After solving the given numbers with (PEMDAS) 11 - 11 x 11 + 11 = we get the answer of -88.

To solve 11-11x11+11, we need to use the order of operations, which is a set of rules that dictate the order in which mathematical operations should be performed. The order of operations is:

Parentheses

Exponents

Multiplication and Division (from left to right)

Addition and Subtraction (from left to right)

Using this order of operations, we can simplify the expression as follows:

11 - 11 x 11 + 11

= 11 - 121 + 11 (since multiplication should be done before addition and subtraction)

= -99 + 11

= -88

Therefore, the value of 11-11x11+11 is -88.

In general, when simplifying expressions, it is important to follow the order of operations to ensure that you get the correct answer. Additionally, it is always a good idea to check your work by plugging the answer back into the original expression and making sure that it is correct.

It would take the apprentice alone 11 hours to complete a kitchen island, the same amount of time it took the cabinet maker and apprentice together.

When the cabinet maker and apprentice work together, they are able to complete the kitchen island in 8 hours. This implies that the apprentice is able to do their portion of the work in 3 hours, while the cabinet maker does their portion in 8 hours. Therefore, if the apprentice were to work on the kitchen island alone, it would take them 11 hours to complete it, the same amount of time it took the cabinet maker and apprentice together. This is because the apprentice does not have the same level of experience and expertise as the cabinet maker, so they are not able to complete the same amount of work in the same amount of time as the cabinet maker. The cabinet maker is able to work faster and more efficiently, which is why they are able to complete the kitchen island in 8 hours, while the apprentice would need 11 hours to complete the same task.

Answer:

x = - 1 , x = [tex]\frac{1}{3}[/tex]

Step-by-step explanation:

assuming you require the solution to the equation

x(3x - 1) + (3x - 1) = 0 ← factor out (3x - 1) from each term

(3x - 1)(x + 1) = 0

equate each factor to zero and solve for x

x + 1 = 0 ⇒ x = - 1

3x - 1 = 0 ( add 1 to both sides )

3x = 1 ( divide both sides by 3 )

x = [tex]\frac{1}{3}[/tex]

The final answer is: cos(α + β) = (3i - √190) / 10.

\( \alpha \) and \( \beta \) are first quadrant angles with \( \cos (\alpha)=\frac{\sqrt{5}}{10} \) and \( \sin (\beta)=\frac{\sqrt{10}}{10} \).

What is Algebraic expression ?

Algebraic expression can be defined as combination of variables and constants.

The appropriate hypotheses for this test are:

H0: p = 0.28 (the proportion of all high school students who work a part-time job during the school year is 0.28)

Ha: p > 0.28 (the proportion of all high school students who work a part-time job during the school year is greater than 0.28)

This is because the guidance counselor is interested in whether the proportion of all high school students who work part-time jobs during the school year is greater than 0.28, which was the proportion a decade ago. The null hypothesis states that the proportion is 0.28, and the alternative hypothesis states that it is greater than 0.28. Since the alternative hypothesis is one-sided (greater than), this is a one-tailed test.

Option B correctly states the null and alternative hypotheses with the appropriate population proportion in the null hypothesis and the direction of the alternative hypothesis.

Answer:

  C. The graph of g(x) is wider than f(x) and is shifted to the left 4 units and down 3 units.

Step-by-step explanation:

You want to know the transformations needed to form g(x) = 1/2(x+4)^2 -3 from f(x) = x^2.

The transformations ...

  f(x) ⇒ g(x) = c·f(x -h) +k

represent vertical expansion by a factor of 'c', right shift by 'h' units, and an upward shift of 'k' units.

Here, we have c=1/2, h=-4, k=-3. These mean the function f(x) has been vertically compressed to 1/2 its original height, and shifted left 4 and down 3.

The vertical compression will cause the graph to appear to be wider for any given distance above the vertex.

Answer:

To solve the equation 3x + 5y = 500 for x, we need to isolate x on one side of the equation. First, we can subtract 5y from both sides to get 3x = 500 - 5y. Then, we can divide both sides by 3 to get x = (500 - 5y) / 3.

It might be helpful to rewrite the equation in terms of one variable if we want to solve for one unknown quantity in terms of another. In this case, rewriting the equation in terms of x allows us to see how many child tickets the school needs to sell to raise exactly $500, given any number of adult tickets sold. This can be useful in planning and budgeting for the carnival.

Step-by-step explanation:

The equation of the line that is parallel to the line y = x 4 and passes through the point (6, 5) is y = x - 1

The line y = x + 4 has a slope of 1 because it is in the form y = mx + b, where m is the slope of the line. To find a line parallel to this line, we need to use the same slope of 1.

Now, we can use the point-slope form of a linear equation to find the equation of the line that passes through the point (6, 5) with a slope of 1:

y - y1 = m(x - x1)

where m = 1, x1 = 6, and y1 = 5.

Plugging in the values, we get:

y - 5 = 1(x - 6)

Simplifying, we get:

y - 5 = x - 6

Answer:

a) To calculate the total amount to be repaid, we need to add the interest to the principal amount.

The formula for simple interest is:

I = P * r * t

where I is the interest, P is the principal amount, r is the interest rate per year, and t is the time in years.

In this case, P = $9000, r = 12% = 0.12, and t = 5 years.

So, the interest on the loan is:

I = $9000 * 0.12 * 5 = $5400

The total amount to be repaid is:

Total amount = Principal + Interest = $9000 + $5400 = $14400

Therefore, the total amount to be repaid is $14,400.

b) To calculate the monthly repayment amount, we need to divide the total amount to be repaid by the number of months in 5 years (60 months), since the repayments are spread equally over 5 years.

Monthly repayment amount = Total amount to be repaid / Number of months

= $14,400 / 60

= $240

Therefore, the monthly repayment amount if the repayments are spread equally over the 5 years is $240.

The instantaneous rate of change at x=1.

In mathematics, a function is a relation between sets that assigns to each element of a given set, exactly one element of a related set. This relationship between two sets is called a mapping, and it is commonly represented using a function notation. Functions are used to describe mathematical relationships and are studied extensively in mathematics, computer science, and other related fields.

The instantaneous rate of change at x=1 can be estimated using the concept of derivatives. A derivative is a mathematical operation that measures the rate at which a function changes with respect to its input. In this case, the derivative of the given function will measure the rate at which the function changes with respect to the input x=1.

The derivative of a function can be calculated using the formula:

f′(x)=limh→0[f(x+h)-f(x)]/h

Where f′(x) is the derivative of the function, f(x) is the function, and h is a small number close to zero.

To calculate the derivative of the function at x=1, we can plug in x=1 into the formula:

f′(1)=limh→0[f(1+h)-f(1)]/h

By calculating this limit, we can estimate the instantaneous rate of change at x=1.

[tex]t_{goal} = (1/r) \times ln(C_{goal}/C_0)[/tex]

Here, ln denotes the natural logarithm. This equation gives us the value of t for which cigarette consumption reaches the goal amount C_goal.
