explanation:

So, if you know what numbers are, when you round, this question is easy. If you take a number line and put 570 on the left side and 580 on the right side, and 575 in the middle, you almost got it. Since the number we want to round is 573, we put it in the middle of 570 and 575. And since the number is closer to 570 than 580, the answer is 570. Your welcome!

Answer:

5/7

Step-by-step explanation:

ratio of boys to girls---> 2:5

ratio sum: 2+5=7

girls ratio =5/7

OR

total of people in 7th grade choir=28

hence, no of girls in 7th grade choir=5/7 × 28

=20

proportion of girls in choir= 20/28 = 5/7

Therefore, we solve the equation.\((x^2-1)(x-2) = 0\)    to find the x-intercepts:

\(x^2-1 = 0 , x-2=0\)  

x = ±1, x = 2

An equation is a mathematical statement that shows the equality of two expressions using an equal sign (=). It is a way to describe a relationship or a condition between two or more variables.

For example, the equation "\(2x + 3 = 7\)" is an equation with the variable "x". It states that if we substitute "x" with the value "2", then the left-hand side of the equation will equal the right-hand side of the equation. In this case, 2 times 2 plus 3 is equal to 7.

To graph the function. \(f(x) = ((x^2-1)(x-2))/(x-3)\), we can start by identifying any vertical or horizontal asymptotes, x-intercepts, y-intercepts, and the behavior of the function as x approaches positive and negative infinity.

Vertical Asymptotes:

A vertical asymptote occurs when the denominator of the function equals zero. In this case, the denominator is (x-3), which equals zero when x = 3. Therefore, we have a vertical asymptote at x = 3.

Horizontal Asymptotes:

To determine the horizontal asymptote, we need to look at the behavior of the function as x approaches positive or negative infinity. One way to do this is to use long division to simplify the function:

\((x^2-1)(x-2) / (x-3)\)

\(= x^2 - x - 2 + (5x - 7)/(x - 3)\)

As x approaches infinity or negative infinity, the term \((5x - 7)/(x - 3)\) becomes very small compared to \(x^2\), so we can ignore it. Therefore, the function approaches \(y = x^2\)as x approaches positive or negative infinity. This means that. \(y = x^2\)is the horizontal asymptote.

X-Intercepts:

To find the x-intercepts, we set f(x) equal to zero and solve for x:

\(((x^2-1)(x-2))/(x-3) = 0\)

This equation is equal to zero only if the numerator equals zero, since division by zero is undefined. Therefore, we solve the equation. \((x^2-1)(x-2) = 0\) to find the x-intercepts:

\(x^2-1 = 0 , x-2=0\)

x = ±1, x = 2

Average number of road accident (n) = 11

Probability of observing exactly 7 accident o. The stretch of road next year

Poisson random variable (k) = 7

Using the poisson distribution formula :

P(x = k) = (n^k * e^-n) / k!

P(x = 7) = (11^7 × e^-11) / 7!

P(x = 7) = (19487171 × 0.0000167017) / 5040

Answer:

The price of the shirt is $24.63.

Step-by-step explanation:

Let's assume the price of the shirt is x. Then the price of the wallet will be x - 15. We know that the total cost before tax is 34.26, so we can set up the equation:

x + (x - 15) = 34.26

Simplifying, we get:

2x - 15 = 34.26

Adding 15 on both sides:

2x = 49.26

Dividing by 2:

x = 24.63

Therefore, the price of the shirt is $24.63.

The graph of g(x) = 4x, is the translation of f(x) by subtracting 3.5 units, 2 of 3.

A graph can be defined as a pictorial representation or a diagram that represents data or values.

The cost can be modeled by the function f(x)=4x+3.5, where x represents the number of games bowled.

As per the given question, the required solution would be as:

g(x) = 4x , is the translation of f(x) by subtracting 3.5 units, 2 of 3.

The graph of g(x) would be identical to the graph of f(x), but shifted 3.5 units downward, 3 of 3.

This is because the flat fee for the rental of bowling shoes is not present in the function g(x), so the y-intercept of the graph would be at (0,-3.5) instead of (0,0) in f(x) function.

The slope and the shape of the function will remain the same.

thats what i think.

Answer:

The amount of 12% note is $90,000

The amount of 9% note is $80,000

Step-by-step explanation:

Missing word "The amount of the 12% note is $ and the amount of the 9% note is $"

Selling price = $170,000

Let x be the amount of money paid short term, therefore the amount of money paid long term is (170000 - x)

Given total annual interest = $18,000

Total annual interest = Interest due to short term (x) + interest due to long term (170000 - x)

18,000 = 0.12x + 0.09*(170000 - x)

18,000 = 0.12x + 15,300 - 0.09x

18,000 = 0.03x + 15,300

0.03x = 18,000 - 15,300

0.03x = 2,700

x = 2,700/0.03

x = 90,000

So, the amount of 12% note is $90,000

So long term paid money = $170,000 - $90,000 = $80,000

So, the amount of 9% note is $80,000

Step-by-step explanation:

The total sum of the first 15 terms of the given arithmetic progression for a given problem is 1200.

initially, we have to discover the common difference

let the common difference for this question be d,

the primary term can be considered as a.

From the given information,

the whole of the 7th and 11th terms of an Arithmetic Progression is 35

At that point, the 7th term may be a + 6d, and the 11th term could be a + 10d.

and the summation of both terms is 35,

which gives the condition (a + 6d) + (a + 10d) = 35

reducing the condition, we get condition (i)

2a + 16d = 35 .......(i)

Essentially, the 9th term could ( a + 8d), and the 13th term is (a + 12d). and as per the given information, the entirety of the 9th and 13th terms is 65:    

which infers

(a + 8d) + (a + 12d) = 65

Streamlining this condition, we get:

2a + 20d = 65 ....(ii)

Presently, subtracting Condition (i) from Condition (ii), we get:

2a + 16d - 2a - 20d = 35 -65

-4d = -30

d = 7.5

Substituting this esteem of d into Condition (i) and Condition (ii), ready to fathom for a:

2a + 16(7.5) = 35

2a + 120 = 35

2a = -85

a = -42.5

In this manner, the common difference within the arithmetic progression is 7.5 and the first term is -42.5.

To discover the sum of the primary 15 terms of the arithmetic progression, we can use the equation:

S = (n/2)(2a + (n-1)d)

where S is the sum of the first n terms

a is the first term = -42.5.

d may be a common difference = 7.5

and n is the number of terms= 15

Substituting the values we have found, we get    S = (15/2)(2(-42.5) + (15-1)(7.5))

S = 15(-25 + 14(7.5))

S = 15(80)

S = 1200

Subsequently, the sum of the first 15 terms of the arithmetic progression is 1200.

Step-by-step explanation:

a. Distance = speed * time

d = st  

So substituting in the given values:

d = 20t  where t is the time it takes to travel from the hive to the flowerbed.

The total time that the bee is inflight = 13-11 = 2 minutes

= 120 seconds.

So for the return flight the time taken is (120-t) seconds.

So d = 16(120 - t).

and  we can find the distance  from the hive to flowerbed by solving the the 2 equations highlighted.

b,    d = 20t

      d = 16(120 - t).

As both right side expressions are equal to d we can write:

20t = 16(120 - t)

20t = 1920 - 16t

20t+ 16t  = 1920

t = 1920/36

  =  53.33  seconds.

So the distance from hive to flowerbed

=  53.33 * 20

Using quadratic formula,

\(x = \frac{-b\pm\sqrt{b^2 -4ac} }{2a}\)

a = 1, b = 1 and c = -930

\(x = \frac{-1\pm\sqrt{1^2 -4(1)(-930)} }{2(1)}\\\\= \frac{-1\pm\sqrt{1 +3720} }{2}\\\\= \frac{-1\pm\sqrt{3721} }{2}\\\\= \frac{-1\pm61 }{2}\\\)

The angle between the ground and the steepest slope on the real rollercoaster is approximately 89.998°.

A model rollercoaster is built to a scale of 1:32. In the model rollercoaster, the angle between the ground and the steepest slope is 110°.What is the angle between the ground and the steepest slope on the real rollercoaster?

To determine the angle between the ground and the steepest slope on the real rollercoaster, you need to consider the scale of the model rollercoaster.To find the real rollercoaster angle, you should use a scale factor that relates the model rollercoaster to the real one.

The scale factor should multiply the model angle to obtain the real one. Since the scale factor relates the model length to the real length, it should relate the horizontal distance and the vertical height.

The horizontal and vertical lengths are in a ratio of 32:1 for the model. This means that for every 32 units in the model, there is one unit in the real rollercoaster. Therefore, we can say that the horizontal length of the real rollercoaster is 32 times the horizontal length of the model rollercoaster.

That is:h(real) = 32h(model)Similarly, the vertical height of the real rollercoaster is 32 times the vertical height of the model rollercoaster. That is:v(real) = 32v(model)

The tangent of an angle equals the vertical height divided by the horizontal distance. Therefore, the tangent of the real angle equals the tangent of the model angle times the scale factor.

That is:tanθ(real) = 32tanθ(model)By substitution,θ(real) = arctan(32tanθ(model))For the given model angle of 110°,

the corresponding real angle is:θ(real) = arctan(32tan110°)θ(real) = arctan(32(-2.74747741945462))θ(real) = arctan(-87.91927694142864)θ(real) ≈ -89.998°

The negative sign indicates that the angle is measured below the horizontal line.
