A contractor better job at $750 for materials plus $43 per hour for labor. The total cost for the job can be modeled by C= 43H+ 750$.
Find the number of hours that he has for the job if the owner would like the total cost to be under $2000, rounded to the nearest hour.

Answers

Answer 1

The contractor has a maximum of 29 hours (rounded down) to complete the job while keeping the total cost under $2000.

To find the number of hours the contractor has for the job while keeping the total cost under $2000, we can use the given cost model equation: C = 43H + 750.

Since the owner wants the total cost to be under $2000, we can set up the inequality:

43H + 750 < 2000

Now, let's solve this inequality for H, the number of hours:

43H < 2000 - 750

43H < 1250

Dividing both sides of the inequality by 43:

H < 1250/43

To determine the maximum number of hours the contractor has for the job, we need to round down the result to the nearest whole number since the contractor cannot work a fraction of an hour.

Using a calculator, we find that 1250 divided by 43 is approximately 29.07. Rounding down to the nearest whole number, we get:

H < 29

Using the cost model equation C = 43H + 750, where C represents the total cost and H represents the number of hours, we set up the inequality 43H + 750 < 2000 to satisfy the owner's requirement of a total cost under $2000.

By solving the inequality and rounding down to the nearest whole number, we find that the contractor has a maximum of 29 hours to complete the job within the specified cost limit.

Determine the value of x in the equation. five sevenths times the quantity x plus 2 end quantity minus three sevenths times x equals two sevenths times the quantity x plus 5 end quantity

PLS HURRRY NEED THIS DUE BY 12 PM EDT

Answers

The equation does not have a unique solution for x. It is true for any value of x.

The given equation is:

(5/7)(x + 2) - (3/7)x = (2/7)(x + 5)

To solve for x, we'll first simplify both sides of the equation using the distributive property and combining like terms:

[(5/7)x + (5/7)(2)] - (3/7)x = [(2/7)x + (2/7)(5)]

Simplifying further:

(5/7)x + 10/7 - (3/7)x = (2/7)x + 10/7

Next, we'll collect the x terms on one side and the constant terms on the other side of the equation:

(5/7)x - (3/7)x - (2/7)x = 10/7 - 10/7

Combining like terms:

[(5/7) - (3/7) - (2/7)]x = 0

Simplifying further:

(0/7)x = 0

Any value of x will satisfy this equation since (0/7)x will always be zero.

Therefore, the equation does not have a unique solution for x. It is true for any value of x.

Step-by-step explanation:

since it already tells you what y equals it makes it easier to substitute the others take more work so the best first step is substituting for y

Answer:

Option D) Substitute for y in the first equation

Step-by-step explanation:

When solving for a system of equation, we always need 1 equation to have x or y already isolated by itself.  This makes it easy to substitute that variable into the other equation, solve, then substitute the other variable into another equation.

This will give us an ordered pair, known as the solution.

In this system, we have 2 equations.  In the first one, we have no variables isolated.  In the second one, we have y isolated on the left side of the equal sign.  This means we can take what y equals (3x+2) and substitute that in for y in the first equation.

The interval is given as

From x = x to x = x + h

The function is a quadratic function

This means that it does not have a constant average rate of change

So, we have

f(x) = 2x² + 9

f(x + h) = 2(x + h)² + 9

Next, we have

Rate = (2(x + h)² + 9 - 2x² - 9)/(x + h - x)

Answer:

Both are incorrect

Step-by-step explanation:

In the right triangle ΔABC, ∠ABC = 90 and two angles = 45,

∠ACB = ∠BAC = 45

Therefore, the sides opposite to these angles are equal

⇒ x = z

By  Pythagorean theorem,

x² + z² = y²

⇒ x² + x² = y²

⇒ 2x² = y² -----eq(1)

In the right triangle ΔABD,

∠ADB = 90

∠BAD = 45 (since ∠BAC = 45)

⇒ ∠ABD = 180 - 90 - 45

⇒ ∠ABD = 45

Since ∠BAD = ∠ABD = 45, the sides opposite to these angles are equal

⇒ AD = 3

Also since ΔABC is an isoceles triangle, BD bisects AC

⇒ AD = DC = AC/2 = y/2

⇒ y/ 2 = AD

⇒ y = 2AD

⇒ y = 2(3)

y = 6

From eq(1)

2x² = y²

⇒ 2x² = 6²

⇒ x² = [tex]\frac{6^2}{2}[/tex]

The algebraic expression (3x² - 6x)/(x² - 6x + 9) × (x² - x - 6)/(x² - 4) can be simplified to give 3x/(x - 3) which makes the option D correct.

Simplifying Algebraic expression

Simplification of an algebraic expressions is the process of writing an expression in the most efficient and compact way, that is in their simplest form, without changing the value of the original expression.

Simplifying the algebraic expression we have:

(3x² - 6x)/(x² - 6x + 9) × (x² - x - 6)/(x² - 4)

by factorization;

3x² - 6x = 3x(x - 2)

x² - 6x + 9 = (x - 3)(x - 3)

x² - x - 6 = (x - 3)(x + 2)

x² - 4 = (x + 2)(x - 2)

(3x² - 6x)/(x² - 6x + 9) × (x² - x - 6)/(x² - 4) = 3x(x - 2)/(x - 3)(x - 3) × (x - 3)(x + 2)/(x + 2)(x - 2)

cancel out common factors we have;

(3x² - 6x)/(x² - 6x + 9) × (x² - x - 6)/(x² - 4) = 3x/(x - 3)

Therefore, the algebraic expression (3x² - 6x)/(x² - 6x + 9) × (x² - x - 6)/(x² - 4) can be simplified to give 3x/(x - 3)

What is the range of the function y=e^4x

Answers

The function [tex]y = e^4x[/tex] has a range of (0,∞). Here's why: The range of a function is the set of all possible output values.

To determine the range of a function, you must examine its graph or find the output for every input value.

In this case, [tex]y = e^4x[/tex] is an exponential function with a base of e, which is a constant that is approximately equal to 2.71828.

The exponential function [tex]y = e^x[/tex] is always positive.

Therefore, [tex]y = e^4x[/tex] will also be positive for all values of x.

As a result, the function's range will start at 0 and continue up to positive infinity, but will not include 0.This can be shown by graphing the function or plugging in various values of x to see what output values result. However, by knowing the properties of exponential functions, you can determine the range of[tex]y = e^4x[/tex] without graphing it.

Answers

The statements that are true are:

A. The domain for f(x) is the set {-2, -1, 0, 1, 2, 3, 4, 5, 6).

C. f(-1) = 6

To determine the truth of each statement, we need to analyze the given table of values for the function f(x).

A. The domain for f(x) is the set {-2, -1, 0, 1, 2, 3, 4, 5, 6).

The x-values listed in the table are -2, -1, 0, 1, 2, 3, 4, 5, and 6. These are the inputs for the function, and therefore, they represent the domain of f(x). Thus, statement A is true.

B. The range for f(x) is all real numbers.

Looking at the y-values listed in the table for f(x), we can see that the range of f(x) is from 5 to 13. It does not include all real numbers, so statement B is false.

C. f(-1) = 6

From the table, we can see that when x = -1, f(x) = 6. Thus, statement C is true.

D. f(5) = -2

There is no entry in the table for f(5), so we cannot determine the value of f(5) from the given information. Therefore, statement D is false.

The average weight of 12 eggs is 32 gms. Two of them weighing 35 and 37 gms respectively are broken. Find the average weight of the remaining 10.​

Answers

Answer:

  31.2 g

Step-by-step explanation:

You want to know the average weight of the remaining eggs if two from a dozen with average weight 32 g are broken, and their weights are 35 and 37 g.

Relative to average

The two broken eggs differ from average by ...

  (35 -32) +(37 -32) = 3 +5 = 8 . . . . . grams

The remaining eggs must differ from that average by the opposite amount, a total of -8 g.

Distributed over 10 eggs, this difference is -0.8 g, so the average weight of the remaining eggs is 32 -0.8 = 31.2 g.

The average weight of the remaining 10 is 31.2 g.

New sum

The average weight is the sum of all weights divided by the number of eggs:

  avg = W/N

  W = N·avg = 12·32 g = 384 g

The new sum of weight will be this amount less the weights of the broken eggs:

  W' = 384 g -35 g -37 g = 312 g

The new number of eggs is 2 fewer: N' = 12 -2 = 10.

So, the new average weight is ...

  avg' = W'/N' = 312 g/10 = 31.2 g

__

Additional comment

By working with the differences from average, we don't have to figure the old and new sums. We're only concerned with the way that sum changes, and the average amount of that change. Often, this means we can solve the problem using only mental arithmetic.

What the meaning of "well-ordered by ∈"?

Answers

The phrase "well-ordered by ∈" refers to a specific kind of ordering or relation on a set using the element-of symbol (∈). In set theory, the symbol "∈" represents membership, indicating that an element belongs to a set.

The meaning of "well-ordered by ∈"

A well-ordering is a particular type of total order, where every non-empty subset of the set has a least element. In other words, for any subset of the set, there is always a smallest element in that subset according to the ordering relation.

When we say that a set is "well-ordered by ∈," it means that the elements of the set are arranged in a specific order such that the membership relation (∈) satisfies the properties of a well-ordering. This implies that every non-empty subset of the set has a smallest element with respect to the membership relation (∈).

The best answer choice among the given options is O 15 m², as none of the provided options match the correct Ccalculation.

To find the area of a rhombus, we need the lengths of the diagonals. In this case, the lengths of the diagonals are not provided. However, we can use the given information to determine the area based on the side lengths.

A rhombus is a quadrilateral with all sides of equal length, so the given side lengths of 5.5 m and 2 m can help us find the area.

We know that the diagonals of a rhombus bisect each other at right angles, dividing the rhombus into four congruent right triangles. Each side of the rhombus is the hypotenuse of one of these triangles.

Given that the side length is 5.5 m, we can consider one of these right triangles. One leg of the right triangle is half of the side length, which is (5.5 m)/2 = 2.75 m. The other leg of the triangle is the length of the diagonal, which is unknown.

Using the Pythagorean theorem, we can find the length of the diagonal:

(diagonal)^2 = (leg)^2 + (leg)^2

(diagonal)^2 = (2.75 m)^2 + (2 m)^2

(diagonal)^2 = 7.5625 m² + 4 m²

(diagonal)^2 = 11.5625 m²

diagonal ≈ √11.5625 m ≈ 3.4 m (rounded to the nearest tenth)

Since the diagonals of a rhombus are perpendicular bisectors of each other, the length of the other diagonal would also be approximately 3.4 m.

Now, we can calculate the area of the rhombus using the formula: area = (diagonal1 * diagonal2) / 2

area = (3.4 m * 3.4 m) / 2

area = 5.8 m²

The area of the rhombus is approximately 5.8 m².

The best answer choice among the given options is O 15 m², as none of the provided options match the correct area calculation.
