Find the maximize z = 4x + y. Subject to the constraints x + y ≤ 50, 3x + y ≤ 90, x,y ≥ 0
The maximum value of z = 4x + y subject to the given constraints is 180, which occurs at x = 45 and y = 0.
How to deal with inequality?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.

Determine if the function below is continuous.
A. not continuous
B. both continuous and not continuous
C. cannot be determined
D. continuous
A. not continuous
Step-by-step explanation: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.
Figure A is a scale image of figure b as shown the scale that maps figure a onto figure b is 1:1 3/4
The value of x is 21.75.
We need to convert from mixed number to decimal number. To do this you can follow the steps shown below:
We must divide the numerator of the fraction by the denominator of the fraction.
Now we must add the quotient obtained to the Whole number part.
So, we get:
7 1/4 = 7.25
Then, the scale image that maps "Figure a" onto "Figure b" is: 1 : 7.25.
Finally, in order to find the value of "x", you need to multiply the given length of the corresponding side of "Figure a" by 7.25,
Therefore, you get that the result is:
x = 3(7.25)
x = 21.75

Which choice is equivalent to the product below when x≥ 0?
√10x² √5x
A. 5x√2x
B. x√15
C. √15x²
D. 5x√2
SUBMIT
Answer:
Step-by-step explanation:
We can simplify the given product using the properties of radicals:
√10x² √5x = √(10*5)x^(2+1) = √50x^3
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.

f(x)= 2x^3-3x^2-12x+1
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
How can we use the derivative of a function to analyze a car's motion?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.

The population will be approximately people.
(Do not round until the final answer. Then round to the nearest whole number as needed.)
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)

What is a linear equation and examples?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

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

c. Symmetric with respect to the origin
Answer:
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.

1. A cart moving at 20 m/s is brought to a stop by the force plotted in the force-time graph shown here. Find the impulse and the approximate mass of the cart. Show all your work.
The required value of impulse is 88 N-s and the mass of the cart is 8.8 kg.
How to find the impulse?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.

2. The mean for you = 14.25 and your friend 31.3. This means that your friend has a higher mean than you. The median for you is 11 and your friend is 30.5. Given that both the mean and median of your friend is higher than yours, it means that your friend mowed more lawns than you
3. The range of data for you is 26 and for your friend is 21.
How do you find the mean, median and range?To find the mean for each data set, add all the number together and divide it by the set number. For example;
4 + 5 + 7 + 8 + 10 + 12 + 12 + 17 + 20 + 21 + 25 + 30
= 171 / 12
= 14.25
To find the range for the data set, simply take the highest number of a set and minus it by the lowest number. For Example;
For your data set, it is 30 - 4 = 26
To find the median for the data sets, simply look for the number in the middle. However, in your data set, there are two middle numbers. take the sum of the two numbers and divide it by 2.
(10 + 12) / 2 = 11

An individual depositing in a non-IRA account has to pay income taxes on the funds deposited and on interest earned in each year but does not have to pay taxes on withdrawals from the account.
Sarah, who is five years from retirement, receives a $10,000 bonus at work. She is trying to decide whether to save this extra income in an IRA account or in a regular savings account. Both accounts earn 8 percent nominal interest, and Sarah is in the 30 percent tax bracket in every year (including her retirement year)
If Sarah invests in the normal savings account, her net value (after taxes) five years from now will be?:
After five years, her IRA account's net worth (after taxes) will indeed be $14,322.88 ($10,000 + $4,322.88).
What do you mean by interest earned?Sarah will be required to file taxes just on interest received each year if she places the $10,000 inside a standard savings account, which will lower her net worth.
She will have earned $800 in pre-tax interest every year, assuming she receives nominal interest of 8% annually.
She will, however, be liable for $240 in taxes just on interest generated each year (30% of $800) since she falls into the 30% tax bracket.
Her pre-tax interest earnings after five years will total $4,000 ($800 x five years). She will still have paid $1,200 in total in taxes just on interest generated ($240 x 5)
She will therefore have a net worth of $12,800 ($10,000 + $4,000 - $1,200) in the normal savings account after five years (after taxes).
Sarah won't have to pay taxable income on the $10,000 invested in such an IRA account or the interest accrued until she starts taking distributions in retirement.
She will have earned $800 in pre-tax interest every year, assuming she receives nominal interest of 8% annually.
She will have the whole $800 to reinvest & compound each year, though, as she is not subject to income taxation on the interest gained each year.
She will have earned $4,322.88 in pre-tax interest after five years, and she won't have to pay any taxes until she starts taking withdrawals in retirement.
