a college graduates by a factor of 1.045 every year since 1999. in 1999 924 student graduated approximately how many students will graduate in 2014​

Answers

Answer:

1788

Step-by-step explanation:

The number of students who graduates from college is multiplied by a factor of 1.045 every year since 1999.

So, the number of students graduated every year can be modeled as

[tex]G(x) = 924(1.045)^{x}[/tex] where x is the number of the year since 1999.

Now, in 2014, the x value is (14 + 1) = 15 years.

So, the number of students who will graduate in 2014 is given by

[tex]G(15) = 924(1.045)^{15} = 1788.2[/tex] ≈ 1788. (Answer)


The running back for the Bulldogs football team carried the ball 5 times for a total loss of 11 1/4 yards. Find the average change in field position on each run. Enter the average change as a simplified mixed number.


Answers

Answer:

[tex]\displaystyle 2\ \frac{1}{4}[/tex]

Step-by-step explanation:

Fractions

They can be expressed as proper fractions, improper fractions or mixed numbers. Proper fractions are such that the numerator is less than the denominator, like 2/5, 7/11, -9/10. Improper fractions are those whose numerators are greater than the denominator, such as 5/3, 10/9, -21/8.  

Mixed numbers are expressions made of whole numbers and a proper fraction, like 4 3/5, 1 1/2, -5 4/9. Mixed numbers can be transformed to improper fractions and vice-versa.

The question requires us to find the average change in field position on each run of the running back for the Bulldogs football team which carried the ball 5 times for a total loss of 11 1/4 yards.

The number 11 1/4 is mixed, to express it as an improper fraction, we add the numbers like

[tex]\displaystyle 11+\frac{1}{4}=\frac{45}{4}[/tex]

This improper fraction will now be divided by 5 to find the average of 5 runs:

[tex]\displaystyle \frac{\frac{45}{4}}{5}=\frac{9}{4}[/tex]

We now need to separate the improper fraction to a mixed number, let's just divide 9 by 4 to get 2 as the quotient and 1 for the remainder, thus

[tex]\boxed{\displaystyle \frac{9}{4}=2\ \frac{1}{4}}[/tex]

Answers

The reflection transformation of the triangles is C) [tex]( rx-axis(x, y) \rightarrow (x, -y) )[/tex].

The points of the original triangle are:

M (-5, 4) N (-2, 3) L (-4, 2)

The points for the reflected triangle are:

L' (-4, -2) M' (-5, -4) N' (-2, -3)

Identify the transformation

From the pairs of coordinates, we can observe how each point has changed from the original triangle to the reflected triangle:

M (−5, 4) was reflected to M' (−5, −4). N (−2, 3) was reflected to N' (−2, −3). L (−4, 2) was reflected to L' (−4, −2).

Analyze the change in coordinates

We see that for each point, the x-coordinates remain unchanged while the y-coordinates change sign from positive to negative. This indicates that the reflection is across the x-axis.

Reflection rule

The general rule for reflection across the x-axis can be stated as follows:

If a point is given by (x, y), then the reflected point will be (x, -y).

The common ratio is not the same for all pairs of consecutive terms, so the sequence is not geometric.

To determine if a sequence is geometric, we need to check if there is a common ratio between consecutive terms.

In a geometric sequence, each term is obtained by multiplying the previous term by a constant value called the common ratio.

Let's check the given sequence: -1, 1, 4, 8.

To find out if it is geometric, we need to check if the ratio of consecutive terms is constant:

Common Ratio (r) = (Second Term) / (First Term)

= 1 / (-1)

= -1

Now, let's check if the common ratio is the same for the other pairs:

1st and 2nd terms: 1 / (-1) = -1

2nd and 3rd terms: 4 / 1 = 4

3rd and 4th terms: 8 / 4 = 2

The common ratio is not the same for all pairs of consecutive terms. Since the common ratio is not constant, the given sequence (-1, 1, 4, 8) is not a geometric sequence.

Write a recursive rule for the sequence.
243, 81, 27, 9, 3, ..

Answers

Final answer:

A recursive rule for the sequence 243, 81, 27, 9, 3, ... is to multiply each term by one-third (⅓) of the previous term. The first term is 243, and the rule can be expressed as an = ⅓ × an-1 for n >= 2.

Explanation:

To write a recursive rule for the sequence 243, 81, 27, 9, 3, ... we must first identify the pattern. Observing the sequence, we see that each term is one-third of the previous term. Therefore, to get from one term to the next, we multiply by ⅓ (which is the same as dividing by 3).

The recursive formula for this sequence can be written as follows:

Let the first term a1 = 243. Then for each n >= 2, an = ⅓ × an-1, where an represents the nth term of the sequence.

This recursive rule clearly indicates that every term is a fraction of the preceding term, which is consistent with the pattern of division by three observed in the original sequence.

Final answer:

The cost of one game is 1.25 dollars and the cost of one ride is 3.75 dollars at the carnival. This was determined by setting up and solving a system of equations based on the expenses of Owen and Kayden.

Explanation:

To determine the cost of each game and each ride at the carnival, we can set up a system of equations based on Owen and Kayden's expenses. Let x represent the cost of one game and y represent the cost of one ride.

Owen played 5 games and went on 6 rides for a total cost of 28.75 dollars. This can be represented by the equation:
5x + 6y = 28.75

Kayden played 4 games and went on 3 rides for a total cost of 16.25 dollars. This can be represented by the equation:
4x + 3y = 16.25

We now have a system of linear equations:
5x + 6y = 28.75

4x + 3y = 16.25

To solve the system, we can multiply the second equation by 2 to align the y-terms:
5x + 6y = 28.75

8x + 6y = 32.50
Subtracting the first equation from the multiplied second equation, we get:

3x = 3.75
Dividing both sides by 3, we find that x = 1.25, which is the cost of one game.

To find the cost of one ride, we substitute x = 1.25 into either of the original equations. If we use the second equation 4(1.25) + 3y = 16.25, we get:
3y = 16.25 - 5

3y = 11.25

y = 3.75

Therefore, the cost of one ride is 3.75 dollars.

7-4+6=7 Complete the equation to make it equal

Answers

Answer:

7-4+6=7 + 2

Step-by-step explanation:

The original equation 7-4+6=7 is incorrect because it simplifies to 9, not 7. There is no simple way to adjust the equation with the given numbers to make the equation balance correctly. It's crucial to check your work and make sure the equation balances, just like ensuring a chemical equation has equal numbers of atoms on both sides.

To complete the equation 7-4+6=7 to make it equal, we need to perform the operations on the left side of the equation and see if the result is indeed 7, the same as the right side. Let's solve it step by step:

First, subtract 4 from 7, which gives us 3.Next, add 6 to this result, which gives us 3 + 6 = 9.So, the left side of the equation is actually 7-4+6, which calculates to 9.Since 9 does not equal 7, there seems to be an error in the equation as presented.

The original equation 7-4+6=7 is incorrect because 7-4+6 equals 9, not 7. To make the equation correct, we would need to change a number or an operation. One possible solution could be adding parentheses: (7-4)+6=7+2, which simplifies to 3+6=9, but again that does not equal 7. Therefore, there is no simple way to correct the equation using basic operations without changing the numbers given.

To make sure the charge and atoms on both sides of an equation balance or to ensure the correctness of a mathematical operation, eliminating terms where possible to simplify the algebra and checking the answer to see if it’s reasonable are important steps.

When balancing equations, whether they are chemical equations or mathematical ones, it's essential to make sure each side is equal to maintain the balance, as seen in the example: 7 carbon atoms, 16 hydrogen atoms, and 22 oxygen atoms on each side of a balanced chemical equation.

what is the answer to x over 7 = 89

Notice that on the left side, the 7 and 7 cancel each other out so we're just left with x. On the right side we have

89 x 7 which is 623 so x = 623.

Finally, we can check our answer by plugging a 623 back into the original equation. So we have [tex]\frac{(623)}{7} = 89[/tex] or 89 = 89. Since this is true, our answer checks.

consider the functions given below
f(x) + -3x-5
g(x) + f(x)+9
what is the y intercept of g

Answers

Final answer:

The y-intercept of the function g(x), defined as g(x) = f(x) + 9 where f(x) = -3x - 5, is 4. This is determined by evaluating g(0), resulting in a y-intercept at the point (0, 4).

Explanation:

The question asks about finding the y-intercept of the function g(x), which is defined in terms of another function f(x). Given that f(x) is equal to -3x - 5 and g(x) equals f(x) + 9, to find the y-intercept of g(x), we substitute x with 0 in the function f(x) and then add 9. The y-intercept is the point where the function crosses the y-axis, which is when x = 0.

First, we find the value of f(0):

f(0) = -3(0) - 5 = -5

Next, we determine g(0) by adding 9 to the value of f(0):

g(0) = f(0) + 9 = -5 + 9 = 4

Therefore, the y-intercept of g(x) is 4, which means the line representing g(x) crosses the y-axis at the point (0, 4).

A sample of 60 women is obtained, and their heights ( in inches ) and pulse rates ( in beats per minute ) are measured. The linear correlation coefficient is 0.234 and the equation of the regression line is ^y= 17.5 + 0.850x, where x represents height. The mean of the 60 heights is 63.4 in and the mean of the 60 pulse rates is 75.6 beats per minute. Find the best predicted pulse rate of a woman who is 74 inches tall.

Harry drew a number line to solve a word problem A normal mode of a closed system is an oscillation of the system in which all parts oscillate at a single frequency. In general there are an infinite number of such modes, each one with a distinctive frequency fi and associated pattern of oscillation.Consider an example of a system with normal modes: a string of length L held fixed at both ends, located at x=0 and x=L. Assume that waves on this string propagate with speed v. The string extends in the x direction, and the waves are transverse with displacement along the y direction.In this problem, you will investigate the shape of the normal modes and then their frequency.The normal modes of this system are products of trigonometric functions. (For linear systems, the time dependance of a normal mode is always sinusoidal, but the spatial dependence need not be.) Specifically, for this system a normal mode is described byyi(x,t)=Ai sin(2*x/i)sin(2fi*t)A)The string described in the problem introduction is oscillating in one of its normal modes. Which of the following statements about the wave in the string is correct?The wave is traveling in the +x direction.a) The wave is traveling in the -x direction.b) The wave will satisfy the given boundary conditions for any arbitrary wavelength lambda_i.c) The wavelength lambda_i can have only certain specific values if the boundary conditions are to be satisfied.d) The wave does not satisfy the boundary condition y_i(0;t)=0.B)Which of the following statements are true?a)The system can resonate at only certain resonance frequencies f_i and the wavelength lambda_i must be such that y_i(0;t) = y_i(L;t) = 0.b) A_i must be chosen so that the wave fits exactly on the string.c) Any one of A_i or lambda_i or f_i can be chosen to make the solution a normal mode.C) Find the three longest wavelengths (call them lambda_1, lambda_2, and lambda_3) that "fit" on the string, that is, those that satisfy the boundary conditions at x=0 and x=L. These longest wavelengths have the lowest frequencies.D) The frequency of each normal mode depends on the spatial part of the wave function, which is characterized by its wavelength lambda_i.Find the frequency f_i of the ith normal mode.
