The tuition is an illustration of a linear function.

The cost of tuition and fees in the academic year 2023-2024, is $12260

Let the number of academic years after 2014-2015 academic year be x.

So, we have:

\(\mathbf{(x,y) \to (0,9200)(5,10900)}\)

A linear function is represented as:

\(\mathbf{y = mx + b}\)

Where m represents the slope (i.e. constant rate), and b represents the y-intercept (i.e. the value of y when x = 0)

So, we have:

\(\mathbf{10900 = 5m + 9200}\)

Subtract 9200 from both sides

\(\mathbf{1700 = 5m}\)

Divide both sides by 5

\(\mathbf{340 = m}\)

So, we have:

\(\mathbf{m =340 }\)

The function becomes

\(\mathbf{y = mx + b}\)

\(\mathbf{y = 340x + 9200}\)

In the academic year 2023-2024, x = 9.

So, we have:

\(\mathbf{y = 340x + 9200}\)

\(\mathbf{y = 340 \times 9 + 9200}\)

\(\mathbf{y = 3060 + 9200}\)

\(\mathbf{y = 12260}\)

Hence, the cost of tuition and fees is $12260

Answer:

m(∠W) = 114°

Step-by-step explanation:

By the property of a parallelogram,

"Opposite angles of a parallelogram are equal in measure"

By this property,

m(∠W) = m(∠U)

9x + 15 = 4 + 10x

15 - 4 = 10x - 9x

x = 11

Therefore, m(∠W) = 9x + 15

                              = 9(11) + 15

                              = 99 + 15

                              = 114°

Measure of angle W is 114°.

Answer:

\(a^2+3\,a\,b-5\,a\,b-15\,b^2=(a-5\,b)\,(a+3\,b)\)

Step-by-step explanation:

Work via factoring by groups:

!) re arrange the terms as follows:

\(a^2-5ab+3ab-15b^2\)

then extract the common factor for the first two terms (a), and separately the common factors for the last two terms (3 b):

\(a^2-5ab+3ab-15b^2\\a\,(a-5\,b)+3\,b\,(a-5\,b)\)

Now notice that the binomial factor (a-5 b) is in both expressions, so extract it:

\(a\,(a-5\,b)+3\,b\,(a-5\,b)\\(a-5\,b)\,(a+3\,b)\)

which is the final factorization.

Answer:

A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.

The linear equation is given as,

y = mx + c

Where m is the slope of the line and c is the y-intercept of the line.

A red candle has an 8-inch height and burns at a 7/10-inch per hour rate. A 6-inch tall blue candle burns at a rate of 1/5 inch per hour.

Let x be the number of hours and y be the height.

y = -0.70x + 8           ...1

y = -0.20x + 6             ...2

From equations 1 and 2, then we have

- 0.20x + 6 = - 0.70x + 8

(0.70 - 0.20)x = 8 - 6

0.50x = 2

x = 4 hours

Answer:

B

Step-by-step explanation:

a. If an element is not in set B, then it is not in set A.

b. Since we are assuming t∈T, if we can show that t∉W, then we have a contradiction.

(a) The contrapositive of the statement "If x∈A then x∈B" can be written as "If x∉B then x∉A."

(b) To prove that t∈S, we can assume the opposite, which is t∉S. Since S∩T⊂W, this means that if an element is in both sets S and T, then it is also in set W.

Using a proof by contradiction, we assume that t∉W. Since t∈T and S∩T⊂W, this means that t∈S. But this contradicts our initial assumption that t∉S. Therefore, our assumption that t∉W must be incorrect.

Hence, we can conclude that t∈S.

The probability that the second card is a jack given that the first card was a 2 is 52/51.

To calculate the probability that the second card is a jack given that the first card was a 2, we need to consider the remaining cards in the deck after the first card is drawn.

When the first card is drawn and it is a 2, there are 51 cards remaining in the deck, out of which there are 4 jacks.

The probability of drawing a jack as the second card, given that the first card was a 2, can be calculated using conditional probability:

P(Second card is a jack | First card is a 2) = P(Second card is a jack and First card is a 2) / P(First card is a 2)

Since the first card is already known to be a 2, the probability of the second card being a jack and the first card being a 2 is simply the probability of drawing a jack from the remaining 51 cards, which is 4/51.

The probability of the first card being a 2 is simply the probability of drawing a 2 from the initial deck, which is 4/52.

P(Second card is a jack | First card is a 2) = (4/51) / (4/52)

Simplifying the expression:

P(Second card is a jack | First card is a 2) = (4/51) * (52/4)

P(Second card is a jack | First card is a 2) = 52/51

(i) A = 3, B = 2, C = -1. (ii) The missing terms in the boxes are B/(x - 1) and C/(x + 1), respectively. To determine the values of A, B, and C, we need to perform partial fraction decomposition on the rational expression.

The given expression is (6x² - 14x - 4) / (2x³ - 2x). We can start by factoring the denominator, which gives us 2x(x - 1)(x + 1). Using partial fraction decomposition, we assume that the expression can be written as A/(x) + B/(x - 1) + C/(x + 1), where A, B, and C are constants. Now we can find the values of A, B, and C by equating the numerator of the original expression to the sum of the numerators in the partial fraction decomposition. This gives us 6x² - 14x - 4 = A(x - 1)(x + 1) + B(x)(x + 1) + C(x)(x - 1).

To solve for A, we let x = 0 and simplify the equation to get -4 = -A. Therefore, A = 4. For B, we let x = 1 and simplify the equation to get -12 = 2B. Thus, B = -6. Finally, for C, we let x = -1 and simplify the equation to get -16 = 2C. Hence, C = -8.

Therefore, the missing terms in the boxes are B/(x - 1) = -6/(x - 1) and C/(x + 1) = -8/(x + 1), respectively.

The coordinates of vertex C are (1, -4, -5) and the area of the parallelogram 756 is 8.71 square units.

(a) We need to find the coordinates of vertex C. Use the fact that opposite sides of a parallelogram are parallel and equal in length. We can obtain the coordinates of vertex C. It will be obtained by adding the displacement vectors of AB and AD to the coordinates of vertex A.

Displacement vector AB = = (3 - (- 1), - 2 - 2, - 4 - (- 1))

= (4, - 4, - 3)

Displacement vector AD = (- 3 - (- 1), 0 - 2, - 2 - (- 1))

= (- 2, - 2, - 1)

Coordinates of vertex C = Coordinates of vertex A + Displacement vector AB + Displacement vector AD,

= (-1, 2, -1) + (4, -4, -3) + (-2, -2, -1)

= (-1 + 4 - 2, 2 - 4 - 2, -1 - 3- 1)

= (1, -4, -5)

Coordinates of vertex C are (1, -4, -5).

(b) We have to find the area of the parallelogram. We can calculate the magnitude of the cross product of vectors AB and AD.

Cross product AB x AD = |i j k|

|4 -4 -3|

|-2 -2 -1|

= (-8i - 6j + 8k) - (-6i - 8j - 4k) + (-8i - 6j + 2k)

= -2i - 6j + 6k

Magnitude of this cross product.

|AB x AD| = √(4 + 36 + 36)

= √(4 + 36 + 36)

= √(76)

= 2 × √(19)

= 8.71 square units.

So area of parallelogram ABCD is 8.71 square units.

Answer:

  8.5 years

Step-by-step explanation:

You want to know the number of years until 18500 depreciates to 9100 at the rate of 8% per year.

The depreciation rate given as a percentage of current value tells you the depreciation is exponential. The formula will be ...

  value = (initial value) × (1 - (depreciation rate))^t

where the rate is "per year" and t is in years.

  value = 18500·(1 -0.08)^t

  9100 = 18500·0.92^t . . . . fill in the value of interest

  9100/18500 = 0.92^t . . . . divide by 18500

  log(91/185) = t·log(0.92) . . . . take logarithms

  t = log(91/185)/log(0.92) ≈ -0.3081/-0.03621 ≈ 8.509

It will be about 8.5 years until the value is $9100.

A rectangle in Euclidean plane geometry is a quadrilateral with four right angles. You might also describe it as follows: a quadrilateral that is equiangular, which indicates that all of its angles are equal. The parallelogram might also have a straight angle. Squares are rectangles with four equally sized sides. A quadrilateral of the shape of a rectangle has four 90-degree vertices and equal parallel sides. As a result, it is sometimes referred to as an equirectangular rectangle. Because its opposite sides are equal and parallel, a rectangle is also known as a parallelogram.

Given that the length of the rectangular space is three times its breadth

The chamber has a 56-meter perimeter.

Assume that the room's width is x.

As a result, the room is three times as long.

The room's perimeter is now equal to 2(3x + x).

\(Here, 2(3x + x) = 56\\ 2 * 4x = 56\\ 8x = 56\\ x = 7.\)

In each cell, the first number represents Anna's payoff, and the second number represents Brian's payoff.

(b) To find all pure best response equilibria (BNE), we need to examine each player's strategy and determine if they have a best response to the other player's strategy.

For Anna:

If Brian bids 100, Anna's best response is to bid 200, as this guarantees a higher payoff of 300.

If Brian bids 200, Anna's best response is to bid 100, as this guarantees a higher payoff of 300.

For Brian:

If Anna bids 100, Brian's best response is to bid 200, as this guarantees a higher payoff of 0.

If Anna bids 200, Brian's best response is to bid 100, as this guarantees a higher payoff of 0.

Therefore, the pure best response equilibria (BNE) of this game are:

(Anna: 200, Brian: 100)

(Anna: 100, Brian: 200)

In both cases, both players are playing their best response to the other player's strategy, resulting in a Nash equilibrium.

In terms of relative growth rate Exponential growth is characterized by a constant relative growth rate.

Exponential growth is the process of increasing quantity over time. Occurs when the instantaneous rate of change of a quantity over time is proportional to the quantity itself. The exponential growth model has the form

y (t) = C eᵏᵗ, where k is the rate constant.

Relative Growth Rate:Relative growth rate (RGR) is the rate of growth relative to size. That is, the rate of growth per unit time relative to the size at that point in time and y'(t)/y(t) is the relative growth rate of a function y at time t.

1/y dy/dt = 1/y d(C eᵏᵗ)/dt

= 1/y(kC eᵏᵗ)

= 1/y ( ky) ( since, y (t) = C eᵏᵗ)

= k

D. The relative growth rate is constant.

Answer:

y= 2x + 3

Step-by-step explanation:

To have a parallel line they need to have the same slope.

Then you need to plot the point (2,7).

A slope of 2x means that it goes up 2 y values for every x value it goes up by. So to find the y-intercept, you need to go down 2 x values. Meaning you need to subtract 4 y values. (0,3).

y= (slope) + y-intercept

Answer:

y = 2x + 3

Step-by-step explanation:

1. Approach

The line y = 2x -1 is written in slope-intercept form, essentially; y = mx + b, where "m" is the slope, and "b" is the y-intercept. If two lines are parallel, then they both have the same slope. So one simply has to substitute in a point on the line to find out what the y-intercept is, and assemble the equation.

2. Slope

As mentioned above, two parallel lines have the same slope. Hence the slope of the line that one is trying to find the equations of is 2.

3. y-intercpet

Substitute in the point that is given, and solve for the y-intercept.

y = mx + b

y = 2x + b

7 = 2(2) + b

7 = 4 + b

3 = b

4. Assembling what one knows

The equation of the line is;

y = 2x + 3

Were 2 is the slope, and 3 is the y-intercept.
