The slope from the table is greater than the slope from the graph hence the table shows a greater rate.

The slope of a graph is the measure of how steep a line is. It is the ratio of the vertical change (rise) to the horizontal change (run) between any two points on the line. Mathematically, slope is represented as:

Slope (m) = (change in y)/(change in x)

The slope from the table is;

A. not continuous

Continuous functions have no jumps or vertical asymptotes.

Continuity

For a function to be continuous, each point on the function must be defined. This means that there cannot be points on the graph where there is no value or coordinate point. Additionally, all points must be connected by the graph. Sudden jumps in the graph that are not connected by anything are not continuous.

Determining Continuity

The graph above is not continuous. We know this for 2 reasons. Firstly, the graph is not defined at x = -3. Since there is an open circle at x = -3, the value is not defined. Thus, the function cannot be considered continuous. Additionally, there are multiple jumps. At x = -3, the function suddenly jumps to x = -2 without the points being connected. The same thing happens again at x = 1. This also shows that the graph is not continuous.

The maximum value of z = 4x + y subject to the given constraints is 180, which occurs at x = 45 and y = 0.

To find the maximum value of z = 4x + y subject to the given constraints, we can use linear programming.

Graph the constraints:

First, we will graph the constraints to visualize the feasible region.

The constraint x + y ≤ 50 represents the region below the line x + y = 50:

The constraint 3x + y ≤ 90 represents the region below the line 3x + y = 90:

The feasible region is the shaded region that satisfies both constraints:

Identify the corner points of the feasible region:

The feasible region has four corner points: (0, 0), (0, 50), (30, 20), and (45, 0).

Evaluate z at each corner point:

z(0, 0) = 4(0) + 0 = 0

z(0, 50) = 4(0) + 50 = 50

z(30, 20) = 4(30) + 20 = 140

z(45, 0) = 4(45) + 0 = 180

Compare the values of z at the corner points:

The largest value of z is 180, which occurs at the corner point (45, 0).

Therefore, the maximum value of z = 4x + y subject to the given constraints is 180, which occurs at x = 45 and y = 0.

To calculate the base area of the paperweight, we can use the formula for the volume of a three-dimensional object:

Volume = Base area x Height

In this case, we know that the height of the paperweight is 4cm and the volume is 38.4 cubic cm.

So we can rearrange the formula and solve for the base area:

Base area = Volume / Height

Substituting the values we have:

Base area = 38.4 cubic cm / 4cm

Base area = 9.6 square cm

Therefore, the base area of the paperweight is 9.6 square cm.

what is expression ?

It is possible to do mathematical operations like addition, subtraction, division, and multiplication. An expression is put together as follows: Number, expression, and mathematical operator.

a) f(x) + xg(x)

First, we need to find xg(x), which is x multiplied by g(x):

[tex]xg(x) = x(x^{2} + 5x + 2) = x^{3} + 5x^{2} + 2x\\\\f(x) + xg(x) = 2x^{2} - x - 4 + x^{3} + 5x^{2} + 2x\\\\f(x) + xg(x) = x^{3} + 7x^{2} + x - 4[/tex]

Therefore, [tex]f(x) + xg(x) = x^{3} + 7x^{2} + x - 4.[/tex]

b) [f(x)]²

To square f(x), we can simply multiply it by itself:

[f(x)]² = (2x² - x - 4)(2x² - x - 4)

[tex][f(x)]² = 4x^{4} - 4x^{3} - 15x^{2} + 8x + 16[/tex]

c) f²(x)

Since f²(x) means f(x) times f(x), we can use the distributive property of multiplication:

[tex]f^{2} (x) = f(x) * f(x)\\\\f^{2}(x) = (2x^{2} - x - 4)(2x^{2} - x - 4)[/tex]

[tex]f^{2}(x) = 4x^{4} - 4x^{3} - 15x^{2} + 8x + 16[/tex]

To find gf(x), we need to multiply g(x) by f(x):

[tex]gf(x) = (x^{2} + 5x + 2)(2x^{2} - x - 4)[/tex]

Multiplying each term of g(x) by each term of f(x), and simplifying:

gf(x) = 2x⁴ + 8x³ - 13x² - 3x - 8

Answer: the correct answer is B

Step-by-step explanation:

Remember that the coordinates (4,4π3) tell us the radius r=4 and the angle θ=4π3. So the point should be on the circle labeled 4 and form an angle of 4π3 with the positive x-axis. Point B is the correct point.

 The third player hit 4 more home runs than the first player. The algebraic expression that shows the relationship between a and b is:  a = 3b. So option A is correct

A linear equation in one variable is an equation that has only one variable. It is of the form Ax B = 0, where A and B are  two real numbers and x is an unknown variable with only one solution. For example, 9x + 78 = 18 is a linear equation in one variable.

 2) Each player's home runs are labeled A, B, C, and D, where A is the first baseman, B is the second baseman, C is the third baseman, and D is the shortstop. We know this:

C = 2B (the third player hit twice as many home runs as the second player)

C/B = D/B = A/C (numbers for first baseman and shortstop are proportional to numbers for third baseman and second baseman)

B = D 4 (second baseman hit 4 more home runs than  shortstop)

To solve for the values ​​of A, B, C, and D, we can use the second equation to write:

C/B = D/B

C = D (multiply both sides by B)

C = B - 4 (using the fourth equation to substitute  D)

2B = B - 4 (using the first equation to substitute  C)

B = 4 (interface to both sides 4)

C = 8 (using the first equation to find C)

D = 4 (using the fourth equation to find D)

A = C/2 = 4 (use another equation to find A)

Therefore the third player (C) hit 8 home runs and the first player (A) hit 4 home runs, so the third player hit 4 more home runs than the first player.

3) The relative relationship between a and b can be expressed as follows:

a/b = 6/2 = 3/1

To write this relationship as an algebraic equation, we can cross multiply to get:

a = 3b

Therefore, the algebraic expression that shows the relationship between a and b is:

a = 3b. So option A is correct

Answer:  formula 9x - 5y = -160 is not a direct variation.

Step-by-step explanation: The provided expression, 9x - 5y = -160, does not exemplify direct variation.

Direct variation is a correlation existing between two variables, wherein one is a constant scalar multiple of the other. Stated differently, should one variable increase by a defined magnitude, the corresponding variable will also experience a commensurate increase of identical magnitude.

The formula provided indicates the absence of a constant proportionality between the temperature in degrees Celsius (x) and the temperature in degrees Fahrenheit (y). It is noteworthy that the correlation amidst the variables x and y is non-linear in nature, thereby precluding its representation in the form of a direct proportionality.

Answer: It is not a direct variation.

Step-by-step explanation:

         While a linear equation is a direct variation, the y-intercept of a direct variation relationship must be 0. Here, that is not the case. Let us manipulate this equation into a slope-intercept equation.

Given:

   9x - 5y = -160

The population will be approximately 29,628 people 5 years from now. (Rounded to the nearest whole number)

To calculate the future population, we need to take into account the growth rate over time.

In this case, we know that the population doubled in size over 26 months and the current population is 20,000.

Let's break down the problem step by step:

Calculate the monthly growth rate:

Since the population doubled in size over 26 months, the monthly growth rate can be calculated as the 26th root of 2.

This is because if the population doubles in size over 26 months, each month the population grows by the 26th root of 2.

Monthly growth rate  [tex]= 2^{(1/26) } \approx 1.027[/tex]

Calculate the number of months in 5 years:  

Since there are 12 months in a year, the number of months in 5 years is [tex]5 \times 12 = 60[/tex] months.

Calculate the future population:

We start with the current population of 20,000 and apply the monthly growth rate for 60 months.

Future population  = Current population [tex]\times[/tex]  (Monthly growth rate)^{(Number of months)

Future population [tex]= 20,000 \times (1.027)^60 \approx 29,628.12[/tex]

Suppose you are driving a car with the velocity function represented by the following equation: f(x)= 2x^3-3x^2-12x+1. The derivative would be: f'(x) = 6x^2 - 6x - 12

To find the acceleration of the car at a particular moment, we would need to calculate the derivative of the velocity function f(x). In this case, the derivative would be:

f'(x) = 6x^2 - 6x - 12

The result of this calculation would give us the instantaneous acceleration of the car at a given time x.

In terms of the car's motion, a positive value for f'(x) would indicate that the car is accelerating, while a negative value would indicate that the car is decelerating. The magnitude of the value would indicate the rate of change of the car's velocity, with larger values indicating a more rapid change.

To determine if the given equations are symmetric with respect to the origin, we need to check if replacing x with -x and y with -y results in the same equation.

For the equations given:

y=7x-4 is not symmetric with respect to the origin since replacing x with -x and y with -y gives y=-7x+4, which is not the same equation.

y= -x+7 is not symmetric with respect to the origin since replacing x with -x and y with -y gives y=x-7, which is not the same equation.

y = -7x^2 is symmetric with respect to the origin since replacing x with -x and y with -y gives -y = -7(-x)^2, which simplifies to -y = -7x^2. Thus, the equation remains the same.

y = 6x^2 - 9 is not symmetric with respect to the origin since replacing x with -x and y with -y gives -y = 6(-x)^2 - 9, which simplifies to -y = 6x^2 - 9. Thus, the equation is not the same.

x=1/4 y^2 is not symmetric with respect to the origin since replacing x with -x and y with -y gives -x = 1/4 (-y)^2, which simplifies to -x = 1/4 y^2. Thus, the equation is not the same.

x = -y^2 + 9 is symmetric with respect to the origin since replacing x with -x and y with -y gives -x = -(-y)^2 + 9, which simplifies to -x = -y^2 + 9. Thus, the equation remains the same.

y=-1/6 x^3 is symmetric with respect to the origin since replacing x with -x and y with -y gives -y=-1/6(-x)^3, which simplifies to -y=-1/6 x^3. Thus, the equation remains the same.

y=x^3-1 is not symmetric with respect to the origin since replacing x with -x and y with -y gives -y=(-x)^3-1, which simplifies to -y=-x^3-1. Thus, the equation is not the same.

y=sqrt(x) is not symmetric with respect to the origin since replacing x with -x and y with -y gives -y=sqrt(-x), which is not the same equation.

y=sqrt(x)-6 is not symmetric with respect to the origin since replacing x with -x and y with -y gives -y=sqrt(-x)-6, which is not the same equation.

Therefore, the only equation that is symmetric with respect to the origin is y = -7x^2.

The required value of impulse is 88 N-s and the mass of the cart is 8.8 kg.

Newton's Second Law relates an object's acceleration as a function of both the object's mass and the applied net force on the object.

Given data:

The speed of cart is, v = 10 m/s.

We are given the Force-time graph for which the area of the force-time graph will provide the value of impulse. So from the graph, the maximum force is,

F = 22 N

And time interval is,

t = 4.5 s - 0.5 s

t = 4 s

So, the impulse is,

I = Area of graph

I = F × t

I = 22 × 4

I = 88 N-s

Now the standard expression for the impulse as per the impulse-momentum theorem is,

I = ΔP (Change in momentum)

I = m ×( v - u )

Here, u is the final velocity, and since the cart stops finally, then u = 0 m/s. And m is the mass of the cart.

Solving as,

88 = m ×( v - u )

88 = m ×( 10 - 0 )

m = 8.8 kg

Thus, we can conclude that the required value of impulse is 88 N-s and the mass of car is of 8.8 kg.

We can further simplify the radical by factoring out the largest perfect square from 50, which is 25:

√50x^3 = √(25*2)x^3 = 5x√2

Therefore, the product √10x² √5x is equivalent to 5x√2, when x≥0.

To simplify the product √10x² √5x, we can combine the square roots and simplify:

√10x² √5x = √(10x² * 5x) = √(50x³) = √(25x² * 2x) = 5x√2x

Therefore, the choice that is equivalent to the original product when x≥0 is A. 5x√2x.
