Step-by-step explanation:

If it costs $7.80 to manufacture the t-shirt, then a 110% markup would mean selling it for 1.1 times the manufacturing cost:

Price = 1.1 x $7.80 = $8.58

So Marcos should sell each t-shirt for $8.58 to customers.

The approximate distance across the lake is 6.7 kilometers, which is closest to option D.

What is Pythagorean theorem?

The Pythagorean theorem is a fundamental concept in mathematics that relates to the lengths of the sides of a right triangle.

To solve this problem, we can use the Pythagorean theorem, which states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.

In this case, the distance across the lake is the hypotenuse of a right triangle, and the distances 6 km and 3 km are the lengths of the other two sides. Therefore, we can write:

distance across the lake = √(6 km)² + (3 km)²

distance across the lake = √(36 km² + 9 km²)

distance across the lake = √45 km²

distance across the lake ≈ 6.7 km

Therefore, the approximate distance across the lake is 6.7 kilometers, which is closest to option D.

By the Mean Value Theorem, there exists a number c in (1, 7) such that ƒ'(c) = 2/c and 2/c = ln7 / 6, and c ≈ 0.909.

The Mean Value Theorem (MVT) states that if a function ƒ(x) is continuous on the closed interval [a, b] and differentiable on the open interval (a, b), then there exists a number c in (a, b) such that:

ƒ'(c) = [ ƒ(b) - ƒ(a) ] / (b - a)

ƒ(x) = 2lnx - 8 is continuous on the closed interval [1, 7], since it is the sum and composition of continuous functions.

ƒ(x) = 2lnx - 8 is differentiable on the open interval (1, 7), since its derivative ƒ'(x) = 2/x is defined and continuous on (1, 7).

Therefore, the Mean Value Theorem can be applied to ƒ(x) on [1, 7]. To find the value of c, we need to solve the equation:

ƒ'(c) = [ ƒ(b) - ƒ(a) ] / (b - a)

Substituting the given values, we get:

2/c = [ 2ln7 - 2ln1 ] / (7 - 1)

2/c = ln7

c = 2 / ln7

c ≈ 0.909

Therefore, by the Mean Value Theorem, there exists a number c in (1, 7) such that ƒ'(c) = 2/c and 2/c = ln7 / 6, and c ≈ 0.909.

Step-by-step explanation:

Using Euler's method with step size 0.2, we estimate that y(0.6) ≈ 0.6024.

What is Euler's method ?

Euler's method is a simple numerical method used to approximate the solution of a first-order ordinary differential equation (ODE) with a given initial value. The method is based on the idea of approximating the solution by taking small steps along the direction of the derivative of the solution.

To use Euler's method, we need to take steps of size 0.2 from x=0 up to x=0.6, and use the derivative y' = cos(x + y) to approximate the value of y at each step.

We start by setting up a table:

x y y' = cos(x+y) y(i+1) = y(i) + h*y'

0.0 0.0 cos(0) = 1 0.2 * 1 + 0 = 0.2

0.2 0.2 cos(0.2+0.2) 0.2 * 1.981 = 0.3962

0.4 0.3962 cos(0.4+0.3962) 0.2 * 1.9774 = 0.3955

0.6 0.7919 cos(0.6+0.7919)

To estimate y(0.6), we need to complete the last row of the table. We have:

y(0.2) = 0.21 + 0 = 0.2

y(0.4) = 0.21.981 + 0.2 = 0.3962

y(0.6) ≈ 0.3955 + 0.2*cos(0.6+0.7919) ≈ 0.6024

Therefore, using Euler's method with step size 0.2, we estimate that y(0.6) ≈ 0.6024.

So, after 320 minutes, the car will have covered 200 miles.

In both the US customary and British imperial systems of measurement, a mile is a unit of length or distance. It is measured in yards or 5,280 feet. Approximately 1.609 km make up one mile.

A method of measurement known as the imperial system was created in England in the 12th century and afterwards adopted by other nations. It is often referred to as the Imperial Units or the British Imperial System. The system comprises units for weight, such as ounces, pounds, and tons, volume, and length (such as inches, feet, and miles). (such as fluid ounces, pints, quarts, and gallons). Despite the fact that many other nations have switched to the metric system, the imperial system is still in use in some nations, including the United States and the United Kingdom.

The autonomous vehicle covers **0.625 miles per minute**. (50 miles in 80 minutes).

After 320 minutes, we may multiply the rate by the time to get how many miles the car will have travelled:

0.625 miles/minute × 320 minutes = **200 miles**

0.625 miles per minute divided by 320 minutes equals 200 miles.

Javier's total property tax bill is $4,750.06. By solving the question.

How to solve the question?

To calculate Javier's property tax bill, we need to use the assessed value of his home and the millage rates for each tax district.

First, we need to convert the millage rates to decimal form. To do this, we divide each millage rate by 1,000:

School district millage rate = 6.3 / 1,000 = 0.0063

City millage rate = 6.9 / 1,000 = 0.0069

County millage rate = 7.1 / 1,000 = 0.0071

Next, we need to calculate the tax for each district by multiplying the assessed value of Javier's home by the millage rate for that district:

School district tax = $234,000 x 0.0063 = $1,475.20

City tax = $234,000 x 0.0069 = $1,615.46

County tax = $234,000 x 0.0071 = $1,659.40

Finally, we add up the tax for each district to get Javier's total property tax bill:

Total property tax bill = $1,475.20 + $1,615.46 + $1,659.40 = $4,750.06

Therefore, Javier's total property tax bill is $4,750.06.

Given the information, the probability that a response is between the ages of 18 and 29 and 30 or older is, respectively, 0.536 and 0.654. There is a 0.265 percent chance that they will say yes—that global warming will affect them over their lifetime. Concern over global warming also seems to vary across people aged 18 to 29 and those over 30.

Probability is the ratio of favourable events to all other potential outcomes in a circumstance. The symbol x can be used to denote how many successful outcomes there were in an experiment with 'n' outcomes. The formula below can be used to determine a given event's probability.

Positive Results/Total Results = x/n = Probability (Event)

The likelihood that a respondent between the ages of 18 and 29 believes that there will be no significant threat from global warming in his or her lifetime is:

P (18-29 and no) = 293/(134 + 293 + 117) = 0.536

The likelihood that a respondent who is 30 years of age or older believes that there will be no significant threat from global warming in his or her lifetime is:

P (30+ and no) = 432/(131 + 432 + 178) = 0.654

The likelihood that a randomly chosen respondent will select "yes"—that is, that they will experience the effects of global warming throughout their lifetimes—is:

P(Yes) = (134 + 131)/(134 + 131 + 293 + 432 + 117 + 178) = 0.265

Yeah, it does seem that younger people (18–29) are less concerned about global warming than older people (30+). In comparison to respondents aged 18 to 29, the likelihood that a respondent aged 30 or older believes that global warming will not constitute a severe hazard during their lifetime is higher (0.654). (0.536). According to this, respondents who are older are less concerned about global warming than respondents who are younger.

Answer:

  [tex]f^{-1}(x)=4-(x-10)^2[/tex]

Step-by-step explanation:

You want the inverse function for f(x) = √(4-x) +10 and the domain of the inverse function.

The inverse function for y = f(x) is the equation x = f(y) solved for y.

  x = √(4 -y) +10 . . . . . . . x = f(y)

  x -10 = √(4 -y) . . . . . . subtract 10

  (x -10)² = 4 -y . . . . . . . square

  y = 4 -(x -10)² . . . . . . . .add y-(x-10)²

  f^-1(x) = -(x -10)² +4

The domain and range are swapped between a function and its inverse. That is, the domain of f^-1(x) will be the range of f(x).

The domain of f(x) is values of x at most -4. For those values, the range of f(x) is values of f(x) at least +10.

The domain of f^-1(x) is [10, ∞).

__

Additional comment

A function and its inverse are reflections of each other across the line y=x. You will notice that the domain restriction on f^-1(x) ensures it is the half of the parabola that is the reflection of f(x).

The value of the inverse of the function is f⁻¹(x) = 4 - (x - 10)². The domain is: Domain: R (all real numbers).

A technique for figuring out whether a function has an inverse is the horizontal line test. Applying this test requires visualising a horizontal line being drawn at a specific location on the function's graph. The function has an inverse if the line only touches the graph once. The function does not have an inverse if the line crosses the graph more than once.

The horizontal line test is effective because a function can only have an inverse if each input value corresponds to a distinct output value, according to intuition.

To determine the inverse of the function replace (x) with y:

y = √(4-x) + 10

Switch the variables as follows:

x = √(4-y) + 10

Isolating the value of y we have:

x - 10 = √(4-y)

(x - 10)² = 4 - y

y = 4 - (x - 10)²

Now, for the given function the value is true for all real numbers, thus the domain is:

Domain: R (all real numbers)

Hence, the value of the inverse of the function is f⁻¹(x) = 4 - (x - 10)². The domain is: Domain: R (all real numbers).

The total area is 1570 square units.

Explain area

Area refers to the measurement of the size of a two-dimensional surface. It is typically expressed in square units, such as square meters or square feet. The area of a shape can be calculated by multiplying its length by its width, or by using specific formulas for more complex shapes. Area is an important concept in geometry and is used in many real-life applications, such as calculating the area of a room or a piece of land.

According to the given information

Here the base of the right triangle is 20 and the hypotenuse is 29, so we can set up the equation:

29² = 20² + h²

where h is the height of the triangle(length of dotted line) that we want to find.

Simplifying and solving for h, we get:

h² = 29² - 20²

h² = 841 - 400

h² = 441

h = √(441)

h = 21

Therefore, the length of the dotted line is 21 units

Now,

The area of a right triangle is given by the formula A = (1/2)bh, where b is the base and h is the height. So, the area of the right triangle with base 20 and height 21 is:

A_triangle = (1/2)(20)(21) = 210

The area of a right trapezium is given by the formula A = (1/2)(a+b)h, where a and b are the parallel sides and h is the height. So, the area of the right trapezium with a longer side of 55, smaller side of 21, and height of 40 is:

A_trapezium = (1/2)(55+21)(40) = 1360

Therefore, the total area of the right triangle and right trapezium is:

A_total = A_triangle + A_trapezium = 210 + 1360 = 1570

Answer:  8cm

Step-by-step explanation: sorry if im wrong

Answer:

7 cm

Step-by-step explanation:

To find the length of the rectangle, we can use the formula for the perimeter of a rectangle:

Perimeter = 2 × Length + 2 × Width

We are given that the width is 5cm and the perimeter is 24cm.

Substituting these values into the formula, we get:

24 = 2L + 2(5)

Simplifying the right side, we get:

24 = 2L + 10

Subtracting 10 from both sides, we get:

14 = 2L

Dividing both sides by 2, we get:

L = 7

Therefore, the length of the rectangle is 7cm.

After simplification of the given expression, the resultant answer is (B) −3.03u + (−8).

Mathematical expressions consist of at least two numbers or variables, at least one arithmetic operation, and a statement.

It's possible to multiply, divide, add, or subtract with this mathematical operation.

Keep in mind that terms can be coefficients, constants, or variables. So, 1+1 is a straightforward example of an expression.

This equation has one operation, two constant terms, and (addition). x3 is another illustration.

So, the given expression is:

(4.57u − 14) − (−6 + 7.6u)

Then, solve as follows:

4.57u - 14 - ( -6 + 7.6u)

4.57u - 14 + 6 - 7.6u

4.57u - 7.6u = -3.03u AND -14 + 6 = -8

-3.03u - 8 (or -3.03u + (-8) )

Therefore, after simplification of the given expression, the resultant answer is (B) −3.03u + (−8).

The y-values of the quadratic equation for x = {1, 2, 3, 4} are {5, 11, 19, 29}.

What is quadratic equation?

A quadratic equation is a type of polynomial equation of degree 2, which means it contains a variable raised to the second power (i.e., x²). It has the standard form of ax² + bx + c = 0, where a, b, and c are constants and x is the variable. The coefficient a cannot be equal to zero, as this would result in a linear equation.

Quadratic equations can have one or two real solutions, depending on the discriminant (b² - 4ac) of the equation. If the discriminant is greater than zero, the equation has two real solutions. If the discriminant is equal to zero, the equation has one real solution. If the discriminant is less than zero, the equation has no real solutions (but has two complex solutions).

To find the y-values of the quadratic equation y = x² + 3x + 1 for x = {1, 2, 3, 4}, we simply substitute each value of x into the equation and evaluate.

For x = 1, y = 1² + 3(1) + 1 = 5.

For x = 2, y = 2² + 3(2) + 1 = 11.

For x = 3, y = 3² + 3(3) + 1 = 19.

For x = 4, y = 4² + 3(4) + 1 = 29.

Therefore, the y-values of the quadratic equation for x = {1, 2, 3, 4} are {5, 11, 19, 29}.
