The solution to the compound inequality 3u-2<=-14 or 4u+4<28 is u<=-4 or u<6.
Determine the compound inequalityA compound inequality is an equation that combines two inequalities with the word "and" or "or".
To solve a compound inequality, we need to solve each inequality separately and then combine the solutions.
For the compound inequality 3u-2<=-14 or 4u+4<28, we will solve each inequality separately.
First, we will solve 3u-2<=-14: 3u-2<=-14 3u<=-14+2 3u<=-12 u<=-4
Next, we will solve 4u+4<28:
4u+4<28 4u<28-4 4u<24 u<6
Now, we will combine the solutions.
Since the word "or" is used in the compound inequality, the solution is the union of the two solutions. This means that the solution is any value of u that satisfies either inequality.
The solution is u<=-4 or u<6. This can also be written in interval notation as (-∞,-4] U (-∞,6).
So, the solution to the compound inequality 3u-2<=-14 or 4u+4<28 is u<=-4 or u<6.

(x+4)^2=15
solving by talking the square root
Answer:
x = -4 + √15 and x = -4 - √15.
Step-by-step explanation:
To solve for x in the equation (x + 4)^2 = 15 using square roots, we can take the square root of both sides of the equation, remembering to include both the positive and negative square root:
(x + 4)^2 = 15
Taking the square root of both sides:
±(x + 4) = √15
Now we can isolate x by subtracting 4 from both sides of the equation:
x + 4 = ±√15
x = -4 ±√15
Therefore, the solutions to the equation (x + 4)^2 = 15 are x = -4 + √15 and x = -4 - √15.
Please explain this more in depth. How does the chain rule allow
the first equation to reduce to the second equation? Some simple
explanation of the chain rule would also be helpful.
The chain rule allows us to reduce the first equation to the second equation by finding the derivative of the composite function and substituting it for the original function. This provides a simpler and more concise explanation of the relationship between the two equations.
The chain rule is a formula for calculating the derivative of a composite function. It states that the derivative of a composite function f(g(x)) is equal to the derivative of f with respect to g times the derivative of g with respect to x. In mathematical notation, this is expressed as (f(g(x)))' = f'(g(x)) * g'(x).
In the case of the first equation, we can use the chain rule to reduce it to the second equation by applying the formula mentioned above. First, we need to identify the composite function and its components. In this case, the composite function is f(g(x)) and the components are f and g.
Next, we need to find the derivative of f with respect to g and the derivative of g with respect to x. Once we have these derivatives, we can multiply them together to get the derivative of the composite function.
Finally, we can reduce the first equation to the second equation by substituting the derivative of the composite function for the original composite function. This will give us the second equation, which is a simplified version of the first equation.
In conclusion, the chain rule allows us to reduce the first equation to the second equation by finding the derivative of the composite function and substituting it for the original function. This provides a simpler and more concise explanation of the relationship between the two equations.

Two circles inside a square are externally tangent to each other and are tangent to certain sides of the square as shown. The perimeter of the square is $2+\sqrt 2.$ What is the sum of the circumferences of the two circles?
The sum of the circumferences of the two circles is equal to [tex]$2\pi \sqrt 2.$[/tex]
What is circumferences?Circumference is the distance around a two-dimensional shape, such as a circle or ellipse. It can be calculated by multiplying the circumference of the shape by its diameter. The formula for calculating the circumference of a circle is 2πr, where π is the constant 3.14 and r is the radius of the circle. The circumference of an ellipse is more complicated and requires knowledge of the length of its major and minor axes.
The two circles are externally tangent to each other, which means that the distance between them is equal to the sum of their radii. Since the circles are tangent to the sides of the square, the length of one side of the square is equal to the sum of their radii. Since the perimeter of the square is given to be [tex]$2+\sqrt 2,[/tex] we can calculate the length of each side of the square to be [tex]$\sqrt 2.$[/tex] Hence, the sum of the radii of the two circles is equal to [tex]$\sqrt 2.$[/tex]

function. Find ????(????|???? = y)
The conditional density function ????(????|???? = y) = 1/y. This is a valid density function because it is non-negative and integrates to 1.
So the answer is ????(????|???? = y) = 1/y.
The question asks us to find the conditional density function ????(????|???? = y) given the joint density function ????(x, y) = 6y(1 − y), 0 ≤ x ≤ y ≤ 1.
To find the conditional density function, we need to divide the joint density function by the marginal density function of y.
The marginal density function of y can be found by integrating the joint density function with respect to x:
????(y) = ∫????(x, y) dx = ∫6y(1 − y) dx = 6y(1 − y) ∫dx = 6y(1 − y) (x) |0≤x≤y = 6y(1 − y) (y - 0) = 6y^2(1 − y)
Now we can find the conditional density function by dividing the joint density function by the marginal density function:
????(????|???? = y) = ????(x, y)/????(y) = 6y(1 − y)/6y^2(1 − y) = 1/y
Therefore, the conditional density function ????(????|???? = y) = 1/y. This is a valid density function because it is non-negative and integrates to 1.

The total of monthly payments for a 4-year loan is $4,200. 0. The APR is 9. 25%. How much money was originally borrowed?
The original amount borrowed was approximately $34,211.1.
To compute the first sum acquired, we can involve the recipe for the current worth of a customary annuity, which addresses a progression of equivalent installments made toward the finish of every period. The recipe is:
PV = [tex]PMT * (1 - (1 + r)^{(-n)}) / r[/tex]
where PV is the present value, PMT is the payment amount, r is the interest rate per period, and n is the total number of periods.
In this case, we have monthly payments, so we need to convert the APR to a monthly interest rate by dividing it by 12. We also have a 4-year loan, which means 48 monthly payments.
APR = 9.25%
Monthly interest rate = APR / 12 = 0.0925 / 12 = 0.00771 (rounded to five decimal places)
Total number of payments = 48
Total amount of payments = $4,200.0
Substituting these values into the formula, we get:
PV =[tex]PMT * (1 - (1 + r)^{(-n)}) / r[/tex]
PV = [tex]$4,200.0 * (1 - (1 + 0.00771)^{(-48)}) / 0.00771[/tex]
PV = $4,200.0 x (1 - 0.5180) / 0.00771

A store is having a holiday sale and offers no down payment on each credit items. A sound system will cost $29.99 per week for a year. What is the total price?
Answer:$20.40
Step-by-step explanation:
20% off means that the new price of the skirt will be 80% of the original price:
$30(100% – 20%) = $30(80%)
Converting the percent to a decimal gives:
$30(0.8) = $24.00
There is an additional 15% off the sale price of $24.00, so the final price is 85% of the sale price:
$24(100% – 15%) = $24(85%)
Again converting the percent to a decimal gives:
$24(0.85) = $20.40
Shea runs a carpet cleaning business. The average cost to shea per cleaning is $30. Shea charges $60 per cleaning. Shea’s fixed plus variable costs per month total $1,500. How many carpet cleaning does shea need to do per year to break even?
Shea needs to do 600 carpet cleaning per year to break even.
What is revenue?
Total revenue is the total amount of money earned by a business from the sale of its products or services during a particular period of time.
To break even, the total revenue Shea generates from the carpet cleaning business must be equal to the total cost of running the business.
Let's first calculate the total cost of running the business per year:
Total Cost = Fixed Costs + Variable Costs
Since the fixed plus variable costs per month total $1,500, the total cost per year would be:
Total Cost = $1,500 x 12
Total Cost = $18,000
Now, let's calculate the profit that Shea makes per cleaning:
Profit per Cleaning = Price per Cleaning - Cost per Cleaning
Profit per Cleaning = $60 - $30
Profit per Cleaning = $30
So, Shea makes a profit of $30 per cleaning.
To break even, the total profit generated by the number of cleanings Shea does per year should be equal to the total cost of running the business per year:
Total Profit = Total Revenue - Total Cost
If x is the number of carpet cleaning Shea needs to do per year to break even, then:
Total Revenue = Price per Cleaning x Number of Cleanings per Year = $60x
Total Profit = Profit per Cleaning x Number of Cleanings per Year = $30x
Setting Total Profit equal to Total Cost:
$30x = $18,000
x = $18,000 / $30
x = 600
Therefore, Shea needs to do 600 carpet cleaning per year to break even.

The required vertices of [tex]$\Delta A'B'C'$[/tex] are A'(-10, 15), B'(-15, -10), and C'(5, -5).
How to find the dilated coordinates of triangle?The transformation that defines AA'B'C' can be described as a dilation with center at the origin and scale factor of 5/2.
To find the coordinates of A', B', and C', we can use the following formulas:
[tex]$\begin{align*}A'(x,y) &= \left(\frac{5}{2}\right)x, \left(\frac{5}{2}\right)y \B'(x,y) &= \left(\frac{5}{2}\right)x, \left(\frac{5}{2}\right)y \C'(x,y) &= \left(\frac{5}{2}\right)x, \left(\frac{5}{2}\right)y \\end{align*}$[/tex]
Using the coordinates of A(-4,6), B(-6, -4), and C(2,-2), we can calculate the coordinates of A', B', and C' as follows:
For point A(-4,6), we have:
[tex]$A'(x,y) = \left(\frac{5}{2}\right) x, \left(\frac{5}{2}\right) y = \left(\frac{5}{2}\right) (-4), \left(\frac{5}{2}\right) (6) = (-10, 15)$[/tex]
Therefore, the coordinates of A' are (-10, 15).
For point B(-6,4), we have:
[tex]$B'(x,y) = \left(\frac{5}{2}\right) x, \left(\frac{5}{2}\right) y = \left(\frac{5}{2}\right) (-6), \left(\frac{5}{2}\right) (4) = (-15, 10)$[/tex]
Therefore, the coordinates of B' are (-15, 10).
For point C(2,2), we have:
[tex]$C'(x,y) = \left(\frac{5}{2}\right) x, \left(\frac{5}{2}\right) y = \left(\frac{5}{2}\right) (2), \left(\frac{5}{2}\right) (-2) = (5, -5)$[/tex]
the coordinates of C' are (5, -5).

1 divided by 2/6 is equal to 3.
Division is a mathematical operation used to divide one number (the dividend) by another number (the divisor) to find out how many times the divisor is contained within the dividend
To divide 1 by 2/6, we need to find out how many times the denominator (2/6) fits into the numerator (1).
One way to approach this is to convert the fraction 2/6 to an equivalent fraction with a denominator of 1. To do this, we can multiply both the numerator and denominator of 2/6 by the same number, in this case 3:
2/6 = (23)/(63) = 6/18

A rectangle has a width of 4 cm less than its length. If a new rectangle is formed by increasing the width 5 cm and decreasing the length 3 cm, the area of this resulting rectangle is 117cm^2. What are the dimensions of the original rectangle?
-- cm by -- cm?
As a result, a new rectangle is created by increasing the breadth by 5 cm, making the οriginal rectangle 12 by 8 cm in size.
What is rectangle?A rectangle is a flat, fοur-sided shape that is made by twο sets οf parallel lines at each οf its fοur right angles (angles οf 90 degrees). A rectangle's diagοnals and οppοsing sides have equal lengths and are bisected by its οppοsite sides. The perimeter οf a rectangle is equal tο the sum οf the lengths οf its fοur sides, and its area is calculated by multiplying its length by its breadth. Rectangles are frequently seen in daily living, including οn cοmputer screens, bοοk cοvers, and dοοrs and windοws.
given:
Let L represent the initial rectangle's length in centimetres.
Therefοre, the width οf the initial rectangle can be expressed as L – 4 cm, which is 4 cm less than its length.
The οriginal rectangle's area is equal tο the sum οf its length and breadth, sο:
Area οf the initial parallelοgram is equal tο L(L-4) = L2 - 4L.
The new rectangle's size is specified as 117 cm2, sο:
New rectangle's surface area Equals (L - 3)
(L + 1) = L² - 2L - 3 = 117
When we simplify this sοlutiοn, we οbtain:
L² - 2L - 120 = 0
Using the quadratic fοrmula, we can answer this quadratic equatiοn:
L is equal tο (-b √(b² - 4ac)) / 2a.
where (a, b, and c) are (1, 2, and -120)
As a result, there are twο οptiοns:
L = 12 οr L = -10
Rectangles cannοt have negative lengths, sο we rule οut the negative sοlutiοn and determine that the initial rectangle's length was 12 cm.
We can determine the breadth by using the fοrmula fοr the width οf the initial rectangle:
Original rectangle's width is equal tο L – 4 (12 – 4), οr 8 centimetres.
As a result, a new rectangle is created by increasing the breadth by 5 cm, making the οriginal rectangle 12 by 8 cm in size.

Using graph it is seen that the solution of the linear system is found as (-1, 1).
Explain about graphing linear system?It is as easy to graph two straight lines as it is a set of linear equations. The (x,y) arranged pair where it two lines intersect will be the answer when the lines being graphed (cross).When the crossing point has integer coordinates, the graphing method using graph paper may be helpful. However, it is less useful if the coordinates are still not integers. Use an algebraic optimization technique or get out your graphing calculator if it looks that its intersection point does not sit on the intersections of the grids on the graph paper.The points for the two intersecting lines are-
Red points: (0, 5), (-1, 1), and (-3, -6)
Green points: (-3, 5), (-2, 3), (-1, 1), (0, -1), (1, -3), and (2, -5).
Graph of there points are plotted.
Thus, it is seen that the solution of the linear system graphically is found as (-1, 1).

The real number t corresponds to the point P(-2/1, 2/3) on the unit circle. To evaluate the six trigonometric functions of t, we can use the coordinates of point P.
Part 2 of 6:
cost= x-coordinate of point P = -2/1 = -2
Part 5 of 6:
sect= 1/cost= 1/(-2)= -1/2
The other four trigonometric functions can be evaluated similarly using the coordinates of point P:
sint= y-coordinate of point P = 2/3
cott= x-coordinate/y-coordinate = (-2/1)/(2/3) = -3
csc t= 1/sint= 1/(2/3)= 3/2
tant= y-coordinate/x-coordinate = (2/3)/(-2/1) = -1/3
Therefore, the six trigonometric functions of t are:
